Maytronics Dolphin Ex 10 wheel plug white S1 - M96100021

Maytronics Dolphin Ex 10 wheel plug white S1

The Maytronics Dolphin Ex 10 wheel plug white S1 is a genuine OEM replacement plug designed to secure and cap the wheel hub on the S1 drive platform of the Dolphin Ex 10 robotic pool cleaner. This small but structurally important component seals the outer face of the wheel assembly, protecting the hub bore from water ingress, debris accumulation and mechanical wear during continuous pool operation.

Function and role in the drive system

The wheel plug presses into the outer hub of each small rear wheel, covering the axle recess and maintaining the structural integrity of the wheel assembly. Without a correctly seated plug, the hub bore is left exposed, allowing pool water and fine grit to reach the bearing surfaces and accelerate wear on the wheel and axle components.

Compatible Dolphin models

This part is specified for the Maytronics Dolphin Ex 10 S1 platform. The white wheel plug is also common across several other Dolphin models that share the same S1 chassis architecture, including the Dolphin E10, Dolphin Active 10, Dolphin Proteus DX3, Dolphin Proteus DX4, Dolphin Proteus DX5i, Dolphin Echo and Dolphin Nautilus CC. Always cross-reference your robot’s parts diagram before ordering.

Symptoms that indicate replacement is needed

Replace this plug when you notice it is cracked, missing entirely, or has worked loose from the wheel hub. A missing or damaged plug can allow debris to pack into the hub recess, causing uneven wheel rotation, increased friction on the axle and, over time, premature failure of the small rear wheel itself.

Why genuine Maytronics parts matter

Genuine Maytronics parts are manufactured to original factory dimensions and materials, ensuring a precise press-fit into the wheel hub without play or misalignment. Counterfeit or generic alternatives may appear identical but often use inferior plastics that become brittle in chlorinated water, leading to early failure and potential damage to surrounding components. Fitting a genuine part safeguards your robot’s warranty and long-term performance.
