Compared to the neato D8 I once had, a huge improvement. I can’t compare it with similar modern robots, but I certainly don’t regret spending money on this one. Got pros: I have been using it for six months - the flight is normal. Apartment 85m2, 2 longhair cats. Never sucked something right, everything goes around. It rarely gets stuck (and in these places no robot passed). Got lost once in a while. Batteries are more than enough. Drop dead application, you can edit the rooms that the robot copied, assign them different cleaning modes (such as do not wet the floor where carpets or parquet, etc.). Full control up to control the movement from your phone. If you put the application on two devices, maps and settings are synchronized Cons below: 1 The container is too small for us - it is filled with cat hair in one cleaning. Ideally, I would like to clean it when emptying the tank, every 3 cleanings. I saw reviews that garbage is badly shaken out of the container - I think this happens if you do not clean it on time when the container is full. 2 Often complains (once) after cleaning that the sensors are dirty. Wiping doesn't help. It doesn't interfere much 3 Glitches because of the mirrors on the floor. In our case, this leads to the fact that the robot circles along the mirror for a couple of minutes until it realizes that it cannot be passed there. You can draw a "forbidden zone" near the mirror on the map, this will fix the problem.
