It uses a HEPA filter and Complete Seal Technology to trap 99.9 percent of dust as well as pollen and other allergens so you can breathe easier. A convenient lift-away function detaches the canister from the main unit so you can reach the tops of doorways and other high-up spots. This Navigator Lift Away vacuum includes a selection of attachments to deploy, such as a wide upholstery tool for removing pet hair from furniture, a dusting brush and one for tight crevices, such as beneath sofa cushions. This Shark Navigator Lift Away professional vacuum is lightweight and easy to maneuver under and around furniture for a more complete cleaning.

    Works great with 5 cats!

    I previously owned a Hoover canister with beater bar floor attachment. The day before I bought this Shark model, I used the Hoover with two new filters and a new bag in it. Then I used the Shark on the same carpet. I could not believe how much stuff it pulled up the first time I used it. I have used it a couple more times since and my carpets actually look different. They look more puffed up and newer as opposed to be squashed and matted down. Today I used it upstairs on a maybe 6 by 8 foot carpet section in my bedroom, a 2 by 8 carpet runner, and one pass around my spare bedroom bed on the wall to wall carpet. I did not see any globs of cat hair when I looked at the carpets before using the Shark. I took the attached 2 photos of what was in the vacuum after I finished vacuuming only those rugs. WOW! I love this Shark! I have 5 cats. 4 of which are long haired. I do have to check the beater bar and clean the roller from time to time. Mostly because some of my carpets are OLD and strings get wrapped around the roller. As long as you so some minor maintenance on the rollers on the beater- you will be fine. The only thing I wished this model had was a retractable cord. Other than that it is easy to use, easy to carry up stairs. Easy to lift away the vacuum to take off the floor roller. Canister is very easy to empty too. I take it outside to my garbage can and click one button and it dumps the dirt. Using wet diaper wipes to wipe out the canister takes care of the powdered residue. The powder is clearly cat litter tracked on the carpet from the kitty paws.

    We bought this sweeper a couple wks ago and love it-we could not believe the dirt this picked up. we have a dog-so there was lots and lots of dog hair-we did not even know was on the carpet. We would recommend this sweeper to anyone needing a "good" sweeper.

    I thought I had a clean house!

    I bought this vacuum for the no loss of suction feature. I have been using a pretty expensive vacuum to clean my floors and thought it was doing a good job. At least, the canister always had a little tornado shaped dirt pile in it that lead me believe so. I did a before and after vacuum job with my old vac and the Shark and then compared the dirt piles. OH MY GOSH i was disgusted. I thought I kept a clean house but look at what I had been missing with my old vacuum this whole time! The piles on the left are from my old vacuum and the right is what the Shark picked up right after it. There is a quarter in the middle for scale. I have used my Shark about 7 times now and each time the dirt pile has been significantly smaller. The suction stays strong the whole time. Now that it has caught up on what my old vac was missing, I am just doing regular vacuuming. Another great thing about this vacuum is that my carpet fibers stand up again like new. No more matted down carpet. I love that I can turn the roller brush off and go straight to my hard floors. I didn't know it did that so it was a nice surprise. Awesome vacuum! And Walmart had the best price and shipping fee that I could find. You won't be sorry.
    SHARK vac compared to my old vac.


    As a cleaning fanatic, I have owned and used every vacuum on the market. In the 10 years that I have been in my current home I have used Miele, Riccar, Rainbow,Electrolux (canister w/powerhead, Upright, Kirby G3, Hoover. I vacuum everyday and decided to try the Navigator after reading all the reviews. I am shocked to see what this machine is pulling out of my carpets, to the point I am now considering not installing the central vac system that is in my garage waiting to be installed. I have never even considered a Dyson as they weigh a ton and are bulky, not to mention way overpriced for what you get. I guess you can say I am very impressed with this vacuum and if I do end up installing the central vac, this Navigator will be my daily vac and the central for my real cleaning days. Go for won't be disappointed.
    First vacuum with Navigator...vacuumed the day before

    The best vacuum ever!!!

    I never had a feeling one way or the other about a vacuum cleaner. I simply picked what looked to be the best choice in the store and went with whatever "cleaning" I received. I clearly was wrong about making such an important choice. Well once again I needed a vacuum and bought what I thought was a good "random" choice from the store. I got home and after unpacking my 8 year old pointed out that the front wheel was missing. I returned the vacuum and decided to put some work in. I researched many brands and found the Shark Navigator Lift. At first I was very hesitant about spending so much for a vacuum, but after reading many positive reviews I decided to try it out and I am so glad I did. My youngest has severe allergies and I'm betting that living with that pile of fuzz I vacuumed out of the carpet had something to do with her constant sneezing fits. I'm a tightwad in many ways, but this vacuum is worth every penny and more to really be in a clean home. And btw the way I just moved in 2 weeks ago and this pile of fuzz was picked up in the first vacuum session of a living room dining room combo, so the space wasn't that large.
    The whole cup was stuffed with fuzz!

