Oh, an ultrasonic cleaner.

Lots of these at very low prices in China. Am considering importing one to use on my dirty-as-sin spectacles.

I need to get one of these.

Reader-added tags for now consist of "Acquisition of new technology" and "It can theoretically kill a person, by the way".

Ultrasonic cleaners, huh.
However many time had we tried them in 2000's, it seems they all turned out to be a scam.
Although they weren't box-like like one here in panel 1, but plug on one end of a 1-1.5m cord and a rectangular, spherical or pear-shaped object on another.
They were marketed to be portable laundry machines, but they did jackshit, even if it was only one handkerchief in the tub beside this device.

Because they were never designed to clean fabrics.

These are meant to dislodge dirt and grime from hard-to-reach places in small objects such as those tiny holes in metal watch bracelets, jewellery, gear teeth etc.

They're basically designed to "upgrade" a solvent; they help it penetrate deeper into stuck-on junk faster. I don't think they work very well with soaps in cases where you're cleaning something that isn't a hard smooth piece like a keycap, which require more of a brushing or rubbing action to clear detritus. I'm no sciencematician, though.

Mildly surprised nobody mentioned the Final Fantasy victory fanfare.
