Instant pot/air fryer combo - I like that I can make one-pot meals in it as I really don't like cooking, and anything I make in there cooks fast. Pasta, rice, meats, there's so many recipes.
Bissell Green Machine - it can wash furniture/carpet. Great for spills, if you have pets. Wash the upholstery in your vehicle. Small and compact. I use it a lot.
Large Honeywell air purifier - my husband smokes a fair amount of pot. I really don't enjoy my space smelling like it all the time. This thing sucks up the smoke and I don't have to deal with it. I buy the replacement air filters on Amazon.
Steam Deck - I love this thing. I love gaming but I'm tired of sitting at my desktop. It's like a small handheld computer too, so you can do other things on it besides run Steam. Right now I'm using it to stream CraveTV to my TV since my Raspberry Pi streaming box isn't working.
Agreed on the insta-pot, I purchased one not too long ago. Was a bit skeptical on if I'd ever use it (I'm not what I consider a "good cook"), but I ended up using it all the time. My oven below my range barely gets any use now. Only hard part for me is keeping it clean, there's a lot of nooks that are hard to reach to get the grease off.
The only reason I haven't bought a Steam Deck is because I don't go anywhere where having a portable gaming device makes sense. I drive myself, and if I'm leaving the house I usually don't have any time to game anyway. I want one, I just can't justify the cost.
