Some of these like the Garment air-bag, go back to the mid to late 1930's. What are posted here are the first patents. Keep in mind that after the attack on Pearl Harbor, all companies, not only Electrolux went into 'War production,' and this brought a halt to all vacuum cleaner designs. So, when Electrolux went back into production it was the refurbished model 30, and the above-mentioned tools were introduced. Adding to these were the vaporizer, and spray gun, both had been part of the line since the model XI (11) in 1927. To round out the new tools, Lofgren came up with the idea to add white bristles to the floor brush, thus turning it into a wall brush for things like wallpaper, and doing likewise with the dusting brush, thus adding two brushes to the line. As for the disposable bag, which would be called a 'wrapper,' it was already on the drawing board and would be introduced with the model LX.
All of these tools would carry over to the model LX in 1952. As for the power polisher, it would become the 'Turbo' tool in the 1950's. Gustav Lofgren also designed the combination tools used for the models E, and E automatic, and of course these became the standard still used today.
And in case you're wondering what was sold during the war? that was the model XX (20.) It was slated to replace the 30, but for some reason, the machine was scrapped. I have one and it was great. Incidentally, the logo on the early cans of wax, floor cleaner and so on, show the model XX.