    Great Vacuum, but no power attachment

    This model is advertised that it comes with the pet hair power brush, it does not. They sent the same one saying it would have the attachment and did not so I kindly asked them to remove the photo of the motor brush and from the description over a week ago and they have not. If the brush is something you want for your stairs or small rugs, don't buy this model. We had to return 2 vacuums and find a model that does have it. However I did use this vacuum after using my sister's dyson and it picked up SO much. I was grossed out how much the dyson left behind. Great vacuum.

    Amazing suction.

    Holy crud! I cannot believe the crud that was in my carpet. I have had an Oreck for 20 years and have used hepa filtration bags. I've known for a while that I needed a new vacuum, but I couldn't afford a new Oreck. I thought I'd buy this as a "tide-me-over" until I was able to afford a newer model of the old standard. I don't think I'll need an expensive model after all. I have three dogs. All of them are horrendous shedders. They've destroyed the grass in the yard in patches by rolling in it and digging huge holes. Needless to say, they bring in a lot of dirt and dust. I've tried to keep up with it, but it's nearly impossible. I was thinking of replacing the carpets with hard flooring because they're in such terrible shape. However, after using this vacuum twice (in one day), the living room carpet has gotten a new lease on life. It is no longer matted down and "old" looking. The only problem I have with the vacuum is the static build up in the carpet is CONSTANTLY discharged through the plastic of the handle (and body) of the machine. It can be painful. I checked with the company and can get it replaced. However, doing an online search, I've since discovered this is an issue with modern plastic vacuums and getting a new on will not solve the problem. There is no issue with static shock when using it on hard surface floors, so it is definitely NOT and electrical issue, which I feared. It has been easily remedied by wearing rubber gloves and rubber soled shoes. Yes, I look ridiculous vacuuming the carpets wearing rubber gloves, but it sure beats getting zapped every ten seconds. A few other suggestions were to (1) spray the carpets lightly with water a few minutes before vacuuming to increase the moisture/humidity in the air (2) putting lotion on your hands before using the vacuum (3) spray the vacuum with an anti-static spray. Since I'm too lazy to do any of those, rubber gloves during the winter it is. I might get some latex spray and spray the handle to give it a rubberized coating and avoid the gloves. However, I don't want to void the warranty by doing that. (The photos are the reasons I need a really strong vacuum. The white dog has crossed the Rainbow Bridge.)

    Good cleaner, good job

    The cord is very long winded and comfortable, well vacuuming. And cleans carpet brush

    Best vacuum cleaner ever!!

    This is truly the BEST vacuum cleaner I've ever owned! I've always owned very expensive bulky vacuum cleaners and really thought they were great. One day, it wasn't working properly so I did my research and decided to finally go bagless. I'm so happy I chose this particular brand and model. I was shocked the first time I used it because I thought my carpet was pretty clean. It wasn't!! There was even carpet powder from previous cleaning days! I was so grossed out! I have 2 cats and couldn't believe all the cat hair it picked up! Keep in mind, I had just vacuumed a couple of days before! The lift away feature is so easy to use! I did my stairs in record time! It also works great on bare floors. I have hardwood, tile and marble floors and it does a great job as a sweeper. I promise you won't regret just going for it and purchasing this vacuum cleaner. If you're anything like me, you're going to absolutely love it and vacuum way more than you ever have in you life because it's so simple to use!


    I previously had been using a Kirby, I hated all the attachments and honestly it was so big and heavy just didn't like anything about it. I researched the Dyson and this Shark. The shark is obviously better price. I read the reviews on this Shark navigator lift-away, they all were really good. between the reviews and they $ I purchased it. I had vacuumed with my Kirby that morning and in the afternoon when my shark showed up I had to try it immediately. I was SHOCKED at the amount of stuff that was left behind by my other vacuum that the shark picked up. I can't believe how dirty my carpet still was and how much it picked up. My husband even stated that our house even "smelled cleaner" after I vacuum with the shark! I have two little boys and we live in the country so our house easily gets dirty! Its super easy to put together, also easy to use on carpet and hard floors. Love that there is no bags, and that I can detach the hose easily to use. I would recommend this to anyone.
