For robot cables, depending on the design of the connector on the motor end of the cable, are currently referred to as assembly or DIY enthusiasts. On most older robot models, the cord has been installed through the small hole in the side wall of the cleaner. The opening on the side was too small for the cord to pass through with the plug at the end.
For DIY: To improve the plug design, a moulded plug has been created that has been permanently attached to the motor end of the cable. Instead of getting through the small hole in the side, the cable entered through the top of the cleaner and was simply plugged into the top of the motor. Since this cable design was much easier to install, it was called "DIY" for Do It Yourself at the end of the manufacturing code of the cable.
Compatible with most models: replace your old cable with this high-quality replacement cable that makes your pool robot good as new! This replacement cable and swivel works with the following older Dolphin Robotic Pool Cleaners models: Nautilus (Old), DX3, Advantage Plus, Endeavor, Atlantis, Primal X3, DX3S, Orion, M3, Saturn (Old), Quest and Neptune.
