Granbo Ultrasonic Cleaner 4.5L

The Granbo ultrasonic cleaner combines a 4.5L stainless-steel tank with a heater, timer, and degas mode, giving you several controls for cleaning small items without hand-scrubbing each surface. Its 40kHz operation and three ultrasonic transducers are intended to reach crevices and blind holes, while the digital panel lets you set a cleaning time from 0 to 30 minutes and a temperature from 0 to 80°C. That setup may suit a workshop or bench where jewelry, eyeglasses, small metal parts, or other listed items need regular cleaning. One practical boundary: the tank dimensions are 11.8 × 5.9 × 3.9 inches, so larger pieces won’t fit just because the stated capacity is 4.5L.

What matters most

This is a heated, timer-controlled ultrasonic cleaner, rather than a basic tub with a single on/off switch. The 180W ultrasonic system is paired with a 300W heater, and the degas mode is designed to remove gas from the liquid before cleaning. Those controls give you more ways to manage a cleaning cycle, but the listing does not specify cleaning results for every material or item. Keep in mind that jewelry, watches, circuit boards, and other delicate pieces can have different immersion requirements, check whether an item is suitable for this cleaning method before putting it in the tank.

The tank is made from 304 stainless steel, and four rubber feet are intended to keep the unit stable during operation. It runs on 110V. Compared with a smaller, simpler cleaner, the Granbo offers more capacity and adjustable heat, compared with a larger industrial setup, its listed tank dimensions put it firmly in the small-parts category.

How to use it

Add the cleaning liquid, place suitable items in the included basket, and use the digital controls to select a time and temperature within the stated ranges. For example, you could set eyeglasses or a handful of small parts in the basket, start a cycle, and let the machine work while you prepare the next task. The removable power cord and included manual are useful practical details for setup, though the product information does not name a specific cleaning solution or provide item-by-item settings. The degas function is another available control, but there are no instructions here on when to use it for particular materials.

Practical tips

Think about the objects you clean most often before choosing this model. The basket and tank format are suited to batches of smaller items, not long or bulky components. Measure anything you plan to clean against the tank’s 11.8 × 5.9 × 3.9-inch interior dimensions, and leave room to place it in the basket. The machine is described for uses including dental and lab work, electronics workshops, jewelry, glasses, and small metal parts, that broad list is not a guarantee that every item in those categories can be immersed safely.

It makes sense if you want heat, a timer, and degassing in one 4.5L unit for recurring small-item cleaning. Not the best choice if your main need is cleaning oversized parts or if you want clear, item-specific guidance on solutions and cycle settings. From the way it is set up, this is a control-rich bench cleaner, but you’ll need to make the material-suitability decisions yourself.

Before you decide

What comes in the box? The listed package includes the ultrasonic cleaner, a cleaning basket, a detachable power cord, and a user manual.

What controls does it offer? The digital panel adjusts the timer from 0 to 30 minutes and the temperature from 0 to 80°C, a degas mode is also listed.

Will a large part fit? Check its dimensions against the stated tank size of 11.8 × 5.9 × 3.9 inches. The 4.5L capacity alone does not confirm that a particular shape will fit.

Should you buy it?

Choose the Granbo if your routine involves small items and you value adjustable heat, timed cycles, and a degas setting in a 4.5L stainless-steel tank. It offers more control than a basic, unheated cleaner, while avoiding the footprint implied by a much larger parts-washing setup. Skip it if the items you handle exceed the tank dimensions or need confirmed cleaning instructions that the listing does not provide. Before committing, make sure the 110V power and compact tank suit your workspace and the objects you actually plan to clean.
