Clean & Empty Cordless Stick Vacuum – Lightweight Cordless with HEPA Filter, Portable, Rechargeable, Auto-Empty System, Stick Vacuum for Pet Hair, Carpets & Hardfloor, White, BU3521

This vacuum works really well and motivates me to clean my hardwood floors more often. I’ll start by saying this vacuum was such a welcome surprise to my previous one. I bought this to replace an all in one mop vacuum combo from another brand that really delivered poor performance so this one totally outshined the competition. 1) it’s really powerful. I can vacuum multiple times in the same day and it will still collect stuff and it’s chamber that will impress you to see how clean it’s keeping your floors. 2) great battery life. I absolutely love that. I can just keep it on. It’s charging stand, which means that I can pick it up anytime quickly and easily and I know it’s going to be charged and ready to go. When I’m done, I just put it back on its charger. 3) the self cleaning function!! I wasn’t looking for a vacuum with the self cleaning function so that was just an added bonus. I really didn’t think I would care about it, but it is SO NICE TO HAVE. Having a vacuum with a self cleaning function that empties the dust bin for you means that anytime you want to vacuum you simply pick it up off the charger and when you’re done? You simply put it back on the charger, that’s it! It makes it so quick and easy to vacuum (and bonus it’s pretty fun to watch) which means I vacuum more frequently and actually look forward to doing it! 4) the roller brush doesn’t trap hair, thank GOD. I truly despise dealing with hair that isn’t on my head it just grosses me out. I also have 3 pets so not having to deal with cutting hair out of a brush after vacuuming is a literal godsend. 5) pivots from hardwood floors to rug easily. It has an auto detect feature that will automatically increase the suction power when on a rug, which is really nice. 6) the buttons for the attachments feel really nice to click on and off. You know when you have a cheaper product and you feel like you’re almost going to break it to click something or push a button? This is easy to put on and take off attachments and feels like it’s nicely made. And it was a big plus for me that it has a handheld feature that can be removed for vacuuming things like the couch or car. 7) it has three suction power modes; Eco regular and a turbo mode, which gives you more control on battery life if you need it to last a little bit longer but don’t need quite as much suction power. My space is only about 1200 ft.² so I’ve had no issue with battery life. Some constructive feedback I would like to include: 1) it would be nice if it could stand up on its own 2) it can’t lay totally flat, though it can go pretty low and get a little ways underneath the bed 3) Lastly, Shark, can we talk about the aesthetic of this thing? I’m not going say that us women are the only ones vacuuming out here but a lot of women are going to be buying this product and we do not want a vacuum that looks like a drill handle 😂 I was honestly very put off by the way this looks when I first saw it, but the functionality of it made it worth it. I would LOVE to see a nicer looking handle for the future.

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.

I bought this vacuum in May 2025, so it’s not even a year old yet. At first, I really liked it. It had strong suction and handled our large townhouse well, especially with all the stairs. It's very lightweight which made cleaning way less of a chore. About a month ago, the handle suddenly broke. The connection point just gave out and all of the wires inside were exposed. It honestly looked like a very flimsy design where the handle connects. We had to wrap the entire area in duct tape just to keep it together and keep the vacuum functioning. I contacted Shark customer service two weeks ago. They told me the replacement part wasn’t available and that they don’t do backorders, so I should call back in two weeks. I called again today and was told the exact same thing. Still not available. Call back in another two weeks. For a vacuum that is less than a year old, this is unacceptable.. save your money and go with a different brand.

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 really like the Shark Clean & Empty Cordless Stick Vacuum overall. The suction is strong, it’s lightweight, and the hands-free empty feature is super convenient especially for quick cleanups. It does a great job picking up everyday messes. That said, I do wish the battery life were a bit longer, especially when cleaning multiple rooms in one go. Also, with dog hair, the hands-free empty can occasionally get jammed and needs a little extra help. Even with those minor issues, it’s still a solid vacuum and has made keeping up with pet hair much easier. I’d definitely recommend it, especially for daily use and quick cleanups!

Es muy práctica al poder cambiar el tamaño al intercambiar los módulos. Bastante potente. Muy recomendable.

أنصح فيها

As a user of proper vacuum cleaners I was skeptical about cordless vacuum cleaners. Unfortunately my experience proved true. As soon as I got it I tried to vacuum a strand of hair and wouldn’t come. I felt like I am holding a fan not a vacuum. I tried vacuuming the tiles, I had to go over the piece of crumble four times to pick it up. Then I tried to vacuum my carpet, the vacuum showed red light and shut off and the battery which was full became zero. This is a toy not a vacuum.

I am very happy with my recent purchase! It's incredibly light and easy to use. I particularly appreciate how it automatically adjusts its power based on whether I'm cleaning a floor or carpet. What I love most is the stand station. It's so convenient not having to fix it to the wall, and the auto-cleaning feature is a fantastic bonus. Beyond these features, the 5-year warranty speaks volumes about the quality of this product. I absolutely recommend it!

Amazing same as description.Work perfect very light but same time very strong
