Sanitaire Brand and Model History

[paul]

Paul,

This also makes me wonder if the current Sanitaire logo with the stylized "S" also first appeared that year?

I'd love to hear from somebody who remembers buying an S639, S644, S646 or S648 in '82!

Ben,

I was unable to locate any online Sanitaire trademark information regarding the stylized S.

I also searched all the models you listed and found only one newspaper ad for the 3684 compact canister and the S639 from 2002. So did Sanitaire routinely produce its models for twenty or so years, or was the S639 an anomaly?

While I found no digital newspaper ads for it, I did locate a couple 1960s references: a snippet view of a 1962 NAHHIC (National Association of House to House Installment Companies) trade show; the name being changed to DSA (Direct Selling Association) in 1969, and a 1965 trademark entry in the OFFICIAL GAZETTE OF THE UNITED STATES PATENT OFFICE.

It would seem that Sanitaires were sold door to door in the 1960s, which could be why there is so little print information about them.

Interestingly, the motor ratings are the average for the Eureka Super Roto-Matic 900 Series and even less than the Heavy-Duty model-type 948-A and the later standard model-type 980-A (see the attached abridged 900 Series table).
