A micro washing machine for daily runners

Problem: Do you practice running frequently? Do you have kids that play football regularly or any other sport? If so you know that you will have dirty smelly clothes daily that need washing. But you're not going to spin that big washing, use a lot of electricity and water daily because of one t-shirt and one short are you? Solution: A mini washing machine. There are some out there in the market, but none are practical nor nice looking. I would like to design a very simple washing machine that: - is as small as possible: needs to accomodate for: one t-shirt, one short, one pair of socks, one underwear, that's it. Note that the clothes would be running clothes, so very light - Runs on batteries - Uses very little water, 500ml max - Is very quick: 5 minutes max - Dries the clothes: It does the spinning to dry the clothes - Dead simple to use: One button to push, no more. Digital counter show the number of seconds remaining - Sexy: See example image of a fridge that is sexy in my book THIS IS A COMPETITION: Please provide proposals and I will pick a winner to go and design the product. I want you to use your expertise and free thinking to help me make this success.
