I bought this a couple weeks ago. Decided it was worth it to me to buy a dealer only model for the extra warranty and local service.
It would have helped me in deciding on which robot to buy if I could have seen a timelapse video of a few different models to see how they work.... so in the event it might help someone else I made my own video.
I read (quickly) through the forum rules, and I think I'm allowed to post this link. If not, apologies in advance.
