Our 18-inch Leaf Canister connects between the pool vacuum hose and the vacuum itself to trap leaves and debris that can clog the pump basket or filter. The canister includes a large capacity polyester mesh bag and the lid pushes open for easy emptying without disconnecting vacuum hose. The leaf canister reduces the frequency of pump and filter maintenance. It attaches to suction type automatic pool cleaners. Use the award winning Leaf Canister for Pool Cleaners and save on pool maintenance!
