ABSTRACT:
A sweeper movable over a surface to be swept includes a frame having a longitudinal axis parallel to the direction of sweeper movement and a debris hopper mounted on a front portion of the frame. There is an opening in the rear of the debris hopper to admit debris. A first brush rotates about an axis transverse to the longitudinal axis of the frame and is located behind the debris hopper and has a motor for rotating the brush to throw surface debris forward into the hopper. There is a second brush which is also rotatable on an axis transverse to the longitudinal axis of the frame, with the second brush being positioned away from the surface to be swept and in front of the first brush. There is an auxiliary sweeping lip positioned closely adjacent to the second brush, which lip and the second brush add momentum to debris swept by the main brush into the hopper, so that the hopper is more fully loaded. The improvement is especially notable when sweeping light debris such as crumpled paper, leaves, etc.
