Maytronics 9991408-R4 Spring Cartridge Filter - Large

What This Part Is Used For
This large spring cartridge filter installs inside compatible Maytronics robotic pool cleaners. It forms part of the internal filtration system that captures debris during automated cleaning cycles. The panel is removable for rinsing and routine maintenance.

Why This Part Matters
Worn or clogged filter panels reduce suction and limit cleaning performance. Damaged filter media allows debris to reenter the pool. Replacing the large spring cartridge restores proper debris retention and internal flow. Routine filter maintenance supports consistent robotic operation.
