My so and I got a robotic mower as it was a better alternative to mowing strife. It works quite well (excepting the ac/dc power converter which inexplicitly failed after 1 year, but it was outside).
It did involve running (staking) a wire around the perimeter of the yard, as a boundary. There are a couple of tricky bits where it very occasionally gets stuck, but overall very happy with it.
The landroid cutters are strange, (think 2 inch long razor blades) and I was skeptical that it would do the whole yard. But it does. Its very slow moving, but like many robots incredibly persistent. It follows the border wire back to the charging station.
