Replacement fine filter basket for dolphin robotic pool cleaners designed to restore and maintain filtration performance. Key benefits Wide compatibility: compatible with dolphin robot pool cleaners including Active 10, E10, Echo, T15, Proteus dx3, Cayman, Escape, S50, CC, and Advantage. Not compatible with CC Pro. filtration: fine mesh captures hair, dust, diatoms, and other small debris to help keep pool water clear. Efficient debris handling: integrated bottom spring filter directs larger items such as leaves into the basket, improving filtration efficiency and simplifying debris removal. Durable construction: full ABS plastic frame supports the filter layer and resists breakage during normal use. Product details Function: replacement fine filter basket for use with compatible robotic pool cleaners to trap fine and coarse debris. Material: robust ABS plastic frame for steady support and long service life. Performance: designed for strong filtering capability that separates both fine particles and larger debris for easier maintenance. Use scenarios After a storm: collects leaves, twigs, and other large debris that enter the pool during windy weather. Homes with pets or heavy swimmer use: captures hair and fine particles before they settle or clog the circulation system. Routine pool maintenance: used as a replacement or spare filter basket to maintain cleaning performance of a compatible robotic cleaner. This filter basket is a direct, functional replacement part that focuses on filtration reliability and durability for supported robotic pool cleaner models.
