Just my two cents here
I own a Prolux, I got mine last year for around $7. The condition was probably worse than the one you posted on here. I didn't had the time to clean it myself so I took it to a professional and had it serviced for $60 which wasn't too bad if you ask me. Honestly though, I like the vacuum but I don't love it. I was really disappointed that it doesn't have the suction or airflow as well as my Diplomat mainly because the motor is smaller, and the nozzle doesn't have the pressure to hit the carpets as well as my Diplomat. What I really like about the Prolux is that the cord is very long, the belt usually lasts, it's a simple vacuum, and they are durable. However what I don't like is the bags are actually small, there's a reason why they come in big packages because they need to be changed quite often, and if you do get bags avoid the blue Aerus ones because those are terrible. The filtration I would say is pathetic, these don't have a pre or post filter, you could get a pre and post filter for it but they need to be replaced because they cannot be washed so that's another thing to add while buying bags. There's no height adjustment on it. And there's no hose or attachments to store on-board the vacuum, that may not be a problem to you but I never liked doing that myself personally. So that's my thoughts about the Prolux. I'm actually putting mine up for sale because I no longer have interest for it. I'm still going to collect some other Lux uprights that I really want to get but this one just isn't my favorite.
Overall if you really want the Prolux, go ahead and get it. Electrolux isn't usually cheap to get so that's a good deal Goodwill is offering. Just hope the parts that it would need wouldn't be expensive to fix. If you honestly don't care about it and if you don't get approval for this, that's totally fine. I'm sure there are others out there that would want that more than you and it could eventually go to a new home. Also, there are still other vacuums out there that will clean circles around the ProLux, including the newer Lux uprights and the clones like the Perfect DM101 for example. Adin, I hate to say this but I disagree with you because there are some bagless vacuums that I have seen and used (Especially the department store ones) that the ProLux cannot out clean.
