I have the Hoover Windtunnel Max vacuum cleaner and these belts fit. Buy them in advance, because my vacuum cleaner picked up a blanket and I pulled it out when the vacuum cleaner was still on. You are supposed to turn off the vacuum cleaner, then pull out the blanket. Well, that was one of the first times I vacuumed with my Hoover and it ruined the belt, and I needed a replacement right there on the spot. I had one, because I went and bought this 2-pack along with my Hoover. A good practice.
