I have owned a Shark before but were ready for a new one. I have boys and a large, furry dog. There is so much satisfaction (and disgust) in seeing the canister full every single time. We had it shipped to our bakehouse that hasn't had a "real" cleaning in years and I was blown away. Only issues I have with this machine is that it doesn't have a place to store the brush roller attachment without removing another extra piece. Other than that I am happy!
