APPARATUS AND METHOD FOR CLEANING SURFACES

摘要

A method for cleaning surfaces having the steps of depositing a cleaning fluid onto the surface from a cleaning fluid reservoir on a wet extractor, contacting the surface with a hand-held ultrasonic spot cleaner, applying ultrasonic vibrations to the surface using the hand-held ultrasonic spot cleaner to help release soil form the surface, and removing the cleaning fluid and soil using the wet extractor. A wet extractor having an ultrasonic cleaning component is also provided. Further provided is a combined cleaning system having a cleaning device and a hand-held ultrasonic spot cleaner. The cleaning device has a dirt receptacle, a nozzle adapted to be positioned adjacent a surface to be cleaned, and a vacuum source adapted to generate a working air flow from the nozzle to the dirt receptacle. The hand-held ultrasonic spot cleaner includes an ultrasonic wave generating source, an ultrasonic cleaning head adapted to be driven by the ultrasonic wave generating source, and a control switch adapted to selectively activate the ultrasonic wave generating source. Multiple variations thereof are also provided.
