Would you like an App controlled mower or not? 

What is the Size of your garden?

If you don't understand the first question then just go with the second.

Buy a Stihl robotic mower don't mess about with anything else you would have to be an idiot not to, we haven't tested every other machine but we have tested quite a few and so far the Stihl is a mile ahead, so the machine you will see attached to this blog is a Stihl RMI 422 PC. Its App controlled and a breeze to setup it was working 2 hours after i received it and 20 minutes after that the lawn was cut OK so to be fair the lawn is tiny but the machine worked flawlessly the App password needs to be sent from your Stihl dealer to make this function work and I didn't have the access when i started the mower and i didn't need it. So when the App is setup i would expect much more date and run time control.
