A portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

A dirt removing device including: a cassette mechanism having a head formed with a beating face, a liquid accommodating portion for accommodating liquid, and a water supplying passage which is started from the liquid accommodating portion and penetrates into the entire head; and a device body having a vibration unit. The cassette mechanism is detachably received in the vibration unit, and the vibration unit, when being powered, causes the cassette mechanism to vibrate in a direction substantially orthogonal with the beating face of the head. The liquid is supplied from the liquid accommodating portion to the beating face of the head through the water supplying passage, along with the vibration of the cassette mechanism caused by the vibration unit.

A laundry appliance includes a drum that rotationally operates within a tub. The drum defines a processing space for treating articles. A fluid delivery system selectively delivers wash fluid into the processing space. A hemispheric ultrasonic transducer is positioned proximate a base of the drum. The hemispheric ultrasonic transducer selectively directs waves of an ultrasonic frequency in a hemispheric radiating pattern through the processing space. The waves generate air bubbles within the wash fluid and the waves cause the air bubbles to implode and release micro air jets that are directed into the wash fluid for sanitizing the articles. The micro air jets act on the articles to loosen and remove foreign material therefrom.
