Maytronics Dolphin M4/M5 M400/M500 handle assembly grey and blue

This is the complete OEM handle assembly for the Dolphin Supreme M4, M5, M400 and M500 series robotic pool cleaners, finished in grey and blue. It mounts on top of the cleaner’s body and gives you a secure, two-handed grip to lift the robot cleanly out of the pool at the end of every cycle. Without an intact handle assembly, safely retrieving the unit from the water is awkward and risks dropping a heavy, water-filled robot on the pool coping.

What this handle assembly does in the Dolphin

The handle assembly spans the full width of the cleaner’s top shell and is designed to bear the full wet weight of the robot during retrieval. It incorporates a built-in float element that keeps the handle proud of the water surface when the cleaner is submerged, so you can locate and grip it without reaching into the pool. The grey body and blue accent components are moulded to the exact tolerances of the M4/M5 chassis, so the assembly clips into its retaining points under hand pressure without tools.

Which Dolphin models it fits

This handle assembly is confirmed for the Dolphin Supreme M4, Supreme M4 Pro, Supreme M5, Supreme M5 Pro, M5 Liberty, M400 and M500. All of these share the same top-shell platform and mounting geometry, making this a single cross-compatible part across the entire M4/M5 generation. If your unit is a Supreme or M-series variant not listed here, verify the top-shell part number before ordering.

Signs it needs replacing

The most common failure is a stress crack at either mounting lug — you’ll notice the handle flexes or rocks rather than sitting rigid on the shell. UV degradation and repeated pool-edge impacts can cause the grey body to become brittle, leading to a full snap under load. A broken float section means the handle sinks flush with the robot when submerged, making poolside retrieval genuinely hazardous. Replace the assembly as soon as you see visible cracking; do not wait for a complete break.

How to install it

Remove the old handle assembly by pressing the two retaining clips inward simultaneously and lifting upward — no tools required on most M4/M5 variants. Align the new assembly over the mounting slots on the top shell, press down evenly on both ends until both clips engage with an audible click, then tug upward firmly to confirm seating. The whole swap takes under five minutes and no disassembly of the cleaner body is needed.
