Lymow Mapping Problem: Fix Failed or Inaccurate Lawn Maps
A Lymow mapping problem may appear as a failed save, drifting boundary, missing area, overlap, or route that cannot be completed. Because Lymow combines RTK and visual positioning, both signal quality and what the mower can see matter.

Quick answer
Map in dry daylight, confirm stable positioning and app connection, drive the boundary slowly, and leave extra clearance around walls, water, drop-offs, trees, and narrow passages. Test a small zone first.

Fix it in this order
- Start with a small test zone
Create a simple open area near the charging station before mapping the entire property. - Confirm positioning and app status
Resolve any weak-positioning or offline warning before starting. - Use clear conditions
Map in daylight with dry lenses, visible lawn edges, and grass short enough to reveal the boundary. - Drive slowly and smoothly
Avoid sudden steering corrections and leave a conservative margin beside hazards. - Simplify narrow passages
Use wide, direct channels and gentle turns between zones. - Inspect exclusions
Make sure no-go zones do not overlap or block a required route. - Save and supervise
Wait for the map to sync, then watch the first short run.
What usually causes this?
Weak positioning, interrupted phone connection, poor camera visibility, tight passages, overlapping boundaries, a moved station, or an incomplete app or firmware update are common causes.
How to verify the fix
The map should reopen with the same alignment and the mower should complete a short supervised edge and mowing test without crossing exclusions.
Do not skip this check: a cleared warning is not proof of a repair. Confirm the mower completes the affected action under supervision before restoring unattended schedules.
Frequently asked questions
Should I delete the map first?
No. Fix power, connectivity, positioning, and hardware placement first. Remapping can hide the original cause.
Should I install an update?
Install only an official update offered for your exact model and keep power and connectivity stable.
When should I stop?
Stop for damaged wiring, unusual heat, battery swelling, burning odor, water inside electrical parts, or repeated hardware faults.
When to contact support
Contact Lymow if a simple open test zone cannot be saved. Include screenshots, RTK status, station photos, model, app and firmware versions, and a screen recording.
