I have all 3 of the bag options for my sanitaire. I like the top handle for the dirt-cup kit, big hook too hang cord, but the thin cloth bag on top was too dusty. I got a free shake out bag....it was new so I put the top handle of the old dirt cup kit and the shake out bag....lasted for a long time.......mega air flow. then got a free cloth bag with paper dirt bag....seems ok. found a donor vacuum in the trash. it was a old powrflite knock off of the sanitire, who ever ownded it before me put oem brush roll,fan and cloth bag and chord on it. funny knock off if you break the fan chamber you have too replace the whole housing....remove motor and everything...sanitaire it's a few screws.
