AGIZIO Swimming Pool Filter Cartridge Cleaner - Heavy Duty Spa & Pool Filter Cleaning Tool for Removing Debris, Dirt & Algae - Ideal for Inground & Above Ground Pools, Hot Tubs & Water Filtration Systems

This cartridge filter tool does exactly what every pool owner wants. The tool separates the fiberglass pleats for fast and thorough cleaning with the high pressure streams created by the fingers of the tool. After cleaning 4 large filters in about 15 minutes I am impressed.(Being made of plastic is the only possible negative I can anticipate. I was very careful not to put too much pressure on the connection between the tool and the garden hose just in case. I would recommend having a helper hold each filter steady while you use one hand to move the tool and the other on the hose near the connection to both work the tool and prevent adverse pressure at the connection for longevity of the tool.)All that being said I think it worked perfectly!
