Finally brought my Bosch Indego out of the garage where it's been hibernating for winter and it's already doing a cracking job again, one of the best purchases I've made, and I've only got about 380sq/m of grass
Guess this arguement has taken a strange turn, people who are young enough to want a robot and have a lawn "big enough" to bother (I'd say any lawn is big enough, mowing the lawn is a complete waste of anybody's time in my opinion, way better to get a robot to do it and better for the lawn too.. ) is probably working long enough hours that they are "time poor" even if objectively not "struggling to make ends meet", or certainly have better things to do with their spare time (like arguing on the internet perhaps)
