We've heard of gadgets that can clean your laser, but until today we'd never heard of lasers that can clean your gadgets. We assume that laser cleaning works by burning off dirt layers, though laser cleaner companies tend to use phrases like "transform into thermal energy" when referring to what happens to the surface that is being cleaned.
The newest development in laser-cleaning technology is the backpack laser cleaner, the "first fully mobile cleaning laser unit in the world." It was designed to meet the "growing demand for a low-cost, portable cleaning laser" and can be used to remove paint, contaminants, and other residue in most industrial settings as well as in home renovations. The company neglects to mention that the backpack also makes cleaning cool, by turning its owners into laser-weilding ghostbusters.
