4. INSTALLATION

Robot and charging base installation

Fig. 6.

Connect the charging base to a power supply and store the remaining cable. It is important to store the remaining cable at the bottom of the charging base to avoid it from being dragged and disconnected.

Place the charging base against the wall, leaving the safety distance indicated in the below picture.

Note: Ensure a space of at least 1 m on both the left and right side of the charging base, and a space of at least 2 m in front of it.

Fig. 7.

Warning: Do not expose the charging base to direct sun light.

Long press the power button for 3 seconds; when the light indicator turns on, place the robot on the charging base.

Fig. 8.

Steady blue light: ON/operating

Oscillating orange light: Charging

Red light blinks: Error

Notes:

Take the robot to the charging base if the battery is low. The robot might not turn on if the

battery is very low.

The robot will automatically turn on when placed on the charging base.

The robot cannot be turned off during charging.

Wet & dry and dust tank installation

Fig. 9.

Recommendation: It is not suggested to use the scrubbing function for the first-time use.

1. Open the tank's blue silicone lid, fill the tank with water carefully so water does not come out and close it again. Make sure the silicone clip is properly closed to avoid water from pilling. Fig. 10.

2. Install the tank in the robot following the indicated direction. Make sure the clip is properly fastened.

3. Only for Wet & dry tank installation:

Attach the mop to the bottom part of the mop bracket with the Velcro.

1. Manually press the clips on both sides of the Wet & dry tank and push it into its correct position. You will hear a click when it is properly fixed.

Fig. 11.

Recommendations:

Do not use the scrubbing function while the robot is unattended.

Remove the Wet & dry tank when the robot is charging or not in use.

If there are carpets in the house, set Restricted Areas to avoid the robot from passing over them.

Add some drops of cleaning agent (not corrosive) if considered necessary.

To remove the mop bracket, press the release button and pull from it outwards.

Warnings:

Using cleaning agents in excess might block water outlets.

In order to achieve perfect scrubbing, it is suggested to moisten the mop before using it.

First cleaning

Once the robot and the charging base are completely installed, follow these steps before scheduling the first cleaning cycle.

First of all, the robot must be fully charged. It is suggested to allow the robot to charge overnight. When it is fully charged, it may carry out the first cleaning cycle and save the first map. To do so, activate Auto cleaning mode and Eco power level. It is very important to follow these indications for the robot to recognize each and every corner in the house and to create a complete map.

If the house where the robot is going to be used is too big and the robot runs out of battery, do not worry. The robot features TotalSurface 2.0 technology, so when it returns to the charging base, it saves the full map and those that have not been completed. Once it is charged again, it resumes the cleaning cycle from the point it has stopped until it maps the whole surface.

ENGLISH

The robot keeps on mapping constantly, therefore it adapts independently to each house's features and continuously improves previous maps.

5. OPERATION

Once the robot's light indicator changes from oscillating orange to steady blue, the battery is fully charged and the robot is ready to operate.

The robot cannot operate with low battery.

Recommendations: Remove all cables and obstacles from the floor before operating the robot in order to avoid accidents and damage.

5.1. Robot buttons

Fig. 12.

Auto mode

Press the power button on the robot for it to start cleaning automatically, first a cleaning cycle in Edge mode and then another cycle in and organized zigzag motion, recognizing which areas it has cleaned and which ones it has not. The robot will automatically plan the cleaning route as it is cleaning. If during this mode the robot is controlled manually, the robot will calculate the route again and could go through previously cleaned areas. In order to ensure efficient cleaning, do not operate it manually during auto mode cleaning.

Thanks to its Total Surface 2.0 technology, if the battery is low during the cleaning cycle, the robot will smartly return to the charging base automatically and, once it is fully charged, it will resume the cleaning process from the same point, offering a high-efficiency cleaning.

During cleaning, the robot will stop briefly to evaluate the area and calculate the cleaning route (this stop will vary depending on the house conditions).

Note: The robot cleans in an organized way and per 4x4 m squared areas, therefore it might leave the room where it is cleaning to finish off the delimited area. Do not worry, the robot will clean all the accessible surface.

Back home mode

Press the back home button on the robot in order to send it to the charging base. This mode can be activated during any other cleaning cycle and the robot will stop cleaning and return to the charging automatically.

The robot will take the shortest route back to the charging base thanks to its map memorizing and the smart back home function. When a cleaning cycle has been completed or the robot's battery is low, the robot will also return to the charging base to avoid running out of battery.

Recommendation: Remove the Wet & dry tank during charging.
