Granbo 15L Industrial Sonic Cleaner 40kHz with Heater Timer and Degassing

I picked up the Granbo Ultrasonic Cleaner (800 mL) mainly for cleaning tiny watch parts and jewelry — and honestly it’s been a solid little helper. The tank size is perfect for rings, bracelets, tiny gears, and links without feeling overly big on my bench. The ultrasonic action noticeably loosened grime and oils in nooks that would’ve taken ages to clean by hand, and it left most items looking way fresher than a quick soak ever did.The digital timer and degassing mode are nice touches for controlling the cycles, and the stainless steel tank feels sturdy. It’s not super powerful compared to pro units (and doesn’t have built-in heating), but for what I use it for it gets the job done reliably. Just keep in mind ultrasonic machines are great for cleaning, not polishing — so don’t expect it to fix scratches or deep tarnish.Overall, good value for the price, especially if you want to skip scrubbing every tiny crevice yourself.

A Game-Changer for Cleaning!I've been using the Granbo Ultrasonic Machine 10L 240W for about a month now, and I have to say, it's exceeded all my expectations! As someone who tinkers with watches, jewelry. I needed a reliable cleaner that could handle a variety of items without damaging them. This machine delivers on every front.First off, the 10L capacity is perfect for larger batches – I can fit multiple pieces at once, saving me tons of time compared to smaller units I've tried. The 240W power combined with the 40kHz frequency creates powerful cavitation that blasts away dirt, grime, and residue effortlessly. I cleaned some heavily tarnished silver jewelry, and it came out sparkling like new after just a 10-minute cycle with the heater set to 60°C. The degassing function is a nice touch too; it removes air bubbles quickly, ensuring even cleaning from the start.The build quality is top-notch – the SUS304 stainless steel tank and basket feel sturdy and durable, and I don't worry about wear even after daily use. The digital controls are intuitive: adjustable timer, heater, and power settings make it easy to customize for delicate items or tough jobs. Plus, it's surprisingly quiet for such a powerful machine, which is great for my home workshop.Overall, this ultrasonic cleaner has made my hobby so much more enjoyable and efficient. If you're in the market for a professional-grade unit at an affordable price, the Granbo 10L 240W is a must-buy. Highly recommended!

Great size for cleaning, automotive parts, tools, well, anything you could actually fit inside of a 3.2 L tank. It’s insanely easy to use, seems durable enough, has a heater inside, and quality seems great! My only complaint is the fact that this is metric, but not a dealbreaker. Results are absolutely amazing too! No leaks either!

I’m very satisfied with this ultrasonic sterilizer. The durability feels excellent — the materials are solid and well made. The noise level is low, which is very important for a salon environment. The heat level is stable, and the temperature control works accurately, allowing safe and effective use.The cleaning power is impressive — it removes residue thoroughly, even from hard-to-reach areas. Overall, the functionality is great, easy to use, and reliable for daily professional work. Highly recommend!

It seems to be working as expected been using it for a couple months now to clean my rocks and it does an excellent job of getting all the grit at least 90% of the grit out really tough cracks are hard to hang out but this gets as much as possible

Works great for cleaning rocks for polishing.

Works well! Everything is in metric. I use it to clean my invasalign with water. I read the other reviews and started with hot water. Make sure you turn on the heater. It is very loud compared to a commercial one

I've had this unit a few months now and it has seen some pretty hard use. That said, I am impressed with it. It does a great job cleaning and the ultrasonic is nice and strong. I've taken it with me to other places to do work and it is easily transported when empty. The thisng is super durable and a gredat value considering what I paid for it on sale.
