Use the product on a house full of carpet. We're old fashioned and don't like wooden floors. The greatest thing about it is that it is truly,, fully automatic. No more lugging heavy carpet cleaning machines or back-breaking scrubbing by hand. The solutions provide a pleasant smell to the house. It could stand to be a little quieter. Since it's automatic, fully, if you want to watch TV or listen to music, it's sort of hard. Could stand to have a warning that you're out of cleaning fluid; you have to remember to check the solution level from one cleaning to the next. As for stains, it cleans them, but tends to leave a water-spot-looking fringe around the edges. That's the main reason I reduced the rating. But, all-in-all, it's better than having to do it yourself.
