Product details

This is a set of four replacement filter cartridge elements for Dolphin robotic pool cleaners, Maytronics part 9991425. They are the standard cartridges, made to catch fine debris such as sand and silt along with the usual leaf and grit load.

Which cleaners take them

The set fits the Dolphin Nautilus, Triton, Wave 75, Edge, Quest and Premier, and it also serves the Pentair Prowler 820 and Prowler 830.

When to change them

Cartridges do not last forever. Once the media is packed with fine silt that will not rinse out, or a panel splits, the cleaner pulls harder for less flow, climbs poorly and leaves dirt in the pool. Owners often blame the motor when the filter is the problem. A fresh set of four is the cheapest thing to try first.

A finer option

Maytronics also makes an ultra fine version of this cartridge set for pools that carry very fine dust. It is a separate part number.
