Thanks. I currently use the triangular bristle head, too.

Can't rationalize the wear difference on the liner between robotic (aquabot or dolphin) or ATV type (polaris) and roller vac. It seem like 6 of one and half dozen of the other.

My husband's input is this (he who does no pool maintenance other than use leaf blower around concrete decking before a party): hire some cute young guy in a Speedo to do it. HMMMM. Not sure at all what he's thinking.

Anyway, off to WalMart to get a roller vac head.
