Abstract
A cleaning element, particularly a brush for incorporation in a vacuum cleaner nozzle, has a shaft with bristles which shaft has its ends journalled in the housing of a cleaning implement by means of bearings and shock absorbers. In order to give a compact construction and to reduce the spacing between the ends of the shaft and the side walls of the implement housing, the bearings with bearing housings project into openings in the ends of the shaft.
