So we must be very dirty because my Fuller String mop head needed replacing in only three months time! I had to go with a commercial looped string mop which really works well and is lasting longer. It is large and heavy, and requires a professional mop wringer, but the weight of the mop does much of the cleaning for you. I also tried a stronger cleaner, LA's Totally Awesome concentrated cleaner(ammonia and bleach free) from the Dollar Tree. This put a shine back on the painted concrete floors and got up a lot of my daughter's glue and paint. I used it on the laminate floors and got good results as well. About a four of a cup of it in a bucket with hot water is all I needed for heavy floor cleaning.
