Bestway Flowclear Aqualite Pool Filter Cartridge Cleaning Tool - Removable Comb Head & Flow Control Knob - Ideal for In-Ground & Above Ground Pool Maintenance

I bought this to assist in the annoying task of cleaning my cartridge filter and my expectations were fairly low. I was pleasantly surprised by how effective this tool is -- gives great water pressure and the flow control knob is a nice feature. I used it with cartridge cleaning spray and got the best outcome I've had in probably a year on my filter. There were a number of fires in my area recently so there was a lot of fine soot in my filter that didn't want to come out with just a regular hose spray nozzle, but I saw significant improvement using this tool. Highly recommended for easier pool maintenance!
