This vacuum head is designed to clean fibreglass and vinyl lined swimming pools. Its unique triangular shape easily cleans corners and its bumper perimeter protects the pool liner. The angled brush design allows for fast and effective debris pick up while its see-thru constructions lets you see it being removed. The enclosed weights keep the vachead submerged. The vachead fits standard 1 1/4" and 1 1/2" vacuum hose and has a swivel connection, which provides superior maneuverability without any hose tangling. The snap-adapt handle will fit standard 1 1/4" telescopic poles.
