Title: Rotating wear rings for swimming pool whip hoses

Abstract: A plurality of freely rotating wear rings are disposed along a flexible whip hose of the type used for cleaning swimming pools. The rotating wear rings prevent the flexible whip hose from being abraded by the inner surfaces of a swimming pool. The rotating wear rings have long lives, as their rotation precludes significant abrasion upon the inner surfaces of the swimming pool.
