Maytronics Dolphin M400 IOT EU

Maytronics Dolphin M400 IOT EU exploded view & spare parts

This page provides the full exploded-view diagram and complete spare parts catalogue for the Maytronics Dolphin M400 IOT EU robotic pool cleaner. The M400 IOT EU is a premium, always-connected robot that cleans floors, walls and the waterline in a single 2.5-hour cycle, guided by CleverClean™ smart-navigation technology and controlled remotely via the MyDolphin™ Plus app. Every numbered component shown in the diagram below is available as a genuine Maytronics spare part, so you can keep your robot running at peak performance season after season without replacing the entire unit.

The diagram on this page breaks the Dolphin M400 IOT EU down into every individual sub-assembly and component, each assigned a unique reference number. To find the part you need, locate the component on the diagram — whether it is a drive track, a brush roller or an internal motor assembly — note its reference number, and use that number to search or browse the listings below. Each listing includes the official Maytronics part number, a description, and compatibility confirmation for the M400 IOT EU (product code 99991049-EUI). If you are unsure which part has failed, cross-reference the diagram with the symptoms you are seeing: a robot that veers to one side almost always points to a worn track or drive unit, while reduced suction typically signals a clogged filter panel or a worn impeller.

Main replaceable parts on the Dolphin M400 IOT EU

The M400 IOT EU is built around a dual-drive motor system that delivers precise 360° manoeuvrability regardless of pool shape, slope or obstacles. The key serviceable assemblies include: rubber drive tracks that grip every pool surface; a set of three brush rollers (one active power brush plus two scrubbing brushes) that loosen and lift dirt, debris and algae from the floor, walls and waterline; top-load wkłady filtracyjne / worki filtracyjne available in fine and ultra-fine grades to capture everything from large debris down to microscopic particles; the wirnik that drives water through the filtration circuit; the jednostka motoryczna (drive and pump motors); the anti-tangle swivel kabel pływający; obsługujący Wi-Fi IoT zasilacz that connects the robot to the MyDolphin™ Plus app; the top uchwyt for lifting the robot out of the water; and the wheeled caddy for storage and transport between cleaning sessions.

Typowe elementy podlegające zużyciu i terminy ich wymiany

Like any robotic pool cleaner used regularly throughout the swimming season, the M400 IOT EU has several parts that wear predictably. Drive tracks should be inspected each spring for cracks, stretched links or reduced grip — a robot that slips on walls or moves sluggishly is a strong sign the tracks need replacing. Brush rollers lose their bristle depth over time; once the brushes no longer make firm contact with the pool surface, scrubbing efficiency drops noticeably and algae can take hold between cleans. As a general guide, brushes often need attention after two to three seasons of regular use. Wkłady filtracyjne i worki should be rinsed after every cleaning cycle and replaced when the filter media becomes discoloured, torn or permanently clogged — compromised filtration puts extra strain on the impeller and motor. The kabel pływający, which must flex thousands of times per season, can develop micro-cracks in the outer jacket or internal wiring faults; inspect it for kinks, exposed wire or swivel stiffness annually. The zasilacz should be stored indoors and away from direct sunlight when not in use, and its LED indicators can help you diagnose connection or cycle faults early.

Dlaczego oryginalne części zamienne Maytronics mają znaczenie

Maytronics engineers each Dolphin component to work as part of a precisely balanced system. Genuine Maytronics tracks, for example, are moulded from a specific rubber compound chosen to grip tiled, pebble and vinyl surfaces without damaging them, while third-party alternatives may use different hardness ratings that accelerate wear on both the track and the pool shell. Genuine filter cartridges are rated to the same fine and ultra-fine particle specifications that the M400’s impeller and motor were designed around, meaning the pump does not have to work harder than intended. Using genuine parts also keeps your warranty valid and ensures that the robot’s CleverClean™ navigation — which relies on consistent torque from the drive motors and unobstructed water flow through the impeller — behaves exactly as Maytronics intended. All parts listed on this page are sourced directly from Maytronics and are confirmed compatible with the Dolphin M400 IOT EU.
