This vacuum head is designed especially for vinyl lined swimming pools. This vachead's unique brush pattern channels debris directly to the suction for easy removal. The side bumpers have brushes that help clean and protect the pool liner. The enclosed weights keep the vachead submerged. The snap-adapt handle will fit standard 1 1/4" telescopic poles. The vachead fits standard 1 1/4" and 1 1/2" vacuum hose.
