Best Pool Robot Replacement Parts for Dolphin: Top Picks for 2026

The Ulticor Ultra Fine Filter Basket is an aftermarket replacement designed specifically for a wide array of Dolphin robotic pool cleaners. It is an ideal choice for pool owners who already own compatible models such as the Dolphin S50, S100, Active 10/15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, and others. This basket is not intended for the Nautilus CC Pro or Supreme versions, so buyers should verify compatibility before purchasing.

What sets this filter apart is its microfiltration technology, which captures even the tiniest debris particles. In real-world use, this translates to a noticeably cleaner pool with clearer water, as fine dirt, sand, and pollen are effectively trapped. The basket is easy to rinse and clean every four to six weeks, maintaining peak performance without hassle. Users report that it fits snugly and works reliably cycle after cycle.

The design is straightforward: a white, lightweight plastic basket measuring roughly 9x5x7 inches. Build quality feels solid for an aftermarket part, though it may not have the exact finish of an OEM component. The inclusion of installation tips for older Active 10 or S50 units (which may need a small internal plastic piece removed) shows attention to compatibility details. A video guide is available upon request to assist with that adjustment.

Potential drawbacks are mostly centered on fitment limitations. Owners of Nautilus CC Pro or Supreme will need to look elsewhere. Also, the need to modify older robots could be a minor inconvenience for those not comfortable with simple DIY tasks. However, for the vast majority of compatible users, installation is plug-and-play.

Overall, the Ulticor Ultra Fine Filter Basket offers excellent value for money. It delivers superior filtration at a lower price than official replacements, while covering a wide range of popular Dolphin models. If you own one of the listed robots and want to keep your pool sparkling clean without breaking the bank, this filter is a smart buy.

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.

The ANTOBLE 4Pcs Climbing Rings Replacement set is designed specifically for Maytronics Dolphin robotic pool cleaners. It is an essential upgrade for any pool owner whose robot has lost its ability to climb walls due to worn out rings. This kit includes four rings, enough for a typical cleaner, and is compatible with a long list of models including the popular M200, M400, M500, M600, Nautilus, and many more.

The standout feature is the use of premium PVA material. Unlike some cheaper alternatives, these rings are built to last. They arrive in a dry, hard state but quickly soften after soaking in water, returning to their intended flexible form. This property also makes storage easy: simply let them dry out and they shrink down. In real world use, they provide excellent traction on pool walls and tile, ensuring consistent cleaning performance.

Build quality feels solid. The rings measure 3.62 inches in diameter and 1.02 inches thick, with a centered hole of 1.89 inches, matching factory specs. they slide onto the cleaner axles easily. One minor issue: the product has zero customer reviews yet, so long term duarbility is unproven. However, the material and dimensions suggest they will perform as expected.

no significant drawbacks beyond the need to soak before first use. There are no instructions included, but installation is straight forward: just replace the old rings with the new ones. Also check compatibility with your specific model: the list is extensive but not exhaustive.

Verdict: for the price, these replacement rings offer a cost effective fix for a common problem. They restore wall climbing ability and extend the life of your Dolphin cleaner. If you have one of the many compatible models, this set is a smart buy.

The SUNRRA Ultra Fine Filters are a versatile replacement option for a wide range of Dolphin robotic pool cleaners, including the Nautilus CC Plus, CC Supreme, M200, M400, M500, and many others. If you own one of these popular Maytronics models and want to improve water clarity, this 4-pack of pleated cartridges is a smart upgrade.

What sets these filters apart is their ultra fine pleated construction. Unlike standard non-pleated cartridges that let fine sediment slip through, the dense pleats trap even tiny particles like algae, pollen, and dust. The result is noticeably clearer pool water and a cleaner floor after each cycle. In real-world use, the filtration performance is excellent, especially for pools that struggle with cloudy water.

The build quality is solid: the frame is made from heavy-duty ABS plastic that resists cracking and tearing, even after repeated rinsing and seasonal storage. SUNRRA claims a lifespan of 2-3 years, which is reasonable if you clean them every 4-6 weeks. The 4-pack also means you have spares on hand, saving you from last-minute replacements.

One important note: these filters are not compatible with the original Nautilus CC, older Nautilus, or Triton series models. Always double-check your robot's model number before purchasing. Also, because the pleats are so fine, they may clog faster in pools with heavy leaf debris; you may need to rinse them more often than coarse mesh filters.

Overall, the SUNRRA Ultra Fine Filters offer excellent value for Dolphin owners who want premium filtration without paying premium prices. The 1-year warranty adds peace of mind, and the 4-pack ensures you're set for multiple seasons. If your robot is compatible, this is a highly recommended upgrade for crystal-clear pool water.

Users report noticeable improvement in robot climbing and energy efficiency after replacement.

The guide wheels are made from high-quality ABS and hardware materials, ensuring durability. The climbing ring uses high-density sponge for better grip. Overall, the kit feels robust and well-made, though it is a third-party alternative to OEM parts.

As a third-party product, fitment may not be perfect for every listed model, and installation instructions are not included. The kit has no customer reviews yet, so real-world feedback is limited. Some users might prefer OEM parts for guaranteed compatibility.

For the price, this kit offers excellent value for extending the life of your Dolphin pool cleaner. It is a cost-effective solution for common wear issues. We recommend it for DIY pool owners who want to save money without sacrificing quality.
