Clean filter cartridges are essential for keeping a robotic cleaner moving water efficiently and capturing fine debris. This Hayward TigerShark cartridge and frame set includes two replacement filter assemblies for compatible cleaner models, making it easier to refresh filtration performance after heavy use. Over time, cartridges can clog, deform, or become difficult to clean thoroughly. Replacing the filter assemblies helps the cleaner maintain suction, debris capture, and proper water flow through the unit. Keeping an extra set on hand also allows one pair to dry while another is in service, which is helpful for busy pools. Set of two cartridge filter assemblies with frames Designed for compatible Hayward TigerShark robotic cleaners Helps restore debris capture and water flow Ideal for routine cleaner maintenance or seasonal replacement Part RCX70100 for accurate service matching
