iRobot showcases Roomba Duo concept at IFA

iRobot showcased the Roomba Duo concept at the IFA trade show in Berlin. The main floor-washing unit navigates using lidar and cameras, its steam-mopping roller brush applies 46 newtons of downward pressure, and it carries a Roomba Plus 757 on top, which a robotic arm lowers to clean under tables and in corners. In the demo, the main unit picked pasta up from a carpet and cleaned the carpet. New CEO Hao Li introduced the machine; as a concept product it has no price or launch date, and its specifications are still in development.
