Roborock S8 PRO ULTRA brush for self-cleaning station

Suitable for the Ultra self-cleaning station for the S8 PRO ULTRA model: Designed to wash the cloth of a robotic vacuum cleaner. The brush rotates at 500 revolutions per minute and cleans the cloth deeply and efficiently, leaving it ready to be cleaned again.
Cleaning the self-cleaning station: As the brush cleans, it propels the dirty water at the base of the station towards the outlet, where it can be drawn into the dirty water tank. That way, nothing pollutes the area around the station.
Removable and washable: Since it is removable and washable, the brush can be easily maintained so that it is effective for a long time. For optimal performance, remove and empty the brush at least once every two months.
Compatible with Ultra self-cleaning device only.
In the package you receive 2 brushes.
