The attachment point matters more than the number of arms. Check whether the brush uses a screw or a push-fit hub, the shape of its center and the manufacturer's part identifier. Three-arm and five-arm brushes can look interchangeable while belonging to different drive modules. Keep any module-version caveat on the official listing with the fit decision.
With the robot powered down, inspect the user-removable brush for wrapped hair, damaged arms and a cracked hub. Use the removal method in the model manual. A push-fit brush must seat normally; a screw-fit brush should not require a substituted screw or extra force. A brush that still stalls after cleaning needs further manufacturer diagnosis rather than repeated replacement purchases.
An aftermarket seller may describe a longer bristle or softer material as an upgrade. Those descriptions do not establish fit or measured cleaning performance.

Questions about Roborock S5 Max
Does a listed original part verify an aftermarket pack?
No. Match that pack separately. The original identifier, source market and any model suffix must agree, and seller-only wording remains unverified.
Why can the page show an excluded or unverified item?
Those records explain a known mismatch or an evidence gap. They help prevent an incorrect purchase; neither state has a shopping button.
