Perhaps I'm overly optimistic, but I think there is finally a robot lawn mower that looks decent enough for me to buy and try.
I have been waiting YEARS for a no-wire tracked mower with actual mulching blades (instead of the silly razor blades or string trimmer hunks of junk).
It certainly isn't cheap, but if it lasts for 3+ years and I don't have to mow for 3 hours each weekend, then it's a good buy.
