    I got one a while ago and they are great for cleaning small objects, and glasses. Basically ultrasonic sound waves get send through water, small cavitation bubbles form and rip off the dirt.

      Real ones are great but definitely more expensive. My wife has one that uses liquid and she puts jewelry in. Works extremely well.
