Roborock’s approach to the main brush across the Q and S series prioritises low-maintenance performance: the rubber roll picks up without collecting hair tangles, and the tap-clean design means brush maintenance takes seconds rather than minutes. The Roborock models using the R100042 brush specification benefit from that low-friction pickup on hard floors and solid debris collection on carpet where brush conformance matters most. What changes over time is the rubber’s ability to maintain that conformance: a fresh brush flexes into floor texture variation; an ageing one sits flatter, leaving a gap between the pickup edge and the actual floor surface.
This set contains Plus.Parts® rubber main brushes for Roborock devices matched to the R100042 specification: a pack of 4 brushes covering two consecutive replacement intervals. The clip-fit mount matches the original dimensions for straightforward installation. The compound in these brushes is designed to retain its conformance and flexibility across the full service window, meaning the performance benefit of a fresh swap lasts the length of the intended replacement interval rather than fading within the first month.
