It's fitting that the Halo 3290 UV-ST Ultraviolet Vacuum ($500) shares a name with everyone's favorite space-age shoot-'em-up videogame: Employing UV-C technology -- the source of that hypnotizing blue glow at its business end -- the Halo kills dust mites, flea eggs, bacteria, viruses and other creepy-crawlies as it sucks the dirt out of your carpet. It also packs a HEPA filter to trap pollen and dust mites, as well as a 13-foot hose with tools for cleaning even the most neglected corners of your kids' rooms.
