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, level, and free of dents or damage.
- Upper body cover installation – Make sure the mower’s upper cover is fully and correctly installed. A misaligned or loose cover can interfere with the binocular camera’s obstacle detection, leading to reduced cutting performance.
Software factors
- Uncut area location – Check whether the missed area is near the edge of the mowing map. If so, confirm that Edge cutting mode is enabled in your app settings.
- Cutting height consistency – Avoid adjusting the cutting height mid-task. Inconsistent height settings can cause 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 orientation-related coverage gaps.
- RTK signal quality (RTK models only) – Ensure your mower has a strong, stable RTK signal. Weak or intermittent signals can reduce positioning accuracy and lead to missed areas.
- Lidar module condition (Lidar models only) – Clean the Lidar sensor window and verify it’s free of scratches, dirt, or moisture. A dirty or damaged sensor may impair navigation and mapping.
- Manual spot-cutting – Use the Remote Control feature in the app to guide the mower manually over uncut sections and complete the job.
Environmental factors
- Mowing area size – If the lawn is very large, consider increasing both mowing time per session and overall mowing frequency 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 on the map but still block the mower physically.
-
Grass height – Extremely tall grass may exceed the mower’s maximum cutting capacity. For guidance on recommended grass height and limitations, see:
Question: How good is the mowing performance? Can it handle tall grass or weeds? - Grass density – Thick, dense, or matted grass can overwhelm the mower’s cutting power. Consider pre-mowing very dense patches or adjusting frequency to prevent buildup.
- Slopes and uneven terrain – Missed areas on inclines or bumpy ground may result from wheel slippage or reduced traction. Check if slope limits apply to your model.
- RTK antenna placement and weather impact (RTK models only) – Confirm the RTK antenna hasn’t shifted during operation. Also note that heavy rain, fog, or strong electromagnetic interference can temporarily weaken RTK signal quality—leading to positioning errors and incomplete mowing.
