Before receiving this mop, I used a different brand of refillable mop.  I have laminate "hardwood" floors and the previous system would always leave them streaky with what seemed like a film behind.  I wasn't holding out high hopes for the Bona and figured it would be the same way.  I was totally wrong and impressed with the Bona!  I used laminate floor cleaner and their pads and had no streaking and my floors look brand new!  I'm so, so happy with this floor system and how wonderful my floors look!
