Just showing that the Hoover filled up the bag in less then 24 hours. I had a Hoover V2 bagless and its broken, so a got a Dirt Devil bagless vacuum. It was cleaning good but, I found a great deal on a Sanitaire vacuum and bought it. It picked up a bags worth of crap in my house. I ordered a Hoover Windtunnel to replace the V2. I was sure that the Hoover would be better then the V2. I got this hoover last night and within 24 hours I filled the bag up on it. I did not do anything else then just vacuum the floors and 2 dog beds. I am not saying that the hoover is better than the Sanitaire. I believe that Sanitaire is a better vacuum.
