3.1 Unpacking and Initial Placement

1. Remove all packaging materials and protective films from the robot and charging dock.
2. Place the charging dock against a wall in an open area, ensuring there are no obstacles within 1 meter (3 feet) to the sides and 2 meters (6 feet) in front of the dock. This ensures the robot can easily find its way back to charge.
3. Connect the power adapter to the charging dock and plug it into a wall outlet. Ensure the power cord is neatly arranged to prevent tangling.

3.2 Installing Side Brushes

• Turn the robot over.
• Align the side brushes with the corresponding posts (L and R) on the bottom of the robot and press them down until they click into place.

3.3 Initial Charging

• Place the robot onto the charging dock. Ensure the charging contacts on the robot align with those on the dock.
• The robot will begin charging automatically. For first-time use, fully charge the robot (approximately 4-5 hours) before its initial cleaning cycle.

3.4 App Installation and Connection

1. Download the 'Lefant' app from your smartphone's app store (iOS or Android).
2. Open the app and create an account.
3. Follow the in-app instructions to add your M310 Ultra robot. This typically involves turning on the robot, entering your 2.4GHz Wi-Fi network details, and pairing the device via Bluetooth.

4. Operating Instructions

4.1 Cleaning Modes

4.2 Navigation and Obstacle Avoidance

The M310 Ultra utilizes advanced navigation technologies:

• ToF Laser Mapping: Creates a 360° instant room map for efficient and full-coverage cleaning, ensuring no spots are missed.
• 190° PSD Obstacle Avoidance: Precision-sensing technology with a wide detection range to easily maneuver around furniture, toys, and other obstacles, preventing collisions.
• Day & Night Obstacle Detection: Ensures collision-free cleaning in various lighting conditions.

5. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your M310 Ultra.

5.1 Dustbin Emptying and Cleaning

• The 500ml high-capacity dustbin typically requires weekly emptying, depending on usage.
• To empty: Open the top cover of the robot, remove the dustbin, and discard collected debris.
• To clean: Rinse the dustbin with water (ensure it's completely dry before re-installing). Clean the HEPA filter by tapping it gently to remove dust or rinsing it if it's washable (check filter type for specific instructions).

5.2 Water Tank and Mop Cloth Cleaning

• After each mopping session, remove the water tank and empty any remaining water.
• Rinse the water tank thoroughly.
• Remove the mop cloth, rinse it, and allow it to air dry completely before reattaching.

5.3 Side Brush Cleaning

• Periodically check the side brushes for tangled hair or debris.
• Carefully remove any tangled hair or debris using a cleaning tool or scissors.
• If brushes are worn, replace them with new ones.

5.4 Sensor Cleaning

• Wipe the ToF laser sensor, PSD sensors, and cliff sensors with a clean, dry cloth to ensure accurate navigation and obstacle detection.

6. Troubleshooting

If you encounter issues with your M310 Ultra, please refer to the following common solutions:

• Robot not charging: Ensure the charging dock is powered on and the robot's charging contacts are properly aligned with the dock. Clean the charging contacts on both the robot and the dock.
• Robot gets stuck frequently: Clear obstacles from the cleaning path. Ensure the PSD sensors are clean. Check if the robot is trying to climb over objects too high for its clearance (7.9 cm).
• Poor cleaning performance: Empty the dustbin and clean the filter. Check and clean the side brushes for tangled hair. Ensure the suction mode is set appropriately (e.g., Max mode for heavy debris).
• Mopping is ineffective: Ensure the water tank is filled and properly installed. Check if the mop cloth is clean and correctly attached.
• App connectivity issues: Ensure your Wi-Fi network is 2.4GHz. Restart your router, the robot, and your smartphone. Re-pair the device in the Lefant app if necessary.
• Robot makes unusual noises: Check for any foreign objects caught in the side brushes or wheels. Clean the dustbin and filter.

For persistent issues, please contact Lefant customer support.
