Great spot cleaner

I’ve had this for about 5 months and have used it numerous times for small pet stains and couldn’t be happier. It’s the perfect size and has a powerful motor that makes cleaning small stains easy. The included cleaner is a great addition that helps break the stain down. Cleaning is simply as you add a bit of water to the storage compartment and turn it on. Once that’s done the machine breaks down easy to let everything dry out.

LOVE LOVE LOVE

Love love love this. Hey SharkNinja CEO. Listen to this review. This is awesome for cleaning up those unfortunate spills but what this is absolutely kick *&$# for is stains. The stain remover ABSOLUTELY blows out of the park anything I have ever used before. With dogs and cats and kids, I have tried everything. I have never seen a stain MELT. Its nuts. Mr CEO, please alert me if you ever discontinue this as I will by all of the stain remover that goes with it. If you sold the stain remover on the grocery shelves, you couldn't keep it stocked! It is great to be able to suck up the stain but half the time it has already melted away with the spray. Well done!

Perfect for stubborn stains

[This review was collected as part of a promotion.] This is such a neat product. Firstly, I love the caddy and how it perfectly holds all pieces! Secondly, the guide is easy to follow and the cleaner is easy to use. Once fully charged the battery lasts a good amount of time. It is a bit noisy but not bad. Love that it’s cordless! Takes a few tries to get the hang of it but I am very happy!

Very effective, needs accessible replacement parts

I bought this is February and it was so incredibly useful. However, my yound dog chewed the plastic cover for the brushhead and I haven't been able to locate a replacement in stock since, so it's been gathering dust after just a few uses.

Stain cleaner

[This review was collected as part of a promotion.] The weight of the product is light which makes it easier to clean. The noise is not very loud which is good for my sensitive ears . I did have a very old stain that I used the product on. I cleaned half the stain to see how it compares . It did clean up pretty well but not completely gone. Will try to repeat the steps to see if I can get it completely gone .

Nice idea and decent suction, but ..

The tank is just too heavy for the handle section. I had to replace mine using the warranty because after 3 uses, I could only get the “install tank” error. It was clicked into place and I pushed as much as possible, but it couldn’t recognize that it was there. Upon getting the new one, I sense that the same thing will happen again. It’s like there’s only a teeny piece of plastic holding them together and the tank will fall off sometimes in use. Really wanted to love this product as I love my shark vacuum and plan on getting a purifier. But this one needs some updates and tweaks. The suction is good, not top tier, but this is a portable device so I would say it’s good for what it is for sure. I was impressed and happy the first couple uses. And now just scared the tank will break again

Hi Jenny, Thank you for taking the time to leave a review and sharing your experience. We’re really sorry to hear about your experience and can completely understand why this would make you feel concerned, especially after already needing a warranty replacement. This is certainly not the level of reliability we aim to deliver, and we understand how disappointing it is to feel unsure about the durability of a product you wanted to love. Thanks again for your feedback, and we hope the tank does not break again.

Not sturdy

Bought about a month ago for my new apartment, using as the instructions depict, and the lock broke very quickly making it difficult to keep together and so I’ve only been using for emergencies. While it was one functioning unit it was amazing, great suction. Easy to clean! Looking into the stain striker as it seems more durable

Battery life is bad

It does an okay job of what it's supposed to do: spot clean. And a lighter spot at that. It's nothing I couldn't have accomplished without some spot cleaning solution and a microfiber towel (though it would take a lot of towel and a lot more of aggressive rubbing). The batter life is so bad that I wouldn't be able to get heavy duty stains out. The last time I used this, it only lasted about 15 min or probably less.

Hi there, Thanks for sharing your experience with us. We’re glad to hear the StainForce helped with lighter spot cleaning, though we understand it didn’t deliver the level of performance you were hoping for with heavier stains. The battery run time is around 15 minutes, which is enough for most cleaning sessions. The unit is designed for spots, spills, and quick cleans. If you’re not getting the performance you need or have concerns about how your unit is operating, we’d be happy to take a closer look and help find the best solution. Please reach out to us through our support page so our team can assist you directly: https://support.sharkninja.com/contact-us Kind regards, Shark Home

That’s certainly not the experience we want you to have. We’d really like the chance to help make this right. Please give our Shark support team a call at 1-855-427-5127, Monday–Friday, 9 a.m.–9 p.m. ET | Saturday, 9 a.m.–6 p.m. ET.

Suction is weaker than expected from a Shark

The suction isn't very good.
