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
- Active scrubber brush lifts tough dirt and algae without harming pool liners
- Top-load filter basket is easy to access and clean
- Smart navigation adapts to any pool shape or surface
- Plug-and-play operation requires no tools or professional setup
- Trusted brand with decades of experience in robotic pool cleaners
Cons
- No app or remote control, so you can't schedule or monitor cleaning from your phone
- Corded design may limit range and requires occasional repositioning for larger pools
- Filter basket may need frequent emptying if the pool has heavy debris
The Dolphin Proteus DX1 is an automatic robotic pool vacuum cleaner designed for above-ground and small in-ground pools up to 33 feet. It is ideal for homeowners who want to spend less time scrubbing and more time swimming, especially those who value simple, plug-and-play operation.
At the heart of this cleaner is an active scrubber brush that aggressively loosens dirt, algae, and grime without damaging pool liners. The smart navigation system scans the pool to plot the most efficient cleaning path, ensuring coverage across all surfaces and shapes. Its top-load filter basket captures debris and makes emptying a quick, no-fuss task.
The Proteus DX1 is compact and lightweight at under 15 pounds, which makes lifting it out of the water and rolling it away simple. The white finish suits most pool surroundings, and the construction reflects Dolphin's 40-plus years of pool cleaning expertise. There is no complicated wiring or app setup, just a straightforward connect and clean routine.
The main trade-off is the lack of smart connectivity or remote scheduling. You won't be able to set cleaning timers or control the robot from your phone. A corded power supply can also limit range, so you need to reposition the unit for very large pools, and the filter basket may require regular emptying if heavy debris is present.
Overall, the Dolphin Proteus DX1 is a reliable and effective option for pool owners who value straight-ahead cleaning performance over extra smart features. It pairs a proven cleaning system with easy maintenance, making it a solid choice for hassle-free pool care. If you want a no-frills robotic vacuum that gets the job done in under two hours, this machine delivers.
The Dolphin Proteus DX1 comes in a white finish and has a compact footprint of 17.19 x 15.78 x 10.39 inches. It weighs just 14.62 pounds, making it portable and easy to store.
This model is designed for pools up to 33 feet in length and falls under the Lawn & Patio product category. It features a top-load filter basket and a plug-and-play power system for simple, direct operation.
Buying Guide: Choosing Between Active and Standard Brushes
Brush Design and Function
Active brushes (often called scrubber brushes) use denser, stiffer bristles that rotate aggressively to dislodge stubborn algae and dirt. Standard climbing brushes have softer bristles that prioritize traction on walls. For example, the Dolphin Genuine Replacement Part Active Front Grey Brush is an active brush designed for models like Nautilus CC and Triton PS. In contrast, the Dolphin Genuine Replacement Part Front and Rear Grey Brushes are standard climbing brushes for many Dolphin robots.
If your pool has heavy debris or you notice your robot skipping surfaces, an active brush may provide better scrubbing. For routine maintenance and reliable wall climbing, standard brushes are sufficient.
Compatibility Across Models
Not every brush fits every Dolphin. Active brushes often share part numbers like 9983122-R1, which fits dozens of models including the Dolphin Proteus DX1 and M600. Standard brushes use part numbers like 6101641-R2, which are compatible with Nautilus Plus, Premier, and many others. Always verify your robot’s exact model before ordering. The BGD 6101641-R2 Grey Climbing Brushes are a direct replacement for standard climbing brushes on compatible Dolphin robots.

Material and Durability
Active brushes use reinforced synthetic bristles that resist wear from saltwater and chlorine. Standard climbing brushes also use durable materials but may wear faster if used on rough pool surfaces. The Doule King Replacement Rear Dynamic Brush is specifically built for the rear position of the Dolphin M600, offering extra stability during wall climbs. If you want a long-lasting active brush, consider the XZFYSM Replacement for Dolphin Maytronics Grey Active Brush, which is an affordable aftermarket alternative.
Check the brush construction: stiff bristles for active scrubbing, softer bristles for climbing. Both types are designed to last through many cleaning cycles.
Single vs Dual Brush Kits
Some kits include only a front or rear brush, while others provide a pair. The Front Brush Replacement Front Brushes Parts is a single front brush for many models, ideal if only one side is worn. For complete refresh, the Dolphin Genuine Replacement Part Front and Rear Grey Brushes gives you both. If you own a Dolphin Proteus DX1 with active scrubbing, the Dolphin Proteus DX1 Automatic Robotic Pool Vacuum comes with an active brush built in, so you only need replacement brushes later.
Consider whether your robot uses identical brushes front and rear or different ones. Many newer Dolphin models use an active brush on the front and a standard climbing brush on the rear.
Final Thoughts
Choosing between a Dolphin active brush and a standard brush comes down to your pool’s needs. For heavy debris and persistent algae, the active scrubber brush like the Dolphin Genuine Replacement Part Active Front Grey Brush delivers superior cleaning power. For reliable wall climbing and routine maintenance, the standard climbing brush set such as the Dolphin Genuine Replacement Part Front and Rear Grey Brushes offers proven performance at a lower cost. Whichever you choose, replacing worn brushes every season keeps your Dolphin robot running efficiently.

Frequently Asked Questions
What is the difference between an active brush and a standard brush on a Dolphin pool cleaner?
An active brush uses stiffer, denser bristles that rotate with more force to scrub dirt and algae from pool surfaces. A standard brush has softer bristles that focus on providing traction for wall climbing and gentle cleaning. Both are essential but serve different roles.
Can I use an active brush on any Dolphin robot?
No. Active brushes like the 9983122-R1 are only compatible with specific models such as the Dolphin Nautilus CC, Triton PS, and Proteus DX3/DX4. Always check your robot’s model number before purchasing. Visit our comparisons page to see model guides.
How often should I replace my Dolphin pool cleaner brushes?
Replace brushes every 12 to 18 months, or sooner if you notice reduced wall climbing, uneven cleaning, or visible wear. In 2026, many owners replace them at the start of the swimming season for peak performance.
Are aftermarket brushes as good as genuine Dolphin brushes?
Many aftermarket brushes from brands like Pokin, BGD, and XZFYSM offer similar quality at a lower price. They are often made with durable synthetic bristles and fit precisely. Genuine Dolphin brushes provide guaranteed compatibility and are certified by Maytronics. Both options can restore your robot’s performance.
