A new and improved swimming pool vacuum apparatus includes an extensible handle assembly which serves as a handle grasped by an operator and which supports a vacuum motor assembly. The vacuum motor assembly is used for providing vacuum power to a vacuum head assembly which contacts the bottom and the walls of a swimming pool. The vacuum head assembly is also supported by the extensible handle assembly. An electrical conductor assembly, connected between the vacuum motor assembly and a source of AC power, is used for conducting electrical power from the source of AC power to the vacuum motor assembly. The electrical conductor assembly includes a ground fault circuit interrupter assembly for interrupting electrical power flow from the source of AC power to the vacuum motor assembly in the event of a short circuit. The extensible handle assembly may include a plurality of handle units connected together in telescopic fashion and also includes an electrically insulating hand grip member.
