and what about the energy rating?
Well.....maybe it's funny to see the machine in operation, but can't imagine that it does really a good cleaning job just with warm water and a bit liquid detergent that is sprayed arround like a lawn-sprayer with low pressure at about 45°-60°C!?
So, to get normal items clean you will need to pre-treat them, I'm sure, like pre-rinsing and maybe pre-soaking and scrubbing them, which will cost more water and more energy.
Also I can imagine that this little "machine" will use twice as much water per set of dishes than a big electric dish-washer does, am I right?
I personally have a nice dish-washer from 1952, "Self-Maid" it's called, that also has a transparent acrylic dome, so one can watch the funny action inside, but this machine has a heater and thermostat as well as an electric motor with impeller action and does a really good job although it needs only 4 minutes washing time per load!
