Narwal T10 is a new mop and vacuum robot featuring innovative self-cleaning technology. The robot is able to return to the base station for mop cleaning automatically and to resume work from the spot where it had paused. In order to achieve the goal of deep cleaning, the rotating and down-force technology highly enhances the cleaning efficiency. Narwal T10 can learn the environment with the technologies of Lidar Navigation and Simultaneous Localization and Mapping (SLAM).
