Schedule cleaning runs or start the robot manually according to your needs. For effective cleaning, clear loose cables and small objects from floors and ensure thresholds and rugs are suitable for robot navigation.

Usage recommendations

Use the wet mopping function on sealed hard floors and avoid excessive moisture on delicate surfaces. Empty the bagless dust container and rinse the water tank regularly to maintain cleaning performance. For homes with many obstacles, run an initial mapping or manual supervision to confirm optimal routes.
