The adoption of advanced energy-saving technologies has allowed an ultrasonic washing device to be developed for household use. Ultrasonic washing is conducted by compressional and rarefactional waves which are periodically formed in the volume of liquid and appear in a practically incompressible medium (water). Clothes and other objects that require cleaning placed in such a liquid are subjected to intensive hydro acoustic effects. Hydro-acoustic waves initiate the occurrence of ultramicroscopic gas bubbles which contribute to the separation of dirt microparticles from the clothes so ‘washed’, or in general, the object to be cleaned.
