Customer Ratings & Reviews

This vaccuum is lightweight but capable. The self emptying dock is awesome and functional. The smart sense in the vaccuum head actually works and changes the motor speed / force when switching from our hard floors to the carpet in the office. The battery more than lasts for a conplete sweep of the main floor (roughly 1000sq ft) and only goes down about 20%. We have three dogs that love to play outside and, frankly, bring the outside inside. It handles it all.

This vacuum exceeded all expectations. We have a fluffy dog part german shepherd and the amount of fur is crazy. This vacuum gets used 2 to 3 times daily. Flat surfaces it will run longer. When Ivacuum carpet its about 15 minutes of solid vacuuming before battery runs down. Tile and lvp floors it will run 20 to 25 minutes. Literally the only down side to this vacuum is a design flaws that most have complained about in other reviews. Inside the dirt/dust collector is a wierd plastic piece that small micro dust gets collected in. Especially sand. (Because Florida) Well thats great if you could empty the small section. Its trapped. One way in and no way out. Ive had the vacuum almost a year and that small plastic pocket is still full, no way to empty. It doesnt hurt the overall functionality its just annoying and an eyesore. Overall even with this known issue this vacuum has been a lifesaver. This was purchased to use as a lightweight mobile alternative after a surgery.

Very light weight and glides super easily. I love the fact that there are 3 different speeds and there's no need to change settings for different floors. The vacuum senses when vacuuming carpet and hard flooring automatically.

The vacuum functions really well, and i have no complaints about it or the empty system. However, there is a really odd feature in the cannister that catches dust and dirt. However, there is no way to empty this and clean it out. You just have a permanent and annoying monument to the vacuuming you've done. Still recommend, but this design choice has me questioning that.

Works great, super convenient and mess free. I use it almost daily with a small pet in the household with hardwood and rugs so hope it lasts! Also looks nice and discreet in its mount.

From my wife : This vacuum is amazing!! I love how light weight it is and its maneuverability. The way it empties itself into the larger container seems so futuristic and is much easier to empty than other vacuums. The removable roll brush for easy cleaning is also a favorite feature. I’ve recommended this vacuum to my family and friends.

Hair doesnt get stuck so much like the previous shark vacuum. I still keep the previous shark as a back up and for certain accessories this one didnt come with. Like an extended tube attachment for vacuuming the car, corners, or other areas a but difficult to reach. Its still too early to say if i like it better than my old one but i am certainly enjoying some of the new features like auto clean ejection and im still learning how to use it. Charging is different. Instead of 2 battery packs charging by a cable you just have a little station you set it into and it charges instantly. Overall good for a small house. Clean my carpet really good at getting the dust out

Great vacuum with a self emptying option. Light weight, easy maneuvering, and good battery life. Worth the price.

Got this on Black Friday and gave it to my mom for Christmas. The auto adjust feature is nice because we have hard wood floors but then rugs throughout the house. We have 3 dogs who shed a ton so cleaning the floors is quite the task. Hopefully it will hold up well. So far she is very pleased with it!

Our bObsweep Ultravision (whom we've lovingly renamed Vision, because obviously) has been a total game changer for us and our home. We have a dog whose full-time job is to shed hair, constantly, everywhere. I just couldn't keep up with daily vacuuming and dust-mopping, and I was distressed with not being able to keep our floors clean. Enter Vision: this little robot who is now my BFF runs every day without complaint and keeps our floors tidy. He is so good at navigating around objects, including my teenager's shoes and other random things she leaves around. He finds the edges and corners so there are no missed spots. Vision isn't silent, but he's not obnoxious either. The auto-empty is incredibly convenient as well, and I love the mopping feature - just a simple wipe of the hardwoods makes such a difference. I'm thrilled with Vision and am so glad he's part of our home!

Excellent for quick clean. Even for vacuuming Window AC unit filters.

Pros: Light weight: about 6 lbs. Stand weighs 6 also Easy to use and assemble Can use accessory for counter cleanup Good for small space Cons: It won’t pick up large onion papery onion peel It won’t be as effective when vacuuming downstroke

Love it, battery it’s the best but I don’t have a big place.

Amazing vacuum works really well. We use it everyday.

