I bought a Hoover Floormate to clean my sealed hardwood and tile and am now returning it throughly disappointed. It worked very well and I was thrilled with how clean it got my floors - for about the first half-hour I used it, then it quit spraying the cleaning solution. I have a very large house with lots of sealed hardwood and tile and need something that will clean ground in grime off the floors. Years ago, my mother had a carpet/floor scrubber that had 2 revolving scrub pads and could also be used to buff floors. I think it was a Sunbeam. Does anyone know of something similar that you would reccommend?
