ABSTRACT:
A floorcare device has a round brush located in a housing and rotatable about a rigid axle. At least one axial end portion of the axle is supported in the housing by an eccentric, so that by turning the eccentric the height of the axle and thereby of the round brush relative to the housing can be varied. Turning of the eccentric is performed by a ratchet mechanism. Another such eccentric may support the other end of the axle. The ratchet mechanism may include two ratchet wheels each provided on a respective one of the eccentrics, and two rings surrounding the ratchet wheels and having inner ratchets engageable with the latter.
