Key benefits Deep, faster cleaning: Seven rows of premium nylon stiff hair increase cleansing efficiency by up to 300%, covering more surface with each pass to reduce time spent scrubbing. Thorough reach: Rounded, hemispherical brush side and smooth edges allow the brush head to access corners, steps and curved surfaces for a complete clean. Built to last: Reinforced aluminum backing resists corrosion and adds stability for heavy-duty scrubbing, extending the brush head’s service life even with frequent use. Surface-safe action: Smooth rounded sides combined with soft nylon stiff hair clean effectively without scratching pool liners, painted floors, or other delicate materials (safe for ethylene and similar surfaces). Features Bristle arrangement: 7 rows of high-density nylon stiff hair for strong scrubbing power against stubborn dirt, algae and grime. Construction: Sturdy metal backing with a corrosion-resistant aluminum layer for support and durability during rigorous cleaning. Design: Hemispherical brush side and rounded edges for edge-to-edge contact on walls, tiles and steps. Compatibility: Suitable for all types of pools and surfaces including tile, painted floors, vinyl/ethylene liners and concrete. Performance and use Effective on walls and tiles: The dense, stiff nylon bristles and metal backing deliver the force needed to loosen scale and algae on vertical surfaces and grout lines. Gentle on liners and painted finishes: Rounded sides and carefully chosen bristle density help prevent scratching while still removing deposits. Long-lasting under frequent use: Reinforced aluminum backing withstands repeated scrubbing and resists corrosion from pool chemicals. Practical applications Weekly maintenance: Quickly remove light algae and film from walls and steps before vacuuming or filtering to keep water clear and surfaces healthy. Deep cleaning before seasonal opening or closing: Use the stiff nylon rows to tackle stubborn grime on tile and concrete coping during intense cleaning sessions. Sensitive-surface care: Clean vinyl or painted pool areas where a gentle touch is required, relying on the rounded design to avoid damage.
