I'm just a very satisfied Robomower user. I picked up my Robomower during one of Woot's sales. For $185 shipped to my door, it was one of the best purchases I have ever made. It's hard to find a decent push mower for that price! I usually get pretty bad allergies during the summer, but ever since employing this robot to cut the majority of my yard, I haven't really had any allergy problems!
