Hi Lovelux:
The history of that model is very interesting. Basically, Electrolux wanted to do something spectacular after WWII, and they did! The model LX was 6 years in the development stage, and one of the first to intruduce the disposible bag. Please note I didn't say 'the first.' Actually that honor went to Air-Way in 1920. Then Hoover jumped on the band waggon with the Hygenisac (exact year I don't recall.) But Electrolux perfected the 'full bag' alert system. What Electrolux wanted was a self-sealing bag, and created the 'wrapper,' meaning that the dirt was wrapped like a package. They used to advertize that it could be tossed onto a white table cloth and there would be no dirt. The slogon was 'see no dirt, touch no dirt, breathe no dirt!'
If you read the thread I spoke of there are members who address the issue of the rear filter, and I'm sure there are members here who have them.
I've already addressed how I got interested in the model LX, but like you, I was a child when I saw it eject, and it created an obsession with the vacuum cleaner.
And yes, I use my model LX as my daily driver.
Alex.
