Dyson gets shit on a lot, but I’ve had a ton of luck with a Dyson V6 cordless stick vacuum. I bought it used about 7 year also and it’s still going strong. The main issue is that eventually the battery wears out and you have to replace it. It’s only 2 screws to remove it though.
Also. if you aren’t willing to service them, they might “die” within a year or two, but with a little bit of elbow grease they can last a long time. The good news is that because they are the name brand, there are a bunch of videos on YouTube with ways to service them, and replacement parts are plentiful.
