Best Pool Brushes
The best pool brush for most people is a standard 18-inch nylon-bristle brush with a curved aluminum back, because nylon bristles are safe on every pool surface and 18 inches covers a wall in a manageable stroke. The single decision that actually matters is bristle material, and it is a safety decision, not a preference: nylon bristles work on vinyl, fiberglass, concrete, plaster, and tile, while stainless-steel bristles clean tough algae off unpainted concrete and plaster but will permanently scratch a vinyl liner or fiberglass gelcoat. Get that one thing right and almost any well-built brush will do the job. Brushing is not busywork either; it lifts dirt and breaks up the biofilm that algae hides under so your sanitizer can actually reach it, which is why it is step one in getting rid of pool algae. Here are the picks, sorted by the job you need done.

Poolmaster 18-Inch Premier Nylon-Bristle Pool Brush
Who it is for: Almost every pool. Weekly brushing on vinyl, fiberglass, concrete, plaster, or tile.
- +Nylon bristles are safe on every pool surface, so you never have to think about scratching a liner or gelcoat.
- +The 18-inch head is the sweet spot: wide enough to cover a wall quickly, narrow enough to press the bristles flat against the surface with even pressure.
- +The curved aluminum back and end bristles reach into the cove where the wall meets the floor, the spot a flat brush skips.
Watch out: Most brushes do not include the telescoping pole. Confirm the head uses a standard spring-clip pole fitting so it snaps onto a pole you already own or a cheap universal one.
Wall Whale Classic Weighted Pool Brush
Who it is for: Large pools and deep ends where a normal brush head floats up off the floor and fights you.
- +A weighted head stays pressed down on the pool floor instead of floating up, so you can actually scrub the deep-end floor without leaning your whole body into the pole.
- +The wide 18-inch nylon head is safe on any surface and clears a lot of floor per pass, which matters on a big pool.
- +The design lets you push and pull with far less arm strain, so brushing a large pool stops being the chore you skip.
Watch out: It is a floor and lower-wall brush by design. You still want a lighter standard brush for waterline tile and the upper walls where a heavy head is overkill.
U.S. Pool Supply 18-Inch Stainless Steel Algae Pool Brush
Who it is for: Unpainted concrete, gunite, and plaster pools fighting stubborn spots of black or mustard algae.
- +Stiff stainless-steel bristles bite into the rough surface of plaster and gunite and break the waxy protective cap on black algae so chlorine can finally kill it.
- +It cuts through the ground-in mustard and green algae in dead spots that a soft nylon brush just slides over.
- +Built as a dedicated problem-solver, not an everyday brush, so it is stiff where you need stiffness.
Watch out: Never use stainless-steel bristles on a vinyl liner or a fiberglass pool. The metal will gouge the liner and scratch the gelcoat permanently. On those surfaces use a stiff nylon algae brush instead.
Poolmaster Corner and Step Pool Brush
Who it is for: Reaching the steps, ladder area, swim-out, and rounded corners a flat 18-inch head cannot sit flat against.
- +A rounded or angled nylon head follows the curve of steps and corners, the low-circulation dead spots where algae starts first.
- +Small and maneuverable, so it gets behind ladders and into the tight geometry a full-size brush bridges right over.
- +Nylon bristles keep it safe on the molded steps and swim-outs found on vinyl and fiberglass pools.
Watch out: This is a detail brush, not a replacement for a full-size brush. Pair it with the 18-inch overall pick for the open walls and floor.
What actually matters when buying
Match the bristles to your pool surface, this is the one rule. Nylon bristles are the safe default and work on every surface: vinyl, fiberglass, concrete, plaster, and tile. Stainless-steel bristles clean tough algae and stains off unpainted concrete, gunite, and plaster, but they will permanently scratch a vinyl liner or a fiberglass gelcoat, so never put metal bristles on those surfaces. If you have any doubt about your surface, buy nylon. A stainless brush is a targeted tool for a hard-surface pool with an algae problem, not an everyday brush.
18 inches is right for most, 24 for big pools. An 18-inch head is the standard for a reason: it covers a wall in a reasonable stroke while still letting you press the bristles flat with even pressure. A 24-inch brush like a big-sweep model clears more floor per pass on a large pool, but it is harder to keep flat against a curved wall and it takes more arm strength. Look for a curved back and end bristles so the brush can reach the cove where the wall meets the floor.
