Two robots for pet owners and one for small offices were added to the popular iRobot Roomba robotic vacuum cleaner line today. The iRobot Roomba 532 Pet comes with a new Sweeper bin that holds more than three times as much debris as the debris compartment of the original vacuum bin. It is said to be able to do a better job collecting pet hair, kitty litter or dander. The main part of the robot is identical to the iRobot 530. The Roombe 532 Pet is available immediately for $349, and comes with two virtual walls and an extra set of brushes.
