If your E25/E28 robot is repeating cleaning tasks or overlapping its cleaning paths, please try the following troubleshooting steps:

• Please check if the "Stain Cleaning" feature is enabled. When this feature is activated, the E25/E28 robot will perform a double-cycle deep cleaning procedure upon sensing floor stains such as coffee spills.

• If the E25/E28 robot performs localized cleaning again in a room that has previously been cleaned, it is likely because the "Re-sweep Logic" feature has been activated. The E25/E28 robot automatically detects areas that were not completely cleaned in the previous cycle and returns to perform additional cleaning in those spots.

• Recurring cleaning paths observed near obstacles may stem from the E25/E28 robot's obstacle avoidance mechanism.

If you have any other questions about the E25/E28 robot, please don't hesitate to contact eufy Support Engineers for further assistance.
