Well, my 7 year old Dolphin Diagnostic might be done for. The impeller motor is shot and I am having a hard time finding a replacement part, but apparently that is a problem with the Dolphin lines, they are not user serviceable for the most part. So I am looking at replacing it with a Kreepy Krauly Prowler 820 because it looks like a similar type of robot, and I already found sites selling parts so that gives me a little piece of mind. I am looking forward to a cartridge style filter vs. the bag and having a swivel cord so it won't tangle up all the time.
Any feedback on that Prowler 820? Alternatives I should look into?
