A water vapor cleaning system includes a vapor-producing chamber in communication with a water source, e.g. a hot water line, of an existing plumbing system. The vapor-producing device includes a vapor exit. The cleaning system includes a nozzle having an inlet, an outlet, and a valve selectively allowing or denying fluid communication between the inlet and outlet. The nozzle includes an actuator for selection between allowing or denying fluid communication. The nozzle is connected to the vapor-producing chamber with tubing. The nozzle also includes a vacuum device for suctioning items or blowing air through the tubing. A selector switch on the nozzle facilitates selection between steaming, vacuuming, blowing, soaping, and rinsing modes. A set of nozzle accessories are included for cleaning various types of surfaces.
