I have an ultrasound cleaner and it definitely vibrates and is noisy.

I think that's just a sound cleaner.

Every ultrasound device makes sound, sometimes a lot of sound, because it's vibrating all of the materials, liquids, and air around it.

So does every piece of baryonic matter in the universe, in which case I am proud to be an ultrasound device.

Affirming the consequent fallacy.

"Ultrasound machines vibrate everything around them therefore make sound" does not imply "I vibrate everything around me therefore make ultrasound."

Applause for the pun.

When working with ultrasound, I think of it the context of a micro-agitator versus the large scale shaking, snipping, and slapping clothes against rocks methods.

but that could be fixed by isolating the device from the environment, the ultrasound would not be heard, unless you're a bat.
