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.

A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

A cleaning head assembly for a surface maintenance machine comprising a cleaning tool having a tool adapter, a driver adapted to provide a generally rotational motion to the cleaning tool to clean the floor surface, the driver being releasably connected to the tool adapter of the cleaning tool by a hub, and an aligning receptacle coupled to the tool adapter of the cleaning tool and positioned between the hub and the tool adapter, the aligning receptacle having an receptacle opening for receiving the hub, wherein the aligning receptacle is adapted to guide and matingly seat the hub into the receptacle opening and thereby engage the cleaning tool to the driver such that the cleaning tool and the driver are rotationally aligned and a rotational motion of the driver is transferred to the cleaning tool by the hub.

Disclosed is a versatile trailer that may be towed from job site to job site by a vehicle and within a job site be towed by a maintenance cart. The trailer may function as a mobile sweeper to clean smaller parking lots found at schools and parks as well as sweep pathways, lawns, and sidewalks to remove litter, debris, and plant waste. The trailer contains a hopper to collect material both swept by the broom from the area below the trailer as it is towed as well as allowing material to be deposited into the hopper from above the trailer. The hopper is designed so as to allow any material contained within the hopper to be deposited onto the ground or into a dumpster. Finally the trailer is designed so that the electrical power source used to operate the broom and the hopper lift mechanism may be concurrently used by maintenance workers to supply electrical energy needed to operate any electrically based power tools and equipment.
