I received the Shark Stain Force with caddy and reusable spray bottle with cleaner. The reusable spray head does not work at all. I have went through the trouble shooting and nothing. Trying to turn in warranty and it keeps saying model not found. From other reviews with same issue I am thinking Shark may want to figure out why this keeps happening.

Does not work

Brand new and the spray bottle does not spray. I followed the exact directions and still nothing. This unit is worthless without the cleaning solution. Very disappointed.
No, I would not recommend this to a friend.

Doesn’t work

We recently bought this for small spot stains. The stainforce spray bottle doesn’t work at all, no matter how many times we try it. Without the spray, the handheld cleaner is essentially useless.
No, I would not recommend this to a friend.
