Singer, or e.r. Ryobi made that...
That was a popular machine thru Sears, that "Twin-Fan" Commercial. It was nothing more than a standard twinfan machine, with two speeds, a grounded powercord, and a larger cloth bag w/ paperbag insert, rather than vinyl. This machine was made probably until 1992-93 or so And my 1977 Spring and Summer Catalog featured it, so it was in production for a VERY long time..
Again, it was the same as the other twin fan household units. This would have had the double brush, double beater bar agitator, and an 8 position height adjustment. My grandmother bought a new on in 1988, and she still has it and uses it as her basement vacuum. Someday, when I can ever convince her, it will be mine...LOL
