1. A rotary brush sweeper for removing debris from a surface, comprising:
- a housing having front and rear portions with respect to movement of the sweeper;
a brush rotatably supported by the housing;
drive means for rotating the brush;
a debris pan situated rearwardly of the brush for collection of debris swept thereinto by the brush;
pan support means for supporting the debris pan relative to the housing but for releasing the debris pan upon rearward pressure on the debris pan;

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. Rotary brooms may be attached to the left and right front sides of the sweeper. The support structure for the front wheel provides broom-to-ground height adjustment for the side brooms. Additionally, brush-to-ground height adjustment is obtained through a support structure for the front wheel. The axle of the rotary brush is held in place under the tension of a drive belt for the rotary brush.
