Ultrafine Filter Basket for Robotic Pool Cleaners (Compatible with Active 20 and PS) What it is A replacement ultrafine filter basket with ultrafine filter paper designed for robotic pool cleaners, compatible with Active 20 and PS models. Captures fine sand, leaves and other debris that traditional cloth filters miss. Why you need it Improved debris capture: The ultrafine filter paper traps smaller particles (sand, silt, fine leaves) so your pool stays clearer and your cleaner runs more efficiently. Protects the cleaner: By intercepting fine grit and debris, the filter reduces wear on internal components and helps maintain pump and brush performance. Low maintenance and reusable: Rinse with a garden hose to clear trapped dirt. Quick cleaning keeps the filter ready for repeated use and reduces replacement frequency. Key features Compatibility: Fits robotic pool cleaners including Active 20 and PS models without modification. Material and durability: Durable ABS plastic construction provides stability and resists breakage while maintaining consistent performance over time. Filtration performance: Ultrafine filter paper offers finer filtration than traditional cloth filters, improving debris reduction and overall pool cleanliness. Easy maintenance: Simple to remove and rinse clean with a garden hose for fast turnaround and continued reuse. Practical applications 1) Post-storm cleanup: Quickly remove sand and small organic debris tracked into the pool after windy conditions, restoring water clarity with minimal effort. 2) Regular weekly maintenance: Use as part of routine cleaning to capture fine particles before they settle, reducing the need for manual vacuuming and chemical adjustments. 3) Pools near trees or sandy areas: Ideal for pools that collect leaves, twigs and fine sand, preventing abrasive particles from circulating inside the robotic cleaner. What to expect Reliable fit for Active 20 and PS robotic cleaners. Noticeably reduced fine debris in pool water compared with standard cloth filters. Simple maintenance: hose off, reinstall, and continue cleaning. Materials and care Composition: ABS plastic basket with ultrafine filter paper. Cleaning: Rinse with a garden hose; allow to dry before long-term storage. Replace filter paper or basket if visibly damaged. Specifications retained from original Compatibility: Active 20 and PS robotic pool cleaner models. Construction: ABS plastic basket and ultrafine filter paper. Function: Captures sand, leaves and fine debris; reusable after rinsing. This replacement ultrafine filter basket provides finer filtration, robust construction and easy maintenance to keep your Active 20 or PS robotic pool cleaner operating cleanly and efficiently.
