The answer
What to know.
The Dolphin EON 120d uses an ultra-fine, 14-micron DebrisLock™ filter basket. Its lid helps trap more debris while allowing filtration from all directions.
The basket’s 4-liter capacity lets it collect more debris during each cleaning cycle. Its closed chamber helps keep captured dirt and debris from returning to the pool water, supporting better cleaning performance.
The basket also has a built-in filter backwash system. An additional 1-liter backwash compressed container helps keep debris locked inside the filter.
Backwashing runs automatically at the end of the cleaning cycle and when the filter is full to help improve overall performance.
