Query: LOVE this product

I just recently purchased this product and I am very happy with the results I have received. I have a light colored ceramic tile in my home and therefore keeping it clean is a chore. This product is very easy to use and gets the job done. My only dislike, which is farily minor and why I rated the item a "4" instead of a "5", is that I have noted water spots on the tile- not all the cleaned tile but only in certain areas. Has anyone else had this problem and is there a solution?? Otherwise I love it- there is nothing better.