Very pleased with this Shark vacuum, it works really well and does not look out of place sitting out in the charging station. Like the fact that it self empties after use and bin is easy to empty. Recommended

The Shark Clean & Empty cordless stick vacuum is a great option if you have a small to medium size home with a mixture of floor types. The auto empty feature works great and combined with the light weight and auto-sensing, auto-switching floor brush makes for fast and easy vacuuming of dust, dirt and other debris on your carpet and hard floors. The brushroll also includes Shark's anti-hair tangling feature; I frequently have longer strands of hair on my carpets and floors and over three days of use, the brushroll did not accumulate a noticable amount of hair. The auto-empty bin is "bagless" and the filters are washable, which eliminates the need for recurring supplies purchases. The suction power is ok - not as strong as my full size, corded stick vacuum or some other cordless models I've tried, but the light weight and easy manuverability makes up for the lesser power for my needs. The suction may not be strong enough to pickup embedded dirt and hair if you have deep pile, thick carpet. The debris/dirt bin in the vacuum is also small, but fortunately, the auto-empty feature works well and quickly to empty it. The auto empty cycle automatically starts every time you put the vacuum back onto the cradle, but it has a "quiet" mode to disable the auto-empty in case you don't want to have the noise (it's not as noisy as my other auto-empty vacuum). The two negatives I marked the vacuum down one star for are the lack of a place to store the included multi-tool (there is a spot on the dock for the included crevice tool), and the power cord for the dock is relatively short (approx. 4 ft.) which complicated my placement of the dock in my home.

The fact that it empties itself is convenient but it has been barely over a month and the cheap plastic handle which is hollow and thin broke! My wife was vacuuming and all of a sudden calls me over all upset because the handle was snapped in half with wires showing. Im not sure if maybe ours had taken some damage in shipping or if the handle just happend to be compromised somehow but for something that you are supposed to push arround, turn and lift (with attachement) to reach corners, you would expect the handle to be reinforced or a little mor solid but after seeing the inside its not very thick at all. My wife has other opinions and preferred our older shark vacuum vortex something or other over this one but i tried to defend it because i kiked that i didnt have to empty the canister so often and it seems to get clogged less but i expected to last more than a month and change. Not sure what to do here but for now i taped and glued it hoping it can hold hntil i get a replacement but not sure what i can teust anymore. This wasnt a cheap vacuum to be breaking so easily!! Ill happily change the review if I had a model that lasted longer because it could easily be 4 or 5 stars not for the flimsy handle.

I’m extremely impressed with the Shark Clean & Empty Cordless Stick Vacuum. The suction power is excellent, even on thicker carpets, and it transitions smoothly between different floor types. The cordless design makes cleaning so much easier—I can move around the house freely without constantly plugging and unplugging. What really sets this vacuum apart is the 1.3L auto-empty feature. It empties itself quickly and cleanly, which is a huge time-saver and keeps the dust bin from getting messy. The runtime is solid, and the vacuum stays powerful even as the battery gets lower. It’s lightweight, easy to maneuver, and the cleaning head fits under furniture with no problem. I also appreciate how quiet it is compared to other models I’ve owned. Overall, this vacuum has made my cleaning routine faster, cleaner, and more efficient. Highly recommended!

