A system for cleaning fabric-like surfaces, such as carpet, fabric, upholstery, and the like is disclosed. The system includes a Y-type connector for receiving and mixing pressurized air and pressurized cleaning solution to produce a mixture thereof. In addition, the system includes a nozzle in communication with the Y-type connector for atomizing the mixture to produce atomized cleaning solution, which is sprayed onto a fabric-like surface to clean the surface. A supply source for supplying the Y-connector with pressurized cleaning solution is also provided, as well as a pressurized air source for supplying the Y-connector with pressurized air. In addition, the system includes a vacuum generating mechanism for generating suction to remove cleaning solution having been sprayed onto a fabric-like surface.

[ I claim:] [1.] A system for cleaning a fabric-like surface such as carpet, fabric and upholstery, said system comprising:atomizing means including nozzle means for mixing and processing pressurized air and pressurized cleaning solution to produce a substantially foamless atomized cleaning solution

[ I claim:] [1.] A system for cleaning a fabric-like surface such as carpet, fabric and upholstery, said system comprising:atomizing means including nozzle means for mixing and processing pressurized air and pressurized cleaning solution to produce a substantially foamless atomized cleaning solution, said nozzle means also for spraying the atomized cleaning solution onto a fabric-like surface to clean the fabric-like surface;cleaning solution supply means for supplying said atomizing means with pressurized cleaning solution;air supply means for supplying said atomizing means with pressurized air; andvacuum means for removing the cleaning solution having been sprayed onto the fabric-like surface. [13.] A method of cleaning a fabric-like surface such as carpet, fabric and upholstery, said method comprising:providing a system including:atomizing means including nozzle means for mixing and processing pressurized air and pressurized cleaning solution to produce a substantially foamless atomized cleaning solution, said nozzle means also for spraying the foamless atomized cleaning solution onto a fabric-like surface to clean the fabric-like surface;cleaning solution supply means for supplying said atomizing means with pressurized cleaning solution;air supply means for supplying said atomizing means with pressurized air; andvacuum means adjacent said nozzle means for removing the cleaning solution having been sprayed onto the fabric-like surface;supplying pressurized air and pressurized cleaning solution to the atomizing means at predetermined pressures respectively to atomize the cleaning solution without generating substantial amounts of foam;spraying a fabric-like surface with the atomized cleaning solution; andremoving the cleaning solution from the fabric-like surface immediately after it is sprayed thereon. A method as claimed in claim 13 wherein the atomizing means is continuously supplied with the pressurized air and the pressurized cleaning solution to continuously atomize the cleaning solution which is continuously sprayed on the fabric-like surface and wherein the cleaning solution is continuously removed from the fabric-like surface immediately after it is sprayed thereon. A method as claimed in claim 13 wherein the spraying and removing steps are carried out simultaneously such that the cleaning solution is removed from the fabric-like surface immediately after it is sprayed thereon. A method as claimed in claim 13 wherein the spraying and removing steps are carried out simultaneously and continuously over a period of time which is sufficient to clean a desired area of fabric-like surface. A method as claimed in claim 13 which is carried out without brushing the fabric-like surface. A method as claimed in claim 13 wherein the pressurized air supplied by said air supply means has a pressure of between about 25 and 175 psi. A method as claimed in claim 13 wherein the pressurized air supplied by said air supply means has a pressure of between about 60 and 140 psi.
