If you think about it, Whirlpool was private labeling a lot at that time. Kenmore certainly. But they also took the power nozzle they were making for Sears in the mid 1960's, added a fan to the neck, and added a red bag to the handle, calling it an Advance. They added a hard bag compartment and called it a Kenmore. They added a wand and called it a power nozzle. Before the Oreck was an "Oreck" it was a black Whirlpool. Oreck sold it as a Whirlpool, then changed to McDonald Electric when Whirlpool discontinued making any other vacuum than for Sears.
