Robomow® - Safety Features

1. Child Guard / Safety Guard

This menu option offers a safety feature to help prevent children or others not familiar with the safe operation of the mower to operate it freely.

2. Lift Sensor

There is a sensor located on the front of the mower. In the event the mower is raised from its resting position on the ground during blade operation, the blades will stop rotating immediately (< 1 second).

3. Sensor Equipped Bumpers

The front and rear bumpers are equipped with contacts that will activate when the mower strikes a solid, fixed object. When the bumper sensor is activated, the mower stops the blades immediately and reverses itself away from the obstacle.

4. Emergency Stop Switch

The STOP button is located on the Manual Controller. Pressing this button at any time during operation will stop all mower movement and the rotation of the blades immediately.

5. Two-Step Operator Presence Control

While in manual mode, it requires two independent finger actions in order to engage the mower blades. Once engaged, the mower blade button must remain depressed to continue blade operation. Once released, the two-step engagement process must be repeated.

6. Sealed Batteries

The batteries that operate the Robomow ^® are completely sealed and will not leak any type of fluids, regardless of position.

7. Perimeter Switch and Perimeter Wire

The Robomow ^® cannot operate without a perimeter wire installed and activated through the Base Station/ Perimeter Switch. In the event the Perimeter Switch is turned off or otherwise fails to function, the Robomow ^® will stop operating.

8. Automatic departure warning alert

When the mower is scheduled to depart the Base Station automatically per a scheduled time, a warning sound and the operating lamp will activate 5 minutes prior to departure. This is a warning notification to clear and inspect the area.

How It Works

• A one-time setup is required before operating Robomow; a small wire, called the perimeter wire, is placed around the edge of the lawn and any other areas where you do not want the mower to enter.
• Small pegs are supplied with Robomow and they are used to fasten and hold the perimeter wire to the ground, below grass level; the wire will soon disappear under the growth of new grass and will not visible.

• The Base Station is placed along the perimeter wire and it has two main functions:

• To generate a small signal along the perimeter wire (very low voltage);

• To charge Robomow batteries.

• After completing the one-time set-up of wire around the lawn including the Base Station set the weekly program and forgets about mowing for the entire season!
- Robomow will leave the Base Station on the day and time scheduled in the automatic weekly program; it will mow the lawn and will drive back for charging in the Base Station to be ready for the next operation.
- When Robomow leaves the Base Station it automatically starts the signal carried through the Base Station; the signal creates a virtual wall, which is visible only to the Robomow, keeping it inside the lawn preventing it to cross over area where you do not want it to enter.

Base Station generates a signal along the wire and is used to charge Robomow batteries Trees large enough to allow Robomow to bump into; do not require a perimeter wire around it Perimeter Wire as a virtual wall, visible only to Robomow Robomow detects the signal and changes direction as it reaches the wire

Chapter 1 Planning

Before starting the setup, please read this chapter fully and watch the setup DVD. This will help you determine the best location for the Base Station, for the perimeter wire layout, or for the Perimeter Switch.

1.1 Determine Base Station location

Robomow's Base Station is placed along the Perimeter Wire. This is where the wire "loop" starts and ends. The Base Station has two main functions:

• It generates a small signal along the perimeter wire (very low voltage), which serves as an “invisible wall” setting the lawn boundaries for Robomow.
• It charges Robomow's batteries.

After completing the one-time set-up of the Perimeter Wire and the Base Station, a weekly program is set. That's when Robomow does your mowing for the entire season!

Robomow leaves the Base Station on the day and time scheduled in the automatic weekly program. It mows the lawn and it returns to the Base Station for recharging.

First, you decide where the Base Station will be placed...

■ Inside the lawn area, along its outer edge.

Or:

■ Outside the lawn area

1.1.1 Consider the following in order to choose the best location:

○ If the lawn has more than one zone, set the Base Station within the largest plot or zone.
○ Make the Base Station invisible to the street.
○ Prefer a shady spot.

This will extend battery lifetime

○ Place the Base Station on a relatively level ground.
○ Do NOT place it on a slope.
○ Place the Base Station at least 1 meter from corners.
○ Place the Base Station away from sprinkler heads.

Water or rain does not harm Robomow. However, we recommend a distance from sprinklers for maximum protection.

Option A - Internal setup (Inside the lawn along the outer edge)

se Base and. Base Zone Base Station Zone A Bansers. ds. er, we

1.1.2 If Base Station is to be located outside the lawn area

External setup of the Base Station allows the Base Station to be located outside the lawn area, close to its edge.

Consider the following in order to choose the best external location:

○ Choose a place close to the lawn edge.
○ The passing between the lawn and the Base Station should be smooth, with no height differences.

This will enable Robomow to follow the wire smoothly to its Base Station.

The surface of the external area should be hard (e.g. a sidewalk, firm ground). It should not be sandy or stony.

This will prevent Robomow from slipping or getting stuck.

Option B - External setup (Outside the lawn)

Base Station 's Base . a

1.1.3 Determine location of Power Supply

☐ The Base Station should be close enough (15 m/50 ft) to a wall electrical socket (230V / 120V). The indoor Power Supply unit will be connected to it.
- Robomow's 15 m (50 ft) low voltage cable connects to the power supply unit. The length of the low voltage cable must NOT be changed.
○ Select the right location for the power supply unit:

Power supply Max 15 m (50 ft) The Fence should be inside lawn 15 m (50 ft) extension cord (low voltage)

The power supply is suitable for outdoor use, yet it is required placing it in a sheltered place, dry location, which is well ventilated and not exposed to direct sunlight.

1.2 Planning the Perimeter Wire's layout

The Perimeter Wire functions as an "invisible wall" for Robomow. It sets the boundaries of lawn zones and it surrounds specific areas where you do not want Robomow to enter.

The Perimeter wire is held to the ground with small pegs, supplied with Robomow. Soon after setting, the wire will become invisible under the growth of new grass.

As soon as Robomow starts operating, it turns on a signal that runs along the Perimeter Wire. This signal keeps Robomow within its working zones and away from preset demarcated areas.

1.2.1 Is your lawn a single contiguous area?

If grass areas are contiguous, Robomow will automatically mow all zones tracking the Perimeter Wire you set around the lawn.

1.2.2 Does your lawn have more than one zone?

If your lawn areas are separated by fences, sidewalks or other objects, you may wish to set Robomow to work in more than one zone. Create separate zones in more than one way:

☐ You may use one Perimeter Switch or one Base Station: Connect all zones together in one long loop of the Perimeter Wire. The Perimeter wire can be as long as 500 meters (1650 ft) in one loop

Or.

