These small but critical gears transfer rotational force within the cleaner’s drivetrain, allowing wheels and internal components to move smoothly and consistently. Over time, drive gears naturally wear from constant rotation, debris load, and water exposure. When gears become worn or stripped, the cleaner may lose traction, hesitate, or stop moving altogether. Replacing them early helps prevent larger transmission failures. * * * ## What the Polaris R0518800 Drive Gear Kit Does Inside a Polaris pool cleaner, drive gears play a key role in converting water pressure into mechanical movement.
