    Excellent Vacuum, Short Battery Life

    Picked this up looking for a cordless vacuum with a decent battery life, while also finding something to deal with the excessive pet hair my dog and cats produce. I have hard wood floors, with area rugs spread throughout the house. The carpets get gross and full of hair, and the hair that doesn't end up on the carpet blows around the house like tumbleweeds until it gets lodged in a corner or under furniture. Drives me crazy. This vacuum achieves most of my goals I set out with, but the battery on this is not great, and that is my biggest gripe with this item. This vacuum is nice because it does do a good job on the pet hair on the carpets, and obviously the cordless feature is always nice because I can take this wherever it's needed without worrying about if it will reach with the plug or if I need to unplug and move to a new outlet, or if I am getting tangled or stuck on things while vacuuming. Setup was easy. It does come in quite a few pieces unassembled in the box, and at first glance it can seem a bit overwhelming, but luckily there are plenty of stickers on the pieces, and a very helpful manual that tells you where to start and what goes where. Everything is click into place, which is nice. I like that the bottom of the vacuum, the roller part, comes un-attached so you can use the stick to get suction in corners. There is also a button on the middle stick section that makes it "bend" if you will, so that it can easily fit under couches or benches or other furniture that may usually be hard to get under. That is a nice feature. This also comes with 3 cleaning modes, a Clean Sense IQ mode, which basically "adjusts" to what it's cleaning. It starts in a low power suction, and then say you run into a giant clump of hair, or debris or cereal or whatever, it will auto kick in to a higher suction mode to account for the power needed. This is a great feature as well. The other 2 modes, are standard a high suction mode "full blast", and a lower power "eco" mode which gives really slow suction, but this may be viable for most situations. Also has a nice vibrant display that shows you how much battery life is remaining which is helpful. The main issue, which I touched on, is the battery life. Regardless of what "mode" I picked, I still only got about less than 30 minutes of power. Now, in most situations you don't need anything more than this, and that's something I factored into my review. This will do all the jobs you need it to. BUT, after the battery dies, which was most confusing to me is that the battery would take HOURS to recharge. Like I plug it in at 2pm, and then at 6pm it's still not fully charged. Seems like it shouldn't take THAT long to charge. Especially for only providing 30 minutes of power. I have a small house. If you have a large house, with multiple rooms to vacuum, you have to plan to split it up apparently to get it all done. I would still however, recommend this product. Although the battery life leaves something to be desired, the product itself is excellent and good with pet hair.

    easy to assemble and easy to use. storage need is very small for this vacuum. does well in vacuuming! only downside is the weight is in the handle so this could be an issue if looking for a very light weight vacuum to use. I have vacuumed more with this vacuum than I have in quite some time.

    With 2 very fluffy dogs we tend to go through vacuums rather quickly. We prefer these light weight stick vacuums like this Shark - Stratos Cordless with Clean Sense IQ. It is very light weight to carry from downstairs to upstairs. The only drawback is the dust cup on these light weight vacuums fill up quickly, especially when you have pets. The setup is very easy as with any stick vacuum. Attach the wand to the roller body at the bottom and the dust cup and motor assembly on the top. One difference with this Shark - Stratos Cordless Vacuum is that it has an Odor Neutralizing Cartridge which adds a fresh scent to the air and carpet as you vacuum up the dust, dirt and hair. I really like the fresh scent and will buy more cartridges as needed. The motor of the Shark Sratos is by far the best of any vacuum we have owned. There is 3 settings, Eco, clean sense IQ, and Boost. The clean sense did well. It added power to the suction when it sensed a dirty area but if you really want to get deep down dirt out put it in boost mode (or as I say, "Beast" mode) and really feel that suction. I ran it on Boost mode at 100% battery life and was down to 25% after vacuuming our living room, family room, and bedrooms. There wasn't a strand of dog hair left anywhere and the 2 rollers stayed hair free unlike previously owned stick vacuums that end up with a huge hairball after each use. As I said though the dust cup is small so I had to empty it 4 times while vacuuming those rooms. I tried the Stratos out on our hardwood floors also and it did very well. Usually a vacuum will shoot particles of debris around the floor when you try to vacuum hardwood but not this vacuum. It adjusts the roller speed automatically to gently pick up particles on hardwood and not shoot them out the back. Besides the beast mode suction the position you can fold it into for storage is the best part. Just press a button on the stick and you can fold the dust cup and motor part of the vacuum forward so it sits balanced and with a very tiny footprint. You could store this easily in a closet, under a table or even out in the open because it gets so small you would barely recognize it's a vacuum. We love this Shark - Stratos Cordless with Clean Sense IQ and hope to get many years of hard work out of it.