You may set both Base Station and a Perimeter Switch: Connect one or more zones to the Base Station. In addition, connect other zones to a Perimeter Switch available as an accessory for City 120.

The Perimeter Switch may be moved from one zone to another.

To switch zones, Robomow will be driven or carried to the proper location.

Base Station Min 1 m (3 ft) Perimeter Switch >1.5 m (4.9 ft)

Base Station Base Zone Zone A Zone B Maximum length of implied to the

While the picture shows two wires separate, they should be adjacent

Determining the distance between adjacent perimeter wires:

1. If lawns are installed by the same perimeter wire that is connected to the same source (Base Station / Perimeter Switch), then it is enough to keep a distance of one meter between the wires to prevent interference in operation.

2. If lawns are installed using different perimeter wires that are not connected, and each has its own source (Base Station / Perimeter Switch), then one of the following is required:

a. Maintain a minimum distance between the wires (30-50cm) to allow overlap between mowing zones, but synchronize between the mowing schedules to confirm there will not be interference between the zones. OR
b. Keep two meters between the perimeter wires with no need to synchronize between the operation schedules.

1.2.3 Will Robomow be driving through a narrow pass in order to move between two connected zones?

A narrow pass is part of the lawn that connects two larger zones. The width of this pass determines how it should be set-up.

If the pass... Setup:
Is walled (fence, building, etc) and width is More than 2.00m (6.6 ft)OREdge of pass is an open area and width is more than 1.70m (5.6 ft)	Regular setup, as Robomow can navigate between the areas while mowing.(Refer to paragraph 2.1.2).
Is walled (fence, building, etc) and width is 1.5m – 2.00m (4.9 – 6.6 ft)OREdge of pass is an open area and width is 1.1m – 1.70m (3.6 – 5.6 ft)	Set as a “Narrow Pass”: Robomow will drive through the pass, but will NOT get across while mowing each area.(Refer to paragraph 2.2.2).
Is walled (fence, building, etc) and width is smaller than 1.5m (4.9 ft)OREdge of pass is open area and width is smaller than 1.1m (3.6 ft)	Pass is too narrow.Set the areas as 2 separate zones.

Pass wide enough. Robomow can effectively navigate between the two areas while mowing the lawn.

We want Robomow to enter the narrow pass in order to move between these zones.

But, we do not want it to cross the pass while mowing each one of them.

See Chapter 2, Base Station and Perimeter Wire Setup

Note: Narrow Passes require special setting of Entry Points in order to start mowing in the adjacent areas (see Chapter 7, Setting Robomow and using Advanced Features)

Narrow Pass: Robomow will drive through the pass, but will NOT get across while mowing each area.

1.2.4 Are there obstacles in Robomow's mowing path? (Setting "Perimeter Islands")

Obstacles such as flowerbeds, ponds, or small trees can be protected from Robomow by setting "Perimeter Islands". Perimeter Islands are demarcated areas of the lawn, where Robomow does not enter.

Obstacles that are vertical, relatively rigid and higher than 15cm (6 inches), such as trees, phone or power poles, do NOT need boundaries. Robomow will turn when it collides with these obstacles. However, for the gentlest and most silent operation, you may prefer to create Perimeter Islands around all fixed objects in the working area.

○ If areas with obstacles are grouped closely together less than 1.5m (4.9 ft), they should be demarcated by a single, continuous, Perimeter Island.

Chapter 2 Base Station and Perimeter Wire Setup

Recommendation, before you start:

During setup, you will insert pegs into the ground. To make this task smoother, we recommend you mow your lawn and water it before starting.

Getting Ready

Confirm all parts needed for setup are within reach (refer to 'What's in the Box, Introduction).

In addition, you will use the following tools:

Hammer Combination Pliers Small flat and Philips screwdrivers

2.1 Perimeter Wire Setup

Before you start the setup, you should have a plan for the Perimeter Wire layout and for the location of the Base Station.

Laying the Perimeter Wire for the Internal setting of the Base Station is different from the External setting.

Hand holding a green plastic film reel with a small object inside, no visible text or symbols

2.1.1 Starting Point: Perimeter Wire at the Base Station area.

Place the Base Station, according to your plan, with its fence facing the inner lawn area. Pull the plot connector and the wire connected to it out of the plastic covering.

Do NOT remove the wire spool from its covering. The plastic covering is the dispenser for the wire.

○ If setting of Base Station is Internal (inside lawn)

♦ Peg the beginning of the wire to the ground, where Base Station will be located.
◆ Pull out 30 cm (12 inches) of wire and leave it loose at the Base Station location. Later, at the end of the setup this part of the wire will close the Perimeter Wire loop.
◆ Start laying the wire in a counter-clockwise direction.
◆ Continue to pull the Perimeter Wire out of its covering, laying it loosely as you walk along the lawn edge.

Perimeter Wire – do not remove the plastic covering Leave 30 cm (12 inches) starting point Counter-clockwise direction of wire layout

○ If setting of Base Station is external (outside lawn)

♦ Peg the beginning of the wire to the ground, at a distance of 1m (3.3 feet).
◆ Pull out 40 cm (16 inches) of wire and leave it loose at the Base Station location. This allows for later adjustments of the Base Station.
◆ Start laying the wire in a counter-clockwise direction at the external area of the Base Station.

• Continue laying the wire for at least 30 cm (12 inch) away from the lawn.
• Set a Narrow Pass, 20 cm (8 inches) wide, in the direction of the lawn, until the wire is 30 cm (12 inches) inside the lawn.

◆ Continue to pull the Perimeter Wire out of its covering, laying it loosely as you walk along the lawn edge.

Continue for at least 30 cm (12") away from lawn. Leave 40 cm (16") of coil at starting point, for later adjustments. Starting point - 1 m (3.3 ft) from lawn's edge Set a narrow pass of 20 cm (8") towards lawn. Continue until wire is 30 cm (12") inside lawn. Continue laying the wire, using RoboRuler along edges.

2.1.2 Laying the Perimeter Wire

The Perimeter Wire is secured to the ground by the pegs supplied with Robomow. Insert pegs every few meters and at corners. At this early stage set a minimum number of pegs. Later, after testing the wire setup, you will insert all necessary pegs.

○ Continue laying the wire, according to your plan. Gradually pull it out of its dispenser and lay it loosely as you are moving in a counterclockwise direction.
○ After uncoiling sections of wire, before inserting pegs, use the RoboRuler to determine the distance of the wire from lawn edge or obstacles.

