Maytronics Dolphin Active 4/5 Außengehäuse-Baugruppe – 99952090-ASSY

Maytronics Dolphin Active 4/5 outer casing assembly

This is the genuine Maytronics replacement outer casing assembly for the Dolphin Active 4 and Active 5 robotic pool cleaners, including the Dolphin Active Classic CB. Supplied as a complete pre-assembled unit, it forms the full structural shell of the robot — enclosing the internal drive, motor and filtration components and defining the robot’s overall profile in the water.

Funktion und Rolle im Roboter

The outer casing is the primary structural housing of the Dolphin Active 4/5. It protects the internal electronics, motor units and filter basket bay from the pool environment, and provides the mounting points for the side panels, brush assembly and track system. A structurally sound casing is essential for maintaining correct water-flow dynamics through the robot and ensuring all serviceable sub-assemblies remain properly seated and sealed during operation.

Kompatible Modelle

This casing assembly is designed specifically for the Dolphin Active 4 and Active 5 platforms, which include the Dolphin Active Classic CB sold across Europe. It is not interchangeable with the Active 3/SX3 casing (99952115-ASSY), the Comfort Active/C3 casing (99952091-ASSY) or other Active-series variants — always verify your model before ordering.

Signs that the outer casing needs replacing

Visible cracks, fractures or warping in the robot’s shell are the clearest indicators. Secondary symptoms include tracks or side panels that no longer clip or sit flush, water ingress into the electronics bay, abnormal noise caused by loose internal components, or the robot failing to maintain a consistent seal around the filter cover. A damaged casing will accelerate wear on every sub-assembly it houses.

Warum Originalteile von Maytronics so wichtig sind

Aftermarket casings are frequently moulded to incorrect tolerances, causing misalignment of the brush shaft, track rollers and filter bay lid — faults that are difficult to diagnose and that void the Maytronics warranty. This genuine assembly is manufactured to the original specification, ensuring every mounting point, clip boss and drainage aperture matches the design intent precisely. It is supplied as a complete ASSY unit, ready to fit without additional fabrication.
