Invent a Self-Destructing DNA Vacuum for Thieves

Imagine you're a cat burglar or mob hitman. You commit a crime but you don't want to leave behind any DNA.

Pull out a DNA Vacuum device, flip the switch, toss it on the floor and walk out.

The device vacuums violently in all directions and then incinerates itself.

This avoids the huge mess and collateral damage/victims from fires.

The crime was gonna happen anyways, might as well not kill the old lady next door with a fire.
