3.2L Ultrasonic Cleaner

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!

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!

Bought this to upgrade from the smaller, plastic ones I've had in the past. It is a much better machine than those, and the price was good. No leaks, fits a lot of items so you're more efficient/less likely to waste solution. I do wish it had a proper drain, but I think that's limited to the largest offerings. It's also very noisy, and a rather unpleasant noise at that, but for the cost and results it gives I'm not unhappy at all.

Holds a decent amount, loud but not too loud, and wow does a great job with the right solution.

This is a great ultrasonic cleaner! Gets the job done well.

This is my first ultrasonic cleaner and I’m pleasantly surprised my the results. It’s able to really easily clean my glasses and my watch. It gets to work in seconds and it’s easy to set up. It runs fairly quietly and has plenty of room in the basket!

Worked great on cleaning my suppressor baffles that were covered in gunpowder and soot. Used with Purple Power and they came out shiny! A little noisy but not bad.