If Outer Area Adjacent To Lawn... Distance Of Border From Wire
Is clear of obstacles.Is lower than lawn (OR of about the same height).(e.g. same level sidewalk, flowerbed)		Short Distance(30 cm / 12 inch)
Is an obstacleOr, is higher than the wire(e.g. wall, fence).		Long Distance(45 cm / 18 inch)

Area outside perimeter - same basic level and free of obstacles.

Short Distance

Area outside perimeter - has a wall as an obstacle.

Wall as air outlet Long Distance

2.2 Special cases of Perimeter Wire setup

2.2.1 Perimeter Islands

Continue uncoiling the wire, moving from the edge towards the obstacle. Apply RoboRuler's "Long Distance" to peg the Perimeter around the obstacle as shown in the drawing (clockwise direction).

Perimeter Wire position Perimeter Switch 2 wires under same peg Perimeter wire Direction of setup: clockwise around obstacle Min. distance between islands: 1.5 m (4.9 ft). Otherwise, demarcate jointly as one island.

Caution! Setting the Perimeter Wire counter-clockwise around the obstacle will cause Robomow to drive into the island.

○ Complete bordering the island and return to the spot that where you have left the lawn's edge.
The wires leading to the Island and returning from it should be parallel and touching. BUT DO NOT cross them!

○ Peg both wires, to and from the island, together with the same peg.

Robomow will not recognize these two wires. It will mow over them as if they do not exist. Robomow will recognize the single blocking wire around the Perimeter Island and will not enter this area.

If protected obstacles are grouped closely together, demarcate them by a single, continuous, Perimeter Island.

If obstacles are close to the edge, leave them out of the mowing area.

2.2.2 Narrow Passes

A narrow pass is part of the lawn which connects two larger zones. Following the Perimeter Wire, Robomow drives between these zones. But, it does not cross the pass while mowing each one of them.

Set the two wires parallel along the pass at a fixed distance of 30 cm (12 inches) between them (Marked on RoboRuler).

If the distance between the wires is smaller than that, the two areas should be set as 2 separate zones.

Diagram showing a palm tree with directional arrows and dashed lines on a green background, no text or symbols present.

Base Zone If wire lays near a wall or a fence, keep a distance of 65 cm (25") between wire and wall. Distance of 30 cm (12") between wires. Especially important near pass' entrances Base Zone Base Zone

2.2.3 A pond, swimming pool, or watercourse at lawn's edge OR:

Grass level more than 70 cm (2 ft) higher than outer area.

○ Set the Perimeter Wire at least 1.2 m (4 ft) from the water (or chasm).
- You may provide a fence or another barrier along the lawn's edge by the water, so Robomow will surely detect it.

The barrier should be at least 15 cm (6 inch) high. This will block Robomow, under all circumstances, from crossing over the Perimeter Wire into the water area.

If such a barrier exists, you may set the Perimeter Wire at the Long Distance of 45 cm (18 inches) from the barrier.

2.2.4 Slopes

Perimeter slope

☐ If a slope is steeper than 15 cm rise per 1 meter (0.5 ft rise per 3.3 ft), do NOT lay Perimeter Wire over it.

However, if there is a barrier (e.g. fence, wall, or hedge) that can protect the mower from sliding off, the Perimeter Wire can be set on that slope.

In-lawn slopes

○ Robomow can mow areas that have less than a 27% slope (roughly 27 cm per 1 meter / 0.9 ft rise per 3 ft).
Tip: If Robomow tilts off the ground while climbing a slope, it is too steep.

Exclude this steep area from Robomow's cutting area.

At least 1.2 m (4 ft)

At least 45 cm (18'')

1 meter (3.3 ft) Max 27% slope (15° degrees) 27 cm (0.9 ft)

2.3 Fastening Perimeter Wire to the Ground

It is not necessary to bury the perimeter wire, though you may do so, up to 10 cm (4 inches) deep.
Upon hammering the peg to its final depth in the ground, pull the wire tight.

Diagram illustrating a hand using a hammer to measure a tool applied to a soil or vegetation surface, with red arrows indicating the process.

WARNING!

Protect your eyes!

Protect your hands!

Use proper eye protection and wear appropriate work gloves when hammering the pegs. Hard or dry ground may cause pegs to break when driving them in.

Watering the lawn where the pegs are to be inserted can make your work safer.

Insert the pegs at distances that will keep the wire down below the grass level and prevent the wire from becoming a tripping hazard
☐ The wire and the pegs will soon become invisible under the growth of new grass.
☐ If additional wire is required in order to complete the setup, connect it using the water-proof wire connectors supplied with Robomow. (Refer to paragraph 10.7 – Splicing the Perimeter Wire).

IMPORTANT

Use only the wire connectors supplied with Robomow.

Neither Twisted cables, nor a screw terminal insulated with insulation tape are a satisfactory splice.

Soil moisture will cause such conductors to oxidize and which later leads to a broken circuit.

2.4 Back at Base Station – Completing the Perimeter Wire setup

Once the Perimeter Wire loop is completed and pegged to the ground, you complete the setup by attaching the beginning and end of the Perimeter Wire to the Base Station board.

Hold both ends of the Perimeter Wire: the wire that started the loop is the one with an attached connector.

○ Trim the end without the connector to make both of equal length. Remove any excess wire and Strip back 5 mm (0.2 inches) of insulation from the wire end.

- Peg the two perimeter wires down to the ground using the same peg leaving enough loose wire. Twist together the two loose parts.

○ Thread the two twisted wire ends through the center aperture in the Base Station.

Insert the end of the wire without the connector into the hole of the other wire's connector. Use a small flat screwdriver to tighten and secure this wire into the connector.

2.5 Assembling the Base Station

2.5.1 Laying and fastening power cord

Safety

Avoid injury!

The power cord should always be securely fastened to the ground! It should never present a tripping hazard.

The power cord should cross over soft surfaces ONLY.

It should NOT cross over hard surfaces (e.g. sidewalk, driveway) where it cannot be securely fastened.

2.6 Placing Base Station

Use RoboRuler to measure and place Base Station on the Perimeter Wire.

2.6.1 If Base Station is placed on the lawn – Internal Setup

○ Use RoboRuler to place the Base Station on the Perimeter.
If the area outside the perimeter is free of obstacles or if it is at the same relative height as the perimeter edge use the shorter distance of RoboRuler (30 cm/12 in)
If the area outside the perimeter is walled (building, fence etc.) or if it is NOT at the same relative height as the perimeter edge → use the longer distance of RoboRuler (45 cm/18 in).
○ Position the Base Station by the lawn's edge, with its fence facing the lawn.

