Roborock G20S Ultra – Plus.Parts® Replacement Brush Set

The Roborock G20S Ultra is a high-performance Roborock robot vacuum built for thorough, consistent coverage across both hard floors and carpeted areas. As with all Roborock’s advanced range, the cleaning system depends on two brush types working in coordination: the rubber main brush, which rotates against the floor to agitate and channel debris into the suction inlet, and the side brushes, which extend the robot’s reach into corners and along skirting boards where the main brush cannot arrive unaided. Both wear on a cycle tied to how much the robot runs. The side brushes lose their outward flex first, reducing edge-coverage width before the bristles visibly shorten. The main brush compound stiffens more gradually but has a more direct effect on overall pickup: a worn rubber roller moves less debris per pass, and suction alone cannot compensate for the agitation gap.

This set contains Plus.Parts® brush components built as direct-fit replacements for the Roborock G20S Ultra: two anti-tangle rubber main brushes and four anti-tangle side brushes. Together they cover two full service intervals for the main brush and four for the side brushes, so both replacement schedules are sorted in a single order. The main brushes are dimensioned to the G20S Ultra’s housing and use the same clip-fit installation as the original Roborock components. The rubber compound is formulated to maintain its agitation contribution across the full replacement cycle; the side brush arms are made from flexible material that holds its outward reach rather than collapsing early.
