[This review was collected as part of a promotion.] We have been using this for a month now, and it's a real poor vacuuming cleaner. It hardly sucks the dust, and after vacuuming many rooms including many rugs, it only have a cuple of dust inside its cup. When i use it it always goes into this lock so i always have to out my feet on to losen it so it can vacuum. Also it only vaccum cleans when you push it forwards, not backwards!! This is not worth the money!

I bought this vacuum a month ago. I had a Shark before for about 7 years that I loved. However I was looking for a cordless model because dealing with the cord had become difficult for me. I also wanted to vacuum my kitchen floor more frequently and it was just too much trouble to get out the corded vacuum. This new model was on sale and the reviews looked good. And I could return it to Sam's Club easily if I didn't like it. As it turns out I LOVE this vacuum. It is fun to use and the Auto Empty System is wonderful. One reviewer said it was hard to remove the collection system container. Not so. If you remove the tape that is holding the container in place during shipping, the container removes effortlessly. You will not regret buying this well-priced Shark cordless vacuum with a collection system.

Its a good deal if you catch it on sale and not picky about performance like i am,i have a 8 year old shark that picks up atleast twice as good as this one,im carrying it back tomorrow for a refund and order a better quality unit ill be happy with very dissatisfied

Lightweight. Powerful suction. Easily comes apart to clean and maintain. Detection technology is impressive. Hair doesn't collect around roller. Battery life is less than I want (about 4 hours of moderate to heavy work). Dust canister lid almost always needs closing after auto emptying. This vacuum is my favorite thing that I bought this year. Car is second.

This only lasted in our home for 24 hours. In theory this is an amazing vacuum. It worked really well on our hardwood floors but when used on carpet or upholstery the issues started. It seems we got a defective one. I couldn't vacuum our couch or rugs without the vacuum flashing red lights at me and shutting off after 30-60 seconds of run time. I would have just exchanged it but the lady behind the CS counter said that this was one of several that she had seen returned in the last few days due to issues with them.

The theory of this product is OK. But the execution is awful. The automatic emptying feature is what is bad. It gets dirt in the part that closes and it needs cleaning out almost every time I have used it. And it's difficult to get it cleaned out so that it closes again.

Have yet to fully test but here is my impression so far: • The function of floor IQ is somehow lacking upon first use. I had to simply change the level to max to fully get use...but that could have been a first time hiccup due to lack of full charge as the battery died soon after initial use. • The flashing charge indicator is annoying on many levels and unintuitive. • The dock LACKS any real storage and the docking system or way in which it docks is cumbersome at best... problematic at worst as I can see it being an issue that could cause product damage in the future with one wrong docking. • The clip on the vacuum is for ..?!? What exactly?!? There is literally no storage beyond the one attachment spot on the dock which is put in a daft place and NONE on the vacuum itself! This is absolutely nonsensical!!! All in all, for the price point...I'm NOT impressed as a LONG time and DEVOTE follower and user of all Shark/Ninja products.

We have had a Dyson V7 for years and needed an economical replacement. Chose this one because of the auto empty feature on the base. I use this vacuum daily for limited jobs. I like the auto empty feature and the lighted brush roller head. There are two less-than-perfect details. 1) the auto-empty only works if you have the motor on the floor wand. If you use a handheld attachment, you have to swap back to the floor attachment before you can lodge in the base for the dirt canister to empty. 2) I vacuum a lot of crystal cat litter. The crystals don't transfer fully when emptying, and they will get hung in the back “gate”, requiring me to use my hand to clear the crystals and close the gate before using the vacuum again. My husband has said he wishes the power button was a trigger rather than a push button on the back of the motor requiring two hand operation - but I'm not as bothered by that. Suction is good.

So easy to use! Easy to clean and it is powerful! I love this vacuum.

We love it! Powerful, light and empties itself.
