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

I bought this 6L capacity cleaner because I had a 3L before and it really wasn't big enough for anything but small very carburetors. The 6L can accommodate decent size carbs and I mean plural because you can clean 2 or 3 at once, depending on their size.That said, I did some measurements and the tub does not match the dimensions advertised, it comes in at 12.8"x5.9" at the top and is tapered toward the bottom with depth of 5.9". However, since it is not a perfect cuboid/block, it holds only 5.5L of liquid to the very top. The recommended fill line puts the useful capacity only at 4.5L. Now as for the basket, its measurements (averaged readings from both ends of each dimensions) come in at 25cm x 11.5cm x 8.8cm (for ease of calculating) which puts its volume at 2.5L.The supplied drain hose is nicely flexible and 30.75" long and it comes with a fitting to screw into the drain (ball) valve. Silly thing: while the drain valve utilizes the standard British NPT 3/8" threads, the plastic fitting has a metric pitch of 1.25mm/thread. (see picture)Having the drain valve on the unit is very useful given its capacity but once the tub is drained, it is best to dump any remaining few milliliters by flipping the cleaner upside down because the tub bottom is not sloped toward the drain and as such does not allow all the liquid to flow out perfectly .(see picture. Word of advice: it is best not to empty the tub perfectly by shaking every drop out (with the drain valve open) because only the tub is stainless, the drain is not. And it can rust after just one use. (see picture)I like the little stainless steel ball enclosure for small items but its size (just over an inch) does not allow too many items inside, maybe 1 ring or a few short screws or carb jets. I would have preferred a bigger one but since it was a nice extra surprise (not advertised in the listing), I am not complaining.The parts cleaner is powered by a 5ft standard grounded cord.The control panel is clearly labeled, allowing for operation without having the read the user manual every time. (Though the up/down buttons are reversed, as has become the norm with Chinese designs)The control panel digits are nicely bright to read even in direct sunlight and so are the ON indicators for the heater and sonic elements, even though that the indicators are visible only from a limited angle straight ahead. Buttons have a nice and crisp feeling and the panel beeps loudly with each press. The default temperature preset is 50°C and default (longest) time for cleaning is 30 minutes. It would be nice to see maybe 60, 90 or even 99 minutes. That would eliminate the necessity to have to come back and restart the cycle for another 1/2 hour.The heating element could be a little stronger, 50W takes a very long time to heat up a full load. Specifically, a tub full of water at room temperature takes a whole 1/2-hour cleaning cycle to get up to the default preset 50°C.As far as noise levels, they aren't high. Certainly louder than the 3L cleaner I had but acceptable and not really noticeable in a work shop with tools going. I like to hear the thing buzzing anyway because at least I know it's running. When it stops, even if I miss the two loud beeps, I will notice later that there is no noise and I know the parts are done.Overall, even though the advertised capacity is above the actual capacity, this cleaner can still accommodate plenty of parts.

I don't usually write reviews but on this product I feel one is warranted. I am a dyi home machinist, metal fabrication, welding, and automobile enthusiast. It seems like I am always trying to clean grease, oil, dirt, rust, or mill scale off of something. I was aware of ultrasonic cleaners but because of bad reviews I have never gotten one. Most of them are generic and don't even have a company name on them. The complaints were all the same. Very slow to heat up, if at all, and didn't clean very well. They all look the same except for Vevor. They put their name proudly displayed. Almost all the reviews on the Vevor were positive so I ordered a 15 liter model.I also ordered some Simple Green Pro HD concentrate mostly because it is supposed to be friendly to aluminum while the regular is not. It also said it could be used in Ultasonic Cleaners. It arrived much sooner that what the projected delivery date given when I placed the order. It was packaged very well and there was no damage.I was in the process of fabricating a project using hot rolled steel flat bar and square tubing. Hot rolled steel needs to have the mill scale removed before it can be tig welded and powder coated. Grinding or blasting it off takes a lot of time and grinding discs are expensive. I gave up using that process when I learned that a good overnight soaking in white vinegar will loosen the mill scale and any rust but you then need to rinse the pieces off in water and a little scrubbing with a Scotch Bright pad. It's a little messy but it works very well. I had my parts soaking in vinegar when the ultrasonic clearer arrived. I was originally going to rinse and scrub them as usual but then I wondered if the cleaner would remove the left over residue so into the cleaner they went with 3 gallons of tap water and 3 cups of the Simple Green. I set the temperature at 55c and the timer at 30 minutes. It actually heated up pretty quickly and a placed an electronic thermometer in to see if it would actually heat up to the set temperature.After a few minutes it not only reached 55c and shut the heater off but it continued to heat to 57c which I verified on the thermometer. After 30 minutes it turned off and I pulled out the parts. I had a big smile on my face because the mill scale and rust were completely gone and the metal was spotless ready for welding after a quick rinse. I went from hours cleaning scale, rust, and oil from metal parts to doing nothing. Welded them up and another bath in the cleaner which removed everything from the welding and then powder coating which turned out flawless.Next up some greasy, oily 30 year old vise grips which I now use as a clamp for welding and grinding. There was so much build up of crud in the adjusting screw I could hardly turn it. Put a couple of other messy pliers in the cleaner also and set for 20 minutes. Times up, took them out they were all spotless and the adjuster on the vise grips turns like it did when they were new.I can't say anything about the unnamed brand of cleaners but the Vevor worked beyond any expectations I had. If you do metal fabrication and are tired of cleaning smaller parts before welding I highly recommend trying this clearer. You can pretty much put anything you want in as a cleaner. On You Tube I saw some guys even use gasoline. I won't be trying that. I also saw one guy who puts the white vinegar in the machine. I'm going to try that next to see if I can reduce an overnight soaking down to just putting the metal in the cleaner with vinegar.

I bought this to help me clean all the small and medium sized engine parts for my Mazda rotary engine rebuild. The 15L will fit one rotor on its side. It take a bit to preheat and when the ultrasonic cleaner function is on, its pretty umm, sonic. After the cycle the heater stays on so you need to go turn that off after the cleaning is done. I've used this with Super Clean and Simple Green Pro HD (the purple one, aluminum safe). The drain works fine for me and doesn't leak, although the hose kinks pretty easily.Update: the heater seems to heat to 55-60C even when I turn it down or try to turn it off. It would be nice to have actual control instead of the illusion of it.

Decent sized, Intuitive controls, and is very effective. I use mine for stripping models of paint and it has a good track record so far. But I’d recommend using a degreaser for removing paint from plastic or metal. It’s sturdy and comes with a nice tea leaf cage for putting smaller items in it. It is loud, not the loudest but enough to bother many in the house. Zero leakage and look the part
