Abstract
A floor cleaning machine for cleaning a surface includes a body having a suction nozzle thereon, a handle pivotably coupled to the body and having a motor housing portion, and a suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle. The floor cleaning machine also includes a recovery tank coupled to the handle in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle and an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, and the other when pivoted to a reclined position. The hose at least partially wraps around the motor housing portion when in the expanded configuration.
