VEVOR Commercial Ultrasonic Cleaner 6L Professional Ultrasonic Cleaner 40kHz with Digital Timer&Heater 110V Excellent Cleaning Machine for Watch Instruments Industrial Parts Excellent Cleaner Solution

This is specifically for the "2L" model.First the not so good. The basin does not hold 2 liters, it holds approximately 40 ounces. The stock images on the listing shows this model as having a drain valve, it does not. The lack of drain valve was not a deal breaker for me.On to the good, the unit works well at ultrasonic cleaning. The heater gets hot, but remember there are separate on/off switches for the heater and the ultrasonic cleaner. If you need things very hot, try warming the liquid in a microwave safe container then pouring it into the ultrasonic cleaner.So far I've cleaned jewelry, multitools and some Warhammer 40K minis. The pictures attached shows the progression of stripping the model. First with water in the cleaner, then with Simple Green in the the cleaner, then isopropyl alcohol but not in the cleaner. Water didn't do too much by itself. But with simple green it worked pretty well. There was not too much more for the alcohol to work on after the simple green.The next time I use the machine to strip a miniature, I'll just go straight to simple green and be done.

I like this unit. Big enough for good sized parts. Comes with a small part screen cage to put your tiny pieces in. Does an amazing job. Does need to heat up before you run the vibration cycle, but does get there. May take over an hour to heat up your solution, but works great and since most ultrasonic cleaners don't even have the heat, it is just an added benefit. Price is great for this

Get at least one size bigger than what you think you will need. I bought a 6 liter machine for cleaning bike parts, but it is not big enough. When I clean mountain bike cassettes with very large gears, only a bout 3/4ths of it will be submerged. I'm also pretty sure 6 liters would overflow the tank. For actual use, you can put about 4 liters of liquid in it and still have room for a few parts. If you are cleaning small items, I recommend filling the tank with straight water and putting your part in a sealed glass jar with degreaser. It works really well, my only complaint is the drain hose. The plastic barb leaks and the flimsy hose kinks. I will replace it with a brass barb and a short piece of automotive heater hose. The buzzing noise is not nearly as annoying as I thought it would be, I am capable of tuning it out.

I am using this to clean rocks and agates that I am cutting. It does a great job in removing packed-in grit and mud. It also does a good job cleaning the fine-sized dust and grit when I am done cutting rocks. The machine seems well-built. Thanks!

4 days after the 30 day return period, it no longer heats up or vibrates. The light on the power switch on the back lights up, but the front does not turn on. The LEDS on the front will blink on and off when you hit the power switch in the front, but after that the front temperature and time remain blank.UPDATE:I emailed them on April 15, 2025 the day that the device failed.Received a reply within 24 hours, they asked that I take apart the device and send a picture of the "driver board" the same day.They reply that they would be sending a replacement driver board. Fortunately I it is an easy process with unscrewing a few screws and swapping plugs.New board arrives on arrives on April 25, 2025.I swap out the board and to my dismay the device is still broken. They have escalated it to their Senior Technical Personnel and I am now waiting on a resolution.Update #2They sent a replacement and I just received it this past weekend. Looking at the insides of the device, this one has different internal components than the one I originally received.

Not quite as high of frequency that i was hoping for. Works ok for jewelry, but could be a little better. It does heat up, but takes a minute to figure that out.

I got mine yesterday, 07/25/2023, and it works fine. I bought it to clean my bike chain only because I used to use Kerosene to do it and it smells bad and it is toxic so I decided to try an ultrasonic machine to eliminate that kerosine of my chain cleaning equation. It works fine. Chain comes out clean enough for me. It is not intuitive to use, example: there are TWO on/off buttons on the front panel, why?????? I pressed one only and it did not started, then I pressed both and it started!!!! Why two on/off buttons????? I used the machined 4 times because if you use the basket that is included, it does not do a good job. Just don't used that basket. Put your stuff in the machine without the basket ant it will do a good job cleaning it. Max temperature is 80 degrees Celsius only. I needed more than that. I needed at least something close to 100 degrees Celsius and that is why I had to used the machine 4 times to get that chain clean enough. I wax my chain and very hot water is needed to melt the old wax mixed with dirt from past rides. Just set it up to 15 minutes and 80 degrees Celsius and used it twice to get a good cleaning of the chain (put hot water from the tap inside it to begin with), it helps a lot). Otherwise, it works great! I hope it does not stop working suddenly as it happened to some people who reported it. I will let you know if its happens. In a nutshell, It works great, not awesome cleaning, but good enough! For the price I paid, it is a good deal. To finalize I would recommend you to read the instructions carefully because it tells you what NOT to do in order to NOT break it yourself. You can not drain the water immediately after it is finished cleaning for example, you can not turn it on and put water after it and so on... Just don't do what they tell you not to and the machine will last I think... Thanks and have a nice day!
