Floor sweeping apparatus (9) of the type having a rotary brush member (20), which in use is driven to rotate about a generally horizontal axis, the brus h member (20) having bristle elements (22) that, as the brush member (20) rotates, extend during part of their range of movement through an aperture (13) in a base plate (12) of a housing (10) in which the rotary brush member (20) is rotatably journalled has at least one bristle element (22), hereinafter called an end-most bristle element (25), arranged immediately adjacent to each end of said brush member (20), and a deflector member (26) is provided at each end of the aperture (13) to co-operate with said end-most bristle element (25) at the respective end of the brush member (20). 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.
