I bought it as a help in a bachelor's life for cleaning my 56 square meters in a typical panel kopeck piece. Systematically and methodically bypasses every difficult corner and obstacle. Particularly pleasing is the ability to automatically increase power on the carpet and rug in the hallway. I put on automatic cleaning three times a week while I go to work. It copes with its task with a solid 8 out of 10. At the same time, I put 10k only for myself when I run with a handheld vacuum cleaner.
