ROBOROCK main brush gearbox for S6 Black MaxV robot vacuum, 9.01.0598

ROBOROCK 9.01.0598 — main brush gearbox for S6 Black MaxV robot vacuum; black, weighs 0.2 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.
