About this item

Product details

Powerful Cordless Cleaning Solution

The Shark® PowerDetect™ Clean & Empty (IP3251) system offers the ultimate cordless solution for whole-home deep cleaning. Featuring Shark®’s most powerful cordless suction*, this vacuum is equipped with the redesigned DuoClean Detect™ nozzle that utilizes dirt-detecting intelligence and direction detect technology for superior debris pickup. Clean faster with forward and reverse debris capture, ensuring efficient and thorough cleaning.

Auto-Empty System for Convenience

Say goodbye to manual emptying with the Auto-Empty system that charges and empties your vacuum after every clean. This innovative feature locks away dirt, dust, debris, allergens, and odors for up to 45 days, keeping your home fresh and clean. (*Allergens refer to non-living matter.)

Advanced Cleaning Technologies

Shark® PowerDetect™ features 4x intelligent technologies that detect and react to your home. It automatically boosts power when dirt and debris are detected, tackles edges and corners, and adjusts to carpets and floors for optimal cleaning performance. The DuoClean Detect™ nozzle, with 2X brushrolls, is designed for all floor types and ultra-powerful hair pickup. (*vs. original DuoClean® nozzle)

Effortless Reach and Storage

With MultiFLEX® technology, cleaning under furniture is a breeze. The wand bends for easy access to hard-to-reach areas and folds over for compact, flex storage. Additionally, odor neutralizer technology guards against bad odors from debris, leaving your home smelling fresh.

Long Runtime and Included Accessories

Enjoy up to 70 minutes of runtime* in ECO mode, Shark®’s longest runtime yet, allowing you to deep clean your entire home. The vacuum automatically charges on the auto-empty base for continuous cleaning readiness. Accessories included are an 8” Duster Crevice Tool, Odor Neutralizer Puck, and Pet Multi-Tool for versatile cleaning needs. (*Tested at the hand vac.)

Don’t hesitate, just BUY THE VACUUM!!

I meant to buy this during Amazon Prime Week but it got sold out! I kept researching and researching this vacuum because I’ve been wanting it for months, and I finally found in stock at Walmart! 💙 Walmart is a lifesaver, AS ALWAYS! Back to the review… setting up the vacuum was really easy and I also watched a YouTube video to ensure I did it right. This vacuum is super light!!! It does take a little bit to charge, but it is definitely worth the wait! I love that it has 3 different settings and I especially love Detect mode that changes colors according to the level of debris it senses! This vacuum is very powerful and you can feel the pull when you’re vacuuming. It could easily zoom away if you don’t have a firm grip on it! 🤣 It really picked up all the additional debris that my old vacuum couldn’t! Imagine how long we’ve been living in that! I could really tell a difference after using this vacuum as the carpet felt super CRISP. I am so happy to have a cleaner, more breathable home. Also, the Auto Empty/charging dock is a game changer! It even comes with an odor eliminating puck that has a light and pleasant smell! I am so glad I finally purchased this vacuum and I know it will last a while. It really motivated me to clean and made the whole cleaning experience more enjoyable 😅👍

Works great, as advertised.

This vacuum is amazing. It's easy to operate, move around, and clean up. The self empty works flawlessly every time. And the base is easy to empty and clean once in a while. The edge detect, floor detect, and dirt detect all work like magic. Battery lasts a long time, easily do a 1500sq.f home and still have lots of charge left. I am quite sure this is a DC brushless motor. So don't worry about running it in smart mode like some customers have shown concern for, because the motor is constantly spinning up and down to adjust to floors and edges. This shouldn't be a problem for a brushless motor. Now the only thing remaining is that hopefully this product will last for a long time.... A of one month later, it is definitely recommended.

Long Hair? No problem!

So far I’m loving our new Shark PowerDetect™ Cordless Vacuum Clean & Empty System. We have a French Bulldog who sheds like crazy, and 3 long haired people in our house. This vacuum powers through all the hair, and it doesn’t get bound up on the roller at all! No more picking clumps of hair out of our old canister vac! The self emptying feature is very handy.
