The Combination DuoBrush cleaner is an 18-inch wide brush with a fan of stainless and nylon bristles measuring more than 4 inches from front to back. The brush features an ergonomic design to help reduce backache by using an angled handle that allows a natural, relaxed, upright position when brushing the pool. It’s made to clean both plaster and gunite pools. Contact: 800.753.1233;
