ABSTRACT:
A swimming pool vacuum cleaning apparatus having a flexible platform, including an apertured central portion adapted for interconnection with a suction line, a pair of outboard roller assemblies for maintaining the end portions of the platform in a spaced relationship with the pad bottom and a pair of inboard roller assemblies which are readily vertically adjustable relative to the platform so that the spacing between the central, suction portion of the platform and the pool bottom can be quickly and easily adjusted during the pool cleaning operation. The inboard roller assemblies as individual units can also readily be attached to certain types of existing cleaning apparatus to provide an improved vertical adjustment feature.
