I was tired of having to clean out my old vacuum every time I had to use it. I would have to take it out to the garage, take it apart, use the air compressor to blow the dog hair out of the hose, have to blow the filter clean, and anything else that was clogged, I had to do that 2-3 times while vacuuming with my other machine. I was in the market for a new vacuum, Hubby suggested us getting a Dyson, I was against it because of the price being so high, but he had a good argument, 'We can keep throwing money away on other vacuums every couple of years, or buy a Dyson.' I read reviews, and they were good. We now have a Dyson. I can tell you one thing, this vacuum really does suck! ( I mean that in the best way possible!) I love it! I love the way the handle extends out to where I can reach the cob webs in the corners with out having to stand on a stool and have someone hold the vacuum because of the short hose. So far, I am completely satisfied with my Dyson!
