Our friends at iRobot have shrunken its hardwood cleaning child -- not Roomba, the other one -- to about half the diameter of its predecessors (6.5 inches). The Scooba 230 is maintains the same 3.5-inch height and, more importantly, is just as programmable as every other model (in an unfortunate twist of irony, it's now thinner than a Kinect sensor). Speaking of Roomba, the company's also unveiling the new 700 series with a number of cleaning and detection improvements. All autonomous cleaning discs will be available in the Sprint from iRobot's online store with the prices ranging from a penny under $300 for Scooba 230 and $450 / $500 / $550 for the Roomba 760, 770, and 780. More shots / hands-on below; full details in the press release after the break.
