Landscaping nearing completion, grass seed going down asap. Going to need a mower or do I need a 'Robomower'?   Very rough guess maybe 1000sqm of lawn, with 800sqm of front lawn and various bits (all connected) of it. All fairly smooth and level but a few bits and bobs sticking out here and there (e.g. trees, sewage treatment plant stacks, patios, etc)   Anyone got experience of a robo-mower?
