The folks that make the Dolphin need a good class action lawsuit against them for false advertising. First, there is no way the damn thing can "learn" your pool. I don't think it has any memory chips, but that is just an opinion. How could it learn anyway. If the water level changed slightly it would have to relearn. If you put it in the pool in a different place each time it would have no way of knowing where it was and would think it was a different pool.

Also, they claim in their ads and on their box that the unit includes a free extra filter bag. While maybe techincally true, it is not what you would expect rather a cheap paper disposable bag. This is pattently a case of gross disception if not outright lying. I would never buy another product made by that company and would suggest that others think twice. I just wish others bought it from a place that would take it back.
