Abstract

A rotating head mounts a nozzle which creates cavitation in a pressurized fluid such that a surface may be quickly and efficiently cleaned. The rotation of the nozzle ensures a relatively wide cleaning path. The cavitation allows cleaning using only the pressurized fluid jet without any necessary abrasives, while still fully utilizing high rotational speeds. A preferred cavitating jet nozzle is also disclosed for producing cavitation in the pressurized fluid. The cavitating jet nozzle includes a pin received at a central position which lowers the pressure of the pressurized fluid such that cavitation bubbles form in the fluid. The pin is self-centering within the nozzle since it is free floating relative to a securing member which retains the pin in the nozzle. In addition, the pin preferably has an end face upstream of an outlet portion of the nozzle.
