This compatible cleaning brush for robot vacuums (2 Packs) is engineered for Mop Washing: rotating at 500 RPM, the brush cleans the mop deeply and effectively, leaving it ready for the next 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. | | Only compatible with the Roborock S8 MaxV Ultra/S8 Max Ultra/S8 Pro Ultra/S7 Max Ultra/S7 MaxV Ultra robot vacuum and Empty Wash Fill Dock. | | What's inside: 2x Cleaning Brush. | |
