If you own a Dolphin robotic pool cleaner, you already know that brushes are the unsung heroes of a sparkling pool. Over time, those bristles wear down, and your cleaner starts struggling on walls or leaves debris behind. You might be facing a choice between the newer PVC climbing brushes and the classic Wonder brushes. This guide breaks down the differences between these replacement options, focusing on four top-rated products from brands like MAYTRONICS, Pokin, Dolphin, and XZFYSM. Whether you prioritize aggressive wall climbing or gentle yet thorough scrubbing, we will help you find the right set.
Before we dive into the specifics, it helps to understand the broader landscape. For a deeper look at how these brushes compare to other types, see our dolphin active brush vs standard brush.

- Intelligent navigation and obstacle avoidance ensure thorough coverage of complex pool shapes.
- Strong suction and dual brushes effectively clean floors, walls, and waterline.
- Durable build with high safety certifications and IP68 water resistance.
- Easy recharging with a dedicated cordless dock.
Cons
- Heavy at 27 pounds, which may be cumbersome to lift out of the pool.

The Beatbot AquaSense is a 2026 upgrade to the cordless robotic pool cleaner lineup, designed for both above-ground and in-ground pools up to 2,260 square feet. It aims to deliver a hands-free cleaning experience with advanced AI and powerful suction, making it suitable for homeowners who want to maintain a pristine pool without manual effort.
Standout features include the intelligent path optimization algorithm driven by a quad-core 1.8GHz CPU and 15 sensors, which maps the pool and avoids obstacles in real time. The 5500 GPH suction from a 200W brushless motor allows it to climb walls, including curved surfaces, and capture fine debris down to 150 microns. The dual-brush system with front and rear rollers doubles cleaning efficiency compared to single-brush designs.
Design and build quality are robust: the AquaSense weighs 27 pounds and has an IP68 rating, ensuring it can handle submersion and harsh pool chemicals. The cordless design eliminates the hassle of floating cables, and the charging dock is also cordless for easy recharging. Safety certifications like ETL and CEC add to its reliability.
Potential drawbacks include its weight, which may make lifting the unit out of the pool a bit of a workout. The battery life, while rated at up to 3 hours on floors, could be shorter in practice with heavy suction or wall climbing. Additionally, the price point is high compared to basic pool cleaners, but the included 2-year full machine replacement warranty offers good value.
Overall, the Beatbot AquaSense is a capable, intelligent pool vacuum that excels at cleaning all surfaces. For pool owners who prioritize convenience and thorough cleaning, it is a strong investment. The combination of smart navigation, powerful suction, and cordless freedom makes it a top contender in the premium robotic pool cleaner market.
Buying Guide: Choosing Between PVC and Wonder Brushes
Brush Material and Construction
The most noticeable difference is the material. The Dolphin Genuine Replacement Part (blue climbing brushes) are made from rigid PVC, designed to dig into algae and stubborn dirt on walls. In contrast, the standard grey brushes (like the Dolphin Genuine Replacement Part 6101641-R2) typically use a softer, more flexible nylon material that is gentler on vinyl liners and fiberglass surfaces.
Hard PVC bristles excel at scrubbing, but they can be too aggressive for delicate pool finishes. If you have a concrete or gunite pool, the PVC brushes will shine. For vinyl or painted surfaces, the softer Wonder brushes are a safer choice.
Compatibility with Dolphin Models
Not every brush fits every Dolphin model. The blue climbing brushes (6101660-R2) are compatible with commercial models like the 2×2, Heavy Duty, and 3001. The grey brushes (6101641-R2) are standard for residential units such as the Nautilus Plus, Premier, and many others. Always verify your cleaner’s model before purchasing. The aftermarket options like the Pokin 6101641-R2 set offer broad compatibility across dozens of Dolphin and Prowler models, which can be a deciding factor for owners with older machines.

Climbing Performance vs. Gentle Cleaning
The PVC climbing brushes are specifically engineered for traction. Their stiff bristles help your Dolphin grip and climb vertical surfaces, making them ideal for pools with heavy algae buildup or textured walls. The Wonder brushes, on the other hand, provide a balanced cleaning action that reduces wear on the cleaner’s motor and leaves a finer finish on floor and walls.
If your pool sees regular use and you value efficiency over brute force, the softer brushes are perfectly adequate. But if you frequently battle stubborn calcium deposits or black algae, upgrading to the PVC set could save you time and manual scrubbing.

Also consider the aftermarket alternative from XZFYSM, which offers a grey brush replacement designed to mimic the OEM feel at a lower cost. While not as aggressive as the PVC option, it can be a reliable budget-friendly choice for routine maintenance.
Final Thoughts
The best brush set depends entirely on your pool’s surface and your cleaning priorities. For owners of commercial or heavily soiled pools who need maximum wall-climbing power, the Dolphin Genuine Replacement Part blue climbing brushes are the clear winner. If you run a residential Dolphin and prefer a gentle yet effective clean that protects your liner, the Dolphin Genuine Replacement Part grey brushes deliver reliable performance and broad compatibility. Both sets are backed by strong user ratings and proven durability, so you can shop with confidence.

Frequently Asked Questions
Are PVC climbing brushes better than standard Wonder brushes for my Dolphin?
Not necessarily. PVC brushes provide superior scrubbing and wall climbing, especially on concrete or gunite pools. However, for vinyl or fiberglass surfaces, the softer Wonder brushes are gentler and prevent scratching. Choose based on your pool’s finish and the level of buildup you deal with.
How do I know which replacement brush fits my Dolphin model?
Check your cleaner’s model number and compare it to the compatibility lists provided by each manufacturer. The blue climbing brushes (6101660-R2) fit commercial models, while the grey brushes (6101641-R2) fit most residential models like the Dolphin Nautilus Plus, Premier, and Quest. If you are unsure, our dolphin OEM vs aftermarket brushes guide offers detailed model charts.
How often should I replace the brushes on my Dolphin pool cleaner?
As a rule of thumb, inspect your brushes every 2026 and replace them when you notice reduced climbing ability, visible wear, or bent bristles. In heavy-use pools, a seasonal replacement is common. Soft brushes tend to wear faster than PVC ones.
Can I mix PVC and Wonder brushes on the same cleaner?
It is possible but not recommended, as it can create uneven cleaning patterns and strain the cleaner’s drive system. Stick to matching pairs for balanced performance and long life.
