we have have this vacuum for about 3 week now and be happy with it so far . it replace a 6 year old Panasonic which go south . it be noticeably heavier than we older vacuum , but I tend to use it more than my wife , so it be not a big deal for I . I may have to carry it up the stair for she though . assembly be limited and easy , and it have good suction . no regret , would buy again .
