Bearing arrangement of a rotating brush roller

摘要

A rotating brush roller for a floor cleaning device has its ends supported via a bearing in a support arrangement of a brush housing. A brush strip is received in a spiral groove in an outer circumferential surface of the brush roller. The support arrangement includes a stationary cover and defines an access opening. A removable cover is releasably secured to the brush housing by a catch element, and selectively covers or uncovers the access opening, allowing access to the brush strip at an end of the spiral groove. A first deflector element on the stationary cover and a second deflector element on the removable cover together form a thread deflector that cooperates with a counter element on the end of the brush roller.