Area outside perimeter: Same basic level and free of obstacles.

RoboRuler Short Distance Fence facing inside of lawn area

Area outside perimeter has a wall as an obstacle.

Fence facing inside of lawn area RoboRuler Long Distance

2.6.2 If Base Station is placed outside the lawn – External Setup

Place the Base Station, so that the distance between the Drive Wheel Supports and the Perimeter Wire inside the lawn is 45cm (18 inches). This is the longest dimension of RoboRuler.
○ Place the Base Station with a shift of 10-20 cm (4-8 inches) to the right.

The two wires are very close. This has an effect on the wire sensors readings. Therefore, the Base Station should be shifted.

The exact shift will be later adjusted during the final testing of the setup.

It is recommended to place the Base Station at least 30 cm (12 inches) before the end of the external pass.
This allows the mower a smooth entrance to the Base Station.
- Clear the pass of any obstacles. Verify that the pass is smooth, with no height differences, and its surface is firm.

Base Station placed in a right shift from the wire. 45 cm (18") – Long Distance of the RoboRuler 20 cm (8")

○ Create a "narrow pass" of wires, leading from the external Base Station to the lawn and back. The beginning (going) and the end (coming) sections of the Perimeter Wire create this pass.

2.7 Testing Base Station Setup

☐ Fasten the Base Station in place: Use a hammer to drive the 5 stakes in. start by placing the 2 rear stakes only part way into the ground.

Later, after testing for charging, some small adjustments may be needed. Then, you will hammer the 5 stakes all the way down.

○ Test as follows both Internal and External Base Station setups:

Connect the extension cord (15 m low voltage cable) to the Power Supply plug.
Connect the Power Supply to a regular household receptacle 230/120 Volts AC.

Note: The power supply is suitable for outdoor use, yet it is required placing it in a sheltered place, dry location, which is well ventilated and not exposed to direct sunlight.

A small flashing green light next to the 'ON' button indicates the system is on and functioning correctly.

The control panel has other indicators: a charging indicator and a "disconnected/broken Perimeter Wire" indicator.

The Base Station Board has an automatic shutoff feature, eliminating the need to turn it off after each use. It will shut itself off once the mower re-docks at the end of the operation.

2.8 Setup in Non-Base Zones

Non-Base Zone Only

A Non-Base Zone is a lawn or an area of a lawn, that is NOT connected to a Base Station.

A Perimeter Switch should be installed in these areas. Perimeter switch is an option in City 120.

When necessary, Perimeter Switch can be easily moved to other zones.

The Perimeter Switch MUST be Mounted vertically in order to maintain its' water resistance

Indoor Power Supply Zone A Wires leading from the perimeter to the Perimeter Switch are adjacent and touching.

2.8.1 Determining Perimeter Switch Location

Consider the following in order to install the Perimeter Switch at its optimal location:

○ Perimeter Switch is installed outside the perimeter of the Non-Base Zone.

○ Select an easily accessed spot.
○ Prefer a dry and sheltered location.
○ The Perimeter Switch is to be mounted vertically.

The vertical mounting maintains Perimeter Switch water resistance qualities.

The Perimeter Switch is supplied with an indoor power supply. Chose a location close to the electrical outlet.

2.9 Perimeter Switch placing options:

The Perimeter Switch connector is easily mounted and dismounted. This allows for quick switching from one zone to another.
- You may use the large stake attached to the back of The Perimeter Switch to easily insert it and pull it out of the ground.
☐ You may mount the Perimeter Switch on a vertical surface, such as a wall or deck railing. Use the three small bosses on the back of the switch cover.

2.10 Laying Out the Perimeter Wire

The perimeter wire setups in a Base and Non-Base Zone are almost identical.

Still, there are some special instructions for connecting Perimeter Switch to the Perimeter Wire.

At Perimeter Switch' location:

- Peg/fix the beginning section of wire near the Perimeter Switch.

■ Lay the Perimeter Wire from the Perimeter Switch to the lawn.

Remember to leave some loose wire at the beginning, in order to close the loop later.

■ Start laying the wire in a counterclockwise direction.

Plot Connector Counter-clockwise direction of wire layout

2.11 Completing and Testing the Setup

Once the Perimeter Wire loop is completed and pegged to the ground, you complete the setup by attaching the beginning and end of the Perimeter Wire to the Perimeter Switch.

At the end of the Perimeter Wire's loop, you have now two wires: one at the beginning and one at the end of the loop. Lay the two loose wires in the direction of the Perimeter Switch location and peg them to the ground using a single peg for both.

Completing Perimeter Wire at Perimeter Switch

2.12 At the Perimeter Switch's location:

○ Trim the ends of the loose wire (the one without the connector) to equal lengths and twist them together.
- Strip 5 mm (0.2 inches) of insulation from the wire that is not connected to the plot connector.
Insert this wire's end into the free hole in the connector and tighten the screws.
○ Plug the perimeter wire connector into the Perimeter Switch (see figure)

○ Press the ⏻ 'ON' button on the Perimeter Switch.

A small flashing green light next to the 'ON' button indicates the system is on and functioning correctly.

The control panel has other indicators: a disconnected/broken perimeter Wire and a poor splicing (connections) in the Perimeter Wire

the Robomow® ON button Flashing light indicates the system is on Indicates a disconnected/ broken wire Indicates a problem in splicing or a perimeter wire that is too long.

The Perimeter Switch has an automatic shutoff feature. There is no need to turn it off after each use. The Perimeter Switch will shut itself off after 12 hours of operation. You may manually turn it off by pressing the ⏻ 'ON' button and holding it for 3 seconds. Wait for a beep sound to indicate that the Perimeter Switch is off.

The Perimeter Switch can be operated by a rechargeable battery (available as an accessory).

Chapter 3 Preparing Robomow

Before using Robomow for the first time, you have to perform some simple preliminary settings. Once preparations are completed, your Robomow is set and ready to mow your lawn.

3.1 Inserting Power Pack Fuse

Your Robomow is shipped with the Power Pack fuse removed. The fuse is packed in a plastic bag attached to the top of the Power Pack.

○ Remove the fuse from the small plastic bag attached to the top of the Power Pack.
○ Remove the Power Pack from Robomow.
○ Insert the fuse into the fuse holder. The fuse can be inserted in either direction.
○ Carefully lower the Power Pack back into the Robomow

The Robomow now will power up (wake up). The Power Pack is charged at the factory and has plenty of power to perform the initial setup and test run.

