Fluidra - Brush Drive Gear with Ball Bearing (VAX) for TRX 8500 iQ

Fluidra – Brush Drive Gear with Ball Bearing (VAX) for TRX 8500 iQ

This is the genuine Fluidra replacement brush drive gear with integrated ball bearing, designed specifically for the VAX brush system fitted to the Zodiac Vortrax TRX 8500 iQ (EU) commercial robotic pool cleaner. It forms a critical part of the brush transmission train, transferring rotational force from the drive motor to the cleaning brush roller so the robot can effectively scrub pool floors, walls, and waterlines.

How It Works

In the TRX 8500 iQ’s drivetrain, the brush gear meshes with the motor’s gear train and drives the cylindrical brush roller into rotation against the pool surface. The integrated ball bearing ensures smooth, low-friction rotation under continuous wet conditions, reducing wear on surrounding components and maintaining consistent brushing performance over time. A worn or damaged gear will cause loss of brush rotation, reduced cleaning effectiveness, and can lead to accelerated wear on adjacent drivetrain parts.

Compatibility

This part is engineered exclusively for the Fluidra Zodiac Vortrax TRX 8500 iQ (EU) robotic pool cleaner (Fluidra model code WR000597), and is matched to the VAX brush specification. Always verify your cleaner’s model code and brush type before ordering to ensure correct fitment — this gear is not interchangeable across all TRX variants.

Why Genuine Matters

As an OEM Fluidra spare part, this brush gear is manufactured to the exact tolerances required by the TRX 8500 iQ’s transmission system. Genuine parts maintain the integrity of the gear mesh and bearing seat, protecting the motor and drive assembly from premature failure. Choosing genuine Fluidra ensures warranty compliance and reliable performance in demanding commercial pool environments.
