Description

ABSTRACT:
A vacuum cleaner with an air vibration suction nozzle for application to a workpiece, whereby air vibrations produced by a transducer supported and sealed in the nozzle housing vibrate the workpiece, or debris with respect to the workpiece, and any loose particles on the workpiece are then drawn into the vacuum cleaner through the suction nozzle. The suction nozzle is provided with an elongated nozzle opening, a plurality of wheels to guide the nozzle over the workpiece, a stationary brush adjacent the nozzle opening, and a viewport and interior light for illuminating and viewing the workpiece through the nozzle opening. Controls for adjusting both the frequency and amplitude of the airwaves produced by the transducer are also provided. The suction nozzle can also be fitted with a plurality of air holes disposed within the nozzle housing adjacent the nozzle opening, which openings can be selectively opened or closed, and a suction nozzle can be constructed to slidably engage upon the workpiece without the use of wheels.
