Product review (2 stars): Can clean but isn't well constructed or all that efficient.
The Wonder Wash can clean your clothes but except for the tub itself, it is very cheaply constructed and probably won't last long under constant use.  And don't buy that your kids will "love" to wash clothes this way, the Wonder Wash is too hard for younger children to use and what teenager is going to "love" to wash clothes?  In order to get clean clothes, you will have to drain the Wonder Wash from the top, tipping it quickly to get the dirty water out; otherwise, using the drain, the clothes actually filter the dirt out so the drain water comes out clean and the dirt is back in your clothes.  Plus, you still have to manually rinse everything so the water savings is very overstated!  As for the amount of detergent you use, the Wonder Wash is limited to how much it can wash at a time, two pairs of jeans fills it, and when you take into account how much you can wash in a normal machine, there is no great detergent savings unless you are foolish enough to follow the manufactures recommended amounts (remember, cleaning is a chemical process aided by physical agitation, if you have suds left in your wash, you had enough detergent (base) to loosen the dirt on the clothes and you don't need anymore detergent than that.  You might buy this if you need an non electric clothes washer, but for everyday use you need something else!
