FAQ

This belt kit fits Polaris pressure-side pool cleaners in the 360 and 380 families, including Polaris Vac-Sweep 360, Polaris Vac-Sweep 380, 360 BlackMax, and 380 BlackMax models. If your cleaner uses belt kit part number 9-100-1017 or 91001017, this is the correct replacement reference to verify against your unit.
This kit matches part numbers 9-100-1017 and 91001017. Those numbers are commonly used for the Polaris small-and-large belt replacement kit for 360 and 380 cleaners.
The 9-100-1017 kit includes two drive belts: one small belt and one large belt. These are the two belts typically replaced together on compatible Polaris 360 and 380 pool cleaners.
Typical symptoms include reduced wheel movement, intermittent drive operation, weak or uneven cleaner travel, wheels that stop under load, or a cleaner that no longer moves through the pool as expected even when water pressure is correct. Worn, stretched, cracked, or glazed belts are common causes.
Yes. Replacing both the small and large belts together is usually the best practice on Polaris 360 and 380 cleaners. When one belt is worn, the other often has similar age-related stretch or wear, and replacing both at once helps restore more consistent drive performance.
Belt replacement is generally a moderate repair for most pool owners. It usually involves opening the cleaner body to access the drive mechanism, removing the worn belts, and installing the new small and large belts in the same routing. Basic hand tools such as screwdrivers are typically all that are needed. Plan on about 20 to 40 minutes if you are familiar with the cleaner, or a little longer for a first-time repair.
Before installing the new belts, inspect the drive system for seized wheels, worn pulleys or gears, debris in the drivetrain, and signs of internal drag. Also confirm the cleaner is receiving proper water pressure, since poor performance is not always caused by belts alone. Cleaning out debris and checking for worn moving parts can help the new belts last longer.
