Buying Guide for Dolphin Climbing Brushes
Compatibility with Your Dolphin Model
Not all climbing brushes fit every Dolphin robot. The part number 6101641-R2 is common across many models, but always double check your cleaner’s manual or existing brush part. For example, the Dolphin Automatic Robotic Pool Vacuum Cleaner uses a specific brush set that may differ from later models. Third-party brushes often list broad compatibility, but we recommend verifying your model before purchasing. Refer to our best pool robot traction brush guide for additional cross reference tips.
Brush Material and Design
Climbing brushes come in two main types: grey combination brushes (which scrub and climb) and dynamic rear brushes that provide stability. The grey brushes are softer on pool surfaces but still aggressive enough to remove dirt. Some aftermarket brushes use stiffer nylon for longer life, while OEM Dolphin parts balance wear and surface safety. For vinyl or fiberglass pools, softer brushes are safer; for concrete, you can opt for firmer bristles.
Ease of Installation
Most Dolphin climbing brushes snap or screw into place without tools. The genuine Dolphin set and most compatible replacements are designed for quick swap outs. However, some brushes like the Doule King rear dynamic brush include a screwdriver for secure mounting. If you prefer minimal fuss, stick with pop in designs. Always check if the brush comes as a pair or single, as some models require both front and rear replacements.
Durability and Longevity
Brush lifespan depends on pool usage, water chemistry, and surface type. Genuine Dolphin brushes often last longer due to quality control, but many third party brands use reinforced materials. The Brush Climbing Parts 2 Pack Replacement from Sharutia has reported strong durability in routine use. On average, replace climbing brushes every season or after 500 cycles. Worn brushes not only reduce cleaning but can also strain the robot’s motor.
Final Thoughts
After reviewing six climbing brush options, we recommend two picks for different needs. For owners who want guaranteed fit and OEM performance, the Dolphin Genuine Replacement Part offers reliable traction and scrubbing at a fair price. If you prefer a value oriented set that still delivers strong wall climbing, the Brush Climbing Parts 2 Pack Replacement from Sharutia is a solid choice with broad compatibility. Whichever you choose, replacing worn brushes will restore your Dolphin’s ability to scale walls and keep your pool sparkling through the season.

How do I know if my climbing brushes are worn?
