This is a most excellent place for technology news and articles.
I thought they go off of weight. How could they tell how dirty they are?
Not a washing machine technician but I guess an optical sensor measuring the light permeability of the water (over time) should do the trick. Similar to a smoke detector. But I guess weight is a thing as well.
That makes sense, wouldn't be that complicated that way.
