I can tell you one thing , it certainly do suck ! Ours last no longer than 6 month before we give up on it and throw it out . only a week or so after purchase this vacuum , it start make a awful buzz sound that would not go away regardless of how many time you clean it or remove debris from the head . most of the time it seem like it be just blow dirt around rather than suck it up . the front of the vacuum be constantly cover in dust and vacuum cleaner powder .
