A “Roomba” is a robotic vacuum cleaner made by iRobot. We received one this morning from our youngest son and it was an immediate hit. We put it (him? her?) to work cleaning up cracker crumbs and pine needles in the living room, and began brainstorming  YouTube possibilities, only to find out (of course!) that others had beat us to it. Check out “Roomba Robots Fighting”:
