Shark Clean & Empty – Lightweight Cordless Vacuum Cleaner with HEPA Filter, Powerful Suction, 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.

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

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 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.

This vacuum is a life changer! I had a vacuum with a cord before. I vacuum so much more now that I don’t have to plug in. The bristle-less spinner thingy on the roller inside is a game changer. I used to have to open up my vacuum and remove all the hair that winds up in the spinning wheel but no hair gets stuck around this design. Love it so much. Also the battery length is super sufficient. I have a 3,000 sq ft house and I can vacuum the whole upstairs and downstairs with one charge. It’s a mix of carpet and hard floors. Also, the vacuum actually works seemlessly between the rugs, carpets, and hard floors. Suction is great. Again, love this vacuum. Bought one for my 65 yr old Dad as well. Will buy one for my Mom next.
