The Hoover Powerdash Hard Floor cleaner made an immediate impact. I have been very leary of using a water floor cleaner, worried about too much water hurting my floors. I also thought that machines would not get all the water from the floor, and I would need to go over it many times. I am happy to report I read the directions for cleaning, and the floors look amazing. The machine is light, easy to fill with water and cleaner. The dirty water tank of course was disgusting. We have a dog, and the floors do not show dirt (well not too much) the PowerDash has scrub brushed that really got in the grooves of the floor. I did the heavily used portions of the floor first, and then the areas that are not traveled on. The floors look like they did when they were installed. The floors are not slick, the solution did not leave any residue. Very happy with cleaner
