I suppose it technically could clean clothing too, albeit you probably can't fit very much without balling or layering stuff up too much to get it clean. A clothes washing machine is probably more efficient for this purpose.
Although for countries where laundry machines are typically in the kitchen, a theoretical hybrid machine would be interesting (if it worked well, and the dish specific stuff could fold away compactly), but in practice multi-function machines like that rarely seem to turn out well.
