Point of order: Pure water is, in fact, a terrible conductor of electricity. Really pure deionized water has resistances up to 20 megaOhms-cm. You could douse your robot in it and it'd be perfectly happy. Until it started leaching leaching ions from the steel, copper, etc. But up until then, it'd be just fine.
It'd be terribly expensive to fill a pool with water that pure, and even more so to keep it that pure... But still, it could totally happen if it meant there was a water game.
