If you want to go green, this is about as green as it gets. When the washer is assembled it looks a little like a plunger. You fill a container with 4-5 inches of water, add your detergent, and start to wash. Wash your clothes using a plunging motion for about 3 minutes per item. That's it!
This is a video I found on You Tube that demonstrates how the washer works. It's very simple and of course the kids think it's fun. The only problem we have is that we don't have a wringer right now to wring the water out of the clothes. If we intend to use this on a regular basis then that is something we will have to invest in soon.
We did test it and it worked really well. We were actually shocked at how much dirt it got out of our sheets. We tried it out on our queen size bed sheets, one fitted, one flat, and four pillow cases. By the time we were done the water had gone from clear to gray. We were amazed at how well it worked.
I would highly recommend this if you would like to have something to use in case of emergency or to keep at a retreat. This would also be great for extended camping trips. I know I am personally tired of having to use a laundromat and it will probably be a while before we can use our washer and dryer so this may be a good option for a while.
