Tank capacities vary widely — from compact units with about 600 mL (20 oz) capacity up to larger multi‑liter tanks around 2,100–2,500 mL (about 71 oz to 5.29 pints).

Review summaries commonly report fast, effective cleaning that restores sparkle and shine. Many users describe quick, noticeable improvements in appearance after cleaning.

These cleaners are marketed for many small items, including eyeglasses, watches, dentures/retainers, coins, necklaces, earrings, razor blades, toothbrush heads, and small household tools or utensils.

Common accessories include dipping or plastic baskets, small cleaning brushes, and watch holders or stands.

Products suggest using tap water in ultrasonic cleaners (adding a few drops of dish soap can help), replacing the solution with fresh liquid as needed, and using the included cleansing brush for liquid cleaners.
