I have been using sharks for the past 10 - 12 yrs now. I still have my original one I bought which was the shark rotator with the caddy turning it from upright to canister. We have always had 4-5 big dogs and a Himalayan cat. All long haired dogs from golden retrievers to Berne's mountain dogs and had a dycon that didn’t even pick all that hair up. That is what led me to try the shark and I was sold every since. Then I got the stick for when I’m in a hurry and want a quick vacuuming and decided to really invest and I love my canisters. I have both hard wood floors and carpet so need it to do both very very well. This is my 3rd and I absolutely love it. Worth every penny. It has suction like no other, the cup holds a lot of hair and dirt, I can do the stairs which has carpet on them, the hose is plenty long enough and the canister doesn’t flip over and cleans up easily. I’ll never get another kind of vacuum again.
