Dolphin Supreme M3: the M-Line ancestor
The Dolphin Supreme M3 was an earlier generation of Maytronics' premium M-Line — the family that today runs from the M200 to the M700. The M3 is discontinued, but well-kept units still clean pools daily, and "dolphin m3" remains a searched model among owners and second-hand buyers.
Keeping an M3 alive
Filters, brushes and tracks follow standard Dolphin service patterns (parts guide) — buy spares when you see them, as discontinued-model stock only shrinks. Faults follow the classic patterns too: our troubleshooting guide, starts-then-stops fix and reset procedure all apply. Sealed motor-unit failures usually mark the economic end.
What replaces it
Its direct descendants: the M400 and M600 carry the M-Line torch with app control and current warranties (see M500 vs M700 for the top of the range). US buyers get equivalent duty from the Nautilus CC Supreme.
