Hi, I've bought pure i9 2 months ago and I have to say it's an impressive and really efficient device. However after last sw upgrade to 36.13, it seems to me that robot navigation is different compared to previous sw. Sometimes it completly miss and not clean an area without any obstacles in the way, sometimes I found it cleaning areas already cleaned before and that's why it drain batteries sooner. Special case is thin carpet in living room. It does not have a problem to cimb over it and clean it, but cleaning is not consistent with pattern like on the hard floor, robot is just wandering on it and most of the time it not clean it completely. On the other side, carpet in another room which is thicker but also brighter is everytime cleaned without any problem.
I did several resets, but no improvement.
