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: What to Look for in Dolphin Active 20 Replacement Brushes
Choosing the right brush set involves more than matching a part number. Here are the key factors we consider when evaluating replacements for the Dolphin Active 20.
Compatibility with Your Dolphin Model
Not all brushes fit every version of the Active 20. The Active 20 uses the 6101641-R2 configuration for its front and rear climbing brushes, but some models also require the active front brush (9983122-R1). Always check your robot’s model number and brush part number before ordering. For instance, the 6101641-R2 Front Rear Brush Set Compatible is designed for many Dolphin models, but verifying your specific unit avoids returns. If you own a different Dolphin model, our guide to Dolphin E20 brushes may be helpful.
Bristle Quality and Density
The bristles do the actual scrubbing. Dense, resilient synthetic bristles remove algae, dirt, and fine debris more effectively than soft or sparse ones. Look for brushes made from materials that resist chlorine and saltwater. The Dolphin Genuine Replacement Part set uses Maytronics-certified bristles that maintain their stiffness over many cleaning cycles. Third-party options like the BGD 6101641-R2 set also offer dense grey bristles designed for climbing and scrubbing.
Ease of Installation
You want to spend your time enjoying the pool, not wrestling with tools. Most replacement brushes snap into place without screws or special tools. The Front Brush Replacement Front Brushes Parts from IdealThingShop highlight tool-free removal and installation, making the swap a quick process. Still, confirm that the brush ends match your robot’s mounting points. A secure fit prevents the brush from slipping during operation.
OEM vs. Third-Party Options
Genuine Dolphin parts, like the Dolphin Genuine Replacement Part, Active Front Grey Brush, guarantee exact fit and material quality. They cost more but often last longer. Third-party brushes from brands like XZFYSM or YCVNVB can save money, but verify customer feedback on longevity and fit. Some third-party sets include extra components like drive gears and bushings, which can be a bonus if your robot also needs mechanical repairs.

Final Thoughts
After reviewing the top contenders, we believe the best overall choice for most Dolphin Active 20 owners is the Dolphin Genuine Replacement Part set, thanks to its OEM quality, reliable climbing performance, and proven durability. If you prefer a more affordable option that still delivers excellent scrubbing and wide compatibility, the 6101641-R2 Front Rear Brush Set Compatible from Pokin offers outstanding value. Whichever you choose, replacing worn brushes will restore your pool cleaner’s ability to tackle dirt and keep your water sparkling all season long.

Frequently Asked Questions
How often should I replace the brushes on my Dolphin Active 20?
Most manufacturers recommend replacing the brushes every 6 to 12 months, depending on pool usage and water chemistry. If you notice reduced scrubbing, the robot struggling to climb walls, or visible wear on the bristles, it is time for a new set. Check your unit’s manual for specific intervals, but a general rule is to inspect the brushes at the start of each swimming season in 2026.
Can I use brushes from other Dolphin models on the Active 20?
Only if the part numbers match. The Active 20 uses the 6101641-R2 climbing brushes and the 9983122-R1 active front brush. Brushes from the Dolphin Nautilus or E10 series may look similar but have different dimensions or mounting clips. Always verify compatibility by checking your robot’s model and the product listing. For help with other Dolphin models, read our Dolphin E10 replacement brush guide.
What is the difference between the front brush and the climbing brushes?
The front active brush (often grey) rotates to scrub the pool floor and walls, while the climbing brushes (front and rear) help the robot grip and ascend vertical surfaces. Both are essential for thorough cleaning. Some replacement sets include only climbing brushes, so check if you need both types. The Dolphin Genuine Replacement Part set (6101641-R2) includes both front and rear climbing brushes, while the active front brush is sold separately.
Are third-party brushes as good as genuine Dolphin brushes?
High-quality third-party brushes can perform nearly as well as OEM parts, especially if they use dense synthetic bristles and precise molds. However, genuine Dolphin brushes are certified to match the exact specifications of your robot, which often results in longer life and better fit. For the Active 20, we found that both the genuine Dolphin set and the Pokin 6101641-R2 set deliver excellent scrubbing and climbing ability.
