I recently purchased this vacuum to replace my Dyson that I purchased after friends telling me how much they loved theirs. That was a huge and expensive mistake! When I vacuum with my new Bissell Pet Hair Eraser, I don't have to worry about following behind my Roomba to pick up the clumps of hair it pulls out of the carpet, even after vacuuming like I did with my Dyson. This machine picks up almost all of the cat and dog hair that's on my carpet, and it gets most of it on the first pass. I have 9 cats and 3 dogs, so you can imagine how much hair gets picked up on a daily basis. The Pet Hair Eraser really does cut down on the amount of vacuuming I have to do every day.
