First, let’s check if it's an issue with the installation. Check if there’s any excess water flowing from the installation point when you repeatedly remove and replace the tank. Ensure the clean water tank is not removed when it contains water to prevent any leakage. If the water tank is leaking, it might be due to a damaged part. In this case, we need to replace the clean water tank. Please contact us at USsupport@uwanttech.com to request a replacement clean water tank.
First, make sure the dirty water tank lid is properly installed. Reinstall the dirty waterIf the dirty water tank is tilted, lift it straight up to prevent leakage tank lid and ensure it's secured.

Adjust the cleaning solution ratio and discard any excess dirty water. If the issue persists, don’t hesitate to reach out to us at USsupport@uwanttech.com.
