Coway’s Cleaning Device uses megasonic
This is a cleaning device that uses soundwaves to clean everything from perishables to non-perishables. It works on the theory of micro cavitation which looses dirt or contaminants from the surface of the object.
If this thing flies, we would never ever need water to clean ourselves anymore. Just stand in front of the megasonic gadget, an earplug and you’ll be bombastically cleaned. Btw, the Coway’s cleaning device gets a little loud if you’re too dirty - works on the same principle of mothers screeching when you walk on their carpet with muddy shoes.
