I just got one of those hand-crank washing machines and a low-energy spin dryer. Next month I'll be moving into a place where these will be my only nearby method of doing laundry, and after using testing them out last night I'm actually kind of looking forward to that. (I did a blog post on my laundry nerdery
here.)
In case anyone else might be interested in these sorts of machines, here's a quick review:
Wonder WashReason I bought this model: It has a greater capacity than most other hand-crank washers on the market (5.5 lbs of clothes) and has gotten stellar product reviews online, even from people who don't usually hand wash anything.
Pros: It's cheap ($43), uses no electricity, takes less water and detergent than a standard washer would for the same size load, is easy to use, and takes only 2.5 minutes to run a load (probably comes out to around 10 minutes once you include loading, rinsing, draining, and added clutz time for a new user). The cranking also isn't as effort-intensive as it seems at first, and washing clothes this way consistently should make them last longer.
Cons: It has a much smaller capacity than a standard washer (so not good for families), the legs are a bit wobbly (though they do have suction cups on the bottom to add stability), and the company that makes it doesn't have a great reputation with the Better Business Bureau (the main complaint being that their customer service sucks - I had no problems with them).
Would be ideal for: camping/long vacations in places without laundry facilities, knitters (way easier on hand-knits than a standard washer!), primary laundry machine for one person or a very environmentally dedicated couple, secondary laundry machine for a family (I could see kids either loving or hating this thing).
Spin Dryer
Reason I bought this model: Its capacity matched the Wonder Wash (12.2 lbs wet laundry, which is about 5.5 lbs dry) and it was cheap compared to other models with similar capacity.
Pros: Uses very little electricity, takes 3 minutes or less to dry clothes, cheap compared to similar models ($135), way cheaper overall than a standard dryer, just light enough to be luggable.
Cons: Makes slight monster truck noises when used on pergo (I can't speak for other flooring types), comes with a boatload of non-eco-friendly packaging, doesn't dry clothes 100% (this is standard for spin dryers, though - it dries them enough that they can be hung up for a few hours to overnight to dry). Also, the instructions inaccurately portray the size of container you need to catch the water from the machine's spout (it takes a proper mixing bowl, not a little cup like in the picture, which my kitchen floor found out the hard way).
Would be ideal for: someone using a hand-crank washer as their primary washing machine, someone wanting to cut down on their dryer-related energy costs/usage/time wasted (after 3 minutes in the spin dryer, clothes only need about 10 minutes in an electric/gas dryer to be fully dry, instead of a full cycle), and once again, knitters. I could also see kids really liking this machine, what with its monster truck noises.