☑ Important ☑ After the initial set-up process is completed the Power Pack needs to be charged for a full 20 hours before the first operation.

See Chapter 6, Charging

Insert the Power Pack fuse into the fuse holder. The fuse can be inserted in either direction

Remove the Power Pack from Robomow

3.2 Setting Country and first-time calibration

Robomow uses a sophisticated navigation system. An onboard compass-like device responds to earth' magnetic poles. In order to adjust to the variance in the magnetic North, it is necessary to calibrate Robomow to your geographic location.

This is a one-time procedure. It needs not be repeated unless the mower is moved several hundred kilometers away.

The calibration process is simple. Robomow will ask for it before the first time it is used in the automatic mode. It will lead you through the process.

○ Remove the Manual Controller from its holder and grasp it with both hands.

To remove Manual Controller: push it up with your finger inserted in the indentation to its left.

As a safety feature, Robomow operates manually only when the Manual Controller is removed from its holder.

Then, in order to return to Automatic mode, the Manual Controller has to be returned to its holder and adjusted until it is at level with top of Robomow.

Use the Navigation Button on Manual Controller to drive Robomow to an inner flat and smooth area of the lawn.

◆ Press the navigation button's arrows in order to drive to the desired direction.

☑ Important ☑ Forward and reverse directions correspond to your position when standing behind Robomow.

○ If the grass is extremely high, adjust the height and ground clearance of Robomow to their highest position.

○ Reinsert Manual Controller in its holder.

Adjust the controller and its coil until it is at level with top of Robomow.

○ In Base zone - confirm the Base Station is connected to the power. In Non-Base Zone, press the ⏻ ON button on the Perimeter Switch to activate the Perimeter Wire.

Press Robomow's GO button and go through the following steps:

If during the calibration process, a message is displayed when pressing the GO button, refer to the troubleshooting table of this manual (Chapter 10).

Such messages may be: "Check Signal", "Start Inside" or "No Wire signal"

Robomow will circle slowly throughout the calibration process.

Be patient until calibration is complete, it usually takes a few minutes.

For the duration of the process the display panel flashes a "wait" message.

Rarely, the first attempt to calibrate may fail. In such rare cases a "retry elsewhere" message is displayed. This usually is a result of interference such as nearby metal objects or even underground wires.

○ If a "retry elsewhere" message is displayed, move Robomow to another flat spot, at least 3 meters (10 feet) away and recalibrate.

Once the process is successful, no further interference can effect Robomow's calibration.

3.3 Setting The Cutting Height And Ground Clearance

Caution! Always remove the Power Pack before lifting mower off the ground or making any adjustments.

3.3.1 Setting cutting height

Low cut blades: 26 - 63 mm (1 - 2.5 inches)

Low cut using small wheels (not available in US): 20 - 57 mm (0.75 - 2.25 inch)

High cut blades (US customers): 38 - 89 mm (1.5 - 3.5 inch)

♦ Turn the front wheel hub clockwise (for lower cut) or counterclockwise (for higher cut). Each click represents 6 mm (1/4 inch) of cutting height. This raises or lowers the front wheel.

Warning

Severe injury hazard!

Never lift the mower or attempt to adjust the cutting height during operation. Blades are very sharp. They can cause severe cuts or lacerations.

When working around or near the blades always wear heavy gloves.

3.3.2 Setting rear ground clearance

○ Pull the height adjustment tab located in the Power Pack compartment.
- Slide the tab to its upper position – for low ground clearance. Slide the tab down – for high level of ground clearance.
○ If your Robomow has small wheels (not available in the US) the tab has an additional lower position.

It is recommended to set for maximum clearance – tab near base of Power Pack compartment. For European lawns and for lawns where grass is cut extremely low, less than 5 cm (2 inches): Setting to minimum level may work best.

Clockwise for lower cut Counterclockwise for higher cut

Rear ground height adjustment is located in the Power Pack compartment.

3.4 Testing Base Station and Perimeter Wire charging position

In order to ease adjusting Base Station's position, use just 2 stakes for the initial setting. After this test is completed, you will drive all 5 stakes in place.

○ Remove the Manual Controller from its holder and grasp it with both hands.
Use the Navigation Pad on Manual Controller to drive Robomow: position it on inner lawn, facing the Perimeter Wire, at least 3 m (10 feet) in front of Base Station,
○ Reinsert Manual Controller in its holder. Adjust the controller and its coil until it is at level with top of Robomow.

○ Verify that the section of the Perimeter Wire leading to the Base Station is pegged and secured to the ground. Correct pegging if necessary.

○ Verify that 'ON' led on the Base Station is blinking.
Press the upper scroll arrow on the Manual Controller once for the message 'Go to base' and then press GO.

○ Robomow starts moving towards Base Station.

Follow it and check if it docks properly into the Base Station: check that the two metal contacts on Robomow's front make full contact with the metal plate under the Base Station's cover.

If the plates are not in full contact, slightly move the Base Station, for Robomow to get into the right position for charging.

Once the test is completed, drive all 5 stakes into ground to fully secure the Base Station.

Scroll up once to until 'Go to Base' screen displayed

○ Walk along the side of Robomow while it is following the edge.

☐ If, at any point the mower is too close to outer object (e.g. walls, fences), or the bumper hits such objects, move the wire slightly towards the interior, away from the obstacle.

- Retest, until you are satisfied with the Perimeter Wire's layout.

Once complete, add pegs to all wire's sections that are above the level of grass tips or removed from ground level.

This is the time to inspect the whole wire installation for tripping hazard. Any raised or loose section of the wire should be tightened and pegged down with extra wire pegs.

If needed, purchase extra pegs.

Chapter 4 The mowing process – automatic and manual operation

4.1 For added safety:

○ Manual operation is disabled when the Manual Controller is in the holder.

◆ For manual operation: Remove Manual Controller from its holder.

○ Automatic operation is disabled when the Manual Controller removed from the holder.

For automatic operation reinsert Manual Controller in its holder.

Adjust the controller and its coil until it is at level with top of Robomow.

4.2 Driving Robomow – general instructions

Parts of the mowing process require driving Robomow to various locations in or out of the lawn.

○ Remove Manual Controller from its holder.

○ Hold the Manual Controller with both hands, with the STOP button side closer to you.

To maneuver Robomow, press the navigator pad in the direction you wish Robomow to move.

Driving Robomow with the navigator pad takes very little pressure. Press gently. Lightly roll your finger in the right direction.

