Anyone have experience with the robotic lawn mowers?

I have a navimow h series, it was the only affordable no boundary wire option at the time. Since then the market has exploded with options. The navimow does the job, but the newer ones are better. Look around.

I have about .4 of an acre worth of grass, everything can be cut every two days, but I have it in three zones so everything gets cut every 3 days. I edge before it annoys the old guy across the street in the front, I hit the back yard up until the yard starts sloping towards the water like once a month. I let the bank grow up, it is full of native wildflowers and edibles and the previously mentioned on here pennywort that this board hates, and depending on what is there I could go a couple months or a couple weeks between cleaning it up.
