Swimming pool wall tile brush with 7-row rounded nylon head and reinforced aluminum backing — designed for efficient, durable, and gentle wall and tile cleaning. Key benefits Effective cleaning coverage: Seven rows of premium, rounded nylon bristles increase the cleaned surface area by up to 300% compared with single-row brushes, letting you remove grime and biofilm faster. Sturdy, long-lasting construction: Reinforced metal backing and premium aluminum structure add strength and resistance to bending or warping during heavy scrubbing. Tough on dirt, gentle on surfaces: High-density nylon bristles combined with a metal-backed head provide aggressive cleaning power in corners and grout lines while remaining safe for pool surfaces, including ethylene (vinyl) pools and hot tubs. Targeted corner and edge cleaning: The brush head profile and dense bristle pattern reach steps, corners, tile lines, and other hard-to-reach areas for a more thorough clean. Materials and performance Bristles: High-density nylon, rounded tips to reduce the risk of scratching while maintaining effective scrubbing action. Backing and reinforcement: Metal backing with premium aluminum reinforcement for enhanced structural strength and durability under pressure. Function: Designed specifically for wall and tile scrubbing in pools and hot tubs; balances aggressive dirt removal with surface protection. Practical uses and scenarios Routine pool maintenance: Remove algae and scum from wall tiles and waterline areas to keep the pool looking clean and reduce filter load. Hot tub and spa cleaning: Gently scrub interior surfaces and seams without scratching sensitive acrylic or vinyl finishes. Detail cleaning for corners and tile lines: Reach grout, step edges, and tight corners that standard brushes miss to keep surfaces sanitary and prevent buildup. What to expect Improved cleaning speed and coverage from the 7-row design. Durable performance thanks to metal backing and aluminum reinforcement. Safe use on common pool and spa surfaces, including ethylene (vinyl) pools. Note: This brush head is intended for manual scrubbing of pool walls, tiles, and hot tub surfaces.
