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.

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.

If you own a Maytronics Dolphin pool cleaner and notice reduced movement or slipping, worn guide wheels and gears are often the culprit. The ANTOBLE replacement parts kit offers a straightforward fix. It includes four guide wheels and two pulley gears designed to fit a broad range of Dolphin models, from the Nautilus CC Plus to the M500 and beyond.
Standout features include the use of high-quality POM material, which is known for its strength and low friction. This means the parts should resist wear far longer than basic plastic alternatives. In use, the wheels and gears restore smooth tracking and traction, helping your cleaner cover the pool floor efficiently.
Build quality appears solid, with precise dimensions matching original parts. The guide wheels measure about 2.05 inches in diameter and 1.06 inches thick, while the pulley gears are slightly larger. Installation is simple, typically requiring just a screwdriver to swap out old components.
One potential downside is that this kit does not work with the older Nautilus CC model, so check your cleaner's model number before buying. Also, the manual measurement note suggests a possible slight variance, though most users should find a proper fit. As a new product with no reviews yet, long-term durability is unproven but the material choice inspires confidence.

Buying Guide
Check Compatibility with Your Dolphin Model
Not all replacement wheels fit every Dolphin pool cleaner. Before you order, verify the part numbers and model compatibility listed by the manufacturer. For example, the Dolphin Genuine Replacement Part (guide wheels and pulley gears) works with Nautilus CC Plus, Premier, and M400/M500, but explicitly does not fit the Nautilus CC or Nautilus CC Pro. Meanwhile, the The Climbing Ring Replacement from Calvana is compatible with a broader range including M200, DX3, DX4, and DX6. Always cross-reference your robot’s model number with the product listing to avoid returns. For a detailed compatibility chart, see our pool cleaner guide wheel replacement.
Material Quality and Durability
The materials used in replacement wheels directly affect how long they last. ABS plastic (used in the ERETOW 9982275 Inner Wheel Tube Cork) offers excellent wear resistance and can handle the stress of constant pool use without cracking. POM (polyoxymethylene) is another durable choice found in the Pool Cleaner Replacement Parts Guide Wheels from ANTOBLE, providing low friction and long life. For climbing rings, high-density sponge (like in the 9985006-R2 Repair Kit) outperforms traditional foam, maintaining its shape season after season. Choosing quality materials means fewer replacements and better performance.
Kit Contents and Value
Many Dolphin replacement wheel parts come in multi-piece kits that can save you money compared to buying each component separately. For instance, the 3884997-R6 4 Guide Wheels&2 Pulley Gears kit from Vsttar includes four guide wheels and two pulley gears, covering the most common wear items. The 9985006-R2 Repair Kit goes even further by bundling the timing track, climbing rings, and guide wheels with pulley gears. If your robot is showing multiple signs of wear, a comprehensive kit can restore full functionality in one go. Our best robotic pool cleaner wheel kit for 2026 guide can help you compare kit options.
Ease of Installation
Most Dolphin replacement wheels are designed for simple DIY installation with no special tools. The inner tube cork from ERETOW pushes directly into place. Climbing rings from Calvana need to be soaked in water until they expand, then slid onto the rollers. Guide wheels and pulley gears typically snap or screw onto existing mounts. If you’re comfortable with basic maintenance, you can replace these parts in under an hour. For detailed instructions, the The Climbing Ring Replacement listing includes a helpful soaking guide. If you prefer a professional touch, many pool service companies offer installation for a small fee.
Final Thoughts
When it comes to keeping your Dolphin pool cleaner climbing and cleaning at its best, investing in the right replacement wheels makes all the difference. For those who want genuine OEM reliability and a perfect fit, we recommend the Dolphin Genuine Replacement Part guide wheels and pulley gears, which are certified by Maytronics and built to last. If you’re looking for a budget-friendly upgrade that restores traction quickly, the The Climbing Ring Replacement from Calvana offers excellent value with a simple soak-and-install process. Both options will have your robot scaling walls and scrubbing floors like new in no time.

Frequently Asked Questions
How often should I replace Dolphin pool cleaner wheels?
Depending on usage and water chemistry, most wheels and climbing rings need replacement every one to two years. If you notice reduced climbing ability, excessive slipping, or visible wear like cracks or flattened rubber, it is time to swap them out. Regular inspection at the start of each pool season helps catch worn parts early.
Can I use aftermarket wheels on my Dolphin robot?
Yes, many aftermarket brands like ERETOW, Vsttar, and Calvana offer high-quality replacements that are compatible with popular Dolphin models. Just ensure the part numbers and model listings match your specific cleaner. Aftermarket parts often cost less than genuine ones while providing similar durability, making them a smart choice for budget-conscious owners.
What parts are included in a typical Dolphin wheel replacement kit?
Common kits include guide wheels, pulley gears, climbing rings, and sometimes inner tube corks or timing tracks. For example, the 9985006-R2 Repair Kit bundles a timing track, four climbing rings, four guide wheels, and two pulley gears. Buying a kit ensures you replace all worn components at once, saving time and money compared to piecemeal purchases.
How do I install climbing rings on my Dolphin pool cleaner?
Climbing rings require soaking in water for a few minutes until they become soft and pliable. Then slide them onto the roller grooves, making sure they sit evenly. Once dry, they shrink and lock into place. This simple process takes about 15 minutes and restores the robot’s ability to climb walls effectively.
