Dyson cordless v10 and newer seems good. Got it when it first came out in 2018, I use it every day ( hardwood floors and lots of cat fur) and it's still going strong ( batteries didn't lose any power, runs like 50 min on low)

Got a buddy that got the V8 and it seems they have different battery types, since his losses power.

One thing to note, I got the corded Dyson dc23 like 15y ago, still works, and the cordless one cannot compare with it even in max power.

And I paid 750$ for it, because I purchased like 10 vacuums before, and they were all very very crappy, but after I pulled the trigger on a Dyson, I never regretted it. ( For sure they got better with time, but at the time Dyson was the best, and seems to still be up there with the best after so many years)
