Rug and carpet cleaner |
摘要 |
A mobile rug or carpet cleaner is provided with a support housing having front and rear wheels mounted so that the unit is tilted about the housing axis of the front wheels to engage and disengage a cleaning head with the carpet to be cleaned. The cleaner includes a fluid delivery system which provides fluid flow to the cleaning head, an auxiliary cleaning head and a spotter. The fluid delivery system utilizes a pump having an open conduit which continuously recycles cleaning fluid to a reservoir. The continuous recycle allows a solenoid valve in a line transporting fluid to the cleaning head spray nozzles to be abruptly closed without subjecting the entire fluid delivery system to a sudden, potentially damaging increase in fluid pressure. An automatic drain system utilizes a vacuum line to direct spent cleaning fluid to a removable waste tank for disposal. Suction can be selectively directed to the cleaning head or to the auxiliary head.
