My first Dyson Animal is an original more than 14 years old. I bought the Animal 3 to replace it after it finally started over heating. I would never buy any other brand vacuum. The Animal 3 has very powerful suction. Love this vacuum on hardwood floors and for pet hair. It doesn't blow the hair everywhere, but sucks it right to the vacuum. The pet attachment is great on the dog. Easy bin removal, and great for dusting the house. The adjustable settings are great for different flooring. The only reason a four star rating, it's hard to vacuum throw rugs even on the highest setting without the beaterbar rotating. Overall, I wouldn't hesitate to buy the same vacuum again! Thank you Dyson!!!
