Hi! I understand your Lefant M2 Plus mop vacuum isn't self-emptying as it should. Let's see if we can get this sorted out together.

First, could you tell me if the vacuum connects properly to its base station and if you've noticed any error lights or messages?

Meanwhile, here’s a step-by-step approach you can try:

1. Check the Dustbin Seal and Flap: Sometimes dust or debris can block the flap that releases dirt into the base's dustbin. Open the vacuum’s dustbin compartment and inspect the seal and flap for any visible dirt or damage.

2. Confirm Base Vacuum Motor Activation: When the vacuum docks and attempts to self-empty, the base station’s motor should activate, creating suction. Listen for any unusual silence or noises from the base. If it’s quiet, there might be a motor or power issue.

3. Reset Both Devices: Power-cycle the vacuum and the base station by unplugging the base and turning off the robot. Then turn them back on after 30 seconds. A reset can clear minor glitches.

4. Clean Brushes and Filters: Clogs in brushes or filters can reduce suction, affecting emptying performance. Give these a thorough clean.

5. Ensure Proper Docking: Make sure the robot is correctly aligned and firmly seated on the base station, as misalignment can prevent emptying.

If after these steps your Lefant still doesn't self-empty, the problem could be with the dock fan, sensor, or internal board.

Would you like me to guide you through checking these next, or perhaps suggest how to contact Lefant support if it seems like a hardware fault?

Are you comfortable trying these steps first?
