Zodiac - Quattro Sport right gearbox side brush - R0838400

Zodiac – Quattro Sport right gearbox side brush – R0838400

The Zodiac R0838400 is the genuine OEM right-side gearbox brush designed specifically for the Polaris Quattro Sport (P40) pressure-side automatic pool cleaner. This component forms an integral part of the cleaner’s drive and scrubbing system, working in tandem with the gearbox mechanism to deliver consistent side-wall and floor scrubbing action as the unit travels through the pool. As a factory replacement part, it ensures the cleaner continues to operate at its designed performance level without compromise to cleaning coverage or movement efficiency.

The gearbox brush assembly on the right side of the Quattro Sport is responsible for converting the rotational output of the internal gearbox into direct scrubbing contact with pool surfaces. Over time, bristle wear reduces the effectiveness of this contact, leading to diminished cleaning performance and potentially uneven movement across the pool floor and walls. Replacing the brush with this genuine Zodiac part restores the original scrubbing force and directional balance of the cleaner. The component is engineered to exact factory tolerances, ensuring correct fitment and reliable engagement with the gearbox drive system.

Compatibility and installation context

This brush is specifically designed for use with the Zodiac Polaris Quattro Sport and Quattro P40 pressure-side automatic pool cleaners. It is important to note that this is the right-side gearbox brush; the left-side version is a separate part. Always confirm the side required before ordering to avoid returns. Installation is a straightforward replacement procedure suited to pool owners comfortable with basic pool cleaner maintenance — no specialist tools are required. The part connects directly to the existing gearbox housing on the right side of the cleaner body.

Suitability and buying guidance

This replacement part is suitable for any in-ground pool using the Zodiac Polaris Quattro Sport or Quattro P40 pressure-side cleaner. Pressure-side cleaners of this type are typically used with in-ground pools of varying shapes and sizes and require a dedicated pressure line or booster pump. If your Quattro Sport cleaner is showing signs of reduced scrubbing effectiveness, uneven movement, or visible bristle wear on the right-side brush, the R0838400 is the correct OEM replacement to restore full cleaning performance. Using genuine Zodiac parts is recommended to maintain compatibility and longevity of the cleaner system.
