Pro-Series Arched Wall Brush, measuring 20”/50cm, made with 7 rows of durable nylon bristles. Used for pool wall cleaning. Maintaining your pool can be a tedious job, but it’s an important part of keeping your pool sparkling clean and safe for years of enjoyment. Clean the walls and floor. Use cleaners, brushes and vacuums recommended by the pool manufacturer. Start at the shallow end and continue to the deep end. Overlap each stroke when vacuuming and brushing to cover all areas thoroughly. Always keep the vacuum head under water while in use. To speed up the process, dedicate 10 minutes a day to brushing down the walls.
