This is a reasonably priced robot vacuum cleaner that, despite its affordability, does a fantastic job of cleaning. It is impossible for him to have missed any part of the room while vacuuming because he does a thorough job and does not allow any dirt to pass through the machine. He will drive everywhere and clean everywhere. I appreciate that it has a fairly large garbage container, which means that the trash does not have to be removed frequently and the dirt can be disposed of frequently because everything is crammed in there firmly and the volume is typically sufficient for a number of different cleanings. There are two turbo brushes located on the underside, and when they spin, they are effective in picking up debris from the floor. In addition to that, the maker is an American firm; after all, Chinese companies are inferior and cannot be relied upon as much.
