    I'm so glad I bought this stick vacuum. It is very lightweight, has powerful suction, easy to maneuver, and has self-empty feature which is a huge plus. Goes easy on both carpet and floor. Best buy.

    Best cordless vacuum I’ve ever used

    This is an excellent vacuum! The suction is amazing, on hard wood or carpet or tile works great on all the floors in my house. The attachments come in handy for cleaning your car or even getting cobwebs from corners. We have 4 dogs 2 are Australia shepherds, so the shed is real! This is doing a great job of keeping up. Light weight, easy to assemble and use. I do wish the battery lasted longer but I’m able to get the job done!

    Nice Vacuum With a Poor Warranty

    After reading a ton of reviews and doing comparisons I settled on the Shark Detect Pro as a replacement for a Dyson that had power issues. This Shark started out as an absolute great replacement. The suction is a little weaker than the Dyson but still plenty powerful. It has 3 settings. The highest setting has proven to be enough for anything I tried to vacuum. Here are a few things that are good about this vacuum. 1. It changes suction power seamlessly when going from a throw rug to hardwood or linoleum flooring. 2. The power button isn't too close to the handle. Unlike the Dyson it won't turn on unexpectedly when you are handling it. 3. The base is one of the best features. When you are done cleaning just dock the vacuum on the base and it activates a 2nd vacuum that sucks all the dirt from the vacuum into a canister that can easily be emptied at a later date. 4. (Unlike the Dyson), this Shark does not blow a steady stream of hot air in your face if you are holding the vacuum over your head. Part of the reason I purchased this Shark is because they advertise it with a 5 year warranty. The base stopped working after only 5 or 6 months. It still charges the vacuum but it does not suck the dirt out when it is docked. Life is busy and I finally called Shark 2 months later. They said the base ONLY HAS A 90 DAY WARRANTY. Are you kidding? I did a video call with a technician. I showed them that the only way the base would remove the dirt from the vacuum is if I unplug it and plug it back in. Even then it doesn't always work. They offered to sell me a new base. I would have purchased a 2nd base if I thought it would last as long as the vacuum. I guess there is a reason they only give the base a 90 day warranty. If you don't care about the features of the auto-emptying base, I would still recommend the vacuum by itself. It does a great job. Too bad they couldn't put together a complete package. I also attached two pictures. I'm not sure why they designed it with a "pocket" in the top of the canister. Dirt collected in this little pocket and there is no way to get it out. It looks disgusting. When I did the video call with the support person they acknowledged that it was an issue.

    Hi potential buyers - This is amazing Vaccum cleaner, exceeds expectations! I was there where you are, sitting on the fence and researching which vaccum cleaner would be best, striking a balance between cost, features, low maintenance and greater peace of mind! When I dug deeper, found that market is filled with plethora of options. I compared it with many competing Brands/products like Dyson, LG, other products from Shark, Tineco, Eureka, Black&Decker and what not. Key winners: 1) Auto Empty Suction feature - It reads like a very simple or plain thing, but thats an amazing feaure. Key USP. No matter how dense the dust is collected, as soon as you hang the vaccum on the stand, within 2 seconds suction starts and runs for approx 6 seconds emptying it and transferring the content to the container. 2) Hair management: Its ZERO hair in the roller. Zero means Zero. I have been using it for a month and never had I found any strand of hair left on the floor or around the roller. Hats off to the Shark Team for designing this roller. 3) Large Container - kept my 4 weeks worth of vaccumed & accumulated dust and dirt, long hair and was easy to empty directly in my dustbin, without touching any of the dirt. 4) Product comes with 5 Yrs warranty. <Pls read the details in Specifications/BBY website.> And cherry on the cake is BestBuy's 2 year protection plan already covering it, so its great to be their Total Tech Protection member, no extra cost to pay for product protection. In fact, I had to return a Tineco beyond return window and then I bought this one and what an amazing decision that has been proven so far. Look at the pictures to help you make the decision like I did. Please make sure whichever you buy, should have Auto Empty Feature and you'll thank me! :)

    I absolutely love this vacuum!!! It has great suction, is light enough to do stairs with ease, and is powerful enough even in auto mode to do thoroughly do the job. You can hear the adjustment in corners and from wood to carpet. I vacuumed my entire downstairs, roughly 1300 sq feet, (including my furniture, rugs, and tile, and hardwood) and still had about half the battery life. The auto emptying base is AMAZING and I love the scent pod, it lets off a pleasant aroma, especially upon emptying. I think it’s worth every scent and would recommend it to anyone!!!

