I would recommend the YUKA Mini 1000 for your lawn. Unlike many other models, it features LiDAR guidance, which allows it to navigate much more effectively under trees and in built-up areas where GPS signals can be weak.

You can see this mower in action and get more details in my review here: https://easylawnmowing.co.uk/mammotion-yuka-mini-2-review/
