I prefer to use the dry mop, Belli, on hard floors that is. No trouble that one, but on carpet it's a different story..........I don't like the robot moving around when I am working.........too distracting. In a household environment it may be different, but those I know don't use it either. They still vacuum and the robot sits idle a lot of the time they saySo the vacuum cleaner, whether it works or not, still sucks. Fair enough.
