The Drumi is a foot-powered washing machine, so don't expect it to hold a huge amount of clothing. Still, the company says the Drumi will handle about five pounds, or 6 or 7 "personal items." that means, shirts, underwear, socks, but a pair of jeans can be run as a single load. Sorry, towels and sheets are a bit too big.
How much time, energy, and water are involved here? Figure about two and two-thirds gallons of water for a wash and rinse. Your foot will keep busy with applicable breaks. Two minutes to wash, two to rinse, and a minute to spin out the water – that's got to be an improvement over those "miracle" washers where the clothes come out soaking. And no special soap is required, powdered, liquid, or eco-friendly laundry soap are said to work well in the machine.
Want one of your very own? Be prepared to spend a little over $100 – but you'll wait a while to get one. While the company is taking pre-orders now, it'll be summer of 2016 before you should expect delivery. Meanwhile, watch the video – no soap opera here.
