What to do if the Xiaomi Robot Vacuum S40 Pro doesn't dispense water during mopping?

If the Xiaomi Robot Vacuum S40 Pro doesn't dispense water during mopping, please refer to the following steps to troubleshoot:
  1. Make sure clean water is added to the water tank. Remove the water tank from the vacuum and fill it with clean water up to the designated fill line to ensure proper mopping performance.
  2. Confirm that the water tank is installed correctly. Reattach the water tank securely to the vacuum, making sure it clicks into place so water can flow properly during operation.
  3. Check that the outlet on the bottom of the water tank is not blocked.
  4. Restart the robot vacuum and try again.
  5. Use the Xiaomi Home App to ensure the vacuum has the latest firmware.
  6. If the above steps don't work, contact after-sales service for inspection and repair.
