At the IFA tech show in Berlin, the original robot vacuum company, iRobot, unveiled a new concept robot called the Roomba Duo. This innovative device combines two cleaning units into one: a larger, heavy-duty floor washer and a smaller, more compact Roomba. Together, they work in tandem to clean different areas of a home. The larger unit handles sweeping and mopping on open spaces, while the smaller robot can maneuver into tight spots like under tables or in corners by lowering itself mechanically. The Roomba Duo is designed to be more than just a single robot—it’s essentially two robots in one. The smaller unit, called the Roomba Plus 757, sits on top of the main floor-washing unit and can detach and operate independently if needed. While iRobot demonstrated parts of the robot’s cleaning mechanism, the underside—where the actual mopping and sweeping take place—was not fully revealed during the presentation. The robot’s navigation system is located at the top, giving it a somewhat face-like appearance. This design helps it map out a home using lidar and camera-based technology, allowing it to navigate around obstacles and identify areas that need cleaning. The Duo also includes features like clean and dirty water tanks and a dust bag, making it a self-contained cleaning system that can operate autonomously. The Roomba Duo represents a significant step in the evolution of robotic cleaning technology, combining advanced navigation with dual cleaning capabilities. While it remains a concept for now, it highlights the ongoing innovation in home automation and the push toward more efficient and versatile robotic helpers.
