According to the manufacturer, this cleaner uses advanced tech with 42,000 Hz sound waves to get rid of dirt on stuff like jewelry, eyeglasses, and metallic watchbands. It makes tons of tiny bubbles that clean without damaging the items, and it's nice that you can just use tap water, which is pretty eco-friendly.
