There was an experience of using a robot of earlier versions (2-3 years ago), though another company. Mapping performance, suction power, flotation, obstacle detection have been greatly improved compared to earlier versions. In general, I recommend to buy, a great helper! Cleans an apartment of 3 rooms in 45 minutes on average. Got pros: Builds maps efficiently, keeps order well, kids are busy. Has cons: I could not find the cleaning settings so that in automatic mode I could clean part of the apartment with a sink, and part of the apartment only with a vacuum cleaner. It is necessary to remove the mop after cleaning, so as not to spoil the laminate (according to the instructions).
