Hi - Not sure where to post this, but has anyone come across a device that collects water from about 18" down? My old knees & back are getting tired of this daily ritual... The cup would have to turn over once at that depth, otherwise I could easily make my own I think. Tried googling & only found a device on a 24' pole for taking water horizontally across a current....tks! (such a device could be a money-maker if every home had a pool imo! I'd pay up!)
