This compatible cleaning brush for robot vacuums is engineered for Mop Washing: rotating at 500 RPM, the brush cleans the mop deeply and effectively, leaving it ready for cleanup. Dock Cleaning: As the robot vacuum brush cleans, it drives dirty water in the dock's base towards the outlet, where it can be drawn away into the dirty water tank, ensuring a thorough and mess-free cleaning process. Detachable & Washable: As it is removable and washable, the brush can be easily maintained, keeping it effective for longer. For optimum performance, remove and wash the brush once every two months.
