With the auto-empty system, cleaning convenience is optimized so the vac automatically charges and empties when docked, staying Always Charged, Always Empty and ready for the next clean. Inside the base, fine dust and debris are captured after every clean, leaving them out of the air you breathe for less dust exposure. Clean & Empty has up to 40 minutes of runtime in ECO mode, measured at the hand vacuum, with nozzle technology that auto-adjusts to floor type, optimizing brushroll speed for deep carpet cleaning. The Powerfins multi-surface brushroll gives you continuous cleaning contact to dig deep into carpets and directly engage hard floors, and the self-cleaning brushroll technology helps prevent hair wrap on the brushroll.

Review: I am never going back to a regular vacuum! - I have always been a Shark enthusiast but now I am officially a self emptying convert. This vacuum has completely changed my cleaning routine. It’s so lightweight and easy to grab for quick messes, but the "Auto-Empty" system is the real game-changer. I used to hate the cloud of dust that happened every time I emptied my old vacuum, but this takes care of all of that for me. It picks up hair and desert dust from my Tucson floors effortlessly. No cords to trip over, no bags to mess with—it’s worth every single penny.
Review: You are going to LOVE this vacuum! Life Changing ... - While this may not be the right tool to use to clean up a box of Captin Crunch that has spilled off the counter all over your kitchen floor, this vacuum is life changing in every other way. Incredibly easy assembly; the head of the vacuum is the perfect size and flexibility to get in, around and under EVERYTHING. It picks up dust, pet hair, dirt, every little particle along the base boards and into the corners. When you're done you can SEE the difference and it is equally wonderful on tile, wood, carpet and rugs. The assembly plugs into a standard outlet so the unit is contantly charged and so light and easy to grab. I am DONE with heavy, awkward vacuums, clumsy cords and wasting time house cleaning with little visible difference. I LOVE the attachments that come with the unit and the empty system that keeps everything clean, neat and out of my way. Back to the Captain Crunch. It doesn't pick up large pieces of debris .. No worries - for that I use a broom and a waste bin, THEN the Shark Clean and Empty to make my kitchen perfect again.

### ⭐ I cannot even believe this is a Shark product
*by J***D on December 5, 2025*

This is the WORST vacuum I have ever owned. This is my 5th Shark vacuum but my first CORDLESS STICK Shark vacuum and I wish I would not have bought it. It CONSTANTLY clogs, the battery life is TRASH, you cannot get more than 10-15 minutes of vacuuming out of it. There is also a major flaw in the design for the auto-empty feature. The door to the debris tank has a magnet on it which is how the machine is able to open it to empty and close it when done without you doing anything beyond placing the vacuum on the charging dock. But the magnet is constantly catching debris and keeping the door from closing so if you do not catch it immediately, you will be vacuuming and empty the debris from the tank all over yourself at the same time. Between the clogging and the constantly having to recharge it before completing daily vacuuming, I just decided to stop using it as it was more of a hindrance than a helpful tool for cleaning my home. The reason I was unable to return it.. I bought this as a Christmas gift for someone else. By the time they had received it and let me know they did not need it, the return window had closed. So I decided to get rid of my older, heavier but very useful shark vacuum and replace it with this one being that I had never had a bad experience with a Shark product. Now that I am unable to use this one and cannot just buy the vacuum I want, I am using a much cheaper brand that I would not have chosen but still works much better than this vacuum. The concept of this vacuum is awesome but the execution was VERY disappointing. And I will never trust a “paid partnership” ad from Shark ever again.
