The deflector members (26) deflect said end-most bristle elements (25) axially beyond the end of the aperture (13) as said end-most bristle elements (25) extend through the aperture (13) during the rotation of the brush member (20) to effectively extend the sweeping action at least up to, and preferably beyond, the outer edge of the housing.
