I'm sure the 63 was the first upright to use disposable bags, and maybe the 82 blue Constellation for the canister, but I'm no expert, just based on what I have here in my collection.
Go back further to about 1930 and the little known Hygeinisac (?) that fit in place of the cloth bag and could be emptied or thrown away when full.You will find them in every Hoover closet next to the Duster with attachments!
