I am amazed at how this works; I have white dining chairs, and with my kids, the chairs already had stains, but with this magical cleaner, they are back to pure white. Thank you, Shark, for your amazing products; there is no need to sweat to remove stains, as it works super easily and without any hassle.
I bought this based on a review I watched. The one I received has no hose cleaning tool, how gross that would be. Flushing it with water manually is a mess, forget it. And the hose end no longer swivels. Typical Shark, they cheap out and screw you, why do I ever buy from them? Returned.
No, I would not recommend this to a friend.

Hi there,
Thank you for your review.
We're sorry to hear that the product did not meet your expectations. We understand how disappointing it must have been to find that the hose cleaning tool was not included as expected and to experience issues with the hose end no longer swivelling properly. We value your feedback and will ensure that your comments regarding the cleaning design, product features, and overall experience are shared with the relevant department for review and future product development.
I have been using this portable StainStriker every where. I have a big carpet steamer for whole house cleaning but this one is perfect for quick messes from my cats. It is always ready to go. I make a stain in the downstairs carpet and came up and grabbed my portable Shark. So easy! Could not have ever got my big machine down and up my stairs. Love this thing!
I've owned this for less than two years. It's started leaking on the floor when not in use. I've checked to make sure everything is connected properly. Not sure how it's leaking. Going to have to throw it out.

Hi there,
Thank you for taking the time to leave a review.
We're really upset to hear that your unit has started leaking after less than two years of ownership, especially after you've already checked that everything is connected properly. This is not the experience we want you to have. We'd like to help investigate the cause of the leak and see what options may be available.

We bought this because of a sick pup with bladder stones. Accidents have been happening frequently until surgery is had. This works great and easy to clean in between. Great buy!
I use this one time and it worked great. I tried all the troubleshooting suggestions and still would not work the second time I tried using it. For me, anyway, it's a piece of junk unless you only want to use it one time.
