Interesting product I wish this had been around many decades years ago when I was sent out to mow my family's yards with a push mower! What about the lawn clippings? Unless this thing grinds up the cuttings to a fine dust, the first strong winds will deposit cut grass everywhere. Also thinking back on that time, I would encounter obstacles such as dog poop, dead birds, tree branches, etc. Maybe dog exhaust is no longer much of a problem now with most dog owners responsibly bagging it but for the rest it seems you still need to do a 'walk-through' of the property before unleashing it. I'm glad the reviewer pointed out the cloud vs local network issue; internet connectivity seems to be assumed on many new products. If it can do 98% of the job, that's still a great timesaver.?
