"Works great with AG liner install. 33' ovals that would give them troubles with wrinkles in the past--no problem for the G20. Sucked liner tight to pool wall and sand bottoms."
"No "pucker" left behind where the tube was behind the liner. Slides out easier than the Q vac tubes and because it doesn't 'collapse' behind the liner."
"Fewer 'go backs' on both AG and IG liner installs due to the G20."
"IG and AG Liners set more efficiently than in the past."
