ABSTRACT:
A floor sweeper is provided. The sweeper includes a frame having a corner portion. A hub member is mounted at the corner portion for rotation about an upright axis which is inclined to the horizontal. The hub has a circumferential side face and an underside with faces toward a surface to be swept. An annulus of bristles projects from the sideface of the hub member. The bristles have free end portions projecting downwardly beyond the underside so that increments of the annulus consecutively contact the surface to be swept because of the inclination of the axis. An annulus of radially extending teeth are connected to the underside of the hub member from which they extend downwardly to thereby engage the surface to be swept so as to rotate the hub member.
