Customer Reviews for Shark - StainForce Dual-Activated Refill Cartridge 2pk

Verified Purchase:Yes
The cleaner itself is good but to cover messes larger than 2x2 goes through the bottle quickly
No, I would not recommend this to a friend.

Hi Brian,
Thank you for sharing your feedback. It’s great to hear that the cleaner performs well, but we can appreciate how frustrating it can be when tackling larger messes and finding that the solution tank empties more quickly than expected.
The amount of cleaning solution used can vary depending on the size of the area being cleaned, the level of soiling, and the cleaning mode being used. Feedback like yours is valuable because it helps us better understand how the product performs in real-world cleaning situations and what matters most to our customers.
We appreciate you taking the time to share your experience.
Kind Regards,
Sharkninja

[This review was collected as part of a promotion.] Great stain remover :) Some of the stains are gone before you even have to scrub or use the Stain Force.
I would recommend this to a friend!

I bought this hoping it would help eliminate some pet odors. it DID!
I tried too many other products to admit on other spots (same issue). this worked beautifully.

I love this thing! It's so easy to use, clean and overall a GREAT tool to have. My wife and I have a housefull of cats and this thing....it's AWESOME!! Little messes here and there..DONE! They ONLY drawback is it doesn't hold a charge for very long, but that's okay. I probably am just using it too much!
I would recommend this to a friend!
