April Fools Joke
I think the joke is calling it a "Fully Automatic Washing Machine".
They could just as easily have called it an "Automatic Washing Machine", which would make it distinguishable compared to, say, a "Semi-automatic Washing Machine" (i.e. a twin-tub).
With "Fully...", I expect the machine to load itself, dose the detergent, wash, rinse, spin, dry, iron, fold, place in wardrobe/cupboard/chest-of-drawers, clean the dishes, put the bin out, wash the floor, and feed the cat.
