iRobot was founded in 1990 when Massachusetts Institute of Technology roboticists Colin Angle and Helen Greiner teamed up with their professor Dr. Rodney Brooks with the vision of making practical robots a reality. The company offers consumer products, such as floor vacuuming robots, floor washing robots, pool cleaning robots, gutter cleaning robots, and programmable robots. It sells its robots through chain stores and other national retailers, as well as through its on-line store to consumers, the U.S. military, and other government agencies worldwide. More than 10 million home robots have been sold worldwide, with the award-winning iRobot Roomba floor vacuuming robot leading the charge.
