Amazon price: $150.00
I own this vacuum and it works great. Easily picks up the mess of hair from my Labrador Retriever. My only regret is that I didn't wait to purchase it until now at half the price I paid! If you are looking for a reasonable alternative to a Dyson than IMO this is a great substitute. Amazon rating of 3 stars. I have not experienced any of the problems/symptoms that the reviewers listed there. I only have positive things to say about this vacuum!
