Woot is packing up their boxes and moving to a bigger facility and in their packing they found thousands of iRobot Roomba Discovery SE vacuuming robots that need a home. The Roomba is a dirt sweeping robot that can also be modded like crazy. The Discovery SE comes with all over the accessories like virtual walls, charging station, remote and more. It also retails for $299ish, so this is a pretty damn good deal for $150.
