I had some reservations about him since I thought that he would struggle to deal with things like cat hair, carpet, and fine dust. Before I used the robot for the first time, I "ripped out" the flat with a regular Bosch vacuum cleaner and then started the robot to rustle around. Because of this, he removed a significant amount of dust from the carpet and the crevices, and as a direct result, I began to respect him right away. Now that I run it once a week, you can walk around barefoot on the floor and carpets without worrying about becoming sick. I just got a large vacuum cleaner out of storage for the purpose of repairs; otherwise, I don't even bother touching it when I clean normally. I decided to purchase some additional filters because the filter that was provided cannot be cleaned, and it appears to quickly become clogged with a lot of fine dust. Alternated once every three months.
