PS: As an example, note the sheet-metal construction. In an industrialized country we would laser-cut all these parts. If you wanted to make this in an area with less infrastructure you might use a template and carbide gas torch to cut out the large shapes, then a hand punch to make the screw holes. More labor intensive, but still doable.
Probably sell well in a lot of developed world markets for people who just want to limit their electricity use, live away from the grid, have less reliance on complicated electronics, or minimize money use in an expensive society.
Oh and separate your laundry. Don't throw towels, blankets, and clothes in all at the same time.
As for separating colors - in my life I've had a piece of clothing stain other clothes 2 or 3 times. Once I put some white shirts and they came out pink because of another red shirt. Funny thing is, the pink was very uniform, so it looked as if the shirts were originally pink.
If my washing machine breaks, I'll get a second hand one. If I get a brand new washing machine, it will have to have a manual mode where I can set the desired program manually. For example, what is "towel setting"? If I can't see and modify the setting (e.g., A temperature for B minutes at C RPM, then D temp for E min for F RPM, etc.), I wouldn't use it.
If you wash items of different weights, fabrics, etc. together the load can get unbalanced more easily. Such as as single heavy towel or jacket in with a bunch of light synthetic items.
The "towels" setting uses warmer water and faster spin speed but an overall shorter cycle (at least on my washer) compared to the "normal" cycle. This probably presumes that towels usually are made of cotton and aren't very dirty.
I agree that a fully manual mode would be nice. My washer (LG) doesn't have that but by knowing what the various cycles and optional settings (e.g. soil level, extra rinse) do you can get pretty close to what you want.
Enter "why wifi on your washing machine makes sense"
I was always confused doing laundry in the US. Warm cycle or cold cycle?
I have 30C, 40C and 60C depending on what I'm washing. I probably have more programs, but never use them. For pillows and stuff I adjust spinning, from 1200 to 400 RPM. And I use special short, low rpm handwash program for wool.
(Side loaded ofcourse, that way the dryer can be on top)
Top loader uselessness is my pet peeve.
Front loaders (just like one in video) wring clothes as they spin. The result difference is day and night.
Also if you pay close attention you'll notice that things don't come fully clean (old machines didn't either) just "clean enough". Throw some well used dog bedding in with your shirts and this fact might become more readily noticable. So it makes sense to wash like-use with like-use for that reason alone.
Wash.
Is clean?
Yes: put in drier.
No: GOTO wash.
Same thing for dishwashers, the “eco” program is often not the best especially if you have an “auto” one.
But for machines that have a table showing power and water use, it’s never the most efficient one (in all the ones I checked). There is always a better program, it’s usually called “auto”.
Maybe it’s different in North America, idk what the rules are there.
Eco is just the standard program they have to ship and must use for the energy efficiency rating.
But still I'm inclined to agree with the general sentiment of not micro optimizing things in ways that make people's lives more difficult.
I understand they had a very good idea to begin with, and more importantly their heart in the right place And then further made it better with more input.
Reading the comments here the better solution for us is probably not to go back to "dumb" washing machines, but to regain control of how these machines are designed, for who and for what.
I'm thinking about Linux, which can be stripped down as small and nimble as needed to run a single board micro controller, or be large as needed to have everything to run an enterprise service. Being able to do the same with a washing machine would absolutely change their usefulness and place in our society.
I don't know how it could start, perhaps with an IKEA washing machine that actually needs assembly, for users to then tweak the parts, start comminities so we get at least in a KALLAX situation ?

The metal design in the article is still more flexible and durable. I also assumed the Japanese version would be targeted at disaster situations and/or remote mountain areas and be more repairable, but the cost saving part seems to be a major selling point.
The clothes falling down from the upper half is described on the slides, so I assume the rotation isn't fast enough for the clothes to stick to the walls, or it has an elliptical rotor to make sure there a speed difference ?
(edited as I'm not sure how it exactly works)
I lived off-grid and did all of our laundry, a family of four (including a baby in cloth diapers), by hand, even in the winter (below -20F).
You know what works as well? A wash tub and a stick. Or a bucket and plunger. Or a posser if you're really fancy. I used a 30 gallon garbage can and a hand-carved posser. In mild or hot climates you can just stomp on it.
Same principle: Draw water, add cleanser, agitate for a couple of minutes, let it soak, return at some time in the future, agitate again. Remove laundry and let drip dry while you draw fresh water (mangles and spinners speed this up and are more effective, but not necessary). Squeeze wet laundry at lowest point where water has gathered. Repeat entire process with clean water, then lay it out in the sun prioritizing any sides with stains.
The secret sauce of clean laundry isn't how you agitate the laundry. It's just time and chemistry.
Water access, cleansing agents, and patience are fundamentally more important than providing "revolutionary" contraptions. It's the same difference between teaching people about no-knead bread and giving them hand-cranked stand-mixers. One solves the need for intensive manual labor and the other doesn't, but introduces a new point of failure.
And even importing enzyme-containing detergent is unnecessary. Plant ash (a source of alkali) and aged urine (a source of ammonia) are all you need to create what's known as bucking lye which cleans just as effectively and uses byproducts that they themselves produce by default. Residual stains are removed via UV from sun drying.
There's absolutely no need to complicate this.
So much is possible if you just look at how nature, in one way or another, can do the work for you. No knead bread (or, better, periodic stretch and folds over the course of a few hours) is a perfect example. Or making a composting toilet/latrine by just adding sawdust, ash etc. Or simple and cheap rocket stoves that burn the smoke. Or cover crops and cultivating soil structure and microbes. Etc
The key for what you shared (and, i suppose this machine) is how little agitation you actually need, and how there's plenty of ways to do it with no fancy equipment. Can you share more about your experience, or even share some links, about the amount of agitation needed, how "cleaning" actually works (you said time and chemistry - but how?), and how to make effective, low-cost detergents anywhere?
Thanks!
For many reasons, I expect to see a lot of new products and solutions going against the main trends of locking down the user, planned obsolence, rent seeking from buyers, and limiting their choices.
Imagining a company shipping the home appliances equivalent to Frame.work laptops: open, reparable, hackable, and upgradable. I would happily connect them to my home wifi, program them the way I want, and have one hub that allows me to monitor health, upgrade firmware, control functionality.
I think within no time it will be modded with motors, maybe salvaged from broken electrical appliances and it will come full circle.
It might be down a few hours every day, or completely cut for days after storms or infra degradation, or the current fluctuate too much for delicate electronics. Many places could also get hold of a gasoline generator.
These kind of variations could require more thinking on the design, but being able to use electricity when available and hand power when needed would be the best.
Ideally the people on the ground thinking about their specific issues and having open ways to adapt the machine for it opens the door for many kind of evolutions.
Designing stuff for real humans to use, is really difficult, and really humbling.
In my experience, defense contractors really have to take the user context into account. It can be life or death. I used to work for one, and seeing the stuff come back from the field, was a lesson in humility.
