If the Xiaomi Robot Vacuum 6 Pro prompts that the dirty water tank is abnormal, please refer to the following troubleshooting steps:
1. Remove the dirty water tank and check if the sealing ring is deformed, warped, or not properly plugged in. If so, re-seal the ring before use.
2. After confirming that there are no abnormalities in the dirty water tank, buckle the dirty water tank cover, replace it, and gently press it to ensure that the dirty water tank is installed to the bottom.
3. Please check whether the dirty water tank is full. After emptying the wastewater, reinstall it.
4. If the problem persists, please contact the after-sales service center for inspection.
