Now here's a cleaning device that will make a true germaphobe either squeal with delight or cringe with fear--or both. And it's not something you'll find in a Roomba or Scooba either.
Dirt Devil's "Purpose for Pets Portable Extractor" may have an unusually prosaic name, but it's probably preferable to a more graphic description of its mission: to locate carpet stains that are invisible or at least difficult to see. The system uses built-in LEDs to illuminate the offending spots so they can be detected "like you're wearing infrared goggles," according to Coolest-Gadgets. Once identified, it can be dispatched (one hopes) with the accompanying 3-inch scrub brush.
Come to think of it, though, the closest thing to a live pet that a real germaphobe might own would probably be a Tamagotchi.
