Help - Dolphin From Costco Works For 10min And Then Stops !

[CarlD]

hey Carl
didn't you find that if the chemistry was off and the water temperature was very low, the dolphin pretty much didn't work?

No, I found they gave me that as a line why it wouldn't work. They gave me a bunch of bizarro numbers that they "required" for it to work, like super-low pH. In fact, according to the US rep's nonsense, my Dolphin should NEVER have worked. It was all BS (Barnyard Slush). Something went south.

The manuf rep in Israel didn't give me that at all. He was very cooperative.

They actually sent me a complete new (not overhauled) unit and that works. But I, in the interim, bought a Blue Diamond, and that works very well, with a few caveats:
1) I have to pull my ladder out because it gets stuck under it. It only takes 30 seconds but it shouldn't happen.
2) You cannot program it to always climb walls. You need to start it, let it run and start to move, then hit the change-direction key on the remote and it will then climb the walls every 3 or 7th time (I forgot which). It's a minor pain.
3) They rather deceptively advertise that you can use it on any shape if you have the remote. What they don't tell you is you must guide it complete for odd shapes. It only is set-and-forget for a rectangular pool, which luckily I have.
4) You have to let it sit in the water until the foam rollers soften, and leave it 20 minutes after it completes to cool.
5) Compared to the Dolphin the programming is stone-age.

OTOH,
1) the bag works just as well as the Dolphin's but is 10x easier to clean because it's a thin, single layer.
2) it cleans the pool in 1/4 to 1/3 the time.
3) it weighs far, far less
4) it always works....that's the bottom line.

BTW, you should know that all of the robotics were originally one company and the others are all split-offs, and all the units are supposedly made in Israel, or were. So they all bear a definite family resemblence.
