Oh, I bought one in 2007 and still have it, it's a nice conversation piece, everybody wonders why I have it on the bookshelf!
Anyway I never used it with water as mine leaks!
Ii took an old plastic milk carton and cut some pieces off of it to make fins for mine. I used superglue and had to hold each one straight until it began to bond. They really make a difference in the wash action.
ive got a rare one!
mine has a watertank behind teh filter cover and it fill and empties automaticly!!
unfortunantly the pump broke and it only works dry
