Your gunite pool is built to last, but the constant friction of robotic pool cleaner brushes against that rough plaster surface can wear them down faster than you expect. When the bristles flatten or the rollers lose their grip, your cleaner starts leaving streaks on the floor and struggles to climb the walls. The right replacement brush restores deep scrubbing power and keeps your robot moving efficiently. In this guide, we evaluate ten top replacement brushes and rollers specifically suited for gunite pools, covering compatibility, durability, and cleaning performance.
Whether you own a Dolphin, Polaris, Zodiac, or Hayward model, we have options that fit your machine and your budget. For more on keeping your pool pristine, check out our roundup of the best pool cleaner scrubbing brushes for fiberglass pools as well.
Pros
- Compatible with a wide range of Dolphin models
- Restores climbing ability and scrubbing performance
- Affordable replacement compared to buying new robot

The BGD 6101641-R2 Grey Climbing Brushes are a replacement set designed for Dolphin robotic pool cleaners, specifically models like the M200, DX3, and DX4. They come as a two-pack to replace both front and rear brushes, restoring the robot's ability to scrub pool floors and climb walls effectively.
These brushes are engineered to rotate with the robot's movement, dislodging dirt and debris while maintaining traction on vertical surfaces. Users can expect a noticeable improvement in cleaning performance once worn brushes are replaced, making this a cost-effective maintenance solution.
Build quality appears solid with grey composite bristles that resist wear and water damage. The set includes two identical brushes, but buyers must verify the shape, length, and mounting configuration of their existing brushes to ensure compatibility, as similar-looking robots may use different assemblies.
One potential drawback is the lack of customer reviews, so real-world longevity is unconfirmed. Additionally, compatibility varies by robot revision, so double-checking your model number is essential before purchase.
Overall, the BGD 6101641-R2 brush set offers a reliable and affordable way to keep your Dolphin pool cleaner performing at its best. If you need to restore scrubbing and climbing function, this two-pack is a smart choice.
Buying Guide for Robotic Pool Cleaner Replacement Brushes for Gunite Pools
Compatibility with Your Robotic Cleaner
Not every brush fits every robot. You must match the part number or brush configuration to your specific model. Many brushes are designed for Dolphin, Polaris, Zodiac, or Hayward units, but even within a brand, revisions matter. Always verify the existing brush shape, length, and mounting before ordering.
Generic brushes that claim universal fit can cause poor scrubbing or even damage. Stick to options that list your exact robot model, like the BGD 6101641-R2 set that fits Dolphin M200, DX3, and many others.

Brush Material and Durability for Gunite Surfaces
Gunite is abrasive. Soft nylon bristles can wear quickly, while stiffer materials like polypropylene or reinforced nylon hold up longer. Look for brushes labeled as heavy-duty or designed for rough surfaces. The PEUTIER 7-pack uses soft nylon that works on vinyl but may need frequent replacement on gunite.
For gunite, consider brushes with thicker bristles or cyclonic action that keeps debris in motion. The ATIE cyclonic scrubbing brushes constantly spin, reducing drag and extending brush life. Pairing a durable brush with a fine filter upgrade, like the ones in our best pool robot filter basket for above ground pools article, keeps your pool cleaner running longer.
Scrubbing Efficiency and Climbing Performance
A brush that doesn’t scrub effectively leaves algae and dirt behind. For gunite pools, you need brushes that agitate debris while maintaining traction on walls. The Dolphin Genuine Replacement Active Brush is engineered for both scrubbing and climbing, with a grey brush that rotates to lift stubborn grime.
Climbing brushes like the BGD set combine scrubbing bristles with a design that helps the robot grip vertical surfaces. Worn belts or rollers can also hinder climbing; the RCX23002 Belt & Brush Kit from MNPARTS restores both traction and scrubbing in one package.

Ease of Installation and Maintenance
Most replacement brushes snap on or screw in without special tools. Kits like the Sepetrel Replacement Brush Roller Set for SP251 are designed for direct fit and quick swap. If you prefer minimal downtime, choose a set that includes multiple brushes or rollers so you have a backup ready.
Some brushes, like the Pooloob PF1 kit, also include wheel rubber rings to improve traction. Regular inspection of brushes and belts extends your robot’s lifespan. Combine a brush replacement with a new filter from our best robotic pool cleaner replacement filters for above ground pools list for a complete refresh.
Final Thoughts
Choosing the right replacement brush for your gunite pool comes down to matching your robot model and prioritizing durability. For a budget-friendly option that covers basic scrubbing and traction, the Pooloob PF1 Robotic Pool Cleaner Replacement Parts kit is a solid choice. If you own a Dolphin cleaner and want OEM-level performance, the Dolphin Genuine Replacement Part active brush delivers reliable scrubbing and climbing. Either way, keeping your brushes fresh ensures your robotic cleaner handles gunite surfaces effectively season after season.

Frequently Asked Questions
How often should I replace robotic pool cleaner brushes on a gunite pool?
For gunite pools, check brushes every three to six months. If you notice reduced scrubbing or the robot slipping on walls, it is time to swap them out. Regular replacement prevents strain on the motor and keeps cleaning efficient.
Can I use generic replacement brushes on my Dolphin robotic cleaner?
Yes, but only if the generic brush matches the exact part number and dimensions. Dolphin models use specific brush configurations, so verify compatibility before buying. The BGD 6101641-R2 set is a popular third-party option that fits many Dolphin units.
What is the best brush material for gunite pool surfaces?
Stiff nylon or polypropylene bristles hold up best against gunite’s abrasive texture. Avoid soft brushes that wear quickly. Cyclonic brushes, like those from ATIE, combine durable materials with spinning action to reduce friction and extend lifespan.
Do replacement brushes affect my robot’s ability to climb walls?
Absolutely. Worn brushes lose the grip needed to climb. Climbing brushes, such as the BGD grey set, are designed with a combination of scrubbing bristles and a shape that helps the robot maintain contact. Replace both brushes and belts if climbing declines.
