If the Xiaomi Robot Vacuum 6 prompts that the dirty water tank is abnormal, please refer to the following troubleshooting steps:
1. Please check whether the dirty water tank is full. After emptying the dirty water, reinstall it.
2. Remove the dirty water tank and check whether the sealing ring is deformed, warped, or not properly seated. If so, reseat the sealing ring and try again.
3. 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.
4. If the problem persists, please contact the after-sales service center for inspection.
