Product review (5 stars): Love love love it! Clothes are cleaner than ever before, and NO SOAP!
UPDATE A YEAR LATER:
We are still totally happy with the pureWash. For really soiled items, like the napkins and placemats we use daily, I sometimes do a pre-wash with a tiny bit of soap, but otherwise never use any at all! If we use stain stick on items like shirt collars, I might do a pre-wash as well, but without adding soap, just to get a little more wash time.

One time I noticed the clothes were not clean when I removed them from the washer, and then realized someone had unplugged the pureWash. So you can definitely tell the difference. Our washer has an "eco-cold" water setting that uses no hot water at all. Apparently, most washers' "cold" setting uses a little hot water to help dissolve the detergent. Anyway, the colder the water, the better it works. We couldn't be happier with it. I still don't understand why utility companies and appliance salespeople aren't pushing this item more forcefully.

ORIGINAL REVIEW:
We recently had to replace our washing machine, and our local store had brochures about this unit. I'm surprised they didn't even try to sell it to me - I was just intrigued by the brochure and asked them about it. They charged about 25% less than the lowest cost I've seen online. Even though I used to wash mostly with cold water, I wanted it anyway because of its other features. First, it's just a cool gadget. Second, did I say this before? NO SOAP! Third, I no longer need to use hot water at all, even on towels and cloth napkins and cleaning rags like I used to. If you do use hot water, this should be what they call a no-brainer purchase for you.

I predict this will be the next big thing in the home appliance industry, as long as the soap industry doesn't find a way to scuttle it. Between this and our new washer, which uses much less water than our old first-generation Neptune front loader, our water and electricity bills are definitely going to go down this year. Plus our clothes look cleaner than ever before. Whites actually look whiter, just like the old detergent ads used to say.

This item is definitely a winner!
