I could use some help from those that know much more than me about pool vacuums. We have a brand new, in-ground, fiberglass pool - installed in March. After the initial start-up I've been pretty hands-off with it. I test twice a week and throw the Dolphin (Explorer E30) in once a week (maybe twice if it's windy). Today the power supply died on the Dolphin just over two months after we bought it. Would I be crazy to consider returning it to Home Depot and replacing it with a Pool Blaster? My pool is small - 12x25 (around 7,000 gallons) with two seats and stairs that the robot doesn't clean anyway. It has a lot of curves that the Dolphin struggles with, too, so I wind up brushing around the perimeter of the bottom before running it anyway. I don't mind working on the pool because I find it relaxing, but I don't want caring for it to become too much of a chore. For the price of the Dolphin I could buy a Pool Blaster and the volleyball/basketball combo I've been eyeing for the kids and still come out about $500 ahead. Would I be crazy to replace the Dolphin with a handheld vacuum? Are there any positives or negatives I'm overlooking?
