Extraction cleaning with tank mounting
View Patent ↗A portable extraction surface cleaner has a base housing, an upright handle pivotally mounted to the base housing, a liquid dispensing system including a cleaning fluid supply tank for holding a supply of cleaning liquid and removably mounted in a well in the base housing, a liquid recovery system that includes a recovery tank, a suction nozzle, a working air conduit extending between the recovery chamber and the suction nozzle and a vacuum source to draw soiled liquid from the suction nozzle into the recovery tank. The vacuum source is mounted in an enclosed chamber juxtaposed to the well. A detergent supply tank is removably mounted in a second well in the base.
1. A portable surface cleaning apparatus, comprising:
a base housing adapted for movement along a surface to be cleaned;
an upright handle pivotally mounted to the base housing;
a liquid dispensing system comprising:
a liquid dispenser associated with the base module for applying liquid to a surface to be cleaned;
a liquid supply tank for holding a supply of cleaning liquid;
a liquid supply conduit fluidly connected to the liquid supply tank and to the dispenser for supplying liquid to the dispenser;
a liquid recovery system comprising:
a recovery tank removably mounted on the base housing and having a liquid recovery chamber for holding recovered liquid;
a suction nozzle associated with the base housing and adapted to draw dirty liquid from the surface to be cleaned;
a working air conduit extending between the recovery chamber and the suction nozzle;
a vacuum source in fluid communication with the recovery chamber for generating a flow of working air from the nozzle through the working air conduit and through the recovery chamber to thereby draw dirty liquid from the surface to be cleaned through the nozzle and working air conduit, and into the recovery chamber to thereby recover the dirty liquid from the surface to be cleaned;
the improvement comprising:
the base housing includes a well for selectively receiving the liquid supply tank and the base housing further includes an enclosed chamber juxtaposed to the well and the vacuum source is mounted in the enclosed chamber.
2. A portable surface cleaning apparatus according to claim 1 and further comprising a detergent supply tank removably mounted in a second well in the base for holding a supply of concentrated cleaning solution and operably fluidly connected to the liquid supply conduit for supplying a mixture of concentrated cleaning solution and water to the liquid dispenser.
3. A portable surface cleaning apparatus comprising:
a base housing adapted for movement along a surface to be cleaned;
an upright handle pivotaily mounted to the base housing;
a liquid dispensing system comprising:
a liquid dispenser associated with the base module for applying liquid to a surface to be cleaned;
a liquid supply tank for holding a supply of cleaning liquid;
a liquid supply conduit fluidly connected to the liquid supply tank and to the dispenser for supplying liquid to the dispenser;
a liquid recovery system comprising:
a recovery tank removably mounted on the base housing and having a liquid recovery chamber for holding recovered liquid;
a suction nozzle associated with the base housing and adapted to draw dirty liquid from the surface to be cleaned;
a working air conduit extending between the recovery chamber and the suction nozzle;
a vacuum source in fluid communication with the recovery chamber for generating a flow of working air from the nozzle through the working air conduit and through the recovery chamber to thereby draw dirty liquid from the surface to be cleaned through the nozzle and working air conduit and into the recovery chamber to thereby recover the dirty liquid from the surface to be cleaned;
the improvement comprising:
the base housing includes a well for selectivly receiving the liquid supply tank and further and comprising a detergent supply tank removably mounted in a second well in the base for holding a supply of concentrated cleaning solution and operably fluidly connected to the liquid supply conduit for supplying a mixture of concentrated cleaning solution and water to the liquid dispenser.
