Maytronics Dolphin Supreme M5 guide wheel - 3884997

Maytronics Dolphin Supreme M5 guide wheel

This is the genuine OEM guide wheel (part 3884997) for the Dolphin Supreme M5 robotic pool cleaner. It sits within the drive/track wheel system and keeps the rubber track belt correctly aligned and tensioned as the cleaner moves across the pool floor and walls. Without a serviceable guide wheel, the track slips, rides off-centre, or causes the cleaner to stall mid-cycle.

What this guide wheel does in the Dolphin

The guide wheel acts as a tensioning and alignment point for the drive track belt on each side of the chassis. It transfers rotational movement from the drive axle through the belt consistently, so the cleaner maintains straight, predictable travel patterns. A worn or cracked guide wheel introduces belt skip, which disrupts navigation and can accelerate belt wear on the opposing side.

Which Dolphin models it fits

The 3884997 base part number covers a wide range of Dolphin track-drive robots. Confirmed compatible models include the Supreme M4, Supreme M5, M400, M500, Nautilus, Triton Plus, Apollo Plus, Edge, DX6, Deluxe 4, Deluxe 5, 3001, 2×2, and Wave 90, among others. Always verify your exact model variant before ordering — the Supreme M5 is the parent product listed for this SKU.

Signs it needs replacing

The track belt derails repeatedly even after reseating. You’ll notice the cleaner pulling consistently to one side, or the belt showing uneven wear on its inner edge — both are direct consequences of a collapsed or cracked guide wheel. Inspect the wheel for flat spots, radial cracks, or visible deformation; any of these means replacement is overdue.

How to install it

Remove the track belt on the affected side by hand — no tools needed to free the belt itself. The guide wheel unclips or slides off its axle peg depending on the chassis revision; reseat the new wheel, confirm it spins freely with no side play, then refit the track belt. The whole swap takes roughly 10–15 minutes per side and requires no special equipment.
