4. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Lefant M350.
4.1 Self-Emptying Station and Dust Bag
- The self-emptying station automatically transfers collected dust from the robot to its 2.2L dust bag.
- The dust bag typically holds up to 40 days of debris, depending on usage and environment.
- Replace the dust bag when full. Dispose of the old bag and insert a new one into the station.

4.2 Robot Dustbin and Filter
- Even with the self-emptying station, periodically check and clean the robot's internal dustbin.
- The robot uses a HEPA filter. Clean the filter regularly by tapping out debris or using a small brush. Replace the HEPA filter every 3-6 months, or as needed.
4.3 Brushes and Wheels
- Remove and clean the side brushes and main brush (if applicable) regularly to remove tangled hair and debris.
- Wipe the driving wheels and universal wheel to ensure smooth movement.
4.4 Sensors and Charging Contacts
- Wipe all sensors (cliff sensors, obstacle avoidance sensors) on the robot with a clean, dry cloth.
- Clean the charging contacts on both the robot and the self-emptying station to ensure proper charging.
4.5 Mopping Pad
- After each mopping session, remove and clean the mopping pad. It can be hand-washed or machine-washed.
- Allow the mopping pad to air dry completely before reattaching.
5. Troubleshooting
- Robot not charging: Ensure the charging contacts on both the robot and the station are clean and free of debris. Verify the power cord is securely plugged in.
- Robot stuck or avoiding areas: Check for small obstacles or tangled wires. Clean the obstacle avoidance sensors. Ensure no-go zones are correctly set in the app.
- Poor suction performance: Empty the dustbin/replace the dust bag. Clean or replace the HEPA filter. Clear any blockages in the suction port or brushes.
- App connectivity issues: Ensure your phone is connected to a 2.4 GHz Wi-Fi network. Restart the robot and your router. Re-pair the robot with the app if necessary.
- Mopping not effective: Ensure the water tank is filled and the mopping pad is clean and properly attached. Check water flow settings in the app.
