Pros
- Wide compatibility with many Dolphin models
- Made from durable, expandable PVA material
- Easy to install with just water soaking

The Calvana climbing ring replacement set is designed for owners of Maytronics Dolphin robotic pool cleaners who need to restore their unit's wall-climbing performance. It is compatible with popular models like the M200, M400, M500, Nautilus, Nautilus CC Plus, DX3, DX4, DX6, and many others. 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. Additionally, the rings require a brief soaking before installation, which adds a small step compared to some other replacement parts. However, this is a minor inconvenience given the cost savings over OEM parts.
Overall, the Calvana climbing ring replacement offers excellent value for Dolphin pool cleaner owners. It is easy to install, restores climbing performance effectively, and comes with a 60-day satisfaction guarantee. For routine maintenance, this is a smart buy that can extend the life of your cleaner without breaking the bank.

How to Choose the Right Replacement Parts
Before buying any replacement part, you need to know your pool robot’s exact model and the part that’s failing. Check your owner’s manual or look for a model number on the robot itself. Then, consider these key factors:
- Compatibility: Always verify that the part is designed for your specific robot model. Using the wrong part can cause further damage.
- Material Quality: Look for parts made from durable, corrosion-resistant materials that can withstand pool chemicals and sun exposure.
- Warranty: A good warranty gives you peace of mind. Many manufacturers offer at least a 60-day return policy, and some offer longer coverage.
- Ease of Installation: Some parts are easy to swap in yourself, while others may require professional help. Check if the part comes with instructions.
For example, if your Polaris cleaner is stuck, a backup valve replacement like the MAKHOON Upgraded G52 Backup Valve Replacement can solve the issue. If your Dolphin robot’s cable is frayed, a replacement cable such as the Gearwiz 9995862-60ft Blue Cable Only Compatible is a straightforward fix.
Frequently Asked Questions
How often should I replace my pool robot’s backup valve?
Most backup valves last one to two seasons, depending on usage and water conditions. If you notice your Polaris cleaner getting stuck frequently, it’s time to inspect the valve.
Can I use a third-party cable for my Dolphin pool robot?
Yes, many third-party cables are compatible and work well. Just make sure the cable is specifically designed for your model, such as the Nautilus CC Plus (Non-WiFi) vs. WiFi versions, as they use different connectors.
How do I know if my pool robot’s tracks need replacing?
If your robot is slipping, not climbing walls, or leaving streaks, worn tracks are a common culprit. Check for cracks, smooth spots, or missing treads.
Is it worth repairing my pool robot instead of buying a new one?
In many cases, yes. Replacing a single part like a valve or cable is much cheaper than a new robot. If your robot is otherwise in good condition, a simple repair can extend its life for years.
