"The Perfect Gift: Roomba Robotic Vacuum, Only $179.99"
The vacuum's artificial intelligence determines the room size and adjusts the run time to ensure that it cleans the entire floor. Integrated sensors detect dirt and will increase the focus and intensity of cleaning in that area, while infra-red cliff sensors in the non-marring bumper detect stairs to keep the unit from falling, as well as furniture and walls for cleaning right up to the edge.
