- 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.
Pros
- Genuine Beatbot quality ensures perfect fit and compatibility with AquaSense 2 and AquaSense series robots.
- Enhanced durability with wear-resistant PVC material that stands up to frequent pool cleaning.
- Wider cleaning coverage thanks to the 146mm extra-long roller brush design.
- Efficient scrubbing with 48 brush pieces per roller and 45 degree water outlet design.
- 4-pack value means you always have a spare brush ready when needed.
Cons
- Only compatible with Beatbot AquaSense 2 and AquaSense series cleaners, not universal or for other brands.
- Priced at a premium compared to generic aftermarket alternatives, though it is a genuine replacement part.
- Requires periodic inspection and timely replacement to maintain peak performance, adding to long-term maintenance costs.
The Beatbot Genuine Replacement Brush for AquaSense 2 Series and AquaSense Series is a must-have maintenance item for owners of these cordless robotic pool cleaners. Designed to fit all four brush positions on AquaSense Pro and compatible with AquaSense 2 Ultra, AquaSense 2 Pro, AquaSense 2, and original AquaSense models, this brush delivers genuine performance that aftermarket parts often fail to match.
For real-world performance, the extra-long 146mm roller brush combines with a 45 degree angled water outlet to scrub away stains, debris, and dirt buildup without creating drag. Each roller skin contains 48 brush pieces, and when two brushes work together on AquaSense Pro, they cover a wide 305mm area per pass. That means less time cleaning and more time enjoying the pool.
Build quality is a clear highlight. The brush is made from advanced PVC wear-resistant material, so it stands up to rough scrubbing on concrete, tile, and vinyl surfaces while staying gentle on liners. The pack includes four replacements, which makes it easy to keep your robot in top shape without frequent reordering.
One consideration is that these brushes are specifically designed for the AquaSense series, so they won't work with other robotic pool cleaners. The genuine part price is also higher than generic options, but for owners who want reliable performance and extended robot lifespan, the investment is justified.
Overall, this replacement brush pack is a smart choice for AquaSense owners who prioritize genuine compatibility, durable construction, and thorough cleaning. If you want to maintain peak suction and scrubbing power, swapping in these brushes when the originals wear down is a simple and effective way to keep your pool sparkling.
Buying Guide: How to Choose a Replacement Brush
Compatibility with Your Cleaner Model
Not all brushes fit every robot. Always confirm your pool cleaner model number and brush part number before purchasing. Dolphin models use specific part numbers like 6101641-R2 or 9983122-R1. Aftermarket options often list multiple compatible models, but double-check the brush shape and mounting configuration. If you are unsure, see our best pool robot brush kit guide for model-specific recommendations.
Material Quality and Durability
Brushes made from high-toughness elastic or wear-resistant PVC last longer and resist pool chemicals, sunlight, and friction. Genuine Maytronics parts use premium materials that maintain scrubbing power over many cleaning cycles. Aftermarket brushes can be just as durable if they use similar compounds. Avoid brushes that feel flimsy or have thin bristles.
Brush Type: Climbing, Scrubbing, or Combo
Some brushes are designed primarily for wall climbing, others for floor scrubbing, and many combine both functions. The Dolphin 6101641-R2 grey brushes serve both scrubbing and climbing roles. If your robot struggles on walls, a dedicated climbing brush may be the answer. For more on traction, read our best pool robot traction brush article.
OEM vs. Aftermarket: Which to Choose?
OEM parts from Dolphin or Beatbot guarantee perfect fit and performance, but they often cost more. Aftermarket brands like LBLVBNEWD, BGD, and Pooloob offer reliable alternatives at lower prices. Many aftermarket brushes are made from equivalent materials and include upgrades like integrated designs for easier installation.
