A sink system includes a sink basin and a disposal system. The disposal system includes a first inlet coupled to the sink basin, a second inlet fluidly coupled to a second fluid source, and a garbage disposal configured to receive a first flow of fluid from the sink basin via the first inlet and receive a second flow of fluid from a second fluid source via the second inlet. The sink basin delivers a flow of used water to the disposal system and the second fluid source delivers a flow of clean water to the disposal system.

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.
