Not ideal for families

Purchased this vacuum a little over a year ago. I think it would be a good vacuum for a single person or a couple with no pets. I think the vacuum has great suction and the concept of it is great. Unfortunately, I struggle with it working well for our family (5 of us) and our pets (dog and cat). It does fine sucking up the pet hair, but it struggles with the auto-empty (as other photos in reviews show, if the canister is more than half full it seems to not auto-empty). My work around has just been to empty it before putting it back on the auto-empty. The suction flap and the magnet for the auto-empty don't seem to work well. The magnet is constantly blocked by something, so typically before I vacuum I need to clean the magnet and close it manually. We did have a few instances where someone tried to vacuum up a wasp or a spider and the back flap wasn't closed, so out it comes. The battery lasts for about 30 min (enough for me to get one level of our house) - then needs to charge before I can tackle anywhere else. Now since it's been worked for over a year in our house, I can say with confidence that I wish this was a little beefier and could handle a family household. If it were just my husband and me, I do believe this vacuum would meet our needs. For a family, it will leave you frustrated.

Good concept however

At first we really liked this vacuum, the problem we ran into is if you don’t use it on a higher speed it doesn’t pick up anything. The battery time at that rate is about 10 minutes which is nothing when you have pets. The worst part it gets clogged constantly. The hair gets tangled up in the bottom of the brush. You have to clean the brush and the canister a lot. Also, the smell of any pets you have gets trapped and stays in the filter, you can clean it but that doesn’t stop it from smelling terrible. We have only used this vacuum in our brand new house for three months. I expected it to be better than that so that’s why I give it a three star review!

Disappointed

I was really excited buying this vacuum, I have a larger corded Shark which is terrific & I’ve also had an older model cordless which was great so I thought this previous experience along with the auto empty would be fantastic however I was sorely disappointed. The vacuum is terrible at picking stuff up even just on hard floors & I won’t even bother using it on the carpet I have to get the big one out to do the carpet, it get’s blocked up very easily (I have a chihuahua in the house) & it doesn’t last as long as they say it should maybe 15 - 20 mins. I don’t think I would buy another one

Features are great but not a great quality.

I bought this product end of last year. It was working really fine for a few months then started making loud noise and lost suction. I was given a replacement for the vacuum early this year. But now the same issue with replacement product. Nothing is stuck everything is clean, can't figure out what's going on. I like features in this vaccum compared to other cordless vaccum I have used. But now I am having second thoughts about this product.

Poor longevity

Bought this vacuum in Feb 2025 and I am already so disappointed. The suction is ok, at best. The canister has a little piece closed off and it collects the smallest dust particles that do not come out when it self empties. The roller and the clear casing around it is already DISGUSTING despite my best efforts to keep it clean. It doesn't pick up "debris," only fine dust and/or hair. anything bigger than a grain of rice is not being sucked up.

Don't fall for the 5 star reviews.

We have had this for about 6 months and regret the purchase 100%. The vacuum tube constantly blocks due to the diameter being so small, almost each vacuum it needs to be pulled apart a d have something pushed through the tube to clear the blockage. The attachments are useless as the suction is so poor, and the main power head won't pick up anything larger than .microscopic dust. Purchased from a third party so no returns, has been an absolute waste of money, don't fall for the 5 star reviews. Really disappointing shark do not reply or respond to any of the reviews, I find this to be poor business practice.
