There's a new robotic vacuum cleaner coming from Hanool Robotics that the company claims will be smarter and better at cleaning rooms than the Roomba and the other robovacs that are out now. Instead of moving around a room randomly, or in ever-expanding concentric circles (like the Roomba), the OTTORO uses cameras and sensors to plot out the most efficient route for vacuuming a room. Also improving on the Roomba, the OTTORO can clean corners using a special section port and automatically return to its base station for charging.
