Description
This rough filter insert is a genuine Maytronics replacement component designed for compatible Dolphin robotic pool cleaners. The lightweight mesh insert fits inside the cleaner’s filter basket and acts as a pre-filter for larger debris before water passes through the finer filtration media.
