Halo Ultraviolet Vacuum

It is not a vacuum with Master Chief on it, but instead it is a Dyson vacuum that packs ultraviolet lights (UV) to zap bacteria on the floor and carpets. Obviously it also removes the dirt… The video on Amazon would have you think that dead bacteria, killed by the UV rays, is easier to vacuum than live bacteria. I didn’t see that one coming.

The UV lights should kill bacteria, but is this… “overkill”?
