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.
What to Look for in a Dolphin Rear Brush Replacement
Compatibility with Your Dolphin Model
Not all rear brushes fit every Dolphin model. Some brushes are designed for the M600 series, while others work with Nautilus or DX models. Always check your robot’s part number and brush connection style before purchasing. For a broader overview of compatible parts, see our best pool robot brush replacement parts guide.
Material Quality and Durability
Rear brushes made from high-toughness elastic materials resist water corrosion and frequent friction. Look for brushes that won’t soften, crack, or lose their anti-slip properties after months of use. Premium materials extend the replacement interval and keep your cleaner performing consistently.
Ease of Installation
Many modern rear brushes feature integrated designs that simplify replacement. You may need to remove the old brush and its connecting port, but most kits include instructions or even a screwdriver. Quick installation means less downtime for your pool cleaner. If you are on a budget, our best budget replacement pool cleaner brushes guide offers great options.
Restoring Traction and Cleaning Performance
A worn rear brush causes the cleaner to slide backward on walls and miss debris. The right replacement restores stable movement and consistent scrubbing. Many users report noticeable improvement after swapping out the old brush. For more tips, check our top pool cleaner brush and ring replacement kits.
