It has been a decent amount of work preparing the yard for the robot mower. Not so much the installation of the perimeter wire, but removing garden beds we no longer wanted and some other alterations so that I would not have to change the perimeter wire once installed. And the perimeter wire has needed several adjustments as some parts were too tight and others too far from the edge. BUT the results are fantastic. I get a great amount of satisfaction watching the mower through the window as it works every day. It not only saves me from having to mow the lawn, but it keeps it at a perfect length instead of alternating between too long and too short.
