It's a fair question to ask how much that extra money buys you. That Electrolux is of comparable vintage to the Kenmore Whispertone I just cleaned up tonight (see "My new Hoover" in the vintage section). Someone offered a really clean Kenmore Whispertone vacuum with Powermate, hose and Pet Powermate in the Hoover section of eBay. I guess if you squint real hard or drink enough it might be mistaken for a Hoover Spirit. I swooped and got the whole ensemble for $41. When those vacs were made there was a good $700 separating them from an Electrolux price wise. Go ahead and look at the images of my tear down of that Whispertone and you tell me if the extra money that Electolux charged was worth it. I don't see it.
Both have some flaws compared to modern vacs, the Whimpertone has no exhaust filtration at all and I don't have a work around for this either. I enhance the Kenmore foam secondary filter with Electrolux bulk filter material like I do with all my Kenmores (does that make them Electromores? Or maybe a Kenlux? 
), but I had to use a Kenmore secondary filter to protect the motor intake of the Electrolux "shop vac" cuz there's nuthin' between the bag and the fan on that beast, not even a cheap piece of foam to catch the bigger chunks.
Motor wise, are you going to tell me that non rebuildable Electrolux motor that has no provision for even replacing brushes is superior to the big two stage Lamb in that Whispertone? Both vacs have outstanding motors, but the Lamb motor can be rebuilt a couple of times in it's life and you can see from my images that the original brushes are barely worn. This thing is at least 15 years old but it has most of it's life left in it still.
So is that Electrolux really worth the more than double the original sales price of that Kenmore? That's not hostility, it's a legitimate question. You can look at my images of the tear downs of both vacs, and some earlier Kenmores of mine and be your own judge regarding their relative quality.
