Neato XV-11 Robot Vacuum
Meet the Roomba killer. The Neato XV-11 ($400) is the only robotic cleaner with a brain. Whereas the various Roomba models bounce, bump and bumble their way around your house aimlessly, the Neato bot uses onboard laser mapping (called the Room Positioning System) that lets it know the best cleaning path to take, quickly finishing one room and moving on to the next in a smart and efficient way. The sucking power is good, it lets you schedule automatic cleanings, and it automatically returns to its charging base like any good robot should.
