A spring cartridge filter panel helps capture debris in a compatible robotic cleaner using a spring-supported panel format, and this Maytronics Dolphin small version is supplied in a quantity of four using the 9991407-R4 reference. Cartridge panel sets are useful because replacing them together can help maintain balanced filtration across the full panel system.

This set has practical value because the spring-panel format is more specific than a general filter description and helps preserve the original cleaner filtration arrangement. A properly selected Maytronics replacement helps restore intended panel fit and contributes to more dependable debris capture.

This type of part is especially useful when existing filter panels are worn, damaged, or no longer holding debris effectively. That helps keep the cleaner filtering properly and reduces the need for piecemeal panel replacement later.

Installed in the proper application, these filter panels help support cleaner filtration and more dependable overall cleaning results.

  • Small spring cartridge filter panels for compatible Maytronics Dolphin cleaner applications
  • Supplied in a quantity of four
  • Helps capture debris during robotic cleaning cycles
  • Useful when replacing worn or damaged filter panels
  • Improves filtration consistency and maintenance confidence
