Hi all, I've been doing some research into which bagless upright vacuum to get.

To give a quick rundown of my situation:

• ~650 sq. ft. apartment.

• The flooring is all hardwood except for tile in the bathroom, with a few small low-pile rugs (kitchen mat, bath mat, under chair — not a big concern at all).

• I have a very furry cat that sheds a lot. The hair is so fine that you literally can't even tell it's there until you sweep a large enough area for it to build up into a pile.

I already have a Roborock Q5 Pro running daily, but I still end up with cat hair stuck to the bottom of my socks at the end of the day. So, this is primarily what I'm trying to target.

I;ve read through plenty of threads on this sub and understand that everyone believes bagless vacuums are terrible and so are the common consumer brands like Shark, Bissell, Hoover, etc. However, I like the features these models offer and I've personally had good past experiences with Shark. And, if I buy from Costco, I know I have extra protection in case something goes wrong in the future.

With all that said, I'm looking at these 3 Shark models:

• Shark DuoClean Lift-Away Upright Vacuum with Self-Cleaning Brushroll (UV700)

• Shark Navigator Lift-Away Upright Vacuum with Self-Cleaning Brushroll (UV725)

• Shark Performance Plus Lift-Away Upright Vacuum with Odor Neutralizer (UV900)

However, I can't really tell what the differences between them are and which one would be best for my use case. These seem to be Costco-exclusive models so I can't find much about them online and the descriptions aren't very helpful.

• It looks like the DuoClean has two bristle brushes, the Performance Plus has one rubber brush and one bristle brush, and I assume the Navigator only has one combo bristle/rubber brush. I've read that bristle brushes may be better for picking up pet hair, at the expense of being more difficult to clean.

• The attachments are not a concern. They all look good enough to me and I seldom use them anyways.

• I do like the idea of the odor neutralizer functionality on the Performance Plus since the apartment does have a bit of a cat smell to it, but I assume it doesn't make a massive difference.

• Finally, price is not a concern. Just looking for the best one out of these 3.

I did also look at the Dyson Ball Animal 3+, but found a few comments saying that it was worse than Shark. I'm not too big of a fan of the ball design (seems like it would be hard to fit in certain areas) and don't like that it's missing LEDs/laser. However, if it is in fact better than the 3 Sharks, I'll definitely consider it again.

Can anyone advise? Thanks in advance.
