Maytronics 9991412-R1 Cartridge Filter Assembly With Bottom Lid

What This Part Is Used For
This cartridge filter assembly with bottom lid installs inside compatible Maytronics robotic pool cleaners. It serves as the internal debris filtration module and lower housing interface during cleaning cycles. The assembly captures dirt and suspended particles while maintaining proper internal flow.

Why This Part Matters
A cracked bottom lid or worn filter assembly can reduce suction and allow debris to bypass the filtration area. Poor internal sealing impacts cleaning efficiency and debris containment. Replacing the full assembly restores proper fit and filtration performance. Timely replacement prevents repeat service calls and performance complaints.
