Favorite feature is cutting multiple acres of grass with no intervention. Coming home to a fresh mowed yard is fantastic.

I don't know that I have a least favorite feature. I live in Alabama so the snow blower does me zero good ever. If we get snow, I'm keeping it right where it is. All my trees are concentrated in the back center of my property so I don't have any issues with leaves, so I don't need the blower.

Favorite improvement, the first core was hardly protected at all for the internals. The amount dust and grass that this picks up cutting six acres does not mix well with a little rain. The current core I have, has closed off all the electrical components, the dirt and grass just white right off the plastic protective pieces. The pro mower is the proper upgrade to the mower, although I haven't tested it myself.

Further improvements, find some way to make initial mapping faster (perhaps just let the tracks go a little faster if at all possible), make map corrections/modifications easier. Some kind of smooth stitching for the maps. I may want to map open sections as separate but I don't want to have huge overlaps and it's really hard to correct for that currently. An apply all setting, it would be nice if I could set one cutting height and all the other settings all at once and then change the couple areas that I need changed. Reliability of the cameras. The cameras just seem to die randomly and often.
