Abstract: A sonic cleaner for small articles includes two tanks for receiving a liquid and articles to be cleaned and a base unit having chambers for receiving each tank. A vibratory motion generator attaches to the base unit through an isolating structure. Complementary attachment elements on the vibratory motion generator and each tank form a releasable, rigid connection. When the tank is attached to the vibratory motion generator, liquid in the tank can be agitated. When the releasable, rigid connection is detached, the tank can be removed from the base unit for disposing of liquid in the tank without having to handle the entire sonic cleaner.
