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: Choosing the Best Dolphin Middle Brush Replacement
Selecting the right brush involves more than just matching a part number. Here are the key factors to consider before purchasing a replacement for 2026.
Compatibility with Your Dolphin Model
Not all brushes fit every Dolphin cleaner. Check your model number against the product listing. Many brushes, like the 6101641-R2 Front Rear Brush Set Compatible, are designed for multiple models including Nautilus Plus, DX3, DX4, and Premier. Others are specific to the Active series or M600. Always compare the brush shape, length, and mounting configuration with your existing part before ordering. For a broader look at compatible parts, visit our Replacement Brushes category.
Material and Build Quality
Brushes made from high-toughness elastic materials resist pool chemicals, sunlight, and friction. Premium options, such as the Pool Cleaner Rear Brushe Replacement Parts, use an upgraded integrated structure that prevents missing parts and simplifies installation. Look for dense synthetic bristles that maintain shape over time. Genuine Dolphin parts like the Dolphin Genuine Replacement Part (grey brushes) offer certified durability.
Ease of Installation
Most replacement brushes are designed for tool-free removal and installation. Some models require you to remove the old roller brush and its connecting port, so read instructions carefully. Integrated designs, like the one from LBLVBNEWD, simplify the process by combining all components into a single unit. If you prefer a quick swap, look for products that snap into place without extra steps. For more tips, see our article on pool robot brush replacement parts.
Performance for Climbing and Scrubbing
The primary role of the middle brush is to help your cleaner climb walls and scrub dirt effectively. Worn brushes lose traction and leave streaks. Replacement brushes with aggressive bristle patterns, such as the BGD 6101641-R2 Grey Climbing Brushes for Dolphin, restore grip and cleaning power. Consider your pool’s surface: smooth tile may need softer bristles, while textured concrete benefits from stiffer ones.
Final Thoughts
Choosing the right middle brush replacement keeps your Dolphin pool cleaner performing at its best. For a durable, integrated rear brush that simplifies installation, the Pool Cleaner Rear Brushe Replacement Parts is an excellent choice. If you need a reliable climbing brush set for multiple models, the BGD 6101641-R2 Grey Climbing Brushes for Dolphin offers great value and proven compatibility. Both options are verified for 2026 and will help your robot glide smoothly across walls and floors.

Frequently Asked Questions
How often should I replace the middle brush on my Dolphin pool cleaner?
Most manufacturers recommend replacing brushes every 6 to 12 months, depending on usage and pool conditions. If you notice reduced climbing ability or visible wear on the bristles, it is time for a replacement. For seasonal guidance, see our brush and ring replacement kit article.
Can I use a front brush as a middle brush replacement?
Middle brushes are typically the rear or climbing brushes that provide traction. Front brushes focus on scrubbing. While some sets include both, you should always use the designated brush for each position to ensure proper movement and cleaning.
Are aftermarket brushes as good as genuine Dolphin parts?
Many aftermarket brushes, like those from BGD and LBLVBNEWD, use high-quality materials and are designed to match OEM specifications. They often cost less while delivering similar performance. Always check reviews and compatibility before purchasing.
What if my brush does not fit after purchase?
Double-check your cleaner model and compare the brush dimensions with the product images. Most sellers offer returns or exchanges if the part is incompatible. Contact the seller via Amazon for assistance. For a wide selection of verified fits, browse our top replacement pool cleaner brushes.
