A. The Roomba s9+ robot vacuum’s superior suction power combines with PerfectEdge Technology for our deepest clean yet*. With a unique Maximised-Edge Design, advanced sensors, and a corner brush specially designed with 5 angled arms, the robot grabs dirt and debris from deep in corners and along walls, directing it into the robot’s path to be vacuumed up. The 3-Stage Cleaning System uses Dual Multi-Surface Rubber Brushes that instantly adjust and flex to help thoroughly clean carpets and hard floors, and 40X the suction* to pull in embedded dirt, debris and pet hair from wherever it hides.
