Abstract
A hand held steam vacuum is provided that is operated by way of a single switch device. The vacuum is generally comprised of a vacuum fan, a water pump, a heating element, and a fluid supply tank in fluid communication with a fluid discharge outlet. In operation, the vacuum fan is operable to suck debris into a collection bowl residing in the vacuum. In addition, the water pump is operable to drive fluid from the fluid supply tank via fluid transport tubes to the fluid discharge outlet, and the heating element is operable to heat the fluid prior to it being discharged from the fluid discharge outlet. A single switch device is configured to control operation of the vacuum fan, water pump and heating element.
