When ultrasonic waves propagate in a liquid, the sudden change in sound pressure causes intense cavitation and emulsification in the liquid. Every second, millions of tiny cavitation bubbles are generated. Under the action of sound pressure, these bubbles are rapidly produced in large quantities and continuously burst violently, generating powerful impact force and negative suction force, which is sufficient to remove stubborn dirt and kill bacteria and viruses. (Special materials can be asked for clarification before cleaning.)
