Ever wonder how much power your ginormous 70-inch TV consumes? Just plug a device into the Watt's Up Power Usage Meter ($130) and it instantly shows and records the wattage being used, plus other stats including average monthly cost. Watt's Up even has a "payback calculator" feature that automatically calculates the time required for an energy efficient appliance to pay for itself.
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.
