Thanks eurekaprince. That's a helpful tip. I'll see if there are dealers nearby that can help me out with this and I might shoot Sanitaire a call. Since this model has been discontinued for a while now, I'm a bit worried they might not have the most accurate information or any information about what shakeout bag would be compatible.
I didn't even know there were different types of Sanitaire shakeout bags. I had always assumed they were all the same. I also want to avoid going to a local dealer because I have a feeling they will try to upsell me things I don't need or not be interested in helping me unless I'm guaranteed to buy something from them.
I should be receiving the vacuum soon and I have 1-2 leftover shakeout bags that I use for other models. I'll find out once I get the vacuum if I can just swap the bags. I just wanted to make sure of things before I opened the box and took everything out, so I decided to ask here before doing that.
I'll leave an update once I get the vacuum in case others are interested in replacing the ST/F&G configuration with a shakeout bag with this model or similar Sanitaire models. I'm doubtful there are many out there looking to do that, but who knows.
