How do new fine filter panels improve cleaning performance?

Replacing clogged or damaged fine filter panels restores the unit’s ability to trap small particles and maintain proper water flow. Fresh panels reduce strain on the robot’s pump and motor, helping it run more efficiently and complete cleaning cycles as intended. This simple maintenance step often delivers noticeable improvements in clarity and debris pickup.

• Removes fine dirt, pollen, and silt that coarse filters miss
• Restores optimal water flow and suction efficiency
• Reduces wear on pump components by preventing blockages
• Helps the cleaner finish cycles in the expected time

What makes these replacement panels a genuine Dolphin part?

These panels are Maytronics-certified parts produced to the manufacturer’s standards, so dimensions, material quality, and filtration rating match the originals. Using genuine parts helps ensure the best fit and function compared with generic aftermarket alternatives. Certification also supports warranty and service expectations for many owners.

How easy is it to replace the fine filter panels?

Swapping these panels is typically a quick, tool-free task that most pool owners can perform in minutes. Remove the cleaner’s top cover or filter cassette per the user manual, slide out the old panels, and insert the new ones. Rinse the parts before installation if instructed, and confirm the panels sit snugly to prevent bypass of unfiltered water.

• Usually no tools required—follow the robot’s manual
• Quick pull-and-replace procedure for most models
• Rinse new panels if recommended before first use
• Inspect seals and cassette for wear while replacing panels
