I spend more time trying to get this thing to work then it would take to cut the grass myself. I have it set to cut 1.2 acres. I have had it for about a month. It has yet to cut the whole yard. It sits in a shadow of a tree and says it stuck. Then I follow the directions on the app to clear the error code, but the code never clears. So then I have to carry it back to the charging station to restart it. It then drives back to the same spot and says it’s stuck again. I will probably attempt to return it this week. When it does get going it does a good job, until it gets stuck on nothing again…..
