Maytronics Dolphin Active X4 IOT CB

Maytronics Dolphin Active X4 IOT CB exploded view & spare parts

The Maytronics Dolphin Active X4 IOT CB is a feature-rich robotic pool cleaner built for thorough floor-to-waterline cleaning, complete with Wi-Fi connectivity via the MyDolphin™ Plus app for smart scheduling and remote control. Like every pool robot, it relies on a set of precision-engineered components that endure continuous submersion, abrasion, and mechanical stress. This exploded-view diagram page lists every numbered part for the Active X4 IOT CB so you can pinpoint exactly what you need, browse the matching genuine Maytronics spare part on poolparthub.com, and get your robot back in the water without guesswork.

How to use the exploded-view diagram to find your part

The diagram above breaks the Dolphin Active X4 IOT CB down into its individual components, each assigned a unique reference number. Start by identifying the area of the robot that needs attention — drive section, filtration bay, motor housing, or electrical system — then locate the corresponding numbered callout in the diagram. Match that number to the part list below the diagram, note the official Maytronics part number, and use it to search or add the item directly to your cart. This method removes any ambiguity about fitment: the Active X4 IOT CB uses specific part revisions that are not always interchangeable with earlier Active series models, so always cross-reference the diagram rather than ordering by description alone.

Main replaceable parts on the Active X4 IOT CB

The Dolphin Active X4 IOT CB is built around a core set of serviceable assemblies. The rubber or PVC tracks drive the robot across pool surfaces and are the first parts to show visible wear. The brushes — typically a combination of rubber and PVC bristle rollers — scrub the floor, walls, and waterline and work in tandem with the tracks. Inside the filtration bay you’ll find interchangeable filter panels or filter bags that trap fine and coarse debris; both formats are available so you can match filtration grade to your pool’s conditions. The impeller sits inside the pump housing and generates the suction that draws water through the filter, while the motor unit (drive motor or pump motor assembly) powers the robot’s movement and water flow. Connecting the robot to the power supply is the swivel floating cable, which prevents tangling during operation. The power supply unit (PSU) transforms mains voltage to safe low-voltage DC and, on the IOT CB variant, includes the Wi-Fi module that enables app connectivity. Finally, the handle lets you lift the robot cleanly from the pool, and the matching caddy (trolley) stores and transports both the robot and its cable between uses.

Common wear items and when to replace them

Tracks and brushes are the highest-wear components on the Active X4 IOT CB because they are in constant contact with abrasive pool surfaces. Inspect the tracks each season for cracking, stretching, or missing lugs; a track that slips or causes the robot to veer to one side needs immediate replacement. Brushes lose bristle stiffness over time — if the robot is leaving visible debris lines or struggling to climb walls, worn brushes are the most likely cause. Filter panels and bags should be rinsed after every cleaning cycle and replaced once they show tears, deformation, or permanent clogging that reduces suction noticeably. The impeller is prone to jamming from hair, leaves, and fine grit; if suction drops suddenly, check and clear the impeller before assuming motor failure. The floating cable can develop kinks, cracks in the outer sheath, or internal wire breaks — any visible damage to the cable jacket is a safety reason to replace it promptly. The power supply should be kept dry and away from pool water at all times; if the robot fails to start or the app loses connection, testing or replacing the PSU is the logical first step.

Why genuine Maytronics parts matter for your Active X4 IOT CB

The Dolphin Active X4 IOT CB is designed as an integrated system: track tension, brush roller diameter, impeller clearances, and motor current draw are all calibrated to work together within tight tolerances. Genuine Maytronics spare parts are manufactured to the same specifications as the original components, which means they restore the robot’s performance, energy efficiency, and safety characteristics precisely. Third-party alternatives may appear to fit but can introduce subtle mismatches — an impeller with slightly different blade pitch, for example, can overload the motor and shorten its life. Using genuine parts also protects any remaining warranty coverage on your unit. Every part listed on this page is an authentic Maytronics component, supplied to poolparthub.com through official distribution channels, so you can order with confidence that what arrives is the correct part for your specific robot.

Storing and caring for your Active X4 IOT CB between seasons

A little end-of-season maintenance goes a long way towards extending component life. After the final cleaning cycle, remove and rinse the filter panels or bags thoroughly and allow them to dry before storage — damp filters stored for months can degrade the filter medium and promote mould. Wind the floating cable loosely around the caddy without tight kinks to prevent internal wire stress. Store the power supply indoors in a dry location, away from frost, and disconnect it from the mains. Before the first run of a new season, inspect the tracks and brushes visually, confirm the impeller spins freely by hand (with the power supply disconnected), and test the Wi-Fi pairing via the MyDolphin™ Plus app. Catching wear early means ordering a single inexpensive part rather than a more costly repair later in the swimming season.
