We own a small engine repair shop and purchased the 15L for carburetors and other parts. This unit works so well, we plan on purchasing a smaller one for 2cycle carbs and smaller jobs. The unit is relatively quiet, and the large touch is very easy to control. It heats very well, and is quite insulated. After shutting the unit off, the water is still in the 90’s the next day! (as long as you put the lid on.). The temperature is accurate, and within 1 degree. (Checked and monitored with our Fluke thermometer.) Once the temperature is reached, the heater shuts off and turns back on as necessary to keep it at the desired setting. We found that the water usually only gets hotter as you run the unit from the heat of the electronics or perhaps the ultrasonic effects? But usually increases a degree or two. It has a cooling fan in the bottom as the electronics do generate some heat. We have put several carburetors through the unit so far, and we are impressed! The pictured carburetor is off of a snowblower and hadn’t been used in several seasons. After a 30 minute cycle of full wave, and an additional 10 minute on sweep, with water temperature at 150C, the results are impressive! Whats even more impressive? We have been using just water! We did try another carb with some dawn dish soap to experiment, but results have been remarkable. As another experiment, we took some air filters from Husqvarna chainsaws and put them through the half wave cycle. After just 5 minutes those things came out looking like new! We have also done a couple spark arrestor screens, and even tried a fowled spark plug. It actually done really well. As for the longevity of this unit, time will tell. But it does seem built quite well, and comes packaged very well also. So far we are impressed, and the unit is paying for itself. Read more

Overall, the USC works great. Used it on a dirty BCG, and the amount of carbon that came off was incredible. Recommend using a 50/50 solution of simple green and water, and degassing before starting the cleaning. Did an hour of mixed wave at 52 deg C (~125 deg F). Then removed the parts ans set them on a paper towel to drain/dry; the heat makes all the fluid set off, and you will need to re-oil the parts, especially the extractor. When the solution was all cooled off, I drained the solution into an empty container filtering it through a coffee filter. The solution can then be used again...don’t know how many times, but I’m guessing a few BCG’s worth. Why the 4 stars instead of 5, you ask? Because the thread on the brass part that needs to be screwed into the drain ball valve was messed up and I had to file it and straighten it so it would actually thread in. Also, the hose clamp for the included hose was typical CC (Chinese Crap), and the hose leaked. Had to buy a better hose clamp at Harbor Freight and tighten it well and the problem was solved. Other than that, we’ll see how long it lasts. It does wit well and albeit the issue encountered with the drain parts, it does represent good value. Read more
This little guy is pretty impressive. I like that you can heat the tank before starting the cleaning cycle, it really makes a difference in cleaning effectiveness. Three different cleaning modes seem to tear through dirt and buildup. I primarily use it to clean firearms and parts, it does a great job of unlocking carbon locked parts, breaking up deposits on suppressors, etc. Some scrubbing/scrapping is still required after cleaning cycle, but for the most part, it does a great job. This particular model does not have a drain. I can definitely see how that would make things easier when it comes to emptying the tank to switch between solutions and avoid potential water damage to the unit while doing so. It’s not quiet. It’s also not horrific. It does make my hearing aid freak out though. Overall, I’d probably go up a model to get the drain, but I would recommend this brand. Read more
Purchased July. 24, 2024. Used it one time to clean carb for lawn mower. Worked great. Cleaned it up and put away until week ago. Pulled it out to clean another carb for generator. Ran 15 minute cycle on full wave and carb wasn't clean. Ran 15 minute cycle on pulse carb still not completely clean. Floated a sheet of aluminum foil on the water and it showed that the only place the ultrasonic waves were in a small 2 inch x 1 inch area near a corner. Eventhough there were ripples on the water surface they were not the ultra sonic waves needed for cleaning. there were no cavitation bubbles hitting the surface to be cleaned. VERY DISAPPOINTED. Tried all modes.. No joy. Read more
The DK Sonic 600PF 6 Liter ultrasonic cleaner has made a very good first impression. Although considerably more expensive than my old "blue label" 6 liter ultrasonic cleaner, it is a much better cleaner. In comparison to my previous one which was half the cost, the DK Sonic sits taller, has Degas, Sweep and two power modes, where the old one is merely "ON" and "OFF". In addition, the DK Sonic has a cooling fan for the electronics for longer cleaning sessions and has a far more effective heater and much better cleaning action, while being considerably quieter. A test of the current draw shows that the DK Sonic is honestly rated, with both the heater and the ultrasonics drawing the advertised amount of wattage, whereas the old unit was considerably less than advertised. As the old one did, the DK Sonic has three transducers. The touch controls take a little getting used to but work well. The display is large and bright and can be seen from a fair distance. In summary, so far the DK Sonic 600PF appears to be well worth the additional expense over the cheaper models. Read more
