Zodiac 39-401 Single Side Wheel Polaris 3900 Sport

Product Description

The ZODIAC 39-401 is a genuine OEM single side wheel replacement designed for Polaris pressure-side automatic pool cleaners. This part restores proper drive and traction to the cleaner head, keeping the unit moving efficiently across pool surfaces. Made from durable plastic, it is a direct factory replacement that maintains the original performance specifications of the cleaner. Pool service technicians and experienced DIYers install this part as a routine maintenance replacement when worn wheels cause erratic movement or reduced cleaning coverage. At 0.35 pounds, the part is lightweight and straightforward to swap in the field.

This single side wheel is intended for residential pool cleaner service. It fits the Polaris 3900 Sport automatic pool cleaner and is used when the existing side wheel shows wear, cracking, or reduced grip that affects the unit's travel pattern across the pool floor and walls. Regular wheel inspection is a standard part of seasonal pool equipment maintenance, and replacing worn wheels helps extend the service life of the overall cleaner assembly.
