Cleans well on a solid 4+. Washes the floors for 3, but one robot vacuum cleaner does not wash them and do not believe those who say that it cleans them directly. Average cleaning time for an apartment of 65 sq. 35 minutes. Bugs, blunts, errors in the work are not observed. A huge number of settings in the application (spend about an hour setting it up). You can customize whatever you want. The robot from the application is controlled perfectly, at least use it as a radio-controlled car. Voice commands are recognized normally. It is possible to set up scheduled cleanings. There is a history of cleaning (with indicators and route). It is possible to specify which area to clean for which, how to clean, etc. Worth your money.
