The listing, Rapid Washer has ended.
The rapid washer or the breathable mobile washer as it's also called is good for washing your clothes when the power goes out, when you're camping, when you're low on funds and when you don't have a washer/dryer.
The good news, it comes apart and together really easy.
I've used it but don't need it anymore, no rust at all since it is plastic, and it gets your clothes clean just as good as a regular washer, you just power it instead of a machine. The good thing is you actually see How clean your clothes are really getting.
All you do is use a bucket, water, detergent, allow the clothes to soak in the water for a bit, then use this to wash them and drain. To rinse you also use this.
