How to use

Power off the robot vacuum and, if applicable, remove the battery or place the unit on its charging dock to prevent accidental activation.

Ensure the roller is seated correctly and that end caps or bearings are engaged. Reattach any covers and perform a brief test run to confirm normal rotation and contact with the floor.

Usage recommendations

Inspect the brush roller regularly for hair tangles, trapped debris or excessive wear. Clean the roller and end bearings periodically to prolong service life. Replace the roller when filaments are flattened, rubber elements are damaged, or the part causes reduced cleaning performance. Use genuine-fit replacement rollers to maintain balanced rotation and avoid potential damage to the robot's brush motor or brush housing.
