Shark Pro and Detect, I need a vacuum for a condo. Is it worth it?

For quite some time, I have been wanting to get a cordless vacuum. I did some research online, but wanted to see firsthand what the real difference would be between a corded and a cordless vacuum when used on carpet especially since my old vacuum is six years old I thought in six years cordless vacuums would be a lot better. Some of my local stores had similar models, but I figured I would pick one up from my local Costco given the return policy, it was 280 plus tax. I live in a small 800 square-foot apartment that’s 80% carpet with a small dog that doesn’t shed too much, but I always have the windows open which lets a lot of dust in. My old navigator I bought at Macy’s for $100 on sale it does not have a HEPA filter. Originally I wanted the cordless one so that I can get into places that my old navigator couldn’t get into since it’s not the lift away model. I used the cordless vacuum to do a first pass-through the entire apartment before going over it with the old navigator as you can see by the pictures the old navigator picked up a lot more that was left by the cordless vacuum. I will say I was surprised that the shark cordless model even picked up the amount it did given that I vacuum twice a week, but it’s still amazing that a six year old model that I’ve never had issues with thankfully was able to pick up a lot more. at this point, I think I might be returning the new one and just picking up the lift version of the shark corded model. I’ve seen some of them for around 150. I’m gonna try it out for another week.
