ABSTRACT:
A pool filter cleaning device (1) which allows a person to thoroughly clean a filter cartridge (15) quickly and easily with minimal amount of splash back. The pool filter cleaning device (1) is comprised of a handle (2), an angled head section (12), a shield (6) and a nozzle (8). The device (1) is attachable to standard garden hoses (3) and utilizes water pressure to clean the cartridge filter (15). The handle (2) is attached to an angled head section (12) having a preferably transparent shield (6) attached therebetween. The head section (12) is angled so as to provide a more comfortable cleaning position for a user. The shield (6) has a duel purpose as it separates the pleats (16) on the cartridge filter (15) and prevents water and debris from splashing back onto the user.
