Maytronics Dolphin Cartridge Filter Kit

The Maytronics 9991428-ASSY is the Dolphin cartridge filter kit, the genuine replacement filter assembly for several of the most common Dolphin robotic cleaners.

Which cleaners

It fits the Dolphin M200, M400, Sigma, Nautilus CC Plus and Nautilus CC Supreme. If your cleaner is one of those and its cartridge filter is torn, clogged past cleaning or missing, this kit restores it.

The cartridge filter locking hook is a separate part, so check yours before ordering. If you would rather run a bag than cartridges, Maytronics offers a filter bag conversion kit as an alternative to this one.
