Maytronics Dolphin E20 wheel cap grey S1 - M96100024

Maytronics Dolphin E20 wheel cap grey S1

This is the genuine Maytronics grey wheel cap (tapón rueda) for the S1 platform Dolphin E20 robotic pool cleaner. It is the small protective cover that snaps over the axle end of the drive wheel, retaining the wheel on its shaft and shielding the axle stub from abrasion, pool chemicals and debris ingress during operation.

Function and design

The wheel cap serves as the outer retention plug for the drive wheel assembly on the S1 chassis. By securing the wheel firmly on its axle, it prevents lateral play that would cause uneven track loading, erratic steering or accelerated wear on the drive components. The grey colour matches the standard S1 bodywork of the Dolphin E20 range.

Compatible Dolphin models

This part is designed for Dolphin robots built on the S1 platform. The primary confirmed fitment is the Dolphin E20 (model reference 99996148). Given the shared S1 chassis architecture across the E-series entry range, always verify against your specific model number before ordering, as S1 parts can span multiple entry-level Dolphin variants.

Symptoms that indicate replacement is needed

Replace this cap if it is cracked, chipped or missing entirely. A damaged or absent wheel cap allows the wheel to drift sideways on its axle, which can cause the robot to veer off course, generate clicking or grinding noises from the wheel bay, and accelerate wear on the axle shaft itself. Early replacement prevents secondary damage to more costly drivetrain components.

Why genuine Maytronics matters

Aftermarket wheel caps are often moulded from inferior plastics that become brittle under prolonged UV and chlorine exposure, leading to premature fracture. A genuine Maytronics part is manufactured to the precise snap-fit tolerances of the S1 wheel hub, ensuring secure retention without wobble and maintaining the factory-intended drive geometry of your Dolphin E20.
