EXTRACTOR CLEANING MACHINE
First Claim
1. An extractor cleaning machine comprising:
- a base movable along a surface to be cleaned, the base including an agitator;
a distribution nozzle;
a suction nozzle;
a suction source in fluid communication with the suction nozzle, the suction source operable to draw fluid and dirt from the surface through the suction nozzle;
a recovery tank supported by the base, the recovery tank in fluid communication with the suction source to receive and store the fluid and dirt drawn through the suction nozzle;
a supply tank supported by the base, the supply tank in fluid communication with the distribution nozzle to supply cleaning fluid to the distribution nozzle;
a pump in fluid communication with the supply tank and the distribution nozzle to deliver fluid from the supply tank to the distribution nozzle;
a motor operable to drive the agitator and the pump, the motor including an output shaft; and
a drive mechanism coupled to the output shaft of the motor, the agitator, and the pump, the drive mechanism operable to selectively connect the agitator and the pump to the motor to alternately drive the agitator and the pump.
