Abstract
A powered floor sweeper having a nozzle housing formed of a plurality of segments and tie elements extending through the segments for retaining the segments in assembled side-by-side relationship. The assembled segments define open ends closed by end caps also secured in the assembly by the tie elements. A pivotable door is secured to the nozzle housing by a tie element and cooperating retaining structure is provided on the door and assembled nozzles for retaining the door releasably in a position closing the dirt-collecting space of the nozzle housing. The device further includes a sweeper brush rotatably carried in the housing and a powered drive for forcibly rotating the brush. Internal baffles separate the sweeper brush bearing zone from the dirt-collecting space. The brush bristle tufts are arranged in preselected spaced relationship to effectively minimize and substantially preclude dust puffing in the operation of the floor sweeper.
