The Roborock S7 Pro Ultra sits at the top of the S7 series, pairing the platform’s sonic mopping and high-power suction with a RockDock Ultra that handles self-emptying, water management, and mop maintenance without user input. At this level of the lineup, the expectation is a robot that runs at full capability every time the dock sends it out, and meeting that expectation requires the main brush to be in the condition it was when new. The rubber brush compound flexes thousands of times per cleaning session. Over months of use, that cumulative flex gradually changes the geometry of the fins, reducing floor contact and narrowing the suction channel in ways that are not visible but are measurable in pick-up quality across both hard floors and carpet.
This is where replacing on schedule matters. This set contains Plus.Parts® components designed as a direct-fit alternative to the original S7 Pro Ultra brush: 3 washable rubber main brushes that match the roller bay exactly and install via the same tool-free clip as the factory part. The rubber compound is selected for performance across the full replacement cycle, not just break-in sessions, maintaining the floor-contact geometry that the S7 Pro Ultra’s suction is calibrated around.
The S7 Pro Ultra is built to perform. These brushes are built to keep it that way. Reach out to our team with any question about compatibility, the full S7 Pro Ultra range, or your order; we respond personally.
