Operating Instructions
1. 3-in-1 Cleaning Modes
The M2 Plus offers vacuuming, mopping, and sweeping functionalities simultaneously. It features a powerful 6000Pa suction to effectively pick up debris, hair, and dust from various floor types and carpets. The detachable mop holder allows for flexible cleaning options.

2. Advanced Navigation and Mapping
The M2 Plus utilizes 360° LiDAR precision navigation with a 15-meter scanning range to create accurate maps of your home. This allows for efficient and systematic cleaning paths, adapting to complex layouts and multi-level homes (up to 3 floors).

3. Precise Obstacle Avoidance
Equipped with dToF navigation and 190° omnidirectional PSD obstacle avoidance, the M2 Plus quickly maps and plans precise cleaning paths. Its Freemove full-body detection technology ensures smooth maneuvering around obstacles, preventing collisions and protecting your furniture.

4. Automatic Carpet Detection and Boost
The M2 Plus features advanced carpet detection. When the mop holder is attached, it intelligently avoids carpets to keep them dry. When the mop holder is removed, it automatically increases suction to maximum (6000Pa) for deep cleaning on carpets.

6. 75-Day Auto-Emptying Station
The M2 Plus comes with an auto-empty station that automatically transfers collected debris from the robot's dustbin into a larger 2.5L dust bag. This allows for up to 75 days of hands-free cleaning, significantly reducing the frequency of manual dustbin emptying.

7. Long Battery Life and Auto-Resume
With an upgraded battery, the M2 Plus can operate for up to 140 minutes, covering an area of up to 140 m². If the battery runs low during a cleaning cycle, the robot will automatically return to its charging station and resume cleaning from where it left off once sufficiently recharged.
