Well I dropped the swamp and broke it. My vacuum cleaner is 4 years old and still working so I was very happy to find this replacement part. While at it, I also bought a Hoover Linx Platinum Stick Vacuum BH50010, a Cyclonic Stick Vacuum SH20030 Roller Brush, and a belt set. Part numbers 302726001 and 001942002. I am very proud of myself for not being mechanical by nature. But replacing everything turned out to be very easy. Now I have a new vacuum cleaner!
