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 the blade disc or under the plate.
- Blade and deck condition — Inspect blades for nicks, excessive wear, or corrosion. Also check that the blade deck is intact, level, and free of dents or damage.
- Upper body cover installation — Make sure the top cover is fully and correctly installed. A misaligned or improperly seated cover can interfere with the binocular camera’s obstacle detection, leading to reduced cutting performance.
Software factors
- Uncut area location — Check whether the uncut area is near the edge or in the center of your map. If it’s near the edge, confirm that Edge cutting mode is enabled in your mowing plan.
- Cutting height consistency — Avoid adjusting the cutting height mid-task. Changing heights during mowing can cause uneven or missed cuts.
- Mowing angle variation — In your next mowing task, try changing the mowing direction and observe whether the issue improves—this helps identify orientation-related coverage gaps.
- RTK models only — Verify that your RTK signal is strong and stable. Weak or intermittent signals can reduce positioning accuracy and lead to missed areas.
- LiDAR models only — Ensure the LiDAR module is clean, unobstructed, and undamaged. Dust, moisture, or scratches on the sensor window can impair scanning performance.
- Manual touch-up option — Use the Remote Control feature in the app to guide the mower manually and trim any missed sections.
Environmental factors
- Mowing area size — If your lawn is large, consider increasing both the mowing duration and frequency per session to ensure full coverage.
- Obstacles in the mowing path — Remove unnecessary objects (e.g., toys, garden tools, low-hanging branches). Also inspect the uncut area closely—some small obstacles may not appear in the app map but still physically block the mower.
-
Grass height — Extremely tall grass may exceed the mower’s maximum cutting capacity. For guidance on acceptable grass height and performance with weeds or overgrown areas, see:
Question: How good is the mowing performance? Can it handle tall grass or weeds? - Grass density — Thick, dense, or fast-growing grass can overwhelm the mower’s cutting ability—especially when combined with height or moisture. Consider more frequent mowing to prevent buildup.
- Slopes and uneven terrain — Missed areas on inclines or bumpy ground may result from wheel slippage or reduced traction. Ensure your model supports the slope grade in your yard, and check that wheels and drive system are clean and functioning properly.
- RTK signal interference — Confirm the RTK antenna hasn’t been moved or obstructed during operation. Also note that heavy rain, fog, or strong electromagnetic interference can temporarily degrade RTK signal quality—leading to positioning errors and incomplete coverage.
