$249.99 for iRobot Roomba 560 Vacuum Cleaner (Refurbished) ($474.99 List Price)

The folks at iRobot were able to completely revolutionize household cleaning by contemplating the vacuum cleaner and removing its most awkward component—the human pushing it around. Without the need for a long handle, iRobot’s Roomba 560 is able to pack a powerful vacuum and counter-rotating brushes in a tiny package that sits no higher off the ground than a snoozing puppy, navigating under furniture and into tight corners to banish debris. All this cleaning equipment is powered by the Roomba’s advanced robotic brain, which guides the unit through rooms and over carpets and hardwood or tile floors. And when the built-in battery pack needs a recharge, the unit automatically returns to its included charging station for an energy-replenishing nap.
