FAQ

This belt kit is compatible with Polaris 360 and Polaris 380 pressure-side pool cleaners. It also fits the Polaris 360 BlackMax and Polaris 380 BlackMax variants.
This replacement belt kit matches part number 9-100-1017. This number may also be referenced as 91001017.
This kit includes one small belt and one large belt. These are designed to be used together in the drive system of compatible Polaris 360 and 380 cleaners.
Worn belts can cause the cleaner to move poorly, stop driving, lose wheel movement, or clean inconsistently. If your Polaris 360 or 380 is powered by water pressure but the internal drive action seems weak or the unit is not traveling normally, the belts are a common item to inspect.
Belt replacement is a moderate repair for owners comfortable opening the cleaner housing. You will need to remove the unit from the pool, open the case, access the drive section, and swap the small and large belts. A screwdriver is typically the main tool required, and the process generally takes 20 to 40 minutes depending on the condition of the cleaner.
Yes. Before installing new belts, inspect the drive mechanism for debris, worn pulleys, cracked gears, or stiff wheel movement. On pressure-side cleaners, verify that the unit is receiving proper water flow and that the internal components turn freely, as restricted movement can shorten the lifespan of your new belts.
