Zodiac Vortex and Alpha robot brush support strap – navy blue - W1875A

Zodiac Vortex and Alpha robot brush support strap – navy blue

This is the genuine Zodiac brush support strap (pontet) that secures the cleaning brush assembly to the undercarriage of Vortex and Alpha series pool robots. It holds the brush roller firmly in its correct operating position, ensuring full, even contact with the pool surface during every cleaning cycle.

Function and role in the brush assembly

The support strap acts as a retaining bridge across the brush roller, keeping it correctly seated against its mounting points. Without a properly functioning strap, the brush can shift laterally or lift away from the pool floor, causing uneven scrubbing, reduced debris agitation, and premature wear to the brush itself.

Model compatibility

This part is confirmed to fit the Zodiac Vortex 2, Vortex 3, Vortex 3.2, Vortex 3 4WD, Vortex 4, and Vortex 4 4WD, as well as the Zodiac Alpha RA 6300 iQ, RA 6500 iQ, RA 6700 iQ, RA 6800 iQ, and RA 6900 iQ robotic cleaners. Always cross-reference against your robot’s exploded-view diagram (part position 25) before ordering.

Sintomas que indicam a necessidade de substituição

Replace this strap if you notice the brush roller rattling or moving side-to-side during operation, the robot leaving uncleaned strips on the pool floor, or visible cracking, deformation, or stress-whitening on the strap body. A failed strap can also allow the brush to jam against the chassis, stalling the drive system.

Why genuine Zodiac parts matter

An OEM strap is moulded to the exact geometry of the Vortex and Alpha chassis, guaranteeing the correct retention tension and clip engagement. Third-party alternatives often use harder or more brittle plastics that crack in chlorinated water or fail to hold the brush at the precise angle required for efficient scrubbing. Fitting a genuine part restores factory performance and protects the brush and chassis from consequential damage.
