    So light and so nimble plus it cleans Itself!

    Posted by Raymond Morrison on Dec 3rd 2024

    Vacuuming at my house is a serious business. My house is a combination of hard floor and carpet areas and I have a couple of pets that shed tons of hair. In my quest to find the ideal vacuum cleaner, I currently own several types, from a Roomba style to a corded and two cordless cleaners. The Shark Cordless Clean & Empty Stick Vacuum is the newest and fifth member in my collection. Will it be the game changer I’ve been looking for? Assembly was simple and easy and it took less than an hour for the battery to fully charge. At first glance, the notable features of this product include its lightweight construction and sleek design; the handle housing the battery at the end looks futuristic. The machine fits snuggly on its base that also serves as a charging station. Using it is a breeze. The controls are neatly placed at the top and consist of an LED display for the battery level and cleaning modes and a pair buttons: one to turn it on or off and one to toggle between the cleaning modes. There are three modes: eco that saves energy, boost that prioritizes suction and auto that varies the power as it automatically adjusts to the floor type. The noise level is average for a vacuum cleaner, it gets louder on carpet in auto mode and when using the boost mode. It is very nimble and achieves quick turns in cramped spaces better than any stick vacuums I’ve owned, plus the lightweight helps even more. However, the best part is when I dock it to its base station, It whirrs to life, automatically emptying the dust cup into a dust container inside the base station that can be easily removed at the press of a button. Very handy especially since the dust cup is on the small side and quickly fills up with pet hair and dust. Another nice option is the quiet button on top of the base station that can be used in case you don’t want to empty the dust cup right away. Performance wise, the Shark Cordless Clean & Empty Stick Vacuum does a good job at cleaning. I always use the auto mode since I have a combination of carpets and hard floors. In auto mode, it switches seamlessly between surfaces and it’s noticeable by the noise level and the color coded light indicators for carpets and hard surfaces located on top of the floor nozzle. On both surfaces, I noticed that I have to do several passes until everything is picked up from the floor. Pet hair tends to stick to my carpets and it is the biggest challenge. With the floor nozzle, it took several slow passes to fully clean the area. I also tried the ‘pet multi-tool’ provided and it was more of a frustration than a solution. I have other vacuum cleaners that seem to have more suction power, but this one does the job in the end. One other minor issue I noticed is its tendency to come back to the stand-up position too easily while vacuuming; it might be due to its lightweight. I’ve only used it on floor surfaces and have yet to try above the floor with the crevice tool. I never had issues with the battery; it lasts with each use, even longer ones and since the cleaner is docked to its base station when I’m finished it immediately recharges, No complaints there. Overall, the Shark Cordless Clean & Empty Stick Vacuum is definitely worth considering for those looking for a good performing stick vacuum cleaner. Is it the game changer I’ve been looking for? No, but I truly like it for its impressive lightweight, great nimbleness and a battery that’s more than adequate. The self emptying and charging base station brings in some real magic and the modern looks certainly doesn’t hurt. I only wish it had a little bit more suction power to make it my favorite.

    Great upgrade from a wired vacuum

    Posted by Steven Zuniga on Dec 2nd 2024

    I upgraded from shark without a stand to one with a stand that automatically clean. It has great suction power and very convenient and lightweight to use just purchase so need some time to comment on the battery time but overall great looking product.

    Shark Clean & Empty Cordless Stick Vacuum

    Posted by Cindy Smith on Dec 2nd 2024

    I have to admit, I’m torn on how many stars to give this vacuum. First off, it has great suction and really picks up the dirt. The automatic brush roll had no problem detecting when I went from carpet to hard floors which is important because part of my floor is LVT and brush rolls can be rough on that kind of tile. But it seems pretty gentle when it slows down so I’m not too worried. I like the auto empty feature and the fact that it doesn’t empty into a costly disposable bag. Battery life is great, I can do the whole house on one charge (1500 sq ft). It’s light in weight and if you drop off the brush roll head and add the included accessory brush, cobwebs don’t stand a chance. Easy to clean them up one handed. The whole vacuum and base doesn’t take up much space and it looks good. The dust bin is easy to empty straight into the trash if you don’t want to use the auto empty base. So we’re looking at five stars just based on all that. Where it comes apart is the length, or more appropriately, the lack of length. It’s too short for me. I’m 6’4” but I usually don’t have a problem with length on a vacuum. I have to bend over slightly to use this. My other stick vac is about 3” longer and it’s more comfortable. It has several LED lights but they don’t seem to throw much light. Not a deal breaker since I generally don’t vacuum in the dark anyway. The other thing is see is a lot of flex where the wand attaches to the suction head. It just feels flimsy there. Not so confident that this won’t be a problem down the road. So I’m thinking three stars here. If I average it out, I’m going to give this vacuum four stars with an asterisk to try before you buy if you’re taller?

