    Shark vacuums are easy to maneuver and get in corners. Very light and easy to store, however they break. They lose suction. So buy them with a store warranty. This was my second one. Wish I could afford a Dyson.

    I love my vacuum. It was confusing at first, and then I finally got used to it, and now I love it! So easy to use and it’s compact because you could put the handle down. It’s perfect

    This Shark vacuum is an excellent vacuum. It does all its jobs very well. The cord makes sure you don't have to stop and let it recharge, and the size folds nicely for storage.

    Another great vacuum by Shark! This one covers all bases with excellent suction power, and the flexible hose makes it easy to store. I'd highly recommend, and it looks sharp too.

    With five dogs an excellent vacuum is a necessity. The dual rollers really deep clean carpet and with two speeds hardwood floors also shine.

    Good Vacuum!

    This was real easy to put together. No tools necessary. When assembled, I compared it to my shark rocket. There were a few differences such as the size of the motor assembly and the waste bin was bigger. At first, I did not think the unit was heavier than the rocket, but after doing the first floor, my shoulder and bicep were tired. So, I think the rocket is a bit lighter and easier to control. With all that said, I did like the dual brush heads, and it was great on hard wood floors. The brush heads moved so fast that the unit seemed to be self-propelled....maybe that is why my arm was sore...trying to control the unit and keep on pulling it back. It did a good job on throw rugs too, but almost too much suction and agitation that a couple of times the rug got sucked into the brush heads. I also tried it on the stairs..removed the pipe in between the motor head and the brush unit and connected each to each other...it was light weight enough and performed pretty darn good. When done, I emptied the canister, which was easy enough, and noticed the foam filter that says it should be washed once a month. The dust bin was also quite dirty on the outside too, so had to wipe it off before putting it back. I am not too thrilled with the foam filter and it requires maintenance, but I guess it is better than having to buy one. When I was putting the unit away, I noticed that the hook that the electrical cord wraps on was on the center bend area, and was much lower than the one on the rocket. Because it was so low, one had to bend over to wrap the cord. Not good for the back, though I can understand the placement if one us going to store the vacuum in the bent position. It is a very nice vacuum and it looks sharp in black and gold...two of my favorite colors. I would love to see some of the improvements put on the rocket.
