An ultrasonic waterjet apparatus () has a mobile generator module () and a high-pressure water hose () for delivering high-pressure water from the mobile generator module () to a hand-held gun () with a trigger and an ultrasonic nozzle (). An ultrasonic generator in the mobile generator module () transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer () which vibrates to modulate a high-pressure waterjet flowing through the nozzle (). The waterjet exiting the ultrasonic nozzle () is pulsed into mini slugs of water, each of which imparts a waterhammer pressure on a target surface. The ultrasonic waterjet apparatus () may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus () performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect A nozzle with multiple exit orifices or a rotating nozzle () may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient. A water dump valve () and controlling solenoid are located in the mobile generator module () rather than the gun () to make the gun lighter and more ergonomic.
