Inside the base, fine dust and debris get sealed away after every clean, leaving them out of the air you breathe-500x less dust exposure*.

Quiet but powerful
[This review was collected as part of a promotion.] This vacuum is just perfect. This is the one I grab when I need to do a quick vacuum. This grabs the dog hair off the floors and the carpet. It works on rugs as well. It even has a light so you can see what you are doing. The noise level is next to nothing, so it doesn't make my Mom's dog go crazy. I love the self emptying action. The collection bin holds a decent amount. The battery life is pretty good as well. I can do my living room, hallway, kitchen, and utility room areas and still have most of the battery left. By far, it's one of the best stick vacuums I've used.

    Best one for 2024
    [This review was collected as part of a promotion.] This is the best vacuum cleaner for 2024. The auto-empty system and self cleaning brush roll is the best feature that I could wish for. It has the strong suction on the floor and on the carpet. It automatically detects carpet and use high power. It is lightweight and easy to maneuver. It is loud but the work it does is remarkable. When you place back it on its stand it empties is small canister and all the trash goes in the bin which is attached to its home.

      Fav!
      [This review was collected as part of a promotion.] I’m so incredibly lucky to have gotten this! This is my new favorite gadget. It picks up so much hair in such a small time! It’s extremely strong when vacuuming normally and I love it. My only issue is how fast it fills. I have 2 dogs so it’s a lot of hair so I’m stopping more often but still worth it!

        Kinda not worth the money
        I have always liked shark products hair products. This shark vacuum keeps switching from hard floor to carpet when I'm trying to vacuum my carpet. I put in on the boost and it drains the power so fast. I have also tried to figure out how to clean the triangle shaped sand/dirt trap inside the clear big dirt collector. Very disappointed.

          Vacuum
          [This review was collected as part of a promotion.] The vacuum cleaner has made it easier for me to clean in areas where it is not so accessible to clean. Apart from that, it is perfect because it is cordless which makes moving with it easier. I recommend it 100% if you are looking for something practical and effective.

            Makes cleaning easy
            [This review was collected as part of a promotion.] Thank you for allowing me to test this awesome product! The process of putting the Shark cordless vac together was simple. I thought I might have to charge it,but it worked right out of the box. The suction is strong,and it won't miss a crumb,cobweb,or pet hair. Its light weight,and i noticed the sound didn't make my cats run for their lives which was a plus,but the most amazing part is when you dock it and it cleans itself!! Wow!! I love it!!

              This Vacuum really SUCKS… in the best way possible
              [This review was collected as part of a promotion.] I really love this Shark Vacuum. I’m no stranger to the brand and I can say that this vacuum really SUCKS, lol. The suction power in this model is incredible. It sucked up dirt I didn’t even know I had which was impressive. I really like the fact that the vaccum has its own auto empty system and cleans itself out. I will say when the dirt compartment is very packed and overfilled it might not empty into the auto empty base fully on the first time… but it’s no big deal to me. I just remove it and place it on the base again and it sucks out all the dirt. The light on the vacuum is awesome so you can actually see what you are vacuuming. My only complaint is that the vacuum is a little awkward to hold since the handle and battery are somewhat heavy but it’s really not a big deal at all. Overall I can’t ask for a better, more portable vacuum that helps me get my cleaning done quickly.

                Perfect household stuffing
                [This review was collected as part of a promotion.] This one has opened my mind. First, it looks fancy in white, that makes the house brighter. Second, the suction power is strong and can use on many different things as floor or mat… plus, it is noiseless, and love the dust storage which is can auto suck out the dust from the vacuum.

                  Empties Dust For You!!
                  [This review was collected as part of a promotion.] Oh my gosh. I cannot believe how cool this vacuum is. It empties the dirt for you!! It’s not loud, charge lasts, and it’s not heavy! I am very impressed

                    Accelerated suction
                    [This review was collected as part of a promotion.] I received this Shark Clean & Empty Cordless Stick Vacuum & Auto-Empty System as a compliment from Influenster for testing purposes. This Shark is lighter with hyper velocity accelerated suction power and its performance like a full-size cordless. It includes duster crevice tool and pet multi tool. It charges and empty after every clean. The auto-empty system is a plus for this vacuum however I gave it a 4 stars due to not practical and the power button location is not convenient to turn on. Otherwise it is a very good vacuum.
