Abstract
A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.
