## Description

Meet the new Shark Clean & Empty Cordless Stick Vacuum & Auto-Empty System. Clean & Empty features a redesigned 1.3L auto-empty base and a 30% lighter* stick vacuum, maintaining the performance of a full-sized** cordless. (*vs. IZ662H.) (**Based on ASTMF608, vs. IZ662H.) With the auto-empty system, cleaning convenience is optimized; Always Ready, Always Charged, Always Empty & ready for the next clean. The redesigned base holds up to 30-days* of dust & debris (*Based on ASTMF608, Eco vs. Boost.), so you can forget about emptying for up to a month and leave behind the trips to the trash can after every use. 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*. (*Based on third-party plume testing while emptying vs. manual empty.) Clean & Empty has up to 40 minutes of runtime with nozzle technology to auto-adjust 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 & directly engage hard floors with self-cleaning brushroll technology allowing for no hair wrap.

Review: 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.

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.
