Maytronics 9991467-R4 Cartridge Filter Set - For Dolphin Active 20 30 40 60

What This Part Is Used For
This cartridge filter set installs inside compatible Dolphin Active 20, 30, 40, and 60 robotic pool cleaners. The cartridges capture debris and fine particles during operation. They are removed, rinsed, and reinstalled after cleaning cycles.

Why This Part Matters
Clogged or damaged cartridges reduce suction and limit cleaning performance. If filter media is torn or worn, fine debris may pass back into the pool. Replacing the cartridge set restores proper filtration and debris containment. Routine cartridge maintenance supports consistent cleaner efficiency.
