- 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.

- 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
Compatibility with Your Pool Robot Model
The most critical factor is ensuring the brush assembly fits your specific robot. Many assemblies are designed for popular brands like Dolphin, Beatbot, or CoasTeering. Always verify part numbers and dimensions before purchasing. For example, the BGD 6101641-R2 Grey Climbing Brushes are tailored for Dolphin M200 and DX3 series, while the Beatbot Genuine Replacement Brush is exclusive to the AquaSense line. For more on compatibility, read our guide on rear brush replacements.
Material Quality and Durability
Pool chemicals and constant water exposure demand brushes made from resilient materials. Look for PVC or reinforced polymer construction that resists cracking, warping, and chlorine damage. The Hosrivae Wheel Tube & Brush Assembly M400 CC uses long-lasting PVC, while the Floor Wall Scrubbing Roller Brush Assembly features chlorine-resistant construction. Durable brushes extend the life of your robot and maintain scrubbing power.
Brush Design and Scrubbing Efficiency
The brush’s density, bristle length, and shape directly affect cleaning performance. Ribbed or bristled designs excel at removing stubborn debris from floors and walls. The Beatbot Genuine Replacement Brush includes 48 brush pieces per roller for meticulous cleaning, while the Pool Robot Replacement Brush Roller Assembly uses dense ribbed rollers for heavy-duty scrubbing. For more insights, see our active brush replacement guide.
Ease of Installation
No one wants a complicated replacement process. Many modern brush assemblies are designed for direct swap with no tools required. The LBLVBNEWD Pool Cleaner Rear Brushe Replacement Parts features an integrated structure that simplifies installation, while the Wheel Tube Roller Brush Assembly 99955951-ASSY includes climbing rings and a tube for a complete drop-in upgrade.
