First observation: the robot is pretty impressive size level, I'm not expecting a package and as big vacuum cleaner. After this surprise, these dimensions are not at all bothersome in use everyday. The grip is very intuitive ("clean" button to start cleaning, "spot" button to rotate the robot around a specific area), so that I could start the first cycle of the robot without plunging me in the record (it was already busy unpacking!). I still have plenty of modes to explore in more detail, so some seem very useful (programming a cleaning day). I have not yet tested the block "virtual wall" provided, which I honestly have no utility. I found this vacuum bit noisy, and very effective cleaning level (including through a rotating brush that can collect dust along baseboards). With each use, it is automatically returned to its "dock" to recharge, so it is truly autonomous (I do not know if I was lucky, but I have never yet found blocked) . Its maintenance has proved rather easy (drain pan and brush can be easily removed). In short, while I was not actually do some of the utility and effectiveness of this type of premium device first, I was very pleasantly surprised!
