Scooba

You've probably heard of the Roomba robotic vacuum, but you probably haven't met his brother, Scooba. Unlike Roomba, which sweeps carpet, Scooba ($400; available in November) washes and dries hard floor surfaces like wood, tile and linoleum. The compact robot is programmed to prep, wash, scrub, and dry floors in a single pass, and can clean in hard-to-reach places like under furniture. Scooba is also easy to use — just fill him up with Clorox cleaning solution, press clean, and empty his tank when he's finished doing your dirty work.
