Tank volume, frequency and heat, read for what goes in the basket
An ultrasonic cleaner fills a tank with sound waves that make tiny bubbles collapse against a surface, lifting dirt from places a brush cannot reach — printer nozzles, soldered boards, small resin parts, tools. Tank volume is quoted in liters and the internal dimensions matter more: a long, shallow tank takes a part that a larger square one will not. Frequency is published in kilohertz, and lower frequencies clean more aggressively while higher ones suit delicate items — some units switch between two. Ultrasonic power is a watt figure that describes the transducers, often printed beside a separate heater power, and the two must not be added together or confused. A heater helps with grease; a timer and a basket that keeps parts off the tank floor protect both. A drain valve makes emptying a large tank manageable. Then the liquids: water with a suitable detergent works for most jobs, and the maker lists what the tank tolerates — flammable solvents are commonly excluded from ultrasonic tanks, and electronics are cleaned only when their own maker allows it. We compare tank volume and dimensions, frequency, ultrasonic and heater power, timer, basket, drain and permitted liquids.

Transducers generate cavitation in a liquid. This site publishes specifications and describes no protocol.
The vibration regime of the transducers, published in kilohertz. It characterizes the type of cleaning aimed at.
No: the permitted liquids published by the manufacturer prevail. This site recommends no product.
It is published together with ultrasonic power. Its usefulness depends on the liquid and the soiling.
Avoiding direct contact between parts and the bottom. Its presence is published.
The published drain says so: tap, plug or tipping depending on the model.
The published volume and dimensions must allow the treated parts to be fully submerged.
Some manufacturers mention it. This site reports what is published and prescribes no chemical use.
Compare internal dimensions, not liters, and check which liquids the maker allows in the tank.
Four machines in five must publish the value before a column is raised. Below that, it would be comparing absences.
