ABSTRACT:
A surface maintenance apparatus is described, having a sweeping system positioned near the front or leading edge of the apparatus. The sweeping system includes a plurality of brushes and a removable hopper for collecting debris. The sweeping system is capable of being raised off the surface being maintained when the sweeping system encounters an obstacle or irregularity on the surface. The brushes are pivotally mounted to the surface maintenance apparatus to allow the brushes to be rotated away from each other, providing access to the removable hopper from the front end of the surface maintenance apparatus.
