Sensors
Cleaning robot vacuum cleaners have dierent 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.

High-eciency lter
- The high-eciency lter is designed with bres that help trapping dust particles, 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 recommended to replace the lter 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 o. The high-eciency lter cannot be washed.
Mesh primary lter and sponge lter
