Please be aware that the following scenarios may affect the positioning of the machine and cause overlapping maps:

1. Confirm if the station is placed correctly against the wall, it is also recommended to have at least 1.6ft of space on either side of the station and 4.9ft of space in front of it with no obstacles. Please note that placing the Auto-Clean Station in a long corridor can also affect the robot vacuum's mapping and positioning as it will not be able to recognize its location without detecting reference points in its current surroundings.
2. Check if the robot vacuum has been manually picked up and moved to another location during its cleaning cycle.
3. Please note that strong direct lighting or mirror reflections in the home environment can cause mapping errors.
4. If there are any obstacles such as thresholds, bar stools, carpets, or Barcelona chairs in the house, the robot vacuum's wheels may slip and cause overlapping maps.
5. Check if the furniture in the house has been rearranged, such as moving the sofa to another location in the house, placing a new dinning table, etc.
6. Ensure the robot vacuum has not been continuously interfered with by a pet or person during its cleaning cycle (for example, children or pets circle around the robot) for at least 30 seconds.
7. Check if the robot vacuum's wheels are stuck due to the wheels being entangled with power cables/or other objects.
8. If your home has two floors with similar layouts, the first-floor map and the second-floor map may merge together.
9. Inspect the side of the laser navigation scanning component for any dirt or stains. Make sure the robot vacuum's firmware version is the latest version to ensure its reliability and cleaning performance.
10.  If overlapping maps occur, please refer to the following picture to delete the maps that you do not need. There is a direct "Delete Map" button under the "Map Management" page for every map that has been created and saved.

If the issue still persists, please enable the "Log Upload" feature and run the robot vacuum several times. Please note that uploading your log will better assist eufy product engineers to analyze and locate the root cause of the issue.
