I havent had this vac long but i like it a lot! Its a little heavy but it does an awesome job!!! Much better then my hoover windtunnel ever did. The controls were very stiff at first but are wearing in nicely and much easier to use now. the button for the roller control was the worst but getting a bit easier...it is a little bit of a pain where its placed on the machine and i tend to leave the roller going when i move to the bare floor. all in all im very happy with it so far!!!
