Yes, this good
This was not our first cordless vacuum. We knew we were looking for excellent cleaning power, a long lasting battery and ease of cleaning. Tick, tick, tick. Great on all counts. Our Dyson has been relegated to garage duties.

Hard to push
Although I love the concept, I could not use it on carpeting. It was very difficult to push. Even the troubleshooting guide suggested it should be returned. I’m very disappointed.

Don’t waste your money or time
The absolute worst. I have had this 7 months now and it’s been a problem since day 1. Not good for hardwood floors, just blows dirt around. Hair constantly gets stuck in the wheels so I have to take it apart. I actually miss my Dyson. But honestly, this has just led me back to a broom and dust pan.

Making Vacuuming Fun!
Love the Shark PowerDetect ❤️ It has the auto empty bin which makes vacuuming actually fun! My husband and I were shocked at how much pet fur it pulled out of the carpet-I don’t think my old vacuum was really doing much. We’re Shark fans for life!!

Waste of money
I’ve had this for almost a year. So disappointing.. The pet hair attachment does nothing! The hair just gets stuck on the edge and doesn’t get sucked into the vacuum. It’s also really noisy, much louder than my Dyson.

Keep your money … not worth it
I have really tried to like this product.
Best features are charging station and self cleaning .
Boost power is very poorly designed and only gives a boost transitioning from hard floor to carpet.
Does not pick up well on hardwood floors.
I would return this if I could , but waited too late.
SO NOT WORTH THE MONEY.

Perfect vacuum
Best vacuum I’ve ever owned and is nowhere near the cost of its D———— predecessors. Have been using it for a few months now and love the fact that I do not have to get up close and personal with the dirt and debris. It is so easy to maneuver in small spaces and under furniture. It is well made, stores neatly and is always ready to go. It cleans up the whole place an...

Disappointed
I own Model: BU3521, and thought I would upgrade to this model to keep in a different area of my home. I love the convenience of no cord and vacuuming every day, so I figured since this had more features and it was more expensive it would be an upgrade. What a disappointment, I wish I had bought another BU3521. It's hard to turn on, it doesn't detect the flooring eas...

Hi Katie,
Thanks for taking the time to share your experience with us. We’re really sorry to hear that your Cordless PowerDetect hasn’t lived up to your expectations, especially since you’ve enjoyed your BU3521 so much. Turning the vacuum on should feel easy, floor detection should be consistent, and the vacuum should pick up effectively in both directions. We understand how frustrating it is when these features don’t work the way they should. We also know how disappointing it feels when the runtime drops too quickly while using power boost.
Even without the original box, we’d be happy to take a closer look at your unit and explore options to make this right for you.

This vacuum would be great if we didn't have pets! (We have 2 dogs and 2 cats) I have to stop every couple of minutes and unclog hair and debri that builds up on the roller brush. The only way it really sucks anything up is if it is in turbo mode. However, then the battery dies before I get half way through with the house ( our house is only 1300 sqft) I really wish ...

Hi there,
Thank you for taking the time to leave a review.
We’re really sorry to hear how frustrating this experience has been, especially in a home with multiple pets. We completely understand how disappointing it can be to constantly stop to remove hair from the roller brush, rely on Turbo mode for effective pickup, and then have the battery run out before you’re able to finish cleaning your home. That’s certainly not the convenience you were hoping for.
Your feedback about pet hair buildup, suction needs, and battery life is important to us and will be shared with our product team. We recommend reviewing the troubleshooting guide for your Shark POWERDETECT Cordless Vacuum, which includes steps that may help improve brushroll performance and efficiency when cleaning pet hair:
