ABSTRACT:
An extractor having a cleaning solution line which extends from the solution tank to a non-self-priming pump and to the normally closed valve which controls the flow of liquid on to the cleaning head. The extractor uses a manually operated priming pump to draw cleaning solution from the solution tank through the cleaning solution line to the non-self-priming pump. Following activation of the manually operated priming pump, a check valve directs the cleaning solution to the operating non-self-priming pump to effect priming of said pump. Solution is then controlably pumped past the fluid flow control valve to the cleaning head. The check valve remains open while the pump is in operation.
