Powerful and lots of helpful features
This is a powerful, light and easy to use vacuum. The stick has joints that can flex so you can vacuum under things that others can’t. It can temporarily get stuck on highly textured carpet but can be manipulated to work. I love this vacuum however, it is extremely powerful and can quickly plug the foam pre filter . The pre filter must be cleaned more often than you thi...

Do yourself a favor and just get a Dyson
I bought the Shark Cordless PowerDetect Clean & Empty System as a replacement for my old Dyson that finally gave up after many years of use. From the reviews I had read I figured that this would be a great cheaper alternative to a new Dyson with similar performance, boy was I wrong. If you have dog that sheds a lot, like a husky, this vacuum is not for you. The dust rol...

Best Vacuum for People with Pets
The vacuum is amazing! I have two black sister cats who shed like crazy. With my other vacuum (which I loved except for the cat hair issue) I could move side to side and rotate around - it was wonderful. But it would just roll the cat hair into long strips that no matter what I did the vacuum would not pick them up. It drove me crazy. The Shark picks up everything with ...

Great if you don't have rugs
I've been using this vacuum for a couple weeks and it's great, except on rugs. It automatically kicks up to high speed once I move from wood floor to the rug, sucks the rug up into the roller and then shuts itself off. I was really hoping based on the description it would work for my rugs, that was my primary reason for purchasing it, but it doesn't work.

Hi there,
Thank you for taking the time to leave a review.
We’re really upset to hear about the challenges you’re having with your vacuum, especially with it shutting off when transitioning onto rugs. We understand how disappointing this must be when your primary reason for purchasing the unit was to use it on rugs. While we’re glad to hear it’s working well on hard floors, we know that doesn’t make up for the issues you’re experiencing. Here is a link to our support page where you can troubleshoot and be guided to a resolution.

It works well on carpets and upholstered furniture. It does not work very well on hardwood floors. You have to go very slow on the hard surfaces - I end up going around with a broom to get corners which kind of defeats the purpose of having.a nifty cordless cleaner.

Hi there,
Thank you for sharing your experience with this vacuum. We’re really sorry to hear that while it performs well on carpets and upholstered furniture, it hasn’t lived up to expectations on hardwood floors. Having to move slowly, rely on a broom for corners, and deal with the dust‑bin latch popping open can be incredibly frustrating, especially when you purchased a cordless cleaner to make things easier, not harder. The short battery life on top of that only adds to the disappointment, and we truly appreciate you taking the time to explain what hasn’t worked for you. When an edge is detected, the headlights will illuminate on the side where the edge is sensed to help focus cleaning on targeted debris. If you believe the unit is not performing as expected, please contact us at https://support.sharkninja.com/contact-us so our team can review the issue and assist further.
Kind Regards,
Shark Clean.

Hi there,
Thank you for sharing your experience. It really sounds like this vacuum hasn’t been meeting the needs of a busy home with three dogs and two cats, and we’re truly sorry for the strain it’s putting on your wrist as well as the frustration of having to empty the bin so often. We appreciate you letting us know what hasn’t been working for you. To help improve performance, Detect Mode may be useful, as it activates Smart Detect Technology to adjust suction based on floor type, edges, and debris levels. Features like Edge Detect, Floor Detect, Dirt Detect, Direction Detect, and DuoClean Detect are designed to boost pickup, especially in homes with lots of pet hair. The included pet‑focused tools, such as the Pet Multi‑Tool and Motorized Pet Tool, may also help remove embedded hair and debris more efficiently. If you feel the unit isn’t working as intended, please don’t hesitate to contact us at https://support.sharkninja.com/contact-us so we can assist further.

Great Buy
The quietness of this vacuum is amazing and I t picks up great! I was concerned about the battery losing charge. We figured out it was best to let the sensors do the job. As long as the as getting is at the lowest or medium setting, the sensors goes back and forth. The highest setting will cause the battery to get hot and lose charge faster. That is a safety feature.

This is a total design disaster. Every time I put the vacuum on the station to suck the dust out, there are debris blocking the vacuum’s dust bin cap closing and leave the bin unsealed. You will see dust flying all over the place when you use the vacuum with the dust bin unsealed. Also the button to manually open the dust bin is sensitive(the bin is completely opened ju...

Hi June,
Thank you for taking the time to share this feedback with us. We are really sorry to hear about the experience you have had with your Cordless PowerDetect. We understand how frustrating it must be to deal with the dust bin not sealing properly and the debris escaping. The sensitivity of the dust bin release button and the placement you described should not be causing these kinds of issues, and we appreciate you letting us know what happened.

Everything about it
Well worth the price I have a Geman shepherd and a Australian ridgeback and leave dog tinsel everywhere. We use it everyday the convenience of no cord combined with the run time and power are unmatched. I have had other high end brands before and this works so much better. Also you gotta love the automatic container that eliminates all the dust.

Great features and easy to use!
Absolutely love this cordless vacuum, the clean and empty feature is great! I am a big fan of Shark products and this is by far the best purchase yet! It holds charge well and I can do my whole house with ease and I love the auto sense as well, it makes cleaning seamless when moving from hardwood to carpet. It vacuum's my shaggy rugs as well!

Good vacuum for pet hair
I like the lights that help show all the dirt/dog hair. Our dog sheds like crazy and this vacuum does a good job keeping up. I like that the arm bends to get under furniture. The head easily flips up into the resting position so 3-4 times while vacuuming our whole house I have to flip it back down. The auto-sensing suction is a bit delayed so I usually choose the mode ...

Hello,
Thank you for taking the time to leave a review.
Thanks so much for sharing your experience with the Cordless PowerDetect! We’re really glad to hear it has been working well for you so far. It’s great that the headlights and strong pickup are helping you stay on top of all that dog hair. We love hearing that the Flex arm has been making it easier to clean under your furniture. We also really appreciate you calling out the areas that could be improved, like the vacuum head shifting into the resting position and the slight delay with the auto sensing suction. Feedback like this is incredibly helpful as we look for ways to make the product even better. We'll be sharing this with our team, as it plays an important role in helping us improve and deliver better results for our customers. If you'd like further assistance with the auto sensing suction, please contact our support team using the link here: https://support.sharkninja.com/contact-us.

Love it!
I have only had this a couple weeks but so far absolutely love it! We are a ranching family so our vacuum gets a lot of dirt, straw, dust, not to mention dog hair from our 2 Aussies. It has been amazing so far. This was purchased to replace an older Shark cordless vacuum but I feel the PowerDetect makes a huge difference.
