5.2 ToF Navigation and Obstacle Avoidance
The M310 Ultra utilizes advanced ToF (Time-of-Flight) laser navigation for precise mapping and efficient cleaning paths. Its exclusive PSD (Position Sensitive Detector) obstacle avoidance technology, with 9 sets of triangular front sensors, accurately measures distances and avoids obstacles within a 180° detection field, even thin table and chair legs.

5.3 Carpet Detection and Suction Adjustment
The M310 Ultra features infrared technology for instant carpet detection. When a carpet is detected, the suction power automatically increases by 200% for deeper cleaning. For mopping, intelligent anti-carpet sensors prevent the mop from passing over carpets. If necessary, place a carpet in restricted areas or attach the mop tray to the robot vacuum.
