AN AUTOMATIC POOL CLEANER ACCESSORY

摘要

An automatic pool cleaner accessory is provided comprising a tubular assembly for connection to, or for inclusion in, a pool cleaner suction hose. The tubular assembly includes first and second coaxial tubular members which are relatively rotatable about a common axis and means for automatically effecting angular movement of the first tubular member relative to the second tubular member about said axis generally to vary the relative angular positions of the two members. The accessory operates on the basis that an automatic pool cleaner suction hose will generally have asymmetric portions in its length which are other than perfectly straight and the effect of rotating the hose about its own axis at a position remote from the suction head will have the effect of changing the influence that these asymmetric portions have on the "random" movement of the pool cleaner.
