Across Roborock’s Q and S series, the rubber main brush is what converts high suction into effective floor coverage on a daily basis. On hard floors it channels debris into the intake rather than scattering it; on carpet it agitates deep-pile debris loose where weaker floor contact would leave it behind. The Roborock robots using the R100045 brush specification depend on that dual-surface capability for the all-home cleaning performance that makes them practical daily-use robots. The rubber compound that provides that capability has a working life: daily use, particularly on abrasive surfaces or in households with fine grit from outdoor tracking, accelerates the hardening process and shortens the window of peak performance.
This set provides Plus.Parts® rubber main brushes for Roborock devices using the R100045 brush specification: 4 brushes in total, providing two full replacement sets in one order. The fit is direct, matching the original clip mount and roller dimensions for a straightforward swap. The compound is chosen for durability across the recommended interval, resisting the early stiffening common to cheaper alternatives and maintaining surface conformance further into the service life of the brush.
The support team behind every order is reachable for questions about compatibility, delivery, or anything else. Real people, personal answers, promptly delivered.
