What is 'vintage'?
The term 'vintage' would seem to be a little problematic, in that people may have different definitions of what that means. Going by the definition used on this forum, Any vacuum made before 2003 would qualify as 'vintage', which I question a somewhat, but whatever...
With the exception of a couple of Kirby Sentrias, Every vacuum I own would qualify as 'vintage', so that's all I use; that is, when I choose to vacuum, which is far less than I should. As much as I like vacuum cleaners and enjoy repairing and rejuvenating them, I'm not all that fond of housecleaning. I let it get ahead of me and then it becomes overwhelming. My machines of choice when I do vacuum are usually my Electrolux Genesis LXe, which is best for overall convenience or an Electrolux canister, such as my Diamond J or Diplomat LX, which are great in tight spaces. I love my Kirbys dearly, but they work best in open spaces, of which I have few, and the accessories are just too much of a pain to be truly useful.
