The Whirlpool power nozzle I’m referring to might be older.
I’m thinking of the nozzle that Whirlpool paired with their household canisters in the early 60’s, only I played with it as attached to a commercial type canister with a cage on top to store the hose. I guess you could call it an L-shape nozzle. I remember seeing a pic of Tom G’s. It was black. Anyway, one of my Grandmother’s neighbors had one. They lived in one of those sprawling MCM ranch homes from the late 50’s full of wall to wall carpet, so I would imagine it saw a lot of use because of the longer hose.
