That could be the new Roomba wiping the floor with its competition. > iRobot's latest robotic vacuum, the $949 Roomba i7+ is by far its most ambitious yet. And with a price just shy of a cool grand, the i7+ is also the most expensive Roomba ever. This vacuum doesn't just clean floors on its own though, it empties itself too. In fact, the robot will deal with dirt it collects entirely by itself, for weeks.
