I'll say a vacuum.
When I was a college kid in an apartment I bought the bottom-shelf, bagged Dirt Devil vacuums and dealt with it. All the clogging, hair in the brush, cheap quality/you get what you pay for, etc. Then I moved into a house I got a mid-range Bissell to help deal with all the pet hair. The thing was questionably designed, still got a bunch of the hair in the roll, and needed regular upkeep to make sure it functioned properly. When that one went out I wasn't going to pickup the same thing even though it technically lasted for years.
I recently picked up a Shark Rotator and it sucks in the best way possible. Was it expensive? Yes. Was it worth it? Absolutely. I can vacuum my whole house knowing I'm getting as much dirt, dust, hair off the floor as possible. And I'm not going to have to deal with even half the problems the low-end vacuums have. It pivots and gets right up against walls. There is a clear window to see the brush roll from the top. It also uses fins that just don't collect hair anyway. The whole canister comes off in one easy motion and I can dump it without spilling all over the now clean floor. There are two roll speeds for hard floors and carpet. The brush roll doesn't spin when it's locked upright so it's not flinging stuff around or grinding into the carpet while I try to clean corners or the couch. And even though it's one of their "heavier" models it's still lighter than the Bissell I lugged around for years.
This is a case that better design and features comes with a price. And those design choices can directly make your life easier. So if you can afford it, go for it.
Remember when we had a whole impeachment hearing against Trump for withholding aid to Ukraine so he could get a political hit piece on Biden? I'm wondering how long it will take before a quid pro quo scenario pops up again. Either in Ukraine or elsewhere. So ya, we're all feeling for Zelensky in the next few years.