    More mobility with cordless! Plus it’s lightweight

    Posted by Brittney Grant on Nov 20th 2024

    First having a cordless household floor duty vacuum, major change in having a corded one that has its dust and debris compartment along with it. This is lightweight and has a separate emptying bin. You’ll have to make some trips to and fro the auto empty system depending on your floor situation. We do have quite a lot to clean up on living and bedroom floors and the kitchen tile. The auto sensing roll brush I think it’s a good feature that changes speed sensing the different floor surfaces whether hard surface or carpet. However just at a few times there are times when the LED indicator was on blue from purple (I think switching to hard surface from carpet mode) for a brief moment and I may have had the handle nearly at a 90 vs maybe at say 120-140 degree angle. There’s different modes to choose whether eco mode or boost; my default is just the auto mode for now. It lasts 40 mins on battery and on a full charge on the vacuum interface- shows four bars.. so I’d assume 10 mins each bar. I would like to get spare batteries and maybe a standalone battery charger if they do have such an accessory in the near future, which can double the time when cleaning a big house. But great product and Shark doesn’t disappoint.

    Smooth and Lightweight:)

    Posted by Pamela Lozano on Nov 12th 2024

    I have been using the Shark Cordless Clean and Empty vacuum since the day I got it, and it quickly became my favorite. It is easy to put together and comes with 2 additional attachments that are very useful for vacuuming in tight areas and for brushing couches. The vacuum itself is lightweight, making it smooth to use around my 1000 sqft home. It also auto-adjusts to different floor types, doing an amazing job on both tile and carpet. Even on my large rug, which my previous vacuum struggled with, the Shark vacuum performs excellently and doesn't get stuck. There's a tiny inconvenience with the small dust bin, especially for larger homes since it needs to be emptied more often. Additionally, when I purposely let the dust bin fill up to test its suction power, I found that it struggled to remove the trash on its own, requiring manual intervention. To avoid this issue, I now let it auto-empty every time. Despite this minor inconvenience, I still believe it does a great job of picking up all debris. A great feature is that all parts and filters are washable, and the bottom trash bin doesn't need a bag, making it easy to take off and dump out. The self-cleaning brush is a huge plus for me, as I hate cleaning stuck-on hair. The battery holds up well, even when running the vacuum at the highest speed, although that can drain the battery quickly. Overall, I am very impressed with its performance.

    The Shark cordless vacuum is an awesome cleaning machine! It sports an auto empty system, is lightweight, easy maneuverable and offers an auto sensing brushroll which adjusts to various floor heights and carpeting. ?? The vacuum is lightweight, weighing in around 12 pounds. Since it is so lightweight it is highly maneuverable. It has an auto-empty base which according to the manufacturer holds up to 30 days of dust and debris. LED headlights on the vacuum head help illuminate dust and your targeted cleaning areas especially in those dark corners of one’s home.

The auto-adjusting brushroll automatically adapts to different floor types optimizing cleaning performance all by itself. ??It has approximately 40 minutes of runtime which should be more than sufficient time to vacuum your entire house without a recharge. My home is approximately 1750 square feet and I had plenty of battery to vacuum my entire house with recharging. One of my favorite features of this product is the auto-empty system. When vacuum is placed onto its doc, it auto empties and charges itself making itself ready for your next cleaning session. ??The vacuum has a Hepa filtration system which is designed to reduce dust exposure which is a big plus for those consumers suffering from allergens. Overall, the Shark is well-suited for those looking for a convenient and efficient cordless vacuum with advanced features like auto-emptying and adaptive brushroll technology. The Shark cordless vacuum is a versatile and convenient cleaning machine, which is fun to use. With its advanced features and ultra modern design, it’s sure to be an hit with consumers.

    Shark Auto Empty

    Posted by Amanda Bell on Nov 11th 2024

    I enjoy it so far. Battery has lasted even when I’ve vacuumed my entire downstairs. The suction is great, and the auto empty is convenient. I have noticed that sometimes when the vacuum is auto emptying hair or thread can get stuck in the flap of the vacuum when it closes. This isn’t a huge deal though because the flap is easy to lift and remove whatever is stuck there. Overall a great product. Will see how it holds up over time.