A weighted brush is worth it for deep ends. The most annoying part of brushing a deep end is the head floating up off the floor while you push down on the pole. A weighted brush stays planted on the floor so you scrub instead of wrestle. If your pool is small and shallow it is unnecessary, but on a large in-ground pool with an 8-foot deep end it turns brushing from a fight into a chore you will actually do every week.
Buy a decent pole, and check the fitting. Almost no brush includes the telescoping pole, and the pole matters more than people expect. A flimsy pole flexes and springs when you push, which wastes your effort and pops the brush off the wall. Most heads use a standard spring-clip fitting that takes a universal pole, so confirm the fitting matches, then spend a little on a rigid aluminum pole. The same pole runs your skimmer net and vacuum head, so it is a shared upgrade.
Brush the dead spots weekly, more when algae hits. Brush at least once a week, and aim at the low-circulation dead spots first: steps, behind ladders, corners, the swim-out, and the deep-end floor, where the water barely moves and algae takes hold. When you are actively fighting algae, brush daily, because breaking up the film is what lets chlorine reach and kill it. Brushing moves debris toward the drains and skimmer, but it does not remove it, so follow up with a pool vacuum or robotic cleaner. A brush also cannot fix water balance; keep your free chlorine in range with the chlorine calculator.
How we picked
This is a research-based guide that compares pool brushes on the one factor that changes the buy, bristle material versus pool surface, plus head size, back and end design, and pole fitting, weighed against a broad set of owner reviews across the established brands. We do not bench-test products, and we take no payment for placement. The surface-safety guidance reflects well-documented manufacturer practice, and a commission never changes a pick. Match the brush to your pool surface and follow the product label.

Frequently asked questions
What is the best type of brush for a pool?
For most pools, an 18-inch nylon-bristle brush with a curved back is the best type, because nylon is safe on every surface and the size is easy to control. The only time you want a different type is a hard-surface pool (unpainted concrete, gunite, or plaster) with stubborn algae, where a stiff stainless-steel-bristle brush cuts through the film that nylon slides over. Never use stainless bristles on a vinyl liner or fiberglass pool; they scratch permanently. So the rule is nylon by default, stainless only for algae on a hard surface.
What is the best pool scrubber?
The brush is the scrubber. For hand scrubbing, an 18-inch nylon brush on a rigid telescoping pole gives you the reach and leverage to actually scour walls and floor. If by scrubber you mean something that does the work for you, a robotic pool cleaner scrubs and vacuums the floor and walls automatically on a cycle, though it will not scrub steps and tight corners as well as you can by hand. Most owners use both: the robot for routine floor cleaning and a brush for the spots it misses.
How many times a week should you brush your pool?
Brush at least once a week under normal conditions, focusing on the low-flow dead spots: steps, corners, behind ladders, and the deep-end floor. Step up to two or three times a week, or daily, when you are clearing algae or after a storm dumps debris and organics into the water. During an active algae treatment, daily brushing matters because it breaks up the protective film so your sanitizer can reach the algae. A weekly brush plus balanced water is what keeps a pool from turning on you.
What's the best thing to clean a pool with?
No single tool does it all; a clean pool comes from three things working together. A brush loosens dirt, algae, and biofilm off the walls and floor. A vacuum or robotic cleaner then removes what the brush loosened, since brushing moves debris but does not take it out of the water. And balanced chemistry, especially free chlorine held in range with the chlorine calculator, keeps algae and cloudiness from coming back. Skip any one of the three and you end up fighting the water.
Can you use a stainless steel brush on a vinyl or fiberglass pool?
No. Stainless-steel bristles will gouge a vinyl liner and scratch a fiberglass gelcoat, and the damage is permanent. Stainless brushes are only for unpainted concrete, gunite, and plaster, which are hard enough to take the metal. On a vinyl or fiberglass pool, use a nylon brush for everyday cleaning and a stiffer nylon algae brush if you have an algae problem. When in doubt about your surface, stick with nylon; it cleans well and cannot hurt anything.
