Eureka canisters
Eureka made some awesome canister machines during the 1950's, the Eureka 900 series is awesome, and the canned ham is also a great machine. They were late to the game with their power nozzle canisters but once they came out they were excellent, at least for a while. Unfortunately those days are long gone. Their express power nozzle is decent, although I'm not sure if that's even made anymore. It was sold as the Eureka Express and as the Beam Rug Master, since a different company now owns Eureka and Electrolux still owns Beam, I'm not sure how that nozzle will be labeled if it's still even made.
