Patent number: 9788699Abstract: A liquid extraction cleaning device comprises a main unit, a liquid pump, a flexible hose, and a hand tool. The main unit comprises a vacuum pump. The hand tool comprises a vacuum inlet port, an agitator, a spray nozzle, and a grip portion. The vacuum inlet port of the hand tool is operatively connected to the vacuum pump via the hose passageway in a manner such that the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the hose passageway. The spray nozzle is operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing liquid out of the spray nozzle.Type: GrantFiled: January 29, 2015Date of Patent: October 17, 2017Assignee: RUG DOCTOR, LLCInventors: Timothy Wall, Ann Marie Morrow, Walter Haug, Phuong Le, Charles Michael Ostendorf, Schubert Pereira, Ernest Matthew Chavana, Jr., Vincent Lau, Jason Edward Hill, Jason Tilk, Evan Spirk, Lindsey Tufts, Craig Saunders, Paul Stephens
