Out of curiosity, does your autonomous mower behave as idiotically has a autonomous vacuum like a Roomba? For a vacuum, that's okay, but for something on my lawn, I'd hate to see what the patterns in the grass would look like.
I clearly have no experience with one of these things, and just taking the worst of one and (most probably) improperly applying it to something else.
It's not the weight of the mower that makes the patterns. it's the direction of the suction, the direction of the rotation and cut. Sure, the wheels can leave a depression, but it's the cut that is important.
