ROBOROCK main brush gearbox for robot vacuum (Q7 White and more), 9.01.1289

ROBOROCK 9.01.1289 — main brush gearbox for Q7 White, Q7 Black, Q7 White Max, Q7 Black Max robot vacuum; black, weighs 0.195 kg. The gearbox is what turns the main brush. When the drive wears, the brush stalls or binds, the robot reports a brush error, and a rattle starts coming from underneath. Before replacing anything, pull the brush and cut the hair wound around the bearings — that is the number one cause and it needs no parts at all.
