it does vacuum, that’s why i rated two stars
when it comes to intelligence, it doesn’t shine. 
it’s marketed as a perfect vacuum for pet owners because it doesn’t try to vacum pet’s tail. that’s true. what it also doesn’t vacuum is all the fur that my cats leave behind after having their little fights. i was hoping i could teach it to clean up the cat fur while avoiding the toys but it’s impossible. i can only change object detection from small to medium or big.
the learning option is quite limited: only certain obstacles are detected and i can send a photo for learning. the piles of cat fur are never an option.

it’s also quite tall and doesn’t vacuum under the shelves where it has 1cm+ available space above
