I'm getting a Dolphin Z5. Can the caddy, robot and power supply stay outside all summer? The instructions say to keep it in a cool/dry area, out of direct sunlight and excessive heat. I was hoping to keep it outdoors next to my pool equipment but wonder if some sun and rain will damage it? I don't have much room in my shed, its a little far from the pool and I think it would be hotter in there than being outside. Where do you keep yours?
