Abstract
A recirculating system is provided for use with a cleaning machine including a recovery tank and a heated fluid solution dispensing tank for recirculating a part of the heated fluid passed from the dispensing tank to a hand-held fabric cleaning head. A normal vacuum hose connects a suction chamber in the hand-held cleaning head to the recovery tank of the machine. A dispensing fluid outlet line and a dispensing fluid return line are both preferably contained within the vacuum hose. The ends of the fluid inlet line and fluid outlet line at the machine extend laterally through appropriate fixtures from the vacuum hose to outlet and return inlet ports of the fluid dispensing tank. The far distal ends of the fluid outlet line and fluid inlet line at the hand-held head in turn connect to a block member having a third outlet for passing a portion of the dispensing fluid directly to a spray nozzle in the outlet head. The block structure is arranged to pass another part of the fluid back through the inlet line to the dispensing tank so that continuous recirculation takes place and the fluid dispensed from the nozzle is maintained in a heated condition.
