I give this system a solid 4 out of 5 stars. Pros: No more pet hair tangles. I'm not having to unjam the main brush daily due to pet hair being caught in the rollers. No fighting with clean/dirty water with the Refill & drainage System! The AI does extra on dirty places identifed.
cons: This system seems to have taken a step backwards on the AI auto detect system. With its ability to lift itself up a some it now trys to do weird stuff. I have some desks with extended horitzontial legs. The robot loves to high center itself on it. I had to setup no go zones so I don't have to save the it daily. My previous version would just bump and move on. This one oohh no it goes I can get over it, and quickly hi-centers itself and screams for help. It also does this with my office chair too, it loves to get stuck instead of just Identifying a chair like the previous version and just avoiding it.. Its AI needs some love.
If the lighting is poor or extra shadowed it will run over dog accidents and smear it around. While the previous version would do this sometimes. This one has a higher frequency of doing it. I'm guessing its cause the AI thinks its extra dirty and/or its an obstical it can get over and then smushes the mess. Again the AI needs some love.
I would recommend this to a friend!
