I have had this vacume for over 2 years and it works very well. I have had up to 3 dogs that shed at one time (now down to two) and it has worked so well on picking up their hair. I did not go with the purple Dyson at the time because I could not afford to spend the extra $100 for the extra attachments. I do not like how the trap is messy, I have to go out on my porch to empty it or I have a mess. Also it is heavy and you have to have muscles to use it on the stairs because the floor tools do not do as good a job either. I do like the manueverability that the ball gives it. I do not think I would recommend this to a friend
