I have been using this on my hardwoods and my bathroom tile floor for almost a year. It works beautifully. My floors look wonderful and because it sucks up the water, it's better for my hardwoods than other mopping methods. It's also so much easier than mopping or hand-and-knees scrubbing. The only warning I have is that you have to be sure to allow the unit to get air after use. We had trouble with mold growing up in the base part where the brushes go and it was hard to get it clean, but when we be sure to store it in a way that air gets to that area, it's fine.
