Maytronics 9991428-assy Dolphin Cartridge Filter Kit

Product Description

The MAYTRONICS 9991428-assy Dolphin Cartridge Filter Kit is a replacement filtration assembly designed for Dolphin-brand robotic pool cleaners. This kit provides the cartridge filter components needed to restore proper water filtration performance in compatible Dolphin units. The cartridge-style filter captures fine debris, algae, and particulate matter as the robotic cleaner cycles through the pool. Pool service technicians and knowledgeable owners install this kit during routine maintenance or when filter media becomes worn, clogged, or damaged beyond cleaning.

This filter kit is suited for residential robotic pool cleaner applications. It is a direct replacement intended to maintain the filtration efficiency of supported Dolphin robotic cleaner models during scheduled service intervals or unplanned filter replacement needs. Having the correct cartridge filter assembly installed ensures the cleaner maintains proper flow and debris collection throughout the cleaning cycle.
