Frequently Asked Questions

How does this mower handle areas with weak GPS or RTK signals?
This product utilizes an enhanced vision navigation system powered by Visual SLAM technology. This allows the mower to navigate seamlessly through challenging environments, such as under tree canopies or near tall buildings, ensuring uninterrupted operation even when RTK signals are temporarily obstructed.
Can I manage multiple disconnected lawn areas with this mower?
Yes, the 'Drop & Run' feature allows you to create work zones anywhere without charging station limits. For disconnected areas, you can simply move the mower by hand to the new zone, and it is ready to start mowing instantly using its virtual boundary mapping.
What happens if it starts raining while the mower is operating?
The mower is equipped with an integrated rain sensor. When rainfall is detected, the unit will automatically pause its current task and return to the charging station. It will resume mowing once the weather clears and the sensors indicate it is safe to continue.
