- 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: What to Look for in an Aftermarket Pool Robot Brush
Choosing the right replacement brush means matching your robot model and understanding what you need from the brush material. Here are four key criteria to consider before buying.
Compatibility with Your Robot Model
Not all brushes fit all robots. Many aftermarket sets are designed for specific series like Dolphin Nautilus, DX3/DX4, or Zodiac MX8. Always verify the part number (e.g., 6101641-R2) and compare shape, length, and mounting holes. A precise fit prevents jamming and ensures proper scrubbing.
For a broader look at OEM versus aftermarket fit, see our comparison of OEM and compatible brushes.
Brush Material and Durability
Aftermarket brushes use nylon, polymer, or rubber composites. Nylon bristles offer gentle but effective cleaning for vinyl or fiberglass pools. Stiffer polymer blends tackle tile grout and concrete stains. Rubber rings or treads improve climbing traction. Look for UV-resistant and chemical-resistant materials if you use chlorine or salt systems.
Scrubbing Performance and Coverage
Brushes with more bristle rows or longer roller lengths clean more area per pass. Cyclonic or spinning brush designs (like those for Zodiac) actively lift debris from walls and floors. Some aftermarket sets include multiple brush types (scrub, climbing, roller) to address different surfaces. If your pool has algae or stains, prioritize heavy-duty scrubbing bristles.

Pack Size and Value
Brushes wear out over time, so buying multi-packs saves money and hassle. Kits with two or four brushes allow you to replace front and rear sets at once. Some sets include extra parts like wheel rings or clip-in adapters. Balance the per-brush cost against expected lifespan, cheaper brushes may need frequent replacement.
Final Thoughts
After reviewing these ten aftermarket brush kits, two stand out for different needs. For Dolphin owners who want a direct fit with proven durability, the BGD 6101641-R2 Grey Climbing Brushes for Dolphin offer excellent wall-climbing and scrubbing at a fair price. If you have a generic or less common robot, the Pooloob PF1 Robotic Pool Cleaner Replacement Parts kit provides both brushes and wheel rings for a complete refresh. Either choice will restore your cleaner’s performance and keep your pool sparkling all season.

Frequently Asked Questions
Are aftermarket pool robot brushes as good as OEM?

How often should I replace my pool robot’s brushes?
Inspect brushes every three to six months. Replace them when bristles are frayed, bent, or missing sections. Heavy use, debris, and chemical exposure accelerate wear. Keeping a spare set on hand ensures minimal downtime.
Can I use aftermarket brushes on any robotic pool cleaner?
No, brushes are specific to certain brands and models. Always match the part number or confirm dimensions and mounting design. Many aftermarket listings include compatibility lists, double-check before ordering. For models like Zodiac MX6/MX8, our brush kit guide for saltwater pools covers compatible options.
