The Roomba is a housecleaning robot built by iRobot. It was the first robot ever built that is designed to live in your home, do something useful, and be priced for the mass market[1]. The Roomba is designed to vacuum a room without any help from a human or any other robot. The Roomba is controlled by heuristics that map the size of the room and the obstacles in its path.[1] The Roomba roams around the room and lightly bumps into other household objects.
      Although the Roomba is an intelligent machine and is the most advanced intelligent vacuum on the market it suffers from a few problems which limits its acceptance in the general public.Because of the Roomba’s circular shape, it cannot reach corners of the room, and leaves a little dirt in those corners. Also, if the couch, bed, or other piece of furniture is high enough, it has the possibility of getting stuck under it. After the Roomba covers the room many times, it beeps and shuts down. The Roomba costs $199, which is about the price of a mid-range vacuum cleaner. It is 5lb and 10oz, has limited vision, and is only 13.5 inches wide.
