Pool brushes

Liner or PVC finishes require brushes with flexible nylon or polypropylene bristles only. Metal bristles can cause microperforations and irreversible scratches in the vinyl liner. For this type of finish, a plastic body with rounded edges is recommended to prevent accidental scuffing at corners and joints during intensive scrubbing.

To eliminate black algae and stubborn limescale deposits on glass à carrelage or painted concrete, the most effective option is a brush with stainless steel bristles. By concentrating the effort over a compact width, the operator can apply enough mechanical pressure to penetrate the rough grout surface. We recommend using a straight brush with metal bristles, designed with corrosion-resistant alloy filaments that remove the biofilm without shedding during heavy-duty work.

Almost all commercial pool-cleaning heads use a standard female connection with an inner diameter of 28 mm to 30 mm. To check whether your current equipment is compatible, simply check the fastening method:

• Butterfly-style clip system (EZ clip): uses internal plastic pins that snap into the two side holes in the telescopic tube.
• Wing-nut fastening: uses through-bolts and threaded plastic nuts for a firm grip under high lateral forces.

Both mechanisms are interchangeable with conventional aluminum telescopic poles approved for pool maintenance.

A 25 cm straight brush is ideal for hard-to-reach areas, steps, and the cove where a wide head loses contact. Linear models concentrate the force of your arm over a smaller area, improving the removal of dirt where the slope changes. To keep the flat floor clean during routine sessions, you can alternate this task with a manual pool vacuum with brushes, a tool that vacuums up suspended debris while loosening settled particles.

The key difference lies in the degree of mechanical abrasion and compatibility with the pool's interior lining:

• Nylon or synthetic polymer bristles: flexible and chemically resistant to chlorine. Suitable for polyester, fiberglass, acrylic paint, and pool liners.
• Stainless steel bristles: extremely rigid, they are designed to remove calcified biological and salt deposits. Their use is limited to mortar, gunite, or glass mosaic made of à carrelage.

Choosing the wrong material can scratch the gelcoat or tear the vinyl, so never use metal bristles on heat-welded materials.

Excessive friction along the waterline is usually caused by using a head with bristles that are too stiff or rigid plastic that comes into direct contact with the edges. On acrylic surfaces or decorative liners, use a dense cellulose sponge combined with a pool degreaser, reserving brushes exclusively for underwater walls. For deposits on the flat bottom where fine dirt needs to be removed without damaging the surface, it is advisable to attach a professional vacuum head with perimeter wheels that keep the aluminum body from making direct abrasive contact.

The operational lifespan of a brush is usually between two and three swimming seasons, depending on sun exposure and the concentration of chemicals. Replace the accessory immediately when the bristles lose more than 20% of their original density, remain permanently flattened to the sides, or the plastic frame develops a whitish, crystallized appearance due to ultraviolet radiation. Keeping a degraded head reduces mechanical performance by half and requires you to spend more on shock sanitizers to make up for the lack of friction.
