Match the complete roller assembly, including both end caps, bearing seats and the drive connection. A similar roller length or rubber color does not prove that it will seat in the cleaning head. Single rollers, bristle-and-beater pairs and dual rubber rollers use different decks. Check the manufacturer's supported-model list before transferring a roller between generations.
Remove hair and thread from the user-serviceable brush ends before deciding that the roller needs replacing. Follow the exact robot manual for opening the brush cover and refitting its latches. A brush obstruction error is a symptom: it can come from trapped debris, an incorrectly seated cover or a damaged assembly. It is not automatic proof that a new brush will fix the robot.
For an aftermarket listing, inspect the supplied components rather than only its photograph. Some packs include a roller without the end caps or bearing pieces shown in the original assembly.

Questions about Roborock S7
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.
