Pentair Sta-Rite GW9500 Cleaner Vacuum Skirt (GW9508) bussfuses and 8600 series applications whereThe vacuum skirt is a key contact point that helps the GW9500 maintain suction and guide debris into the cleaner path. Over time, the skirt can become stiff, torn, or misshapen, reducing how well the cleaner seals against the pool surface.
