When was the Roomba introduced? Roomba was introduced in September 2002. As of February 2014, over 10 million units have been sold worldwide. Roomba features a set of basic sensors that enable it to perform its tasks. For instance, the Roomba is able to change direction upon encountering obstacles, to detect dirty spots on the floor, and to sense steep drops to keep it from falling down stairs. It uses two independently operating wheels that allow 360° turns in place. Additionally, it can adapt to perform other more creative tasks using an embedded computer in conjunction with the Roomba Open Interface.
