Abstract
An apparatus for cleaning a floor includes a housing, chassis, wheels, motor, steering mechanism, cleaning assembly, optionally a squeegee assembly, and at least one of a side sweeping system, front sweeping system, and pick-up system. The side sweeping system includes a turntable with central axis, a drive wheel disposed in coaxial relationship with the turntable, a sweeper motive device in communication with the drive wheel, a plurality of brushes distributed radially around the drive wheel and adapted to be driven by rotation of the drive wheel, and a pivoting connector configured to enable the side sweeping system to pivot laterally in response to contact with a wall while at least one of the brushes maintains contact with the floor adjacent the wall while the apparatus is in operation, and the brushes move debris disposed on the floor adjacent the wall toward the front of the apparatus.
