For vinyl liner pools there is no better vac head than the Hayward Super Vac. Strong and durable see through molded plastic body with a thick pole attachment handle featuring a metal pin not plastic like less expensive vac heads.
It also features the thickest brush set of any pool vacuum out there. These brushes are thick and strong to pull up algae but soft on the liner and last considerably longer than traditional vac heads.
These are the vacuums that our service techs use out in the field for their excellent durability and superior suction.
