Pentair R111646 18″ Aluminum‑Back Stainless Steel Algae Brush

The Pentair R111646 heavy‑duty algae brush features a robust aluminum back and stainless steel bristles, designed for tackling tough algae and stains on plaster, concrete, and gunite pool surfaces.

Key Features:

  • 18″ wide head for fast coverage of large wall and floor areas
  • Durable aluminum back frame resists bending and corrosion
  • Stainless steel bristles provide aggressive scrubbing power on hard‑surface pools
  • Snap‑Adapt handle compatible with most telescopic poles for quick attachment

Technical Specifications:

  • Model / SKU: R111646
  • Brush Width: 18″
  • Suitable Surfaces: Plaster, concrete, gunite (not recommended for vinyl liners)
  • Frame Material: Aluminum back
  • Bristle Material: Stainless steel

Maintenance Tip: Use this brush monthly or whenever you spot algae growth. Always rinse after use, shake off debris, and store bristles downward to maintain shape. For best results, brush your pool while the pump is running to aid circulation of detached algae. Replace the brush if bristles become worn, bent or the frame loses integrity.
