Pääharja Roborock Saros Z70:lle (varaosaharja imurirobotille, MPN 8.02.0477)

Replacement main brush compatible with Roborock Saros Z70. This spare rotating brush is designed for the robot vacuum’s primary brush assembly to restore and maintain cleaning performance on hard floors and carpets. It removes hair, dust and debris from surface fibers and helps keep suction efficiency consistent as part of routine maintenance.

Advantages

The brush uses a combination of bristles and rubber blades to dislodge and channel dirt toward the suction inlet, reducing tangles and improving pickup on a variety of floor types. Regular replacement of the main brush helps maintain optimal cleaning results, reduces wear on the drive mechanism and prolongs the service life of the vacuum. The part is shaped to fit the main brush bay for straightforward installation and stable rotation during operation.

How to use

Turn off the robot and remove it from the charging base before replacing the main brush. Open the brush compartment, remove the old brush and clean the housing of accumulated lint and debris. Insert the replacement brush into the main brush slot, ensuring it seats securely and the end caps align with the mounting points. Close the compartment and run a short cleaning cycle to verify correct installation and smooth rotation.

Recommendations

Inspect and clean the main brush every 1–2 weeks depending on usage and household conditions. Replace the brush when bristles are visibly worn, rubber blades are damaged, or cleaning performance declines. Keep the brush free from long hair wraps and fibers to maintain optimal suction and reduce motor strain.
