I saw somebody selling the manual when I was googling. Here is my question
Does any of you have one? Is it good enough to buy?

It's seem an interesting idea if it is really working. And if you own a lot of tank.

Get me one too k?

It seriously sounds like a dream...Until I think about those automated kitty litter changers. I have to stop myself there.
