FAQ

This belt kit is designed for Polaris pressure-side pool cleaners, including the Polaris 360 and Polaris 380 (Vac-Sweep 360 and Vac-Sweep 380). It is also compatible with the 360 BlackMax and 380 BlackMax versions. Please verify that your cleaner requires belt kit part number 9-100-1017.
This replacement kit corresponds to part number 9-100-1017, which is the standard reference number for this small-and-large belt set used in Polaris 360 and 380 cleaners.
The 9-100-1017 kit includes one small belt and one large belt. These two components work together within the drive system of Polaris 360 and 380 pool cleaners; replacing both simultaneously ensures consistent belt tension and optimal cleaner movement.
Typical symptoms include the cleaner moving slowly, stopping intermittently, struggling to climb walls, or wheels failing to drive correctly despite adequate water pressure. Worn belts may also appear stretched, cracked, glazed, or loose. If your cleaner has a good water supply but exhibits weak or inconsistent drive action, the belts should be inspected.
Yes. Since this kit includes both the small and large belts, replacing them together is the recommended approach. Because both belts typically experience similar wear and age, installing them as a pair restores balanced drive performance and prevents the need for additional maintenance shortly after the initial repair.
Belt replacement is a moderate maintenance task. It involves opening the cleaner housing, accessing the drive area, removing the worn belts, and installing the new small and large belts. The process typically requires basic hand tools like a screwdriver and takes approximately 20 to 40 minutes. Before reassembling the unit, inspect the drive components for debris, worn pulleys, or stiff parts that could affect belt longevity.
