These seem to be Aerus manufactured machines built for another company, and would give us the convenience we want in an upright for occasional use between Guardian deep cleanings. While a Guardian upright would be the cat's meow, they aren't so common in the used marketplace, but new ProTeam 15- versions seem very available new. I think I know what I'm looking for Re: Guardian, and I think I've found an upright solution - the ProTeam "Aerus clone" commercial upright. Save for a bit of storage floobydust which I cleaned up it appears out of a time capsule. The "hunt" is on, and has already brought results - found an unused Electrolux floor shampooer for $50 (sans carpet brushes but with naplifters) at an estate sale locally. This has been a great help - as is this site. Post# 234433, Reply# 2 at 02:00 (3,247 days old) by electromatik (Taylorsville, North Carolina, U.S.A.) Other Lux experts might help you more with more specific time periods. The top of the line is the Guardian Platinum and is black and stainless steel. The current model is the Lux Guardian Ultra and it doesn't look like the older ones, it has the older body style with silver painted top and no "box" on top. They are still using the name "Lux" because that was the name of the first machines and this still appears on their machines today. I believe the Lux 9000 was a more recent model (perhaps 2009?). The ones with the oval Aerus name ONLY are mid-2000's after the transition period ended. The name changed, but it was still the same machine. Aerus-Electrolux branded machines with the clip-on "box" for the HEPA on top are usually early 2000's. I think Electrolux began adding the "box" on top for the HEPA later. So, basically speaking, if you see an Electrolux Guardian with no HEPA filter, it was one of the very early models prior to 2000. Electrolux AB allowed Aerus to continue using the Electrolux name for a period of several years. Electrolux USA chose Aerus as the new name.

In 2000 or so, Electrolux USA sold the name to Electrolux AB of Sweden but there was a transition period. They began production of the model called Guardian shortly after that, with the biggest change being the handle controls changing from electronic to slider switches. You are correct that the Renaissance was the first of the line. Post# 234431, Reply# 1 at 01:23 (3,247 days old) by electromatik (Taylorsville, North Carolina, U.S.A.) I'm also looking into a recent version upright, as well as possibly getting an Electrolux Shampooer to have all the bases covered - but particularly I am interested in the production "order" of these various Guardians, as well as any hidden features/benefits/drawbacks that may exist amongst them. So what I'm trying to do is figure out an "order of production" on these recent Guardian machines - which are earlier (closer to Renaissance age) vs.
#ELECTROLUX C104A SERIAL NUMBER#
Can these be "dated" by serial number in any way?

Within the Guardian line, however, I am having difficulty figuring out which ones are more recent: Some say "Electrolux" on the canister, some say "Guardian", some say "Lux 9000" - some have the ovalish "Aerus" logo atop the canister, some say "Lux Guardian", some say "75th Guardian" (assuming that one is a bit older?). the collar connection found on the step down models (which admittedly are probably still good machines). The Guardians seem to have the features I want - adjustable speed of suction on the handle as well as what appears to be the better of the two Aerus/Lux hose connections to the canister - the seemingly firmer "pin" connection vs.

I have figured out the "start" of that generation of machine - the Renaissance - but get a little confused trying to "date" the versions of similar looking Guardian machines. In particular, I have been scanning the more recent Aerus label canisters - the Guardians in particular, as they seem to have the feature set and top line performance. Having been an owner of Electrolux vacs (Super J and QVC version Ultralux upright) I am likely to stick to the Aerus/Lux brand, and looking to replace both, which have seen better days - I'll likely donate them to someone in the biz who can restore them or cannibalize them for another restoration. I also find that once a unit has been in the field we get to know it's faults and strong points better. I am the type to buy late model high end equipment, to save $$ and get the most mileage for the buck. It seems to be time to find some new cleaners, so I figured it best to ask the experts/enthusiasts for the lowdown on what's what in recent Electrolux (Aerus) machinery recently available :-)
