Abstract
A buoyant power cable for electrically connecting a submerged robotic self-propelled pool cleaner to an external power supply that is subject to foaming coils in the floating portion that are not readily opened and interfere with the desired movement of the pool cleaner is provided with a separate flexible sleeve of polymeric material or an extruded coating of a foamable or solid polymeric composition having a relatively low coefficient of friction as compared to the surface of the floating cable over the portion of the cable that floats on the water's surface so that when one or more loops are formed in a portion of the cable covered by the sleeve or coating, the contacting surfaces easily slide over each other to permit the removal of the loops and the free movement of the pool cleaner.
