Decent with one design flaw

I bought this vacuum in June 2025 and I have to say for the price I think there are better options out there. I love the empty feature and the auto detect is a nice feature. My gripe with this machine is that EVERYTHING gets stuck in the opening of the head. This really is a design flaw. Of course I try to pick up everything before vacuuming but with 4 kids and 2 dogs that is nearly impossible. And I’m constantly having to clear that opening. It’s frustrating and had I know I might have chose a different vacuum. I’ve never had it run out of battery on me and can go a long while before emptying the tank. Just wish the head was built differently. If you have no kids and purely dust on your floor I’m sure this perfect. But if you have a tissue or that hidden wrapper somewhere, good luck!

Sucks. And not like a vacuum should.

Constantly clogs with pet hair and stops running until I clear it. Hair wrapped around the barrel badly. Anything small vacuumed up and it stops until I clear it. Suction isn’t even comparable to other vacuums I’ve had. Only redeeming feature is emptying itself but that doesn’t make up for its lack of power. Two thumbs down.

Good vacuum but not great

The vacuum was great for the first 8 months I had it and now it barely sucks anything up. It just piles the dog hair and doesn’t suck it up. I cleaned it very well, checked for clogs, removed the hair that gets stuck at the bottom. And it does this on both carpet and hardwood floors.

Good vacuum

Great for small areas, stairs and corners. It has good battery life however has a very small dust collection tank and the rollers get stuck with too much dog hair. The automatic empty feature is awesome but it’s very loud.

Ok vacuum wand with awesome auto cleaner tank

Not as powerful as others are saying. I have dog hair on plank flooring that sticks to the plank flooring and it doesn’t pick it up. I’ve tried high mode and it’s ok but leaves clumps of dog hair from the rubber when backing up the wand. I do love the automatic cleaning out chamber! Works great.

Hi there, Thank you for taking the time to share your experience. Your insight into how the vacuum performs on dog hair across plank flooring is incredibly helpful. It’s clear you’ve put it through some real‑world use, and feedback like this guides meaningful improvements. It’s great to hear that the automatic clean‑out chamber has been a standout feature for you. As for the hair clumping and pickup challenges, your notes highlight an area where performance can be strengthened, especially for homes with pets and tricky flooring textures. Kind Regards, Shark Clean US.

Do not purchase!

Have had this for over two months now. I have to go over the same area multiple times. There is a trail left behind of particles the vacuum will not suck up. I find it very difficult to go from hardwood floors to a very thin rug to carpeting. The dog hair will stick if you will to the roller. I can vacuum two or three rugs and I have to stop and clean the entire vacuum before starting in a new area. The battery does not last enough to clean an entire level of living area. I have always been a fan of shark products but this is by far the biggest purchase regret I’ve had.

Good first impression

The vacum is as advertised, it's brand new so I can't speak to longevity. Works amazing, it pulls me on the carpet and does a fantastic job, wood floors great also. Sucks the dirt out haha with no dust etc, I really like this shark better than my old one.
