In my case, my lawn isn't easily accessible and also not visible from the street (because the house and garage is between the street and the garden), and I trust my neighbors. So, I think (I hope) this isn't so much an issue for my case.

I think the eufy has also an optional GPS module just for this purpose, to better track it. I don't think this GPS module has any other purpose (e.g. it would not be used for navigation). But I didn't really checked the details on this.

I have seen this a few times for such robots, that you can buy an optional GPS module for tracking.
