Arrived super fast but unfortunately NOT an original replacement roller for the S3755 cylinder vacuum. The original roller is designed to help with suction, this roller is very basic and does not allow the vacuum to be 100% effective. Absorption has been greatly reduced. It doesn't fit perfectly either. Returned. I tried ordering a replacement reel directly from Hoover but no luck even then - they sent me that exact reel (but it broke and I had to pay outrageous shipping costs). I finally found an original design replacement roller in the Vac parts store. Funny since the Hoover rep said they are no longer made.
