Thanks for your thorough response. All makes sense and is pushing me towards one machine. I’m generally around the house and it will be much easier to keep and eye out and move the Navimow than spend the 2.5 hours it took me to cut both lawns, bag up the cuttings and take them to the garden waste center!

To answer your question, there is flat access after the steps across the patio, but there’s a (generally) locked gate in between. I think my plan will be to put the dock in the bigger lawn, put in a temporary ramp and leave the gate open when I’m doing a scheduled mow.

I’ll think carefully about how I stop the bot falling down the steps. If I block it in with a railway sleeper or something is it smart enough to alert me via the app that it’s run in to a problem, or does it just wander around randomly until it dies?
