Plus: Normally never stuck. Smooth - takes care of most furniture. Compared to the competitors, it is good to get up on rugs and over thresholds. Affordable (when you could get it for 6500). After updating it navigates well.
Minus: Short battery life. Having trouble with some thick and uneven carpets, as it should really do quite easily. Unable to delimit the staging area via the app or other accessories.
Like many others, my copy had trouble finding it back to the charging station when the battery started to run out, which, in combination with the relatively short battery life, often made it home to a semi-detached home and a robot standing in the middle of the floor Battery.
But after an update last week (15/3), all of these problems have disappeared completely. Has not run it more than three times since then, but has always found it back to the charging station, first to load, and then when it's ready. So in each case 6 times out of 6, it has found back after the update.
Additionally, the update provided that the app now displays stub reports with a map showing where the robot has been, how long it has been on and the like.
Another improvement with the update is that it seems easier to get over thresholds and carpets that it had problems with before.
