Abstract
A floor sweeper for recovering material from a surface to be cleaned comprises a handle assembly pivotably attached to a foot assembly. The foot assembly comprises a housing forming a brush chamber having a bottom opening. The foot assembly comprises a pair of driving gears and a split brush assembly rotatably mounted within the brush chamber and adapted to contact the surface through the opening. The brush assembly comprises two separately-rotatable halves each corresponding to one of the driving gears, with each half comprising a brush core, brush paddles or bristles affixed to an exterior of the brush core, and a brush gear adapted for rotation with the brush core. Each brush gear is driven by a corresponding driving gear to the corresponding brush core as the floor assembly is moved across the surface in order to drive the brushes to cleaning of the surface.
