This is the genuine Maytronics grey wheel disc for the Dolphin E20 robotic pool cleaner, compatible with both S1 and S2 motor unit variants (6C series). The wheel disc is the lateral retention and guide component that seats against the drive wheel, keeping it correctly positioned on its axle and ensuring smooth, consistent traction as the robot traverses the pool floor and walls.<\/p>\n
The wheel disc acts as a retaining cover and structural interface between the outer wheel and the robot chassis. It locks the wheel assembly in place, prevents lateral play, and transfers rotational forces evenly across the wheel hub. Without an intact disc, the wheel can shift axially, causing uneven drive, loss of grip, or complete wheel detachment mid-cycle.<\/p>\n
This part is specified for the Maytronics Dolphin E20 and covers both the S1 and S2 motor unit configurations within the 6C platform. The S1 and S2 designations refer to the motor unit generation installed in the robot; if you are unsure which variant you have, check the motor unit label inside the chassis before ordering.<\/p>\n
Replace this disc if you notice the robot’s wheel wobbling or rattling during operation, if the wheel has detached from its seating, if the disc is cracked or chipped from poolside impact, or if routine inspection reveals the retaining face has worn flat and no longer holds the wheel securely on its axle.<\/p>\n
Genuine Maytronics parts are manufactured to the exact dimensional tolerances of the original design, ensuring a precise fit without play or stress on adjacent components. Counterfeit or generic discs frequently differ in bore diameter or disc thickness, leading to premature wheel failure and potential motor unit damage. Using a genuine replacement also preserves any remaining Maytronics service warranty on your robot.<\/p>","protected":false},"excerpt":{"rendered":"
