Oxygen+ EL6988E

Get a used Electrolux Oxygen for about $100 which performs almost as well as a $1000+ Sebo E3 and is quieter.

Not at all. I have a 21-year-old Electrolux Oxygen that's light and nimble has a great powerhead for my area rugs a long hose and handle so it's great for crevices stairs has all the tools you need and it came with a motorized upholstery head as well that's also excellent for car cleaning. It's HEPA filtration and takes as Clinic bags so there's like no dust in the house when it's in use. I looked at buying a new one because of prong on the motorized rug cleaning head was broken while my cleaning woman was using it or trying to remove it I don't know how exactly. I found a replacement for it on eBay because it's no longer in production and vacuums with similar qualities are very expensive and this one has been pretty much trouble free except for a modest cost for hose replacement several years back. I keep the filters on the bags changed regularly it's been low maintenance lightweight very maneuverable a pleasure to use

Electrolux never again... their oval system is CRAP.

My Electrolux canister has a non-powered rug attachment with no brush and it works great on the washable rug.

In some ways, not much would change! Avoid bagless (filter queen, messy to empty), cheaper models would have more reliability problems though vacuums were simpler and easier to repair then. Good quality canister vacuum such as an Electrolux if you have a mix of hard floors and rugs. Electrolux also had better than average filtration for the time and was a bit more compact and easier to pull around than many competitors. Compact/tristar similarly a good option. If you had mostly carpet or prefered to sweep hard floors, a quality upright such as a hoover convertible would be hard to beat. Back when consumer reports was truly excellent (they're hit and miss now), Electrolux usually earned the top rank for canisters and hoover at the top for uprights.

I would really recommend an old Kenmore.  It’s a canister vacuum, you can still buy them new.  However, they show up at goodwill for like 20 bucks.  Replace the bag and filters, clean the roller and you have a really solid machine.  All the attachments are inside the body and it can be stored in a closet or under a bed.  Plus if something happens to it you don’t have to feel bad because it wasn’t super expensive.  Also a Electrolux canister is a great option too.  I will also say a Kirby, but they do take up more space and the hose situation is kinda bizarre.  They are like $1,000 new, but you can get them at the thrift store for like $50 bucks.  Also change the bag and belt on that if you get it.  They are built like a tank so you don’t really need to worry about it getting a little abuse. If you really want something new I think this would work for your situation: https://www.homedepot.com/p/KENMORE-200-Series-Bagged-Canister-Vacuum-Cleaner-BC4002/308593772?MERCH=REC-_-pipsem-_-308593689-_-1-_-n/a-_-n/a-_-n/a-_-n/a-_-n/a Once you get a house/ apartment you can look into a Kirby/Miele/Electrolux.  Just order it on line. Dorms can be a lot on appliances.

I use my old Electrolux or Compact/TriStar (both are canisters & use bags) bcuz I can get under furniture easily & no mess dirt disposal (bag contains the dirt). Also both have a mini power nozzle (Electrolux Sidekick & Wessel Werk HEB160) for vacing upholstery, stairs & 🚗 interiors
