[This review was collected as part of a promotion.] I love how compact this machine is. It stores easily in the cupboard under the sink in the bathroom, so it's on hand upstairs where we have carpet. It's a powerful little machine, and has so far performed very well. It has an unusual two-tank system - one for the hot water and cleaning solution, and the other for the oxy stain treatment, and this seems to work really well. The machine has three really great features that make this stand out from other cleaners I've tried: First is the pet mess attachment. This has a built in filter and a container that quickly unscrews - when you're cleaning particularly obnoxious messes, this will gather the "chunks" locally at the head, rather than drawing the mess through the entire machine. This makes it much easier to clean up semi-solid messes. Secondly, the tool heads have the slots through which they draw the liquid. On other cleaners I've used, these are solid pieces, making it really difficult to clean properly after use. On the Shark machine, the front plate unclips, allowing you to easily clean inside. I love this feature! Finally, again on the subject of cleaning the machine itself, there's a plastic cap that fits over the end of the hose, and is used to redirect water straight back through the hose to flush it out. Simple but brilliant. Overall, I can definitely recommend this cleaner. If I had to find fault with it, the hose is supposed to wrap around the base of the machine, clipping the tool handle to the side. Mine barely reaches to clip into place, maybe because it's still relatively new. A minor point, because as I mentioned, it's compact and stores easily in a cupboard.

Product arrived with solution to use and attachments. The machine itself is very well made and took up stains like a PRO!

So far I love the new Shark Stain Striker. It works great! I have four cats and this machine has been cleaning up all of their messes.  The Shark Stain Striker is easy to use and clean. For years I used Bissel and over the past two years they break before they make a year. I own Shark vacuums for many years now and love them. I’m hoping the Stain Striker is as good.

[This review was collected as part of a promotion.] My son spilled "something" on his carpet and never told me about it. By the time I discovered the stain, it was set. I tried numerous stain and spot removers but none of them worked. I used the Shark StainStriker on the same large stain, and after two applications, the stain was completely gone!! I couldn't be any more happy with this device. I then used it on a set stain on the backseat floor of my car, (seeing a pattern here) and it also removed the stain after only one application. The StainStriker works as advertised, only con to this device is that it slightly "leaks" around the hose seal and your hands get wet, other than that, I highly recommend this product.

[This review was collected as part of a promotion.] I live in an apartment, so having guest come in with outside shoes makes the carpet look weird after a while. I can’t wait to use this when i deep clean this weekend. I love that it came with the solution

I had originally purchased my shark vacuum at the beginning of this year. I had only used it a handful of times. It works extremely well! I was very pleased with its performance however I do believe their design is flawed. After only using it a few months my hose broke. The hose isn't quite long enough to wrap around and hook in the intended spot. It causes too much stress because you have to stretch it. Shark was very easy to work with to replace it though. I don't plan on wrapping the new hose around the machine like the other one to prevent the hose from breaking again.

I bought this to help remove stubborn stains from my carpet but found no difference in the stains  help I most need help to remove. It ok for like coffee or pet stains and such, but the unit is heavy, and too much trouble and expense for the stain removing power it offers.

I’ve been looking for a small spot cleaners and since I have so many Shark products I knew this Shark Stain Striker was a perfect choice I’m very happy with my new Shark product

5 days after having brand new, cream colored carpet installed my husband sliced his foot open. He was able to get off the carpet and into the kitchen before covering the floor with blood. There were only a few drops of blood on the carpet until my blind dog, running in to see what was going on, stepped in the blood on the kitchen floor, tracking it all over my new carpet. We had purchased the strainstriker portable, as well as the Carpet xpert with stainstriker. The portable got all the blood up with no problem at all. Shark user for life!
