Purpose: Ultrafine replacement filter plates designed to restore and maintain the filtration performance of compatible robotic pool cleaners by capturing fine dirt, leaves and sediment that reduce cleaning efficiency. Compatibility: Directly compatible with For20, For30 and forM600 robotic pool cleaner models. Fits into the existing filter basket for a straightforward upgrade without additional parts. Easy maintenance: Rinse away trapped debris with a standard garden hose — no tools or special cleaners required. Quick rinsing keeps filters ready for the next cleaning cycle and reduces downtime. Simple installation: Each filter plate is clearly numbered to match positions in the basket, so anyone can install replacements correctly and quickly, even without prior experience. Performance benefits: Ultrafine filtration helps the robot maintain suction and cleaning consistency by preventing clogging from small particles. Regular replacement keeps your cleaner operating closer to original performance levels. Practical attributes: Designed as drop-in replacement plates for the specified models; engineered to work with the robot’s existing filter basket layout and cleaning cycle. Durable construction for repeated rinse-and-reuse maintenance. Typical use scenarios 1) Routine seasonal maintenance: Replace worn filter plates before peak swimming season to ensure consistent, thorough cleaning. 2) After storms or heavy yard debris: Swap in fresh plates to remove extra leaves, pollen and sediment that can overwhelm a clogged filter. 3) Rental or multi-user pools: Keep spare numbered plates on hand to perform fast filter changes between users and maintain reliable cleaning performance. What you get: A set of ultrafine replacement filter plates sized and numbered to drop into the filter basket of For20, For30 and forM600 robots, enabling fast installation and simple hose cleaning for ongoing pool care.
