Buying Guide: How to Choose the Best Robotic Pool Cleaner Brush Set
Compatibility with Your Cleaner Model
Not all brushes fit every robot. Dolphin units like the Nautilus CC Plus and Premier use specific climbing and scrubbing brush configurations (e.g., part 6101641-R2). Polaris models such as the 9300xi require a ribbed brush design (R0528900). Always check your owner manual or the existing part number before ordering. Third-party brands like Pokin and BGD offer cost-effective alternatives that match OEM dimensions, but it is wise to compare length, end connectors, and mounting clips to ensure a snug fit.
Brush Type: Scrubbing vs. Climbing
Robotic cleaners use different brush roles. Climbing brushes help the robot scale walls and maintain traction on slopes, while scrubbing brushes agitate dirt and algae from surfaces. Some sets combine both functions. For example, the grey climbing brushes used in many Dolphin models are designed to rotate and scrub simultaneously. If your robot struggles with wall climbing, the climbing brush may be worn smooth. Replacing it with a fresh set can restore performance.
Bristle Material and Durability
Bristles are typically made from nylon, polypropylene, or rubber compounds. Nylon bristles are gentle on vinyl and fiberglass, while firmer polypropylene works well on concrete and gunite. Rubber or polymer blades are ideal for scrubbing without scratching. Look for brushes that resist chlorine, salt, and UV degradation. Sets from ZYROA and Sepetrel often use high-density bristles that hold their shape even after repeated cycles. Replace brushes as soon as you notice fraying, cracking, or loss of flexibility.
Ease of Installation and Value
Most replacement brushes snap in or slide into designated slots with no tools required. Dolphin brushes often use a simple clip system, while Polaris brushes may have squeeze-release tabs. A set that includes two or four brushes offers better value than buying singles. Consider multipacks like the 4-pack for Zodiac/Polaris units. If you prefer OEM-look parts, the BGD and Pokin sets offer excellent quality at a lower price point than the original manufacturer. For more brand-specific advice, see our collection of best dolphin replacement brushes and best Polaris replacement brushes.
Final Thoughts
Choosing the right brush set ensures your robotic pool cleaner continues to operate at peak efficiency, saving you time and manual labor. For Dolphin owners who want a direct match, the 6101641-R2 Front Rear Brush Set Compatible is a reliable drop-in replacement that restores wall-climbing and scrubbing power. If you own a Polaris 9300xi or similar model, the Polaris R0528900 9300xi Replacement Brush for Pool provides the ribbed design needed for effective debris pickup. Both options come highly rated and are built to last through many cleaning cycles, making them smart investments for maintaining a sparkling pool.

Frequently Asked Questions
How often should I replace the brushes on my robotic pool cleaner?
In most cases, you should inspect brushes every three to six months, depending on pool usage and chemical balance. If the bristles are frayed, flattened, or missing, it is time for a replacement. For heavy-use pools, annual replacement is typical.
Can I use third-party brushes on my Dolphin or Polaris cleaner?
Yes, many third-party brushes are designed to meet or exceed OEM specifications. Brands like Pokin and BGD produce brushes that fit Dolphin models perfectly, while ZYROA offers compatible sets for Zodiac and Polaris. Just verify the part number before ordering.
What is the difference between climbing brushes and scrubbing brushes?
Climbing brushes help the robot grip and ascend walls, while scrubbing brushes agitate dirt and algae from the pool surface. Many modern brush sets combine both functions in one piece, rotating to scrub as the robot moves.
Will a brush set improve the wall-climbing ability of my robot?
Absolutely. Worn climbing brushes lose their traction, causing the robot to slip or stall on walls. Replacing them with a fresh set can restore 90% of the original climbing performance, even in older models. For more tips, check out our guide on best pool cleaner replacement brushes.
