If your E25/E28 robot is leaving water stains after mopping, please try the following troubleshooting steps:

• Be aware that setting the water level to "Low" in the eufy app while mopping may lead to inconsistent wetting on uneven surfaces. It is recommended to select a suitable water level based on the specific type of flooring.

• If you notice uneven water streaks or missed areas while mopping, please start a self-cleaning and self-drying cycle for the roller mop using the eufy app. For future mopping tasks, it is recommended to increase the water level setting to a higher level.
