ABSTRACT:
A powered floor sweeper comprises a foot assembly with a motor driven primary agitator and a pair of edge agitators coupled to wheels such that manual propulsion of the sweeper rotates the wheels and thereby the edge agitators. The sweeper includes a slip clutch mechanism to protect the primary agitator and the motor in case the agitator become jammed. Additionally, the sweeper comprises a ramp assembly along an agitator opening to help collect dirt and dust at the primary agitator. A dust bin removably mounted in an open top dust bin recess is in communication with the agitator opening and receives the dirt and dust collected at the agitator opening. Furthermore, the sweeper comprises a handle assembly having a detent mechanism that interacts with a pivot cradle in the foot assembly to retain the handle assembly in a generally vertical position.
