Abstract
A street sweeper system is used typically in a motorized vehicle. The sweeper utilizes a cylindrical brush rotating about an axis generally perpendicular to the vehicle's direction of motion. A conveyor belt catches debris thrown forwards and upward by the brush and moves the debris to a hopper. A cutoff flap is mounted contacting a front portion of the brush. The cutoff flap deflects debris that moves upwards along a front portion of the brush back downwards to be recollected at the conveyor.
