I am NOT a vacuum cleaner collector. Honestly. I've been vacuuming my whole life (soon to be 60 years), and I never worked with Kirby, until recently.
Three weeks ago vintage Omega was given to me, and I was blown away/sucked in! Then I tracked down 515, and yesterday I put "WANTED" add on Craigs, despite my wife's horror. I am NOT interested in any other brands/makes! None.
There is something in these machines that transcends decades and human lives. I am interested in adding only two more to the family, Dual Sanitronic 80 (1967) in avocado green, and something else (haven't decided yet about the last one). They will all be restored to new condition (by me, NOT by the factory), and they will work daily. They'll have their bags emptied every day, wiped down, and put on "display" again.
Since the 60s, I must've used just about every vacuum cleaner available (except Kirby). There are machines out there that clean as good (or better) than Kirby. There are machines that are more "user friendly". But what I get from vintage Kirbys is a combination of performance, durability, sound, and artful design. No other machine has all that in my eyes. When you see one of these 500 series machines, all dolled up, in action, you bow down to the inventor/designer, that created something timeless like that.
And that's it. I'm hooked on Kirby.
Merry Christmas to all of you.
