Dogs: poor training and laziness. Take your dogs out and they won’t poop your lawn (and walking the dogs is good for the soul).

Robot mowers may deprive you of the pleasure but they are also very good for your lawn as the tiny bits cut are small enough to remain unseen yet re-fertilise your soil. Downside is they don’t give weeds a chance to blossom (or should that be bloom?) and therefore deprive pollinators from a food source.
