I have a Husqvarna 105 robot lawnmower. I have used it since 2018. I did not set it up, the installation of the perimeter wire and the programming of the mower were done by the supplier. The whole package cost me £1,100. I am well pleased with the robot, and it does a good job of cutting the grass. It will not cut right to the lawn edges, because of the perimeter wire, so I sometimes go round with an edge trimmer. The robot does not remove any grass clippings; they lay on the lawn and are absorbed into the ground. You can, of course, set it up yourself, but it takes some time and effort. The installer installed the perimeter wire with a machine. The robot has to be put indoors (garage, shed) in winter, to avoid frost damage to the battery, and the cutters should be changed at the start of every mowing season. The mower saves me a lot of time (I used to spend about 1.5 hours with a push mower), and a lot of effort.
