iRobot Adds Wireless Command Center to New $700 Roomba Vacuum

IRobot, maker of defense and maritime robotics — it also makes the Roomba vacuum cleaner — has released a new vacuum as part of its Roomba 700 series. The Roomba 790 is an upgraded version of the 780, featuring a redesigned faceplate and a wireless remote that allows for room-to-room navigation. It costs $700 — $100 more than the Roomba 780, and about the same price as this hefty Oreck (non-robotic) vacuum.
