Not the quietest vacuum I've ever owned but so are it's ability to pick up and contain not just my cat's hair but the strands of my own long hair that fall to the ground has been exactly what I was looking for.  No hair trapped in the main roller, and the bin does a great job spooling it all together so it empties out of the bin really nicely - I haven't had to reach in to pull out clumps of hair stuck in the bin at all!  I do recommend this vacuum for homes with both pets and long haired humans.
