My motivation for deciding to try these was to find something between monthly crawl-on-the-floor-on-your-hands-and-knees floor washing, and daily sweeping.

Here's what I found:
1. You have to sweep the floor before you use these. It will not pick up all the loose stuff.
2. One wet cloth will only clean about fifty square feet of floor before it's dry.
3. Flipping the swivel head over to be able to use the little scrubby side is such a pain that it's not really worth it.
4. You WILL still have to get down there and clean the corners every so often, which is why I'll have to stick to the monthly thing.
I use these once a week.
I'm cheap, so to overcome the fact that the cloth will only clean a fraction of my floor space, I fill the laundry sink with about a quarter inch of water and dip the end of the Swiffer® in there when it dries out.
I just shake it a little to remove the excess water and off I go.
I clean the heavy traffic areas (around the refrigerator and kitchen table) first so as to utilize the cleaning solution in the cloth.
This review is my personal opinion.
The Swiffer company is (obviously) not compensating me but if you need more information about this product, they answer many questions, especially on the safety of their products, on their web site.
