Function of the moderator only. When sufficient interest exists. You now have a thread. I have noticed more discussion of mowers at the German Roboter-Forum. (Maybe in the U.S. lawn tractors are more of interest -- more land.)
 Descriptions of several mowers at http://www.robotlawnmowers.org/
Many sold on Amazon
with reviews there.
 The Robomow U.S. website does not have a forum for user discussion as major computer makers have in connection with support, e.g. Lenovo. Of course, those general purpose products are much more complicated and present innumerable support issues for compatibility with many other things and constantly changing software. Samsung puts customer reviews on its website, as do some appliance retailers.
Lots of youtube videos are used by Dyson for promotion, understandably today.
This website here is particularly devoted to engineering and internals of these devices, repairs etc., even reverse engineering when needed.
