I bought a Costco Shark before I got my Kenmore DU3017. It completely died in 3 months with no indication of what had failed so I couldn't even troubleshoot it properly. I was putting off contacting Shark to use their warranty when my dad convinced me to just take it back to Costco even though it was theoretically past their 90 day electronics return policy. Sure enough Costco took it back, and I hope to never have to deal with a new Shark product ever again. Oddly enough my parents have a 2015 Shark NV501 that is still kicking, but that could be because they hate vacuuming and do it probably once every other month.
I've got a Shark (and a dog - she's double coated and when she blows her coat I could build a whole new dog out of it) and absolutely love it. Gets up so much stuff and is light enough to carry up and down the stairs. And being able to lift away and use one of the small attachments makes hoovering the stairs really easy too.

I know shark is the devil on here but for $250 and under for a bagless machine either shark (a Costco one so you have kinda pseudo warranty) is imo best bet either that or a kenmore bagless I hear is decent too
I love, love, love my Shark. I bought it because it claimed that the roller brush was self cleaning and it's true. No hair ever, ever has gotten wrapped around the roller brush in the 5+ years that I've had my Shark. My previous vacuum (not a Shark) every month I had to use scissors and/or sharp knife to cut the hair off the roller brush but never once with my Shark. I love it. Best money I ever spent and it wasn't even an expensive vacuum.
I have the Shark Navigator with the self cleaning roller, but not the lift away version. It’s a few years old now and it’s still the best vacuum I’ve ever had and leaves no dog hair behind at all. We have carpet, hardwood, and rugs. There are settings for hard floor vs carpet and you can change the suction amount for things like rugs. And I don’t have to cut all the hair off the roller. Beats my previous Dyson Animal by a million and was nowhere near as expensive. Actually got it on sale pretty cheap! The canister is easy to dump and it’s simple to take apart to clean if needed.
I have a Shark Navigator with Self-Cleaning Brush Roll. I have long hair that gets everywhere. Have had this vacuum for 5+ years, and have never had to clean the brush. It's only about $200.
4th! Specifically the one with the self-cleaning rollers!
