ABSTRACT:
A hydrofoil attachment for swimming pool vacuum cleaner heads provides downward thrust during the pulling stroke. The hydrofoils pivot so as not to impede the pushing stroke. The hydrofoils are pivotally supported on a laterally extending rod. The rod is supported by triangular plates which mount on the axles of the wheels of the vacuum cleaner head.
