Zodiac – Polaris Quattro Sport bottom chassis – R0837900

The Zodiac R0837900 is the genuine OEM bottom chassis (lower body frame) designed specifically for the Polaris Quattro Sport and Quattro P40 automatic pool cleaners. This structural component forms the base of the cleaner unit, housing and supporting the internal drive and turbine mechanisms that power the cleaner’s movement across the pool floor and walls. The chassis is moulded in blue plastic and features a distinctive opening on the bottom front centre, which functions as the primary dirt and debris intake port — allowing the cleaner to efficiently vacuum leaves, sand, and fine particles directly from the pool surface.

As the foundational lower structure of the Quattro Sport cleaner, this chassis must be in sound condition for the unit to operate correctly. Cracks, fractures, or deformation of the chassis can compromise the seal integrity of the internal drive system, reduce suction efficiency, and cause erratic movement patterns. Replacing a damaged chassis with this genuine Zodiac part restores the cleaner to its original factory specification, ensuring all mounting points, turbine seats, and wheel drive channels align precisely with the intended components.

Technical characteristics and compatibility

This chassis is listed by Zodiac as a warranty-replacement component, meaning it is primarily intended for warranty servicing and authorised repair scenarios. It is manufactured to the exact dimensional tolerances required for the Polaris Quattro Sport and Quattro P40 pool cleaner models. The blue colouring is consistent with the original factory part. The front-centre intake opening is an integral feature of the cleaner’s debris collection design, directing suction flow into the filter bag or debris canister.

Because this is a structural housing component rather than a consumable wear part, it is not a routine maintenance item. It is the correct replacement when the chassis itself is cracked, broken, or otherwise physically damaged. All internal components such as the cyclonic turbine, drive train, and wheel assemblies are separate parts and are not included with this chassis.

Suitability and application

This part is exclusively compatible with the Polaris Quattro Sport and Polaris Quattro P40 automatic pool cleaners manufactured by Zodiac. It is not a universal component and is not designed for use with any other pool cleaner model or brand. It is suitable for pool owners and service technicians undertaking a structural repair or warranty replacement of a Quattro Sport unit. Given that this is classified as a warranty-only component, availability may be subject to lead times — typically around three to five weeks as a special-order item. Buyers should confirm their exact cleaner model before ordering to ensure full compatibility.
