I am leaning toward the model with the two big control knobs for time and power. Instead of the digital panel, which is probably less reliable.

There is no real gain for the digital model but I got a deal for it.

Spare parts are available if they are like the one I bought.

The main tank is made of stainless steel, mine developed a tiny pin hole through which cleaning fluid leaked onto the electronics. I silver soldered the hole and replaced the driver unit that had shorted out.

Spare parts. What a concept!
I see the list of spares ends with a package of JB Weld. When all else fails, JB Weld, the last resort.

Knut, if you are looking at a 30L Vevor, you should know that some have 8 transducers and are rated at 480 watts of "cleaning power", and some have 10 transducers and are rated at 600 watts of "cleaning power". Not all clearly identified.
To add to the confusion, some of the descriptions of the machines are clearly incorrect.
Proceed with caution.

All the transducer units on the underside of the main tank are attached by screwing onto a stud welded to the bottom of the tank but also epoxied on. The epoxy gives a direct contact between transducer and tank so the ultrasonics pass directly into the tank. That was another fix, saw that 2 had no bubbles so did the foil test to see that they no longer worked so replaced them. You unscrew the old ones off, clean off the old epoxy and epoxy the replacements on. On any holes in the tank epoxy only lasts so long as a repair, the ultrasonic gets to it over time. Only the silver solder has permanently fixed tank leaks

Do the stainless tanks wear out?
I noticed some of the Vevor tanks claimed to be made of 304 alloy. Perhaps an upgrade? Or perhaps it makes no difference.

They must wear out eventually, mine had a weak point probably a rolled in piece of swarf so it went there first as it was so thin. Mine is 10 years old now and the weak spot appeared after 18 months, the rest of the tank is still like new.

I hopefully haven't missed the answers:

Does anyone have one they can put a head, cylinder, or crankcase half in and clean without turning? Those are the things I clean in my kitchen sink that I would like to make easier. Don't give a crap about cleaning small stuff - already have good ways to do that.

Do you put greasy/road grime parts in to clean or have you pre-cleaned them?

f you do go ‘too big’ and have regrets when you only want to use it for some small parts, bearing mind the expense of filling with fresh fluids, you can use a smaller container within the large one

So here is a hair brained off the wall thought I just had.

Say your basket cannot fit a cylinder head due to the height. How about using an intermediate container that is deep enough to submerse the head in??

Do a search for "Immersible Ultrasonic Transducers". These run from very expensive to about $60 on Amazon. I have the original Kick-Starter version of the clone sold on Amazon and it's still working. It's great for carb part sized bits. I've had mixed results with bigger parts...It has a very limited range of effectiveness.

Has anyone built there own unit from scratch would be interested to know how you got on with the build & how the unit performs
Did you go 28 or 40Mhz
How many transducers did you fit...

Stephen Hill · Jan 25, 2026

The bigger the unit, the more transducers required. The better 30 litre units have 10, 22L have 8, 15L have 6, 6L have 3, etc.
Typically the transducers use 60 watts. Most of the units spec 40Mhz.
Look at the ultrasonic power wattages by volume in "ready built" units and you can figure out how many transducers you need.

I'm researching and thinking about getting a square (rounded corners) stainless steel catering wash basin/sink and securing possibly 12 28Khz 60watt transducers. mounting them on stainless studs silver solder to the underside with an epoxy adhesive between both
Still work in process on drivers, controls etc.
People who have made these are recommending you need 25watts of power per 2.5lts of liquid
I have also considered round stainless catering cooking pots as the tank
In principle it doesn't look to difficult a challenge

I second getting a much larger unit. I am getting by with a very small Harbor Freight one, sized to match my tiny shop. At times even my unit is too large for the job, so I put the parts into a ziplock bag with the chosen chemicals and then add enough water to keep the bag submerged. What really sucks on my cheap unit is that the heater will only run about 5 minutes and then has to be reset. Maybe if I wait long enough the parts would come clean without heat.

I love my ultrasonic cleaner.. I have 30 litre unit an can almost get most of a triumph half case in it so I have to flip it to finish it off. I had a smaller ultra sonic cleaner for smaller items but burnt that out. Now I have to insert a smaller container in my big unit.
When you looking for an ultrasonic cleaner do you research and check reviews. There's lots if junk out there. I've had my big one for 6 years now without an issue.
