Roborock Main Brush Gearbox Black for S8 Pro Ultra

The main brush gearbox is the drive component that keeps your Roborock S8 Pro Ultra running smoothly. When your robot's brush starts to slow down or stop spinning, a worn gearbox is often the culprit—replacing it restores full cleaning power at a great price point compared to a full brush assembly.
