I think you helped to hook me on the microfibers and I do adore them - but I agree you need to have an in-home washer for it to work out well. I do occasionally use paper towels but not at the rate we used to.
I tried the steam cleaner on the bathroom upstairs after we used our regular floor washing thing. It did bring up a little dirt but not much - not like when you use it on a carpet you think is clean. So it was fun to try, but at least in our house it didn't seem to be a bit impact. Maybe that bathroom - with only two of us in the house - just doesn't get that dirty. We take off our shoes at the main house door so the only things touching the floor in there are our bare feet or our socks.
