Roborock Saros 20 Sonic – Plus.Parts® Brush Care Kit

The Roborock Saros 20 Sonic builds on the Saros 20 platform by adding sonic-vibration mopping alongside the vacuum cycle. The vibration system agitates the mop pad against the floor at high speed, lifting dried deposits that a static pad would drag over rather than remove. That combination of vacuuming and sonic scrubbing means the robot runs harder cycles than a vacuum-only machine, putting more thermal load and mechanical stress through the brush components in the process. The anti-tangle main brush handles the suction side of each pass, and the side brushes keep the debris field directed inward from walls and corners. Under daily use, the rubber compound in the main brush loses the elasticity that keeps it in tight floor contact, and the side brush tines migrate outward until the inward-directing angle flattens and debris near walls passes under the robot rather than being swept toward the roller.

This brush care kit contains two replacement anti-tangle main brushes and four replacement side brushes, all manufactured using Plus.Parts® components as a direct-fit replacement for the original Roborock Saros 20 Sonic parts. The fit is precise and the installation tool-free; each component mounts into the robot’s existing housing without adjustment. Replacing the main brush brings back the floor-contact efficiency that a stiff brush loses, and fresh side brushes restore the edge-coverage geometry the Saros 20 Sonic is built around.

These parts maintain their mechanical properties across the full replacement interval. For questions about this order or compatibility with your exact Saros 20 Sonic variant, get in touch; the team will answer personally.