4.3.2 Manual Manual depart

Manual depart is used when mowing the lawn at UNscheduled times, or when the lawn has to be cleared of people or debris before the scheduled mowing starts.

◆ To initiate manual start, press GO once.

If you prefer to skip edge mowing, press GO twice

If Entry Points have been previously set, Robomow will ask you to select a current entry point.

Robomow departs from Base Station and starts edge mowing: automatically completes one loop around the Perimeter Wire and reaches back to Base Station.

It will briefly start to dock, but then back up in order to mow the inner lawn.

Robomow automatically determines the entry point from the perimeter wire into the lawn. A 'Searching entry' message is displayed on the Manual Controller while it is searching for the entry point into the lawn.

4.4 Returning to Base Station

4.4.1 Auto Robomow automatically returns to Base Station at the end of mowing.

4.4.2 Manual Manual "Go to Base" option

You can manually send Robomow to Base Station anytime and from anywhere on the lawn.

◆ Manual Controller should be in its holder.
◆ Make sure Base Station is turned on.
◆ Point Robomow toward any Perimeter Wire section (but NOT a Perimeter Island or excluded obstacle).
◆ Perform the following sequence:

Once in the station, reinsert Manual Controller

Adjust the controller and its coil until it is at level with top of Robomow

○ Confirm the display changes to a battery charging icon, indicating a successful docking.

4.5 Activating the Perimeter Switch (Non-Base Zone)

Important! Mowing in Non-Base Zone requires a prior setting of each such zones.

If the zone to be mowed is not defined yet, do the setting now.

In order for Robomow to operate in a Non-Base Zone: the Perimeter Switch has to be turned on and the mower should be inside the active perimeter area.

○ Verify that a Perimeter Switch is connected to the zone to be mowed.
○ Press the ⏻ 'ON' button to turn on the Perimeter Switch.

A short beep sounds when the Perimeter Switch is turned on.

A green LED flashes to indicate proper operational state.

If one of the red LED indicators flashes, there may be some malfunction.

For more details, please refer to the troubleshooting guide (Chapter 8).

A "No Wire Signal" message on the Robomow's Display is an indication that Perimeter Switch is not turned on. Verify that you have properly connected the Switch to the Perimeter Wire, using the small green connector.

4.7 Edge Mowing (Non-Base Zone)

Robomow starts the mowing process by mowing the edges: along the Perimeter Wire. This creates a clean even cut around the perimeter. Edge mowing minimizes trimming along walls and other obstacles. Robomow will always mow the edge in a counter-clockwise direction. It will automatically find the edge (perimeter), mow it and then turn into the inner lawn area to complete the mowing.

○ Verify that the zone to be mowed is already defined in Robomow. If the zone is not set yet, do it now (see section 7.4, Work Time).
○ Reinsert Manual Controller in its holder. Adjust the controller and its coil until it is at level with top of Robomow.
○ Scroll down (using the DOWN arrow) to select the zone to be mowed and then press the GO once for Edge mowing.

4.8 Scanning (mowing)

Robomow mows your lawn in a systematic scanning motion until all grass is cut. It runs for the default "MAX" time, or for the amount of time previously set (See chapter 6, operator settings and advanced features). "MAX" is typically

2-3 hours of mowing, according to grass type and condition.

4.9 To skip Edge Mowing

If your lawn requires more than two operations per week, it is recommended to skip edge mowing at the additional operations.

○ Move Robomow to any point within the lawn which is at least 1 m (3 ft) from the Perimeter Wire.

Chapter 5 Setting the Weekly Program

5.1 Setting the weekly mowing program

Never let Robomow operate without supervision.

Serious injury can occur.

If the current date and time are not set correctly or are failed to be set when prompted, the times scheduled for automatic departure will not be correct.

Incorrect departure times can be dangerous if children, pets or bystanders are present in the mowing area.

For best cutting results, set the weekly program, so the Robomow and the sprinklers do NOT run at the same time.

Remove the Manual Controller from its holder.

• Follow the following steps to set the Robomow's weekly mowing program.
  Press the button at any time to return one step backward.

Note: This option is displayed only after 'Set entry points' is done (refer to 7.4.1). You can set specific entry point or to set 'Cyclic'. which means that the mower uses all entry points set cyclic mode.

◆ Press GO within the 10 seconds time limit to display a shortcut to the Weekly Program setting.

Incorrect departure times can be dangerous if children, pets or bystanders are present in the mowing area.

D	Skipped due to no contact with Base Station or due to no charging voltage.Power break or mower placed out of the Base Station at the scheduled depart time.
U	Skipped due to user choice.For example, user chose the ‘skip next depart’ option or set the ‘Auto depart’ to ‘off’.
C	Skipped due to no charging at the scheduled depart time, even though there was voltage.Typically, when Robomow is in Base Station, but the Manual Controller is not in its holder.
R	Skipped due to rainRobomow did not depart from the Docking Station at the scheduled time as it detected rain.
r	Docked before time due to rainRobomow did not complete its operation. It drove back to the Base Station as it detected rain while operating.

Chapter 6 Charging

Proper charging of the Power Pack is of utmost importance!

Failure to follow the charging guidelines will result in poor performance and a short Power Pack life.

Shock, injury, electrocution hazard!

Never use a Power Supply when the leads are damaged.

Use only the recommended Power Supply for your Robomow.

Do NOT pack the Power Supply inside a plastic bag, as it will over-heat.

Robomow will be automatically recharged at its Base Station at the end of all mowing sessions. It is best for the Power Pack to remain plugged in at all times of non-use, throughout the mowing season.

There is absolutely NO need for concern: no over-charging, no overheating and no damaging the Power Pack.

6.1 Charging at the Base Station

The Base Station is the primary Charging Station when Robomow is docking

When the Power Pack is being charged at the Base Station one of the following screens is displayed:

◆ If Robomow is docked and a Weekly Program is set:

◆ If Robomow is docked and a Weekly Program is NOT set. Or: if Auto Depart is turned off:

6.3 Power Management and Charging Alerts

6.3.1 The Power Pack should be fully charged before starting any operation.

○ Verify that the Power Pack is fully charged before operating it.

☐ Check for any excessive energy consumers like: dull blades, or heavy grass accumulation around the blades.

To even increase energy efficiency

6.3.2 Robomow operates under two run-time modes

Robomow's Power Management System helps protecting its battery.

○ Robomow should always be either charging or in operation.

If Robomow is neither charging nor operating, it will give a warning, reminding the user to charge it.

