Main brush cleaning
-
Slightly press the main brush frame's tabs in order to open the main brush storage
compartment and to remove it. Fig. 43
-
Remove any hair, fluffs or dust collected in the brush and around the axes. Fig. 44
-
Clear and clean the robot's suction channel. Fig. 45
-
Reinstall the main brush and its frame. Fig. 46
High-efficiency filter
-
The high-efficiency filter is designed with fibres that help trapping dust particles, dust
mites, pollen... It is very important to clean periodically the filter, to avoid 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 filter with a new one without exceeding 160 cleaning
hours.
Recommendation
Dust can be removed with a small brush or by shaking it carefully against a hard surface for
dust to fall off. The high-efficiency filter cannot be washed.
Mesh primary filter and sponge filter
The filtering system is featured with a mesh primary filter and a sponge 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
Dust can be removed with a small brush or by shaking it carefully against a hard surface for
dust to fall off. You can also use warm water without detergents to get a better result. Make
sure they are completely dry before placing them.
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, affecting negatively to the cleaning efficiency. 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 floor, and therefore with dirt, so

it can be worn out over time, affecting negatively to the cleaning efficiency. 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 different 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. 47
-
Insert the new battery with the battery label facing up. Fig. 48
-
Place the battery and the battery cover in its place and fix properly the screws back again.

Solution
Place the robot on a stable surface
and restart it. Do not move it.
Check the bumper and remove any
object that may be blocking it.
Check if the bumper is dirty and clean
the sensor.
The robot has run out of battery and
you need to manually place it on the
charging base.
