Answer:
Hardware factors
- Dull or damaged blades — Replace the blades if they’re worn, bent, or no longer sharp.
- Blade disc rotation — Ensure the blade disc spins freely. Clear away any grass clippings or debris stuck around or under the blade disc.
- Blade and deck condition — Inspect blades for nicks, excessive wear, or corrosion. Also check that the blade deck is intact and undamaged.
- Upper body cover installation — Make sure the mower’s top cover is fully and correctly installed. If it’s misaligned or loose, the binocular camera may misidentify obstacles — which can reduce cutting accuracy.
Software factors
- Uncut area location — Check whether the missed area is near the edge of your map. If so, confirm that Edge cutting mode is enabled in your app settings.
- Cutting height changes — Avoid adjusting the cutting height mid-task. Inconsistent height settings can lead to uneven or missed cuts.
- Mowing angle variation — In your next mowing task, try changing the mowing direction (e.g., from north–south to east–west) and observe whether the issue improves. This helps identify if orientation affects coverage.
- RTK models only — Verify that your RTK signal is strong and stable. Weak or intermittent signals can affect positioning accuracy.
- LiDAR models only — Ensure the LiDAR module is clean, unobstructed, and free of scratches or dirt. A dirty or damaged sensor may impair navigation.
- Manual touch-up — Use the Remote Control feature in the app to guide the mower manually and cut any remaining uncut sections.
Environmental factors
- Lawn size and schedule — If your lawn is large, the current mowing time or frequency may be insufficient. Try increasing either (or both) to ensure full coverage.
- Obstacles in the mowing area — Remove visible objects like toys, garden tools, or low-lying branches. Also inspect the uncut areas closely — sometimes small or low-profile obstacles (not visible in the app) may be blocking the mower physically.

Grass height — Very tall grass may exceed the mower’s maximum cutting capacity. For guidance on height limits and performance with tall grass or weeds, see:
Question: How good is the mowing performance? Can it handle tall grass or weeds? - Grass density — Extremely thick or dense grass can overwhelm the mower’s cutting ability, leading to incomplete coverage. Consider mowing more frequently to prevent buildup.
- Slopes and uneven terrain — Missed areas on inclines or bumpy ground may result from wheel slippage or reduced traction. Check if the mower struggles to maintain consistent contact with the surface.
- RTK antenna and weather impact — Confirm the RTK antenna hasn’t been moved or obstructed during operation. Also note that heavy rain, fog, or strong electromagnetic interference can weaken the RTK signal — causing positioning errors and missed cuts.