If Robomow is not connected to the charging outlet within a specific period of time, it will enter a "deep sleep" mode in order to conserve power.

In order to wake Robomow up from its deep sleep mode: remove the Power Pack for 10 seconds and then reinsert it.

6.4 Off-season storage

Preparing Robomow for off-season storage:

- Fully charge the Power Pack.

○ Remove Power Pack from Robomow and store it in a dry location at room temperature.

The Power Pack may be left in a garage or a shed if the temperature there will not drop below -20 °C (-4°F).

○ Recharge the Power Pack every three months while in storage.

☑ Important ☑ For further details of winter storage, please refer to section 10.9.

Set Default Edge

Use the Default Edge function to re-set edge mowing of a specific zone back to Robomow's defaults.

7.2.2

Child Guard

"Child Guard" is a safety feature that prevents young children or other unauthorized people from activating Robomow.

When Child Guard is set, Robomow will start operation ONLY after unlocking it.

IMPORTANT It Is strongly recommended to turn this feature on.

This will prevent children or anyone unfamiliar with the mower, form activating it.

To unlock Robomow's Child Guard:

◆ Press the arrow and then press the © key

7.2.3

Sound

Use the Sound option to turn all non-safety sounds off. This option still KEEPS all safety sounds on.

7.2.4

Wire position

Use the Wire Position option to test the Perimeter Wire's position at "Edge" mode, and wish to do that with the mowing motors switched off. This prevents damage to the Perimeter Wire after its initial setup has been completed.

7.2.5

Language

Use the Language option to view the display in other languages.

7.2.6

Scan Type

Use the Scan Type option when you wish the mower to move in a systematic parallel pattern. This type of mowing movement will replace Robomow's default Random operation with a systematic parallel motion, without using a compass (Wide Scan) or with a compass (Parallel). In Random movement (default), Robomow's movement pattern is irregular so it opens a different angle whenever reaching the perimeter wire or an obstacle.

IMPORTANT It is recommended to change the settings from the default of Random, only if the Robomow is not covering all sections of the intended area. If the Parallel option causes Robomow to drive back and forth in the same direction, with no progress, use either the Wide Scan or Random options.

7.2.7

Scan Width

Use the Scan Width option to change the mowing movement of Robomow. This can be beneficial in some lawns.

○ If the mower is continuously moving back and forth along the same path, it is recommended to increase scan width.

7.2.8

Enable Dock

Use the Enable Dock to switch ON the docking options menu of the Base Station.

If Enable Dock is turned off, the docking options menus are hidden.

7.2.9

Eco mode

Use ECO (Economic) option to operate Robomow with the minimum energy needed for cutting the grass and maintaining the lawn.

Operation in ECO mode reduces Robomow noise level during operation and allows longer operation periods.

As a default, the ECO mode is set 'On'.

ECO mode will turn 'Off' automatically, increasing the power of the mowing motors, for short periods of time, in areas or times when mowing of high and dense grass is detected. Robomow will revert back to ECO mode 'On' once this condition diminishes.

7.2.10

Signal Type

In some circumstances there may be interference to the wire signal caused by other wire signal activated in adjacent lawn (neighbor that use robotic lawnmower) or by any other appliance using similar frequency. In case of signal interference, you may see one of the following symptoms (usually close to the neighbor lawn):

a. Robomow is widely swinging when driving along the wire;

b. Robomow changes direction without reaching the wire;

c. Robomow crosses the wire outside the designated area;

d. 'Start inside' message is displayed although Robomow is inside the designated area and the perimeter wire is connected in the right polarity;

If your mower faced one of the above symptoms, to change the signal type call to service.

7.2.11

Blades replaced

Use the Blades Replaced option after having replaced the blades. This will restart the reminder counter, so it reminds you to replace the blades again after the next 200 hours of operation. (For details about replacing the blades, see 10.3).

7.2.12

Rain sensor

The Rain sensor feature enables Robomow to detect rain and to skip or stop the operation when rain is detected.

There are three options under the Rain sensor menu:

• Rain sensor on/off – to turn the rain sensor feature off, for Robomow to operate even in rain and in wet grass conditions.
  ○ Reading – to display the actual reading of the rain sensor.
  ○ Set sensitivity – to set the sensitivity of the rain sensor.

The default sensitivity is set on 9. This means that any reading below 9 will cause Robomow to detect rain and stop operating.

7.2.13

Anti-Theft

Use the anti-theft option to set a code that will have to be entered in order to activate Robomow.

You will be prompted to enter a four-digit code of your choice to use as your personal security code.

To change an existing password, you will first be prompted to enter your old password.

IMPORTANT Be sure to record your code for future reference.

You will find a place to record your personal security code in Chapter 9 of this manual.

Entry Points

Entry points are specific points on the perimeter, where Robomow leaves the edge and turns into the lawn to mow the inner area. Robomow is shipped with no 'entry points' set. For common shapes of lawns there is NO need to set specific entry points.

If your lawn shape is "special", you can turn the 'Entry Points' option ON. This will improve your mowed area coverage.

The Entry Points feature uses 3 default entry points: at the Base Station, at 30% and at 60% of the Perimeter Wires length. Robomow uses these 3 entry points in a cyclic order. You cannot set a specific entry point for a specific day.

If the default entry points are not suitable for your lawn, select the Set entry points option. This way, you are able to set alternative entry points and to appoint a scheduled day of your Weekly Program for each of these points.

Select the Entry points option to open this option and to scroll through the following sub-menus.

10.1 Recommended Maintenance Schedule

Maintenance Service Interval	Maintenance Procedure
Each Use	Check and remove grass clippings and dirt from the mowing deck if necessary, particularly when mowing wet and damp grass.Charge the Power Pack after every use.
50 Hours	Remove Power Pack and check for any damage on the blades.
150 – 200 Hours	Replace the blades.Replace more frequently if the edges are dull in rough or sandy conditions.IMPORTANT Remember to restart the automatic blades replacement reminder after every blades replacement.

10.2 Maintenance of the Mowing Deck

Robomow is a dedicated mulching mower. It may accumulate clippings under the mowing deck, particularly when mowing wet or damp grass.

Warning

Severe injury hazard!

Always remove the Power Pack before lifting the mower. Blades are very sharp. They can cause severe cuts or lacerations.

Always wear heavy work gloves when working with or around the blades.

NEVER, use a damaged or a broken blade. Use only sharp blades.

○ Inspect the underside of the mowing between operations. Clean if necessary.
○ Carefully scrape the collected grass debris from under the mowing deck.

