ABSTRACT:
A rotary brush sweeper includes a debris pan with an inlet portion that glides on a surface being cleaned. The debris pan automatically disengages from the sweeper upon being engaged by an obstacle in the path of the sweeper. The debris pan is configured with an inlet portion or scoop for directing debris propelled by a rotary brush into the debris pan. The scoop portion has a first upwardly and rearwardly inclined surface and a second surface beneath the first surface and facing downwardly. A low friction material covers the first and second surfaces of the scoop to facilitate collection of debris into the debris pan. The covering may include an integrally formed tip portion of abrasion-resistant material, and is preferably configured in cooperation with the scoop to mechanically grip onto the scoop without the need for screws or adhesives.
