2. Setup and Installation
The Base Support is a replacement part. Installation typically involves removing the old or damaged support and attaching the new one. Ensure your robot vacuum cleaner is powered off and disconnected from its charging base before proceeding.
- Power Off: Turn off your Lefant M3 or M3L robot vacuum cleaner and remove it from the charging station.
- Access the Base: Carefully flip the robot vacuum cleaner over to access its underside.
- Remove Old Support (if applicable): Identify the existing base support. Depending on the model, it may be held in place by screws or snap-fit clips. Use an appropriate screwdriver if screws are present, or gently unclip the old support.
- Install New Support: Align the new Base Support with the corresponding slots or screw holes on the robot's underside.
- If screw-mounted, secure the new support with the original screws. Do not overtighten.
- If snap-fit, press firmly until the support clicks securely into place.
- Verify Installation: Gently shake the robot to ensure the new base support is firmly attached and does not wobble.

3. Operating Instructions
The Base Support is a passive structural component of your robot vacuum cleaner. Once correctly installed, it requires no further operational input. Its function is to provide structural integrity and proper spacing for other components on the underside of the robot. The robot vacuum cleaner operates as usual after the base support is installed.
4. Maintenance
To ensure the longevity and proper function of your robot vacuum cleaner, periodic maintenance of the Base Support is recommended:
- Cleaning: Periodically inspect the base support for accumulated dust, hair, or debris. Use a soft, dry cloth or a small brush to clean the surface. Avoid using harsh chemicals or abrasive materials.
- Inspection: Check the base support for any signs of cracks, damage, or loose connections. If any damage is observed, consider replacing the part to prevent further issues with the robot vacuum.
5. Troubleshooting
- Part Does Not Fit:
Ensure you have purchased the correct base support for your specific Lefant model (M3 or M3L). This part is not universally compatible with all Lefant models (e.g., M3 Max may require a different part).
- Base Support is Loose After Installation:
Re-check all attachment points (screws or clips) to ensure they are properly secured. If the part is still loose, it may be incorrectly aligned or damaged. Re-installation may be necessary.
- Part Breaks Soon After Installation:
Inspect for any external impact or improper installation. If the part appears defective, contact the seller for assistance.
