With the Dreame Dweilborstel RMP13, your robot vacuum will get your floors truly clean again. This mop brush replaces the old mop roller of your robot vacuum. During mopping, the self-cleaning mop roller stays wet with clean water and picks up dirt right away. This way, your floor stays clean and streak-free. If you replace the brush on time, you'll prevent bad odors. The cleaning performance also stays strong. Replace the brush about once every 3 to 6 months. How often you do this depends on how often you use the robot vacuum. The brush works on all hard floors. In the cleaning station, the mop automatically rinses and dries after each use. This saves you time and effort. You can use the replacement mop roller with the Dreame Aqua 10 Ultra Roller Complete and Aqua 10 Roller.
