Troubleshooting: Mower Crossed the Boundary Line

Overview

Under normal conditions, Neomow X operates strictly within the boundary you’ve defined during mapping.
If the mower moves outside the boundary area, it usually indicates a positioning issue. Below are the most common causes and solutions you can check.

✅ Possible Causes & Solutions

1️⃣ The charging station has been moved

If the charging station’s position is not the same as when the map was first created, the mower’s positioning may become inaccurate, causing it to drive beyond the boundary.

Solution:

• Delete the existing charging path

• Re-draw a new charging path to match the station’s current position

2️⃣ Water mist on the radar sensor

In humid or rainy weather, condensation or water mist on the radar sensor can interfere with boundary detection and localization accuracy.

Solution: Gently wipe the radar surface with a soft, dry cloth to remove any moisture

3️⃣ The radar protection cover is still on

If your mower is equipped with a radar protection cover, make sure it has been removed during normal operation.
The cover is only intended for protection during transport or storage — not during mowing.

Solution:

• Remove the radar protection cover

• Restart the mower and let it re-locate on the map

4️⃣ Significant Environmental Changes Near the Affected Area

If there have been major environmental changes around the area where the issue occurred — such as new or removed buildings, trees, or tall crops (like corn) — the mower’s positioning accuracy may be affected.

Solution:

1. Move the mower to an area where the surroundings remain unchanged and allow it to automatically re-locate; or simply return it to the charging station to help it re-establish positioning.

2. Edit the map and re-draw the boundary near the area where the environment has changed to ensure accurate mapping and mowing.

5️⃣ The Mowing Area Is Too Open or Featureless

In some cases, if the mowing area is too open or lacks distinct environmental features, the mower may have difficulty positioning itself accurately.

Solution:

1. Add some artificial landmarks (for example, small poles, signs, or other visible markers) to help the radar and vision system identify reference points.

2. Edit the map to adjust or re-draw the boundary lines near those markers to improve localization accuracy and stability.
