I just joined this forum to ask if anyone can help me. We bought the Shark Steam Mop a few weeks ago to clean our kitchen tile. We have two shelties and they use pee paper in the kitchen. They don't always hit the paper and it goes on the tile and in the grout. I have always taken the paper up and mopped when this happens. I had hoped the steam mop would be able to clean the urine off the tile and grout. We have used it several times now and the tile still smells just like it has not been cleaned. Is the steam cleaning not able to sanitize and clean dog urine from tile? If anyone has any ideas please let me know. I'm thinking about returning the mop. I would appreciate any help. Thank you.
