Side brushes
Side brushes are designed with multiple bristles and are used to push dirt towards the suction
nozzle and to clean thoroughly edges and corners. These brushes can wear out over time,
aecting negatively to the cleaning eciency. For this reason, it is suggested to replace each
side brush after a maximum of 220 hours.
Recommendation
It is recommended to clean the side brushes once a week with the help of the cleaning brush.
Main brush
The main brush is designed with bristles and silicone, spins at top speed and helps introduce
dirt into the suction nozzle. This brush is in contact with the oor, and therefore with dirt, so it
can be worn out over time, aecting negatively to the cleaning eciency. For this reason, it is
suggested to replace each side brush after a maximum of 320 hours.
Recommendation
It is recommended to clean the main brush once a week with the help of the cleaning brush.
Sensors
Cleaning robot vacuum cleaners have dierent types of sensors, for example, proximity
sensors that allow the robot to move around while detecting obstacles or free-fall 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 be blocked over time,
causing possible navigation errors. It is suggested to clean all the robot’s sensors with the
cleaning brush or with a dry cloth after a maximum of 35 hours of operation.
Battery charge and replacement
- To lengthen the battery’s service life, keep the robot charging on the charging base when
not in use.
- If the robot is not going to be used for a long time, remove the battery from the product and
store it in a dry and safe place.
- To replace the battery, follow the instructions below:
- Unscrew the 2 screws on the battery compartment, remove the battery cover and the
battery. Fig. 39
- Insert the new battery with the battery label facing up. Fig. 40
- Place the battery and the battery cover in its place and x properly the screws back again.
