Bought an older home and could not seem to get the kitchen and sunroom tiles clean. I used the scrub pads and after 2 days of using, the floors are finally spotless. Rest of the house is wood, the other pads worked great on wood floors. The sprayer is a big help, to monitor the amount of solution, that goes on the wood. I did buy another set of the smooth and rough pads. All pads wash easily in the washing machine.