    As Good As It Once Was

    Honestly, I have always said that if I had my dream job, it would be to rate vacuums. I have two dogs and three cats and live in a two bedroom custom container. I like to vacuum and I do it multiple times a day because I am kind of a weirdo but all my weirdness aside. I was really excited to get this vacuum. The reason I was excited to get this vacuum was because I didn’t have to self empty the canister every time I vacuumed. I also was really excited to have a longer lasting battery. Unfortunately, I only got one of the two things that I was hoping for. The vacuum is really great, but it is now limiting me on how far I can go under furniture and also because the battery doesn’t last very long. The one thing that does work on the vacuum is a self emptying canister, which is truly one of the greatest things that they have invented. Call me lazy, that’s cool! Some things are about the convenience.

    Bought new rugs in Turkey. Needed a better vacuum cleaner. Tried this one because of the self empty stand. We have a cat so pet hair removal was key. Got it home charged the battery to full and started vacuuming. Battery didnt last longer than about 10 minutes. Completely ran out the battery and let it completely recharge. The battery lasts about 25 munutes now cleaning on full power. Great at pucking up cat hair. Easy clean, easy operation.

    The upgraded model is sleek and maneuvers easily under coffee tables and chairs. The added light to the upgraded model is a huge bonus which makes cleaning behind appliances and dimly lit areas much easier. The only downside is that it does seem to clog easier with larger bits such as dog toy remnants.

    Bought this vacuum for Christmas since our Tineco was breaking down. I was going back and forth between this and a Dyson and as I am sure the Dyson is great I am beyond excited with this Shark vacuum! More importantly my wife loves it! The suction is more than enough to pick up anything we had on the floor and the transfer from hard wood to area carpets is amazing! My other vacuums would get snagged or caught up and this one just goes right over! My wife also really likes the auto empty feature! That thing is like a space vacuum! If you are in the market for a vacuum definitely get one of these and they are on sale from time to time!

    I love Shark vacuum cleaners and this one is no different. The Shark Cordless Detect Pro Auto-Empty System with QuadClean Multi-Surface Brush roll is powerful handheld cordless vacuum cleaner with great suction and auto empty bin to help make your hectic life a bit less crazy. Now you don’t have to empty out the vacuum cleaner before you start vacuuming. This one does it all. The Shark Cordless Detect Pro Auto-Empty System automatically empties itself into the base station when you place back to charge, so you don’t have to deal with dirty bags or canisters. The canister holds up to 30 days of dust, dirt and debris that is collected by the vacuum cleaner. The canister is also equipped with an odor neutralizer to make sure that the area smells fresh and clean. The newly designed QuadClean Multi-surface brush roll is designed to clean all types of floors, including carpets, hardwood, and tiles. It also has a self-cleaning feature to help prevent hair wrap. I have been using this vacuum cleaner system for about 2 weeks now and I have yet to remove any hair from the rollers and I have three females in the house and my other vacuum cleaner roller needs to be cleaned every week. One of the main features of the Shark Cordless Detect Pro is that it features a dirt detection system. The Dirt detect senses the dirt that hides in your homes and automatically adjusts the power to meet your needs. The system can also detect when you are on carpet and on hardwood floors and adjust the roller speed and the suction based on the floortype. But don’t worry, you can also adjust the power manually as well. You have the option to choose between eco, DirtDetect, and Boost. The vacuum also has sensors built-in on the sides, so when it detects that you are cleaning an edge the vacuum automatically adjust the led lights and the suction to help suck up all that dust and dirt that hides in the corners. One of my main concerns with this vacuum cleaner was the suction. It’s much smaller and lighter compared to my other vacuum cleaners but to my surprise the size did not compromise on power. This vacuum cleaner offers the same powerful suction as a regular full sized cordless vacuum cleaner but just in a smaller package. The vacuum cleaner offers about 60-minute runtime on eco mode, but that time drops significantly when you are on Boost mode. I would say that you get about 30-to-40-minute run-time on boost mode. Pros: • Auto-empty system is convenient and saves time • QuadClean multi-surface brushroll • Powerful suction • HEPA filtration traps dust and allergens, making it a good choice for people with allergies Cons: • Feels a bit flimsy • Battery life could be better Overall, the Shark Cordless Detect Pro Auto-Empty System with QuadClean Multi-Surface Brushroll is a well-designed and a powerful cordless stick vacuum cleaner. It offers a number of features and convenience options and benefits that make it worth the investment.
