After doing a lot of research about all kinds of robot vacuums, I ended up ordering the K11+ because it seemed like a perfect combo of having the same suction power and features as all of the other proper robot vacuums from other brands (many times with higher price points), and at the same time, small size so that it can actually get into places and clean them properly compared to any other robot vacuums in the market.
In the end, I was right. It cleans places really well without leaving almost anything behind while being surprisingly quiet even with the strong suction setting (Max setting can easily be heard from another room, but it doesn't really need to be used much, if at all). It actually goes between all the dining room chairs and other similar furniture, and makes sure every chair leg and its surroundings are cleaned, and it even fits under my office chair with the usual 5 point wheels to clean that area. The setup and the app are intuitive and easy to go through and use. The schedules, mapping and other settings are also reliable and easy to manage.
What this vacuum doesn't do, is that it doesn't see small obstacles like socks, or cables on the floor and use some AI tracking on a camera to neatly go around them like some of the higher end models since it doesn't even have a camera on it. But that is to be more than expected with this price (200€ on sale). My house is pretty clean from that kind of clutter, so I haven't had any problems with that, or the tracking in general, but it needs to be said, that it's not going to be perfect with the sensor setup that it has, but it sure does do a great and accurate job with what it has!
It also goes over pretty high bumps and steps too on the floor, and even cleans carpets nicely, which I was a bit sceptical of at first before letting it do its thing. It struggles a bit with the really thick ones when it comes to moving on them, or getting on top of them, but that it also common with many other robot vacuums, and it still does it and cleans them in the end. It also has the common thing, like many other robot vacuums, where it sometimes thinks that dark carpets are deep voids to some other universe, so sometimes it gets confused and doesn't want to clean that area, but there are ways to make it work normally, and it has only happened once with mine, and after that one time, it has cleaned that area normally.
Battery life has also been great, and charging doesn't take long either. Of course the size of the vacuum is smaller, so with big houses, it would need to do a charge in between the cleaning, if you want it to vacuum the whole place, and don't schedule certain rooms to be cleaned at different times of the day. But once again, it all just happens automatically and it will continue from where it left and finish the job after charging.
The docking and auto emptying works flawlessly on the dock too, and its really easy to place almost anywhere because of its size. The wood finish is also a nice touch when it comes to design. The design of the vacuum itself is also really nice, and every part that needs changing or maintenance in the future is easily removable and easy to clean when needed.
I'm trying to think of other negative points to mention, but at least for now, I haven't really found any others. It works really well, and cleans nicely even from places where most other robot vacuums can't because of its size. I love it, and will continue using it! Excellent product in my opinion, especially for the price.
