AIRBELT E3 Premium
Ultra-durable, 10-year warranty, but expensive with short cord.

I currently have a Miele L1 Guard Dog & Cat, and love it! Great suction, and the length of the cord means I can go everywhere in my house without issue. I do have to clean the brush head once in a while of wrapped up fur, but it's miles ahead of when I had a Roomba.
I got mine through Costco and only the L1 was available, but so far, it's been great. There's no big bells and whistles like the C3 (doesn't have the adjustable brush head) but I have been using is daily to twice a day for several months and zero issues. Just have to go in once in a while to clear the brushes of dog fur.
Just got the Miele Guard L1 Cat & Dog (successor of the C product Line) and it's by far the best vacuum I've ever used. I have 3 pomeranians and a lot of carpet but the vacuum works wonders. (I have not tried the Others on the list)
I also have this one and it works great!
I just bought the Miele L1 cat and dog. Winter is ending her and we have cat hair all through the carpet and rugs and it coped fine getting all that off with ease.
The Miele in Canada have 5 year warranty, the best of all cordless, so I certainly recommend looking at them. The battery is 2 years warranty it can be replaced . No matter what you will have to do maintenance, cleaning filters , emptying it out There are some duoflex in Costco for $449 I suggest that if price is a concern the battery is not a cartridge but can be replaced still Also note that length of warranty mean more than replacing the battery, if the machine fails after a year (which is most cordless warranty) then who cares about the battery as you have a useless machine now Lastly as others have pointed out if you want maintenance free a bagged vacuum that’s plug in will last you longer and be easier to deal with Again Costco has the Miele guard l1 cat and dog an although it’s an air turbo brush it’s a great machine for the price and still has a 5 year warranty and 7 years on the motor
I suggest the Costco guard l1 cat and dog plus , it’s $499 though but comes with both a good hard floor tool and a turbo brushed Depending on how much area rug you have you and how thick the pile is the c3 limited edition at $449 right now is also a great deal In Canada they all come with 5 year warranty parts and labour
Definitely seek out and visit a Sebo/Miele dealer so they can demo all your options. You will likely get a discount and/or additional goodies thrown in (bags, filters, attachments). Whether it's Sebo or Miele, the lower cost units are suction only and won't clean your bedroom carpets effectively. Make sure your choice has a power nozzle (Sebo E3, K3, D4 or Miele C3 cat and dog). Miele just rolled out their replacement for the C3, called the Guard series. Unfortunately, there are only 2 models with the power nozzle, so if you are offered the newest model make sure it isn't suction only. Oddly, the new Miele Guard Cat and Dog does not include a power nozzle option! There are clearance deals on the previous generation Miele's, I'd go that way over the new/full markup models as these machines are excellent (Marin and the white Cat and Dog C3s are my favorites).
I have Sebo and Miele vacuums and use them to manage two active corgis and their various messes. Both brands are excellent choices, but I tend to lean more towards Sebo for the better warranty, washable brush roll and cheaper cost of bags and filters. Pick a model with a power/electro nozzle for your capets. Both brands have chevron-designed brush rolls and with high suction are effective at resisting hair clogging. I also recommend a canister, if that is not ideal for you then the Sebo Felix is the best upright option because the floorhead can be switched over for bare floors. Recommendations are; Sebo K3, E3 and D4 (listed cheapest to most expensive), Miele C1 Cat & Dog, C3 Kona, or Guard L1 (light blue body).
The first things you'll notice about a modern vacuum is how quiet and compact they are compared to your Silver King. The Sebo D4 Onyx (or any Onyx version) opens the door to dealer-only extended warranty, pricing and accessory packages; 10 years motor/casing, parts and 7 year labor. Now that Miele rolled out their Guard series of vacuums, remaining stock of C3s are discounted. Standard warranty on a C3 is three years, but if there is a HomeCare edition (Red color), they are the Meile dealer-only line and warranted to 5 years. Only the entry level Miele's are Chinese, the majority are manufactured in Germany/Europe. The Guard Titanium is the current, dealer-only model from Miele. Both brands are BIFL, and the canisters are the GOAT for whole house cleaning (dusting, furniture, stairs, etc.). The D4 is designed for larger homes (40' cord, 1.5g bag). The Sebo E3 and Miele C3/Guard series are in the sweet spot for the average size home with a mix of bare floors and carpet. Models with a power nozzle will provide the most versatility to grow with your needs as you move from rentals to your final home. Get both brands and various models in your hands and test drive them in store. Black Friday is coming and these are always discounted this time of year.
Congratulations and look forward to your follow up review after a whole house cleaning. Miele did a poor job assessing the US market for the Guard series. We get the same handle and hose as the previous models; not the new handle with controls released in Europe. They discontinued the SEB 236 power nozzle (LED light, lower profile), and only two models with a power nozzle. None of the Cat and Dog models have a power nozzle! The new Fiber TeQ All Floor attachment looks promising though and will probably be added to my C3's arsenal of tools.
Miele rolled out their new Guard series canister vacs and all of the existing C3s are on clearance now. Find your local dealer and go visit the store. You need a powered model (entry level units are cheaper because they don't have the powerhead or electrical hose). Also look at the Sebo Felix. Awesome upright machine that handles carpet and hardwood floors, with excellent filtration.
