Main Brush Roller for Xiaomi Roborock S55 S5 S6 Max MaxV Mija S1 by JETtools SB9599

This Main Brush Roller by JETtools is a direct-fit replacement designed for use in compatible Xiaomi Roborock robotic vacuum models including S55, S5, S6, Max, MaxV and Mija S1. The rotating brush assembly restores the vacuum’s ability to lift dust, pet hair and small debris from both hard floors and low- to medium-pile carpets. The part is intended for routine maintenance and for returning cleaning performance to factory levels when the original roller shows wear or damage.

Advantages

The brush roller features a balanced combination of bristles and flexible blades to dislodge dirt while minimising tangling. Constructed to match the original geometry and rotation profile, it helps maintain optimal suction and sweep efficiency. Using a purpose-made replacement brush reduces the risk of uneven wear on drive components and ensures consistent cleaning contact across different floor surfaces.

How to use

Power off and, if applicable, remove the battery or place the robot on a powered-off dock before replacing the brush. Access the main brush compartment by removing the underside cover or brush guard as specified in the robot’s user manual. Pull out the worn roller, clean the brush housing and bearings of accumulated hair and debris, then insert the replacement roller making sure it is seated and aligned with the drive fittings. Reattach the cover and test the device briefly to confirm proper rotation and clearance.

Usage recommendations

For consistent cleaning results, inspect the main brush every 1–3 months depending on usage and pet hair load. Remove hair wraps from the bristles and bearings to prevent motor strain. Replace the roller if bristles are flattened, blades are torn, or if brush rotation becomes irregular despite cleaning.
