Searched for this and only found one thread with limited posts so thought I'd ask anyway:
Gunite pool style roller vacuum: OK to use with Vinyl liner IG pool? Google searching has turned up mixed responses. I used one on a concrete pool for years, and it amazes me how darn slow it is to use the crummy lightweight, triangular "vinyl pool" vacuum head. Our PB says it's fine to use the roller style. I'd like to know how many TFP members do this, and please share your opinions and experiences.
