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.

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.

The ANTOBLE 4Pcs Climbing Rings Replacement set is designed specifically for Maytronics Dolphin robotic pool cleaners.

This part (9991460-R1) is ideal for pool owners seeking an affordable, high-performance alternative to the original filter. It is especially suited for those who want to improve water clarity by trapping fine particles without sacrificing cleaning efficiency.
The standout feature of this basket is its microfiltration technology, which captures small debris while allowing larger particles to pass through.

Buying Guide
Compatibility with Your Dolphin Model
Before buying any replacement part, confirm it matches your specific Dolphin Nautilus model. Parts like tracks and climbing rings often fit multiple models, but filters and cables are more model-specific. For example, the cable for Nautilus CC Plus (Non-WiFi) will not work with the WiFi version. Always check the product description for a compatibility list.
Using the wrong part can lead to poor performance or even damage. When in doubt, look for parts that explicitly list your model number, like Nautilus CC Plus or M200. If you need help with other models, see our best pool cleaner replacement tracks for polaris guide.
Material Quality and Durability
Quality matters when replacing parts. Rubber tracks should be thick and flexible, not brittle. Climbing rings made from PVA foam need to be soft after soaking, not hard and cracked. Filter cartridges with heavy-duty ABS plastic frames last longer and resist breaking under water pressure. Genuine Dolphin parts, like the motor unit, offer certified reliability, while aftermarket options from brands like Calvana and Funmit provide excellent value without sacrificing performance.
Ease of Installation
Most replacement parts are designed for simple DIY installation. Tracks snap into place, climbing rings slide onto rollers after soaking, and filter panels clip into the housing. No special tools are needed. However, for more complex parts like the motor unit or cable, you may want to watch a tutorial or consult the manual. If you are not comfortable, a professional can help, but most users find it straightforward. For protecting your robot when not in use, consider a universal pool robot cover.
Value for Money
Replacement parts vary widely in cost, from under twenty dollars for climbing rings to over a hundred for a new cable. Consider the lifespan of the part and how often you use your cleaner. A tune-up kit that includes multiple components can save money compared to buying each piece separately. Also, look for warranties or satisfaction guarantees, which indicate confidence in the product. Balancing price with durability ensures you get the best long-term value.
Final Thoughts
Keeping your Dolphin Nautilus in top shape is easy with the right parts. For essential traction and grip, the Calvana (2 Pack) Replacement Gray Tracks offer factory-quality performance at an affordable price, while the for CC Plus Tune Up Rebuild Kit with 9991433-R4 provides a complete refresh with filters, brushes, tracks, and rings for comprehensive maintenance. Choose based on your specific needs, and your pool will stay sparkling clean all season.

Frequently Asked Questions
How often should I replace the tracks on my Dolphin Nautilus?
Check tracks every season. If they show signs of wear, like cracks, stiffness, or reduced grip on walls, replace them. With regular use, tracks typically last one to two years, but this depends on pool conditions and usage frequency.
Can I use aftermarket parts on my Dolphin Nautilus?
Yes, many aftermarket parts are compatible and perform well. Brands like Calvana and Funmit offer high-quality alternatives at lower prices than OEM parts. Just ensure the part number matches your model, such as 9985006-R2 for tracks or 9991432-R4 for filters.
How do I install climbing rings on my Dolphin Nautilus?
Soak the climbing rings in water until they soften and expand. Then slide them onto the roller pins, ensuring they sit evenly. This process is simple and usually takes just a few minutes. If the rings are dry and hard, soaking is essential for proper installation.
What is the difference between fine and ultra-fine filter panels?
Fine filter panels capture larger debris like leaves and hair, while ultra-fine panels trap smaller particles such as sand and sediment. Many tune-up kits include both, allowing you to switch based on your pool’s needs. For best results, use ultra-fine filters for crystal-clear water in 2026.
