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.

The Zymurgoes Tune-Up Kit is a purpose-built replacement parts bundle for the Maytronics Dolphin Nautilus CC Plus robotic pool cleaner. This kit targets owners who want to restore their cleaner's peak performance without the hassle of sourcing individual parts. It is an excellent choice for maintaining a clean pool without professional help.
Standout features include both fine and ultra-fine filter cartridges, allowing the cleaner to trap everything from leaves and twigs to fine sand and dust.

Buying Guide
nCompatibility: Confirm Your Model
nNot all brushes fit every Dolphin Nautilus model. The most common part number is 6101641-R2, which fits Nautilus CC Plus, DX3, DX4, M200, and many others. However, older Nautilus models may require the light blue brush set (6101609-R2). Always check your robot’s manual or existing brush part number before ordering. Genuine Dolphin parts guarantee a perfect fit, while third-party brands like Pokin and BGD offer compatible alternatives that work just as well.

nBrush Type: Climbing vs. Active vs. Tune-Up Kits
nDolphin brushes come in different designs. Grey climbing brushes (6101641-R2) scrub dirt while helping the robot climb walls. Active brushes (9983122-R1) provide extra scrubbing power for stubborn debris. Some tune-up kits bundle brushes with filters, tracks, and climbing rings for a full refresh. If only the brushes are worn, buying just the brush set saves money. If other parts are also degraded, a kit like the Hihitomorrow or Yoursme tune-up kit offers better value.
nMaterial Quality and Durability
nGenuine Dolphin brushes use high-grade polypropylene bristles that resist wear from sun and chemicals. Third-party brands often use similar materials, but lower-cost options may wear faster. The Pokin set claims premium durability, and BGD’s brushes are reinforced for long life. Check customer feedback to confirm reliability. For heavy-duty use, investing in OEM parts is recommended, but for budget-conscious owners, aftermarket sets can extend your robot’s lifespan without breaking the bank.
nFinal Thoughts
nYour Dolphin Nautilus deserves brushes that restore its original cleaning power. For owners who want direct factory quality, the Dolphin Genuine Replacement Part offers reliable performance at a fair price. If you prefer a cost-effective alternative that fits many models, the BGD 6101641-R2 Grey Climbing Brushes for Dolphin deliver strong scrubbing and great value. Either choice will keep your pool sparkling clean for 2026 and beyond.

Frequently Asked Questions
nHow often should I replace my Dolphin Nautilus brushes?
nMost manufacturers recommend replacing brushes every 6 to 12 months, depending on use. If you notice reduced scrubbing or climbing ability, inspect the bristles for wear and swap them out. Using your robot weekly in a heavy-use pool may require more frequent replacement.
nAre aftermarket brushes as good as genuine Dolphin parts?
nHigh-quality aftermarket brands like Pokin and BGD offer brushes that meet or exceed OEM specifications. They are often cheaper but should still provide excellent cleaning. Always check that the part number matches your robot’s requirements and read user reviews to confirm durability.
nWhat is the part number 6101641-R2?
n6101641-R2 is the most common Dolphin brush part number used in Nautilus CC Plus, DX3, DX4, M200, Premier, and many other models. It refers to a set of two grey climbing brushes that scrub pool surfaces and help the robot climb walls. Verify your existing brush before ordering to ensure compatibility.
nCan I use a tune-up kit instead of just brushes?
nYes, tune-up kits like those from Hihitomorrow or Zymurgoes include not only brushes but also filters, climbing rings, and tracks. If your robot is several years old or exhibiting poor movement, a full kit can restore its performance to like-new condition. If only the brushes are worn, a standalone brush set is sufficient.
