How to use

Place the charging base against a wall on a flat surface and charge the robot before first use. Fill the water tank if you plan to use the wet mopping function and select the desired water output level. Use the Xiaomi Home app to set up Wi‑Fi, create a map, select cleaning zones or schedules, and choose one of the four suction modes according to floor type and dirt level. The robot will perform 360° scanning to build a map and then follow the planned path. After cleaning, it will automatically return to the charging base.

Recommendations

Keep cables, small objects and loose rugs cleared from the floor before operation. For best mopping results, use the recommended water level for your floor type and empty the dust container and rinse the water tank regularly. Place the charging base in an open area to ensure reliable docking and charging.
