The GVCVHVCV 9985006-R2 Track & Ring replacement kit is designed for owners of Dolphin robotic pool cleaners, specifically models like the Nautilus CC Plus. If your cleaner has been moving slowly, losing traction on the pool floor, or failing to climb walls, worn tracks and climbing rings are likely the culprit. This kit offers a direct replacement to restore your cleaner's original performance.
The standout feature is its comprehensive nature: you get two timing tracks (part 9985006-R2) and four climbing rings (part 6101611-R4). This covers the most common wear points. In real-world use, users report that after installation, the cleaner regains its ability to climb walls efficiently and moves at full speed across the pool floor. The tracks provide the necessary grip, while the rings help the cleaner scale walls and overcome obstacles.
Build quality is solid. The tracks are made from a durable rubber-like material that resists stretching and tearing. The climbing rings are flexible once softened, but they can arrive dry and hard due to packaging. The manufacturer advises soaking them in water to restore pliability, which works well. Overall, the materials feel comparable to OEM parts.
A potential drawback is the need to soak the rings before installation, which adds a small step. Also, compatibility is not universal; while it fits many Dolphin models, double-check your specific model number before purchasing. The kit does not include installation instructions, but replacement is straightforward for anyone who has removed the old parts.
Overall, this replacement kit is an excellent value. It breathes new life into a sluggish pool cleaner at a fraction of the cost of a new unit. If you own a compatible Dolphin model and notice performance issues, this kit is a smart, cost-effective fix.

Buying Guide for Dolphin Nautilus Replacement Tracks
Compatibility with Your Dolphin Model
Not all tracks fit every Dolphin Nautilus variant. The older Nautilus and Nautilus CC Plus use part number 9985006-R2, while newer models like the Nautilus CC and Nautilus Pro require different tracks. Always check your cleaner’s model number before ordering. Many aftermarket kits list compatible models, but double-checking ensures a proper fit. For a detailed compatibility list, see our 5 top replacement tracks for pool robot in 2026.
Material Quality and Durability
OEM tracks from Dolphin use high-grade rubber that resists aging and cracking. Aftermarket options vary: some use dense sponge for climbing rings and reinforced plastic for timing tracks. Look for tracks made from UV-stabilized materials to withstand pool chemicals and sunlight. Softer rings may need a water soak before installation to become pliable.
What’s Included in the Kit
Some replacement kits include only the two timing tracks (9985006-R2), while combo packs add climbing rings, guide wheels, and pulley gears. If your climbing rings are also worn, a full kit saves money and time. For example, the Pokin combo delivers four rings, two tracks, and four wheels. Evaluate your current parts to decide whether you need a basic track set or a complete refresh.
Ease of Installation
Replacing tracks is a straightforward DIY task. Most kits require only a screwdriver to remove the old tracks and snap on the new ones. Climbing rings slip over the wheels. No special tools are needed. If you are unsure, watch a few online tutorials. For more tips on track maintenance, read our best pool robot track belt replacements.
Final Thoughts
Restoring your Dolphin Nautilus to peak performance comes down to choosing the right replacement tracks. For a budget-friendly option that covers all wear points, the Pool Cleaner Accessories Combo Replacement Kit from Pokin offers exceptional value with climbing rings, tracks, and wheels. If you prefer genuine OEM reliability, the Dolphin Grey Track Pack of 2 for Nautilus CC ensures a perfect fit and long-lasting traction. Either way, your pool cleaner will climb walls and scrub efficiently again.

Frequently Asked Questions
How do I know when my Dolphin Nautilus tracks need replacing?
Signs include slow movement, difficulty climbing walls, visible cracks or stretching in the rubber, and the cleaner leaving debris behind. If your Nautilus is more than two years old, inspect the tracks regularly. Replacing them early prevents further strain on the motor.
Are aftermarket tracks as good as OEM?
Many aftermarket tracks, like those from PROSOCOOL and GVCVHVCV, use high-quality materials that match OEM performance. They often cost less and include extra parts. However, OEM Dolphin tracks are certified genuine and guarantee exact fitment. For most users, aftermarket options provide excellent value in 2026.
Can I replace just the tracks or do I need climbing rings too?
If your cleaner is still climbing but moving slowly, new tracks alone may suffice. But if it slips on walls, the climbing rings are likely worn. Since rings are inexpensive and often included in combo kits, it is wise to replace both at the same time. For more on this topic, see our robotic pool cleaner track belt.
What models are compatible with 9985006-R2 tracks?
The 9985006-R2 timing track fits Dolphin Nautilus (old model), Nautilus CC Plus, Apollo, Apollo Plus, DX3, DX6, M400, M500, Premier, and several others. It does not fit the Nautilus CC, Nautilus Pro, or Triton PS series. Always verify your model against the product description before purchasing.
