Abstract
A floor cleaning machine including a base including a suction nozzle and a distribution nozzle, a handle pivotably coupled to the base about a pivot axis, a supply tank assembly coupled to the handle, and a suction motor assembly in fluid communication with the suction nozzle. The floor cleaning machine further 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 an expanded configuration when the handle is pivoted to a substantially upright position and the hose is in a retracted configuration when the handle is pivoted about the pivot axis to a reclined position and the hose at least partially wraps around the pivot axis in the expanded and the retracted configurations.
