The Intex 10" Wall Brush is a vital "manual" tool for "adult" pool owners dedicated to maintaining a hygienic and sparkling swimming environment. Specifically engineered to scrub away algae buildup and calcium deposits, this brush ensures your pool liner remains in top condition with minimal effort.

Key Features:

• Contoured Curved Design: The unique 10-inch ($25$ cm) curved shape is specifically designed to "manually" clean deep into corners and along rounded steps where debris often hides.

• Heavy-Duty Bristles: Features high-density, stiff bristles that provide the "manual" scrubbing power needed to lift stubborn spots without damaging your pool liner.

• Standard Pole Compatibility: Designed to "manually" snap onto any standard telescoping aluminum pole ($29.8\text{mm}$ inner diameter) for extended reach across deep pools.

• Lightweight Efficiency: With a net weight of approximately 0.117kg, this brush allows for a lightweight "manual" grip, reducing arm fatigue during long cleaning sessions.
