How many square feet will it clean with one pad
do you have to keep changing pads
It depends on the state of your floors. The first time we cleaned our hard wood, we didn't change in the middle of mopping, we just mopped twice. We have about 400 sq ft of laminate and 100 sq ft of tile. After mopping last week, I mopped all of the laminate with 1 pad and never changed it.
