Not a washing machine, and not sold as one. It is for the small loads where the alternative is a sink: socks, underwear, a baby’s clothes, a shirt in a hotel room.
It takes over the part of hand washing that is actually work. Ultrasonic vibration lifts dirt out of the fabric and an alternating turbine rotation moves the water through it, so nothing is being scrubbed or wrung. You still fill it, and you still rinse afterwards.
Five litres, ABS with a soft silicone body, and it folds flat into a drawer or a bag. USB power is the point of it: a power bank, a car socket or a wall adapter will run it, which is what makes it useful in a caravan or a room with no plumbing. One 30-minute cycle, then it shuts itself off.