    Dynamic and Vigorous Cleaning

    This is absolutely the best cordless stick vacuum I've ever used. The Shark Stratos Stick Vacuum uses its clean sense technology which automatically increases suction and brush speed to pick up all of the dirt and debris in my rugs, bare floors, and everything above the floors. The vacuum came with two attachments. I used the two attachments to clean my steps, the areas between the spindles on the steps, the floorboards, and the ceiling fans. I even used the attachments to clean the rugs in my car. The excellent deep suction and brush speeds cleaned all of these areas with ease. There are three mode settings in this vacuum. There is the Eco Mode, the Power Clean Sense IQ mode and the Boost Mode. The Eco Mode saved the vacuum's battery life. The boost mode delivered maximum suction but drained the vacuum's battery faster. I found that the best balance between suction and power with optimized battery run time was to use the Clean Sense IQ mode, which is actually the default setting for this vacuum. It was amazing to see the infrared sensors detect the dirt and automatically adjust the suction power to pick it up. I used it to clean under the furniture using the Multi-Flex wand by just unlocking the quick-release latch on the wand. The excellent LED Headlights helped me guide the vacuum through dark corners and closets. This vacuum comes with an Anti-Allergen with a complete seal and HEPA Filtration. It also comes with Odor Neutralizer Technologies. I vacuumed my entire home in about 40 minutes. Once done, I emptied the dust cup by simply removing the hand vac from the wand before emptying it into the trash bin by pressing the one-touch release button. I found that the vacuum cleaned dog and human hair that was not visible while I was vacuuming. The DuoClean Power Fins Hair-Pro self-cleaning brush roll did an excellent job. The vacuum had some battery life left after working continuously for about 40 minutes. When I was done cleaning, I simply folded the Multi-flex wand and charged the battery for storage.

    I absolutely love this vacuum. I will admit, I’m comparing it to the Dyson stick. I have 3 dogs and vacuum every single day. Every single time I use this, the amount of dust and hair it gets in unmatched to any vacuum I’ve ever used. I cannot suggest this vacuum enough. I feel like our air is constant dust free with the amount of dirt and dust it gets up!!

    I've had nothing but issues with this thing. I bought this vacuum because it was supposed to be great for pet hair and hair not being able to get tangled in the brush. Before the first month was up it quit working properly and was givi g a code, so I contacted Shark for troubleshooting and they said the body was malfunctioning and they sent me a new body. Ok, fine, that part was fixed so on to the next issue. I have a white german shepherd and anybody that knows shepherds know they shed twice a year and each shed lasts 6 months each. She is mostly an inside dog, so I need to vacuum almost daily and needed something more convenientthan my big vacuum. The hair gets caught in this comb like feature and mever goes into the vacuum chamber. As I trying to clean my rugs and pull the vacuum back, the hair spreads back onto the rugs in clumps. I am so disappointed and hate the fact that I paid this amount of money on something so useless.

      Hi Cindy,

      Thank you for sharing your experience with the Shark Stratos MultiFlex Cordless Stick Vacuum. We’re sorry to hear that it hasn’t met your expectations, especially when it comes to handling pet hair.

      The HairPro DuoClean PowerFins are designed to minimize hair wrap, but for high-shedding breeds like German Shepherds, frequent emptying and cleaning of the brushroll and comb feature may help improve performance. If hair is getting caught before reaching the dustbin, we recommend checking for any blockages in the airflow path and ensuring the comb feature is free of buildup.

      We appreciate your patience and would love to assist further. Please reach out to our team at 1-855-427-5127, and we’d be happy to help troubleshoot or explore additional options.

      Kind regards,
      Shark Clean

    Bought for quick cleanup on porch, kitchen and stairs. Battery charge lasts 20 - 25 minutes on low, 10 min on high. Only charged to 90% after 10 charge cycles from 10% to 20% starting point. The brush on the crevice tool does not stay in place. Returned to Best Buy for a full refund after 14 days. Bought a similar corded model from Home Depot at half the price.
