Vacuum was easy to assemble. Love all the features this Shark has to offer. The handle when detach from the vacuum to use an attachment has a light. Very powerful vacuum I caution you to not, I repeat, not to run over the cord. This vacuum will tear it up and eat it. No joke how powerful this vacuum is. No need to do arm day at the gym because this vacuum pulls but that tells me it is doing it's job. The cord is 30' long which is 5' longer than my other Shark. This is my 2nd Shark and I love them. I donated my other to our church since I have wood floor almost everywhere in this house I decide to buy this vacuum. I don't regret it one bit and I had this for about 3 weeks. I call it the ironman vacuum.

(What's this)
This is a very versatile vacuum. It has a lot of suction power. It is so easy to use. It swivels well and is low profile so fits under more furniture than my older vacuum. It self propels forward on carpet. I am always surprised at the amount of dirt and how quickly the dust canister fills up so it really deep cleans the carpet. It has settings for bare floor, low pile and high pile carpet. I have wood floors that get very dusty quickly. The light works well to be sure I'm cleaning the entire floor. I love the soft brush roll for hard floors. It picks up all the dust. There is also edge cleaners so you can get in all the corners. You can detach the canister for above the floor cleaning. The hose and cord are sufficient lengths. The crevice attachment has a brush, which I have used a lot to clean my baseboard moldings. It is very easy to empty the dust canister. I dreaded vacuuming with my other vacuum (different brand). This vacuum is so easy to use, it makes cleaning the house a breeze.

(What's this)
I have had this several weeks now and this lives up to the Shark name. It has powerful suction. And is very light in the hand for being 15lbs. The cord is 30 feet in length, so I can get most of the house done with just using two outlets. It is easy to clean too since the container can be just tossed over a trash can. The swivel head is a nice touch. I have never had that before. It moves along carpet, tile or a hardwood floor with ease. And with the height of the head, you can get under the inner few inches of a couch that is 3-4 inches tall. And when you use it in the flat mode, you can go all the way under a bed (anything over 4 inches) no sweat -- including lights! It comes with a crevice tool, a brushing tool for pets and couches, and a dog grooming tool (standard brush). It really does lift the carpet so much that you know it got cleaned! This has a 7 year warranty. I really like it.

This is an absolute awesome vacuum. When I received my new powered lift away vacuum I had just gotten done vacuuming the main floor of my house. Just for the heck of it I re vacuumed the same area I had just finished with the Shark powered lift away and it was almost embarrassing. I can't believe the amount of dirt I got after just vacuuming. It comes with some very innovative attachments such as a clevis tool with a brush that slides up to the end and locks in place for dusting to a vacuum powered small brush to use on stairs or furniture. I can't say enough about the versatility and power of this machine and priced about half of the leading competitor. The innovative design allows you to easily take the brush head and the bag-less canister apart for cleaning. I am impressed.

This vacuum cleaner is like the Cadillac of vacumn cleaners! The box arrived in very good condition, the graphics on the carton were impressive. It was very well packaged. The I structions were easy to follow and I had it together and ready to go in 10 minutes. I vacumned my basement first with a Dyson battery powered upright, then I went at it with the shark, it was easy to push almost like it was powered to go in the forward direction but pulling it backwards was easy too. Getting used to the swivel action took about 2 minutes. It was easy to get underneath the pool table and around furniture. I used each attachment and they worked great. I read that some people thought the vacumn was a bit noisy but I did not think so. I was very suprized by how much came out of the carpet after the use of the other brand machine, very pleased with the Shark DuoClean vacumn.

(What's this)
The bottom line – it’s an excellent vacuum cleaner, the vacuum has strong suction power, a motorized floor nozzle, detachable canister, is easy to maneuver and easy to empty the canister. All of the vacuum components easily detach and re-attach – snapping into position (except the accessories which are slip fit). The motorized cleaning brushes propell the floor nozzle forward only and not backwards – until you get used to the weight it feels heavy pulling the vacuum backwards (the vacuum weights 16 1/2 pounds – the 23 pounds shown in the specifications is the shipping weight). The floor nozzle easily transitions from hard floors to carpet, a 3 surface selection switch on the handle controls the speed of the brushes – the powered brushes cannot be turned off for use on hard floors – but since the front of the floor nozzle is supported by two small wheels behind the front brush, control of the floor nozzle is not a problem. Detaching the canister allows vacuuming under furniture (requires about 4 inches of clearance – see photo – the detached canister can be used as a portable hand carried canister vacuum (weight is 7 3/4 pounds) or placed on the floor. Two minor issues: 1) it does not have an edge cleaning feature – the bottom of the floor nozzle appears to have channels to the side, but it did not provide adequate suction when used on carpets; 2) cannot clean into corners using just the floor nozzle, the nozzle is 12" wide, but the brushes are only 9 1/2" wide - see photo – back to using the crevice tool.

Very impressed with this vacuum! Background: I had a Dyson ball that was about 10 years old and was starting to get holes in the hose and wouldn't sit up right anymore. Features I LOVE: -lift away canister, light, easy to maneuver, carry up the stars or use under furniture -when in lift away mode you can basically get the vacuum so flat it is about 2.5 inches tall so you can get under the bed or couch -New roller thing in the front sucks up big pieces AND those big pieces go in their own special section in the canister -Powered brush tool DEMOLISHES Dyson when vacuuming my couch (I have pets with short and medium length hair) -LED lights on the HOSE are AMAZING. Kind of terrifying to see just how much hair I had been missing from the Dyson. -Filtering the smells is better than Dyson. Still not perfect, however. We have stinkbugs in the country and when you suck them up, you can smell them, but Shark is better than Dyson in this regard. -The power and mode buttons are on the handle which is so nice. -High quality roller blade wheels for maneuverability. Definitely an upgrade over Dyson's hard plastic wheels. There are so many features that Shark added to make the vacuuming experience convenient and pleasurable. Highly recommend this vacuum.

The Best!
Customer review from sharkninja.com logo
I absolutely love this vacuum! I clean houses for a living and have used this vacuum for the last 5 years... my only complaint is that when it was time for me to buy a new one, I noticed that they shortened the cord on the newer models...having a super long cord was one of my favorite things about this vacuum... Please make the cords long again so by the time I have to buy a new one again, the cord will be back to the way it was!

Great general vacuum
Customer review from sharkninja.com logo
This is my 3rd Shark. I had 2 of the Rotator models. The 1st one I didn't realize I could call and they would replace broken parts under warranty. So the second one, when the same part broke, which was right at the top of the wand, was letting air out, no suction.. i simply called and they didn't even charge me shipment and replaced my hose for free. Next time it broke they sent a new hose, free filter and duct cup because the clips broke off on it. Im brutal on my vacuum, I have 5 dogs, 3 are pure Siberia huskies so I have lots and lots of hair. So finally the other day it would only run 20mins then would overheat.. had enough and broke down and bought a new shark. I believe with anything, you get good ones and bad ones some slip past quality control. But they DO stand by their warranty, I guess you just have to know how to speak to them, but I've never had an issue. I highly recommend.
