Please keep in mind that there are two sides to every story...
The same gaskets and O-Rings that are under that horrible water pressure are the same gaskets and O-Rings that will dry up when the Robot is taken out of the pool...
I have three dolphin robots... two I bought used and have to be at least 15 years old... Both of them have been underwater at rent house pools for about 5 years... They don't come out except when the bag is being cleaned. There is no doubt that the plastic has faded and they look bad, but they keep right on ticking...
The problem with Bombardiers comments is that he only sees one side of the story... I am sure what he says is absolutely true, but what kind of pools have these damaged robots been in? I doubt they were all TFP pools, so we have no idea if the pH was really low or if they were in the pool when powered shock was added or what other chemicals were added while the robot was in the water...
The other part of the story we don't know is the true failure rate.. If we had 10 robots all left in a pool for a year, and eight of them failed, then that would be a pretty strong indication that being constantly under water was the main cause of their failure.. On the other hand, if we had a 1,000 robots being kept underwater and only 8 of them failed that would prove the opposite... I guess my point is that the Bombardier is a repair guy... as such almost everything he sees is bad...
