Abstract: A dual mode carpet cleaning machine capable of being used in both a traditional deep cleaning mode and a fast drying surface cleaning mode. A selection mechanism provides selective communication with different sets of application jets. One set of application jets delivers a first cleaning solution that penetrates deeply into a carpet. After agitation with a scrub brush the device removes the cleaning solution and unwanted soil through a vacuum nozzle. The other set of jets delivers a lower flow rate of a second cleaning solution that does not penetrate deeply into the carpet. In addition, a novel cleaning solution is disclosed for use with the machine in differing concentrations, depending on the desired application. The carpet cleaning solutions dry more quickly when applied to carpet than previous solutions; the combined performance of the system displays similar cleaning efficiencies to previous carpet cleaning machines but obtains significantly reduced drying times.

Abstract: The invention is a cleaning tool housing assembly and a replaceable cleaning assembly. The manifold, in combination with a fluid intake element, also delivers fluid (under pressure through holes in the manifold located in a longitudinal channel) to a sponge. Two spaced apart fluid barriers are longitudinally disposed in the sponge. As fluid is introduced into the center of the sponge, between the fluid barriers, the fluid travels toward the opposite surface of the sponge. The fluid is prevented from traveling laterally due to the fluid barriers. As vacuum pressure, negative pressure, is exerted on the outer portions of the sponge (on each side of the fluid barriers), fluid is pulled back through the sponge, through the manifold and through the nozzles into the hollow housing body.

Abstract: A tubular plastic handle for a steam cleaning machine with a T-shaped hollow member to which is integrally attached a hollow outrigger supported on hollow posts. The posts provide an integral cord wrap and the outrigger improves flexural rigidity. The hollow member also includes an aperture further improving flexural rigidity through which a linkage controlling the angle of the handle may be accessed.

Abstract: A steam cleaning machine has a vacuum pump seated in a recess in a top of a main support housing and a first conduit resiliently sealed in a channel leading under the recess and connecting the first conduit with the air inlet of the pump. The first conduit passes through a vacuum cover which is fitted over the top of main support housing and is attached to a dome which is resiliently sealed to a recovery tank, while a second conduit is connected to the exhaust of the pump. A third conduit is connected to a vacuum nozzle, passes through vacuum cover and is also attached to the dome which is supported by first and third conduits from the vacuum cover. An adjustable handle is pivoted at the back of main support housing.

Abstract: A steam cleaning machine wherein the clean water tank serves as a chassis for the machine. A main support housing and a recovery tank is mounted on top of the clean water tank which has an upwardly bowed bottom forming a cavity within which is mounted a spray nozzle and a vacuum nozzle. The clean water tank is mounted on wheels, an axle of which passes through the clean water tank. The spray nozzle is mounted on a pan saddled in the cavity and the vacuum nozzle is received in a pair of lateral grooves and a notch formed in the cavity for that purpose.
