I tried vaccum, steam mod, dry microfiber paper. Finally I prefer with damp mod (a microfiber - ZEP in Home depot) with warm water. Very simple and fast. Also clear stains. It only takes me about 1 hour to finish 5 rooms. I don't think damp mod would leave any water puddles on the hardwood floor. Since these are all pre-finished hardwood, it dries quite quick. I don't like any cleaning smell, so I don't use any cleaning liquid. If you have a little kid who spends most time on the floor, I don't think it is good to use lots of cleaning spray (chemical liquid).