I have been a user of cordless “stick” vacuums for the past five years and find them to be just as good at cleaning and way more convenient to use than their corded and heavy counterparts. This Shark Clean & Empty cordless vacuum (model BU3521) is billed as being an “ultra-light cordless” that also utilizes an “auto-empty system” incorporated into the charging stand that holds the vacuum when not in use. The vacuum can be used as a floor vacuum utilizing a long wand with a powered nozzle that contains a motorized brushroll with lights, or as a hand vacuum without the wand but with the nozzles attached directly to the handheld vacuum unit. This model came with a motorized floor nozzle, a crevice tool, and a “pet multi-tool” in which the brush snaps on and off of the tool. The auto-empty system activates each time you hang the vacuum on the charging stand (AKA dock), with the dirt and debris being sucked out of the dust cup on the vacuum and into a larger dust bin at the bottom of the dock base. This larger dust bin is just that, a container without a bag like some other systems use. The nice thing is that you empty this large bin much less often as opposed to a vac that has to have its small dust cup emptied every time you use the vacuum which usually creates a small cloud of dust that doesn’t all end up in the trash can and potentially in your face. The auto-emptying feature happens each time you hang up the vac on the dock so that it is ready to go the next time you need to use it, but there is a button to defeat this feature. This is in case you don’t want the noise the dock motor creates when it sucks the debris from the vacuum’s dust cup, such as late at night when it might disturb others in the household. This button has a moon-shaped icon on it to denote nighttime use and the “moon” illuminates when this quiet mode is engaged. The dock charges and stores the vacuum in addition to emptying the vacuum and storing the debris. Full charging takes about 4.5 hours according to the manufacturer. There is a prominent light on the battery that glows green when it is fully charged. The wand needs to be attached to the hand vacuum in order to charge as the electrical contacts for charging are at the top end of the wand. The hand vacuum can be used without the wand and floor nozzle such as when cleaning furniture. The battery is removable and has a charging port on it to accept a cord from a charger. This type of charger is not included with this vacuum, but appears to be available on Shark’s web site along with additional batteries (I consider the battery price to be reasonable when compared to batteries for power tools). The charging dock, with the vacuum in place, takes up an area about 11” x 15” on the floor. The overall height is 43.5”, but overhead clearance of 46” is needed to get the vacuum on and off the dock. The dock provides tool storage for only one of the included tools, the crevice tool. There are two other tools available for purchase from Shark according to the owner’s guide, but unfortunately, a hose is not one of them. The full owner’s guide is available as a downloadable document only and the only paper documentation that comes with the vacuum is a Quick Start Guide that includes maintenance information and safety warnings. During use, the Cordless Clean & Empty vacuum is light and easy to maneuver. Sometimes a little too easy to maneuver as it glides over hard-surface floors with very little resistance. The powered floor nozzle which will undoubtedly get the most use by owners, has a couple quirks that are unique and may take some getting used to depending on the vacuum you were using in the past. The LED lights are mounted at the top of the nozzle above the large brushroll and the light seems to be directed to the floor via the clear plastic housing. This angle does not illuminate debris on the floor quite as well as lights mounted down low on the leading edge of the nozzle. The articulated joint where the wand meets the head forces the head to always swivel left and right as you tilt the handheld unit from side to side and this limits your ability to steer the floor nozzle under furniture and around legs, thus limiting your reach under some obstacles. Also the floor nozzle will “lock” at a 90 degree angle to the wand if you accidentally pull it too far back towards you and this feature accidentally engages. That means you have to place a foot on the nozzle to snap it free from the locked position so you can continue vacuuming. The controls on the handheld motor unit consist of two simple buttons, one is on/off for power, and the other cycles between Auto mode, Eco mode, and Boost mode. Eco mode provides sufficient suction power for non-carpeted floors and it also gives the longest runtime. I found the amount of suction generated is on par with competitors (I have no way to quantify this performance though) and I found vacuuming to be relatively easy on low-nap carpet. When you transition from hard flooring to carpet in Auto mode, the vacuum automatically senses this and increases suction and RPM speed of the brushroll. If you are on carpet with a deep pile, this increase in power can make the vacuum very difficult to push and pull. The Boost mode offers greater suction power, but I found that this is of little value on carpet because of even greater resistance to moving the vacuum. I found no need to manually switch to Boost mode on hard-surface floors, so I suspect it may be best used on furniture while using the crevice or multi-tool. The powered floor nozzle has some ingenious, short tines that keep long hair from wrapping around the brushroll and they do work as my wife leaves a lot of hair on the floor and I found none encircling the brushroll after cleaning the house, like I have in years gone by with other vacuums. The brushroll and filters are very easily removed without tools for cleaning. All of the filtering media in both the handheld vacuum unit and the charging stand, are washable with plain water (do not use soap) when needed. It appears from the literature that the main filter in the dock is a HEPA filter and the one in the vacuum itself is not - as far as I can tell. The vacuum comes with a five-year warranty (two years on the battery) which is pretty amazing considering the price point of this vacuum. Having a cleaning tool that is easy to use can make home chores more pleasant - I will stop short of saying fun - and the Shark Clean & Empty is about as good as it gets for this. If you are tired of lugging around a big, heavy, inconvenient, corded vacuum, you owe it to yourself to try a modern take on an appliance that has been around forever and see just how much better the experience can be.

Horrible build quality. $300 vaccum that feels like we got it from a Dollar Store. The handle snapped clean in half. Good luck calling Best Buy for any support! They’ll just give you the run around and tell you to make an appointment
