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 the Right Brush Replacement
Compatibility with Your Robot Model
Not all brushes fit all robots. A brush that works for a Dolphin Nautilus may not fit a Beatbot AquaSense. Before ordering, verify your exact model number and compare the brush shape, mounting points, and dimensions. Many listings include a compatibility list, but variations exist between production runs. When in doubt, measure your old brush and match it to the images provided. For Dolphin owners, our dolphin nautilus CC plus tracks may also help you identify the correct parts.
Brush Material and Durability
Pool chemicals, sunlight, and constant friction wear down brushes over time. Look for brushes made from high-toughness elastic materials, wear-resistant PVC, or genuine OEM grade plastics. Cheaper brushes may soften or deform after a few months, reducing scrubbing power. Premium options like the Beatbot genuine brush use advanced PVC that resists corrosion and maintains stiffness for consistent cleaning.
Front vs. Rear Brushes and Complete Sets
Some robots use separate front and rear brushes, while others use a single roller brush. Replace both simultaneously to ensure balanced scrubbing and traction. Many kits include two brushes (front and rear) along with rubber rings or climbing rings. For example, the Pooloob PF1 kit includes both cleaning brushes and wheel rubber rings, addressing the most common wear points at once. If your robot has a rear brush assembly that also serves as a wheel, make sure the replacement includes the correct mounting connector.
OEM vs. Aftermarket Parts
Genuine OEM parts from brands like Dolphin or Beatbot guarantee exact fit and performance, but they often cost more. Aftermarket options from brands like Pokin, BGD, and LBLVBNEWD can save money while still delivering good results. However, aftermarket brushes may vary in bristle stiffness or rubber compound. Read recent buyer feedback and look for listings that specify upgraded materials or integrated designs that simplify installation.

Final Thoughts
Whether you need a quick fix for a worn rear brush or a complete set of front and rear replacements, the market has strong options for every budget. For Dolphin owners who want guaranteed fit and durability, the Dolphin Genuine Replacement Part is a reliable choice that comes directly from the manufacturer. If you are looking for a cost-effective solution that covers both brushes and traction rings, the Pooloob PF1 Robotic Pool Cleaner Replacement Parts kit offers exceptional value for the Pooloob PF1. Whichever you choose, replacing worn brushes is a simple DIY task that will restore your robot’s cleaning performance and extend its life.

Frequently Asked Questions
How often should I replace my robotic pool cleaner brushes?
Most manufacturers recommend replacing brushes every six to twelve months, depending on usage and pool conditions. If you notice the robot leaving debris behind, slipping on walls, or making unusual noises, it is time to inspect the brushes. In 2026, many aftermarket brushes are made with longer-lasting materials, but regular checks remain important.
Can I use aftermarket brushes on my Dolphin robot?
Yes, many aftermarket brushes are designed to fit Dolphin models and work well. However, ensure the brush part number matches your robot’s configuration. For example, the 6101641-R2 brush is used across many Dolphin models like the Nautilus Plus, DX3, and Premier. Always compare the shape and mounting before buying.
What is the difference between front and rear brushes?
Front brushes typically scrub the pool floor and walls, while rear brushes provide traction and help the robot climb. Some robots use a single brush for both functions. Replacing both at the same time ensures balanced performance. For models like the Dolphin M600, the rear brush assembly also includes the wheel, so you need a complete replacement part.
Do I need to replace the rubber rings or tracks at the same time?
It is a good idea to inspect rubber rings and tracks when replacing brushes. Worn rings can cause slipping and reduce climbing ability. Some kits, like the Pooloob PF1 set, include both brushes and rubber rings for a complete refresh. For track-driven robots, see our dolphin nautilus replacement tracks for options.
