HRSDENNIS,

Not to hijack this thread, but the thought of numerous pinholes in my liner from my automatic vacuum terrifies me. I have the Kontiki II from barracuda/zodiac, which is similiar to the Ranger model. I always monitor it, because it has the occasional tendency to get hung up on the stairs. It doesn;t seem to have a tremendous amount of suction, and only has the rubber disc that stirs up the debris. I distinctly asked the pool store if this vacuum would damage my liner, and it was recommended for above ground pools. Are you telling me that I have something else to worry about now ? or do the pinholes come from any particular type automatic cleaner, like the robotic ones?

thanks
