Problems solved by technology

While known extractors have proved useful for cleaning carpets, upholstery and other fabrics and textiles, this second rinsing step has been found to be inconvenient and time consuming because remnants of the cleaning fluid often remain in the fluid conduit between the fluid reservoir (or reservoirs) and the conduit outlet.
Such flushing may be inconvenient, and may waste cleaning solution.
Similar problems may arise when using dry chemical extraction devices.

Abstract

A cleaning device having a housing, a hose assembly and a cleaning head. The housing has a first supply tank to contain a first fluid, a recovery tank, a vacuum fan to generate a working air flow through the recovery tank, and a fluid pump having an inlet and an outlet. The pump inlet receives the first fluid from the first supply tank. The hose assembly has a proximal end connected to the housing and a distal end freely moveable relative to the housing, and includes a vacuum hose in communication with the recovery tank and a fluid hose in communication with the pump outlet. The cleaning head is connected to the distal end of the hose assembly, and has an inlet nozzle and a fluid deposition system. The fluid deposition system has a second supply tank to contain a second fluid, a fluid mixer to mix the first fluid with the second fluid, and a first fluid sprayer downstream from the fluid mixer. The second supply tank is selectively removable from the cleaning head and has a dry-break valve that automatically seals the second supply tank upon its removal from the cleaning head.

Description

FIELD OF THE INVENTION [0001] The present invention relates to extraction cleaning devices for floor, upholstery and fabric care. BACKGROUND OF THE INVENTION [0002] Many types of cleaning devices are available for commercial and consumer cleaning needs. While conventional vacuums are popular for general floor cleaning, various types of extraction cleaners have been developed to provide deeper or more problem-specific cleaning operations. Extraction cleaners generally use a liquid or dry composition depositing system in conjunction with a vacuum source to deposit a cleaning substance on the surface being treated, then recover the deposited cleaning substance and any entrained dirt or debris back into the extractor. Extractors can also be used or adapted to deposit other types of compound on the surface, such as sealers and protectants. Like vacuums, extractors are provided in many different forms, such as upright, portable, canister, and handheld. [0003] Typical wet extractors use a ...
