Detailed Review

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.

If your cleaner is slipping or failing to climb walls, these rings are a cost-effective fix.

The standout feature is the premium PVA material, which expands when soaked in water. This ensures a tight, secure fit on the rollers and provides excellent grip on pool walls. Real-world use shows that these rings restore the climbing action effectively, allowing the cleaner to scrub waterlines and corners as intended. The installation process is straightforward: just soak the rings for a few minutes until soft, then slide them onto the rollers.

Build quality is solid for an aftermarket part. The PVA is flexible yet durable, and the rings hold their shape after multiple uses. The set includes all four rings needed for a complete replacement, which is convenient. The white color blends in with most cleaners and won't affect aesthetics.

One potential drawback is that compatibility is limited to the models listed, so owners of newer or less common Dolphin models should verify fit before purchasing.

Buying Guide: What to Look for in Dolphin Nautilus Replacement Parts

Choosing the right parts for your Dolphin Nautilus means looking beyond price. Here are the key factors to consider before you buy.

Compatibility with Your Specific Model

Dolphin offers many models, Nautilus, Nautilus CC Plus, Nautilus CC Plus WiFi, M200, M400, M500, and more. Parts like tracks and climbing rings often fit multiple models, but cables and filter panels are model-specific. Always verify your cleaner’s model number against the part’s compatibility list. For instance, the Gearwiz 9995862 cable works only with non-WiFi Nautilus CC Plus and M200, while the Gearwiz 99958821 cable is for the WiFi version. Mixing them up leads to frustration. When in doubt, consult our dolphin pool robot parts page for model-specific guidance.

Material Quality and Durability

Aftermarket parts vary in material quality. Climbing rings made from PVA or heavy-duty rubber last longer than basic plastics. Tracks should be thick, tear-resistant rubber to maintain grip on pool surfaces. Filter panels need sturdy mesh that won’t rip under pressure. The Calvana climbing ring replacement uses quality PVA, and the GVCVHVCV track set features high-grade rubber. OEM parts like the Dolphin Authentic Cartridge Assembly offer guaranteed longevity but at a higher cost. For a balanced option, the Yoursme tune-up kit uses premium-grade materials that resist corrosion and wear.

What’s Included in the Kit

Some parts are sold individually, while others bundle multiple components. A tune-up kit often includes filters, brushes, tracks, and climbing rings, everything needed for a full refresh. The Zymurgoes tune-up kit for the Nautilus CC Plus includes fine and ultra-fine filters, grey brushes, climbing rings, and tracks. The Pokin combo pack offers climbing rings, tracks, guide wheels, and pulley gears. Buying a kit can save money and ensure all worn parts are replaced at once. If you only need one specific item, a single part like the Calvana climbing ring set is a budget-friendly choice.

OEM vs. Aftermarket: Which Is Right for You?

Genuine Maytronics parts (like the Dolphin Authentic Cartridge Assembly) guarantee exact fit and performance, but they cost more. Aftermarket parts from brands like Calvana, Vsttar, and Gearwiz offer significant savings and often match OEM quality. Many aftermarket parts include warranties, Calvana offers a 60-day return policy. For critical components like cables, aftermarket options can be just as reliable if they match specifications. Read reviews and check compatibility carefully. Our article on Essential Dolphin Repair Parts can help you decide.

Final Thoughts

Refreshing your Dolphin Nautilus with the right replacement parts is a smart way to extend its life without breaking the bank. For a complete overhaul, the for CC Plus Tune Up Rebuild Kit with 9991433-R4 from Yoursme covers filters, brushes, tracks, and rings, everything you need in one package. If you just need to restore wall-climbing ability, the The Climbing Ring Replacement from Calvana offers a durable, affordable fix. Whichever route you choose, your pool cleaner will thank you with sparkling results.

Frequently Asked Questions

How often should I replace Dolphin Nautilus parts?

Wear depends on usage and pool conditions. Tracks and climbing rings typically last 1 to 2 seasons. Filter panels should be replaced when they show visible damage or reduced suction. For best performance, inspect your cleaner every few months and replace parts as needed. A tune-up kit is a convenient way to refresh everything at once.

Can I use aftermarket parts on my Dolphin Nautilus CC Plus?

Yes, many aftermarket parts are designed specifically for Dolphin models including the Nautilus CC Plus. Brands like Calvana, Vsttar, and GVCVHVCV offer compatible tracks, rings, wheels, and cables. Just double-check the model compatibility list before purchasing. Aftermarket parts can be a cost-effective alternative to OEM.

What’s the difference between fine and ultra-fine filter panels?

Fine filter panels capture larger debris like leaves and twigs, while ultra-fine filters trap smaller particles such as sand and sediment. Many tune-up kits include both types, allowing you to switch based on your pool’s needs. Using ultra-fine filters improves water clarity but may require more frequent rinsing.

My Dolphin Nautilus isn’t climbing walls anymore. What part should I replace?

Worn climbing rings are the most common cause of poor wall climbing. The 6101611-R4 climbing ring set (available from Calvana and others) is a direct replacement. Also check the tracks, if they’re smooth or cracked, replace them with a 9985006-R2 track set. For more troubleshooting tips, see our guide on Essential Maytronics Dolphin Replacement Parts.
