Ok, so I posed a question about converting my 825 to a bag type system. After an alternative was offered, and I did hours of research, I wondered why I would want to convert? I like not having to change bags all of the time. The answer is, I despise the slide on clip on the top of my hoover bag. It's damn near impossible for my arthritic hands to reinstall. Is there a better upper clamping system for a shakeout bag?
