5. CLEANING AND MAINTENANCE

High-efficiency filter. Fig. 8.

• The high-efficiency filter is designed with fibres that help trap dust particles, dust mites, pollen, etc. It is very important to periodically clean the filter, to prevent these particles from building up in the filter, causing efficiency loss. It is convenient to carry out this maintenance once a week.
• It is recommended to replace the high-efficiency filter with a new one without exceeding 160 cleaning hours.

Recommendation

You can remove dirt from the high-efficiency filter with a small brush or gently shake the filter on a hard surface to remove the dust. The high-efficiency filter cannot be washed.

Primary mesh filter and sponge filter. Fig. 8.

The filtering system is featured with a primary mesh filter and a sponge filter, located next to

ENGLISH

the high-efficiency filter. It is suggested to replace them either after a maximum of 160 hours of use or when they are worn out due to operation.

Recommendation

Dirt can be removed with a small brush or by shaking carefully against a hard surface for dust to fall off. You can also use warm water without detergents to obtain better results. Always make sure they are completely dry before installing them again; otherwise, moisture can reach the robot vacuum cleaner's motor and damage it.

Cleaning the free-fall sensors

Use a clean, dry, and soft cloth to wipe off any dust from the fall-detection sensors located on the robot vacuum cleaner's lower part.

Warning:

Do not apply cleaning products directly on the sensors.

Cleaning the main brush. Fig. 9.

The main brush rotates at high speed and helps pushing the dirt into the suction mouth. This brush is in contact with the floor, and therefore with dirt, so it can wear out overtime, negatively affecting cleaning efficiency. For this reason, it is suggested to replace the main brush after a maximum of 320 hours or less.

1. Slightly press the main brush frame's tabs to open the main brush compartment and remove it.
2. Remove hair, lint, and other dirt trapped in the brush and around the shafts with the help of the self-cleaning brush.
3. Clear and clean the robot vacuum cleaner's suction channel.
4. Reinstall the main brush and its frame.

Tip

It is recommended to clean the main brush once a week with the help of the self-cleaning brush.

Side brushes. Fig. 10.

Side brushes are designed with multiple bristles and are used to push dirt towards the suction mouth and to thoroughly clean edges and corners. These brushes can wear out over time, negatively affecting cleaning efficiency. For this reason, it is suggested to replace each side brush after a maximum of 220 hours or less.

Tip

It is recommended to clean the side brushes once a week with the help of the self-cleaning brush.

Sensors

• The robot vacuum cleaner has different types of sensors, for example, proximity sensors that allow the robot to move around while detecting obstacles, or fall-detection sensors that help the robot detect slopes or possible gaps/unevenness such as staircases. These sensors are always in contact with dust particles, and therefore can deteriorate over time, causing possible navigation errors.
• It is suggested to clean all the robot sensors with a dry and soft cloth after a maximum of 35 hours of operation or less.

Charging and replacing the battery

• To lengthen the battery shelf life, leave the robot vacuum cleaner to charge in the charging base when not in use.
• Remove the battery and store it in a safe, dry place if the robot vacuum cleaner will not be used for a long period of time.

Follow the below instructions to replace the batteries: Fig. 11:

1. Unscrew the screws on the battery compartment, remove the battery cover, and the battery itself.
2. Insert the new battery with the battery label facing up.
3. Put the battery and the battery-compartment cover back in place and properly fix the screws again.
