Should I see bubbles when the jewelry cleaner is running?

The ultrasonic cleaner uses a process called cavitation to clean. Cavitation occurs when small bubbles collapse, creating a small shockwave which cleans your items. These bubbles are microscopic and are not visible to the naked eye. You may see ripples on the surface of the water or cleaning liquid, and debris in the water if you are cleaning heavily soiled items.
