High-eciency lter
The high-eciency lter is designed with bres that help trapping dust par-
ticles, dust mites, pollen... It is very important to clean periodically the lter,
to avoid these particles from building up in the lter, causing eciency loss.
It is convenient to carry out this maintenance once a week.
It is suggested to replace the lter by a new one after a maximum of 160
hours of use.
Recommendations: Dirt can be removed with a small brush or by shaking it
carefully against a hard surface for dust to fall o. The high-eciency lter
cannot be washed.
Mesh primary lter and sponge lter
The ltering system is featured with a mesh primary lter and a sponge
lter. It is suggested to replace them either after a maximum of 160 hours
of use or when they are worn out due to operation.
Recommendations: Dirt can be removed with a small brush or by shaking it
carefully against a hard surface for dust to fall o. You can also use warm
water without detergents to obtain better results. Always make sure they
are completely dry before installing them again.
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, aecting negatively to the cleaning
eciency. For this reason, it is suggested to replace each side brush after a
maximum of 220 hours.
Recommendations: 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 introducing 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, af-
fecting negatively to the cleaning eciency. For this reason, it is suggested
to replace each side brush after a maximum of 320 hours.
Recommendations: It is recommended to clean the main brush once a week
with the help of the cleaning brush.
Sensors
Cleaning robot vacuum cleaners have dierent types of sensors, for exam-
ple, proximity sensors that allow the robot to move around while detecting
obstacles or free-fall sensors that help the robot to detect slopes or possi-
