Abstract:
A sweeper assembly for a motorized vehicle adapted for operationally moving in a direction of translation over a floor surface, the sweeper assembly comprising:a containment housing having a lower wall and defining a chamber having a debris inlet:a sweeper brush for contacting the floor surface and displacing debris from the floor surface, the sweeper brush being an elongated rotary brush having a central rotational axis disposed transversely in the housing, said sweeper brush operationally sweeping the floor surface in the direction of translation for forward rotation about said central rotational axis, said sweeper brush thereby pushing debris from the floor surface forward into a receiving area within said housing, said lower wall being located forward from the sweeper brush and disposed above the floor surface;an auger brush operationally sweeping displaced debris deposited in the receiving area toward the debris inlet, the auger brush being elongated and having a central rotational axis disposed transversely in the housing above at least a portion of said lower wall and having brush members extending in a helix pattern; anda vacuum source in communication with a vacuum passageway operably coupled to said debris inlet.
