Ultrasonic Cavitation: The cleaning effectThe imploding bubbles in the water rapidly create high temperatures and pressures in a tiny space. When the implosions come into contact with the submerged item, the cavitation bubbles act like microscopic scrubbing brushes all over the cleaning tank, removing dirt without necessarily requiring chemicals. The action is miniscule so that it provides a highly effective but gentle clean, avoiding the damage that can be caused when scrubbing items by hand.
