A brush roll is rotatably supported by bearings in a housing of a cleaning brush tool. One of the bearings is incorporated in a removable bearing arrangement that can be rotationally fastened and removed as needed on a cylindrical end of the housing. Preferably collar elements protruding cylindrically from the removable bearing arrangement form bayonet-type catch hooks that selectively engage with bayonet-type catch elements protruding radially outwardly from the cylindrical end sleeve of the housing. A detent on the housing engages a securing element on the removable bearing arrangement to secure the engaged bayonet-type fastening arrangement against rotational release thereof.
