Polaris Zodiac Idler Wheel, Zodiac Polaris 180/280/360 (C16) is a replacement idler wheel from Polaris/Zodiac, made for pool cleaner service, repair, and ongoing maintenance. This replacement part supports smooth movement and tracking on compatible Polaris/Zodiac cleaner assemblies. It is a practical option when an existing component is worn, cracked, missing, or no longer allowing the cleaner to move and function as expected. Because automatic pool cleaners rely on small moving parts, fittings, wheels, valves, and water-driven assemblies working together, replacing the correct component can make a noticeable difference in day-to-day performance. Replacing a worn idler wheel can help restore cleaner mobility and reduce drag caused by cracked, flat-spotted, or damaged wheels. Use the listed part number, C16, along with your cleaner model and existing part configuration to confirm fit before installation. Designed for compatible Polaris/Zodiac cleaner repair and maintenance Helps restore cleaner movement, water flow, or component alignment Useful for service professionals and pool owners replacing worn parts Supports a more cost-effective repair compared with full cleaner replacement Match part number C16 to the original component before ordering
