I have an old Dirt Devil vacuum and these bags are hard to find. Bagless vacuums are terrible. I only use bagged vacuums. My dirty devil is glued and patched in various ways, but I will not part with him. The best canister vacuum cleaner I've ever bought. So I always have to buy the right bags and they are perfect. It's hard to find anywhere else, and most vacuum stores have gone out of business, making these packages even harder to find.
