Poolmaster 18 in Aluminum-Back Algae Brush - Heavy Duty Pool Cleaning

In this review the Poolmaster 18 in Aluminum-Back Algae Brush is examined for owners of inground gunite pools who need a durable tool to remove stubborn algae and stains. The single biggest reason to buy is its heavy-duty construction: a die-cast aluminum back and handle paired with five rows of stainless steel bristles that cut through embedded algae on hard pool surfaces better than a standard nylon brush. It is not for vinyl or fiberglass pools, and that limitation is important for the correct user.

Key Features

• Die-cast aluminum back and handle: provides extra-strength and resists bending during aggressive scrubbing for long-lasting use.
• Stainless steel bristles: designed to scrape away tough algae and mineral stains that softer bristles cannot remove.
• 18 in head width: covers a broader area than small brushes, making floor, wall and stair cleaning faster.
• Straight body design: offers a simple, familiar shape that is easy to maneuver on vertical walls and flat floors.
• Premier Collection quality: built from resilient components intended for repeated heavy-duty pool maintenance.

Who It's For

This brush is best for homeowners and maintenance crews with inground gunite or concrete pools that have a hard surface finish and recurring algae or stain issues. It suits users who need a robust tool for vertical wall scrubbing and larger surface coverage without frequent replacement.

It is not suitable for vinyl liners or fiberglass pools; anyone with those surfaces should look for a soft-bristle or specific vinyl-safe brush instead. Casual users with delicate pool finishes should avoid the abrasive stainless steel bristles to prevent surface damage.

Pros & Cons

Pros

• Durable die-cast aluminum construction resists bending and adds strength for heavy scrubbing.
• Stainless steel bristles effectively remove embedded algae and stains on concrete or gunite surfaces.
• Large 18 in head speeds up cleaning of floors, walls and stairs compared with smaller brushes.

Cons

• Not safe for vinyl or fiberglass surfaces and may be too abrasive for delicate finishes.
• Some users report mixed long-term bristle durability, so occasional bristle loss can occur under heavy use.
