Dolphin Diagnostic Advantage Robotic Pool Cleaner

Pros: Cleans pool walls and waterline well; helps keep pool clean; saves cleaning time

I purchased the Dolphin Diagnostic Pool Cleaner three years ago and I have yet to get a full summer’s use out of it. It stopped working towards the end of the first summer so I sent it back to be repaired under warranty. I received it back for the ...

Pros: cleaned well when new
Cons: only lasted 3 seasons Heavy to lift

I paid over $1000.00 for a Dolphin and just barely got 3 season's of use when it began to quit after running only 10 minutes. I finally sent it in for repair and was told that the motor unit was bad, not covered by warranty, and it would cost $569.00 to replace it. I decided not to repair it since a refurb unit was only slightly more and was informed that it would cost me $100.00 to get it back ($60.00 diagnostic fee and $40.00 shipping). They can keep it and I will purchase a different product.
When the Dolphin was new, it worked great. However, it was heavy to lift it out of the pool (my wife could not lift it) and once out, part of the contents of the bag would end up back in the pool.