Most grass accumulation can be removed using a small wooden stick or similar object.

You may remove the blades to gain better access to the mowing chambers.

10.3 Maintenance of the Blades

○ Examine the cutting blades for damage between operations.

○ Use only sharp blades. Replace any damaged blade.

○ Replace blades at least once per season, more often if they are severely dulled.

○ To remove the blades:

◆ Squeeze locking tabs on each side of blade retainer (1).

◆ Pull blade assembly off, away from mower (2, and 3).

When reinstalling the blade, line up the mating splines and push until a firm click is heard, indicating a proper seating of the blade onto the shaft (4).

10.5 Maintenance of the Power Pack

Always follow the maintenance and charging instructions for the Power Pack (see chapter 6).

10.6 Disposing the Old Battery Pack

IMPORTANT Do not place used batteries in your household trash. The battery must be collected, recycled, or disposed of in an environmentally sound manner. Return the old power pack to an approved sealed lead (acid) battery recycler.

10.7 Splicing the Perimeter Wire

If the perimeter wire needs to be spliced: Use the connectors supplied in Robomow's box. It is waterproof and gives a reliable electrical connection.

○ Strip 1cm (0.5 inch) of each wire end together

○ Twist the stripped ends together using pliers.

○ Insert the twisted wires into the splicing connector.

○ Screw the wire connector on the twisted wires; make sure it is tight.

IMPORTANT Neither Twisted cables, nor a screw terminal insulated with insulation tape are a satisfactory splice.

Soil moisture will cause such conductors to oxidize and which later leads to a broken circuit.

10.8 Maintenance of the Base Station area

Keep the Base Station entrance and area clean of leaves, sticks, twigs or any other debris that usually accumulate in such areas.
☐ NEVER spray a water hose directly on the Base Station. Always use a damp cloth and brush to clean the surface and area under the charging cover (where the contacts are).
○ Be careful when trimming around the Base Station with a powered weed trimmer as damage to the surface or power cord may occur.
○ Treat any insect mounds with a locally recommended insecticide.
☐ In the event of damage to any part of the power cord, stop use of the Base Station, disconnect the power supply and replace the power cord.

10.9 Winter Storage

10.9.1 Storing the Power Pack

• Fully charge the Power Pack.
  Separate the Power Pack from Robomow for storing.
  Store the Power Pack off the ground in a cool, dry place. Temperature should not be colder than -4 °F (-20 °C).
  ○ Charge the Power Pack before using the Robomow for the first time next season.
  It is recommended to fully charge the battery every three months while not in use.

10.9.2 Storing Robomow

○ Remove the Power Pack and clean Robomow
○ Store Robomow in a clean dry place. Cover it to keep it clean and protected.
Store Robomow standing on its wheels with a free space around the bumpers.

IMPORTANT Do not store Robomow on its bumpers. Make sure nothing else presses against the bumpers.

○ Check the condition of the blades. If necessary, replace the blades.

10.9.3 Storing the Perimeter Switch

○ Disconnect the Perimeter Switch, remove the batteries and store it in a dry place.

10.9.4 Storing the Base Station

It is recommended to remove the Base Station for the winter:

○ Disconnect the power supply from the power receptacle.
○ Disconnect the 15m extension cord from the Base Station Board.
○ Remove the extension cord and place it in dry place.
If it is not practical to remove the extension cord (15m cable): disconnect if from the board and protect it for the winter to prevent oxidation.
○ Unscrew the two screws holding the Base Station Cover.

○ Disconnect the green plot connector (between the perimeter wire and the Charging board).

○ Disconnect the green plot connector and place a water proof wire connector over the two free perimeter wire ends.

This prevents wire corrosion while not connected to the station.

○ Store all other parts in a dry place.

○ Getting ready for the new season

- Store all other parts in a dry place. - Getting ready for the new season

Before the new mowing season starts, lightly polish the charge contacts on the Robomow and the Base Station with a small piece of fine sandpaper, 200 grit or higher or with steel wool of '00' or higher grade.

This will remove any oxidation and allows optimal contact.

Before the first operation of the new season, reconnect Base Station setup (see chapter 2).

Chapter 12 Tips for maintaining your lawn

Robomow®- Lawn care has never been so easy

Best time to mow

Mow your lawn when the grass is dry. This prevents the clippings from clumping and leaving piles on the lawn. Mow it late in the day rather than during the heat of the day.

Mowing frequency

Mow often, producing short, small clippings. During the active growing season the mowing frequency should be increased to once every 3-5 days, before the grass is too long. Short clippings decompose quickly and will not cover the grass surface. If the grass gets too high, raise the cutting height, mow, then gradually lower it over several mowings.

Cutting Height

Follow the "1/3 rule:" mow no more than 1/3 of the length of the grass.

Proper mowing will produce short clippings that will not cover up the grass surface.

You may have to cut the lawn more frequently, or double cut, when the lawn is growing fast, such as in the spring.

1/3 2/3

Water

Grasscycling reduces the amount of water needed by lawns since the clippings are about 80 - 85% water. Grasscycling slows evaporation losses from the soil surface, and conserves water. Most lawns need less water when Grasscycling.

Watering

Water your lawn between 4 a.m. and 8 a.m. in the morning, so water has time to soak into the soil before the heat of the sun causes evaporation.

Your lawn needs 1 to 1-1/2" (3-4cm) of water weekly. Deep watering allows grass to develop a deep root system, enabling the lawn to resist disease and drought.

Do not over water

Too much water is not only wasteful but can also increase turf growth, which requires more frequent mowing. Let the soil partially dry out between watering. Water when the top two inches of soil have dried out. Use an object such as a screwdriver to probe your soil and measure the depth of the moisture.

Fertilization

Grasscycling reduces the amount of lawn fertilizer needed because the clippings provide about 1/4 of a lawn's annual needs.

Blades

Keep your mower blades sharp. Sharp blades provide a clean, safe and efficient cut. Dull mower blades will tear and shred the tips of the grass, which can provide an entry point for disease organisms and weaken the grass plant. It is recommended to replace all three Robomow blades once a year.

Thatch

Clippings and thatch are simply not connected. As mentioned previously, grass clippings are approximately 80-85 percent water with only small amounts of lignin, and decompose rapidly.

When we stop and think about it, golf courses, sports fields, and parks have been mowing grass for years and recycling with no grass catchers.

A small amount of thatch (approximately 1/2 inch) is actually beneficial to a lawn. Grass clippings protect your lawn's root system from heat and water loss.
