Not really good for dog hair

And Dog hair was the reason for this choice! We have a medium collie/sheppard mix and he has lot's of hair and is always shedding. We chose this vacuum based on the lore of the Dyson. Well, it was a complete and utter failure. The bottom part is so narrow that the hair clogs within minutes. So, your vacuuming for 5 minutes and spending half an hour taking the whole bottom assembly apart to unclog the too small tube. Bottom line, not this item did not do what it was supposed to do.
