Absolutely, and I am very pleased with mine which is powered by a bank of cabin roof mounted solar panels,although it is a bit inconvenient only to be able to do the washing during the daytime when I am sailing.
At night there is an inexplicable inadequacy of electrical power.
Not sure SWMBO would take to the idea.
How can I persuade her that a little Japanese girl with an electric bucket is a useful addition???
(Not that I want the bucket, mind...)
Used to have one of these electric washing buckets when I was at Uni in '78 - made by Black & Decker! Worked very well (and didn't drill holes in yer socks) - good ideas get recycled...
The last time I was in Japan the toilet had a set of pe-programmed sequences for different situations... I will leave the diagrams to your imagination, but when the warm air fan started to blow I realised what a "road to damascus" moment was.
QUOTE (same wonderful site): Although not all person forget to pour water after using a toilet, washing a hand tends to forget.
If a lever is turned and water is poured, since water will come out from the water tap which is at hand, those who have forgotten to wash a hand will also wash this toilet.

Follow this link The same company also make an "detergent zero washing machine" which looks very high tech but whether it actually gets clothes clean or not is anybody's guess.
