iRobot is calling the latest Roomba its "most advanced robot yet," thanks to a number of new features to the 700 series that extend beyond the 790's redesigned faceplate. Chief amongst them is the Wireless Command Center, an oblong remote control useable from anywhere in the home that lets users steer the Roomba, send it back to its base, schedule a cleaning and adjust its clock. There's also a big "Clean" button, whose functionality seems fairly straight forward. Also on board with the 790 is room-to-room navigation, which utilizes "Virtual Wall Lighthouses." Roomba describes the feature thusly,
[A]djust to Lighthouse, set the distance of the door opening and place the Virtual Wall Lighthouse outside of the doorway to the room you want Roomba to clean. The Lighthouse will communicate with Roomba via an infrared sensor to contain it in one room until it vacuums the area completely (aka: completes its mission) and then it will move on to the next room and so forth.
The latest version of the cleaning machine is available today, for a suggested $700. Check out a peak of the aforementioned Command Center after the break.
