Let a robot clean your floor.
The iRobot Roomba 440 vacuum and counter rotating brushes reach deep into your carpet to remove dust, dirt and pet hair. This entry level robotic floorvac is easy to use and includes an array of convenient features. Simply press the clean button and the iRobot Roomba will vacuum the whole floor, adjusting automatically to any floor surface including wood, tile, linoleum, and low to medium pile carpet.
The Roomba is small enough to go under furniture which no upright can do. This robot 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 infrared cliff sensors in the non-marring bumper detect stairs to keep the unit from falling.
