I found a guy selling a like new Dolphin Z5 that he says has only been used 8 times in 2 weeks for $850. He has the receipt from epicpoolsupply which he says can be used to get the warranty, but I'm not sure how that would work. He has a vinyl pool that he says the robot doesn't work well in and that's why he's selling it. I can go to his house and see that it functions properly in his pool before I buy it. It comes with everything it was originally shipped with -- caddy, remote, cleaner, receipt and warranty card.
Do you think this is a good deal? I'm a little concerned about the warranty, but maybe I can still get it. Please let me know what you think. I don't want this to get away if it's as good of a deal as it seems like. Thanks!
