Perfect for Polaris 280 and 480 robotic pool cleaners with the same specifications as the Polaris K13 net. Over time, zippers outlast scratches and won't get clogged not. Large capacity stringer bag with reinforced stitching and ultra-fine mesh to capture even the smallest debris. The specific shape of the mesh prevents debris from falling out when the robot vacuum is stationary. The hook-and-loop attachment on the hose makes it easier for debris to pass through the filter. Package contents: 1 x pool robot filter bag. We only sell pool robot filter bags, not other items in the picture.
