- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons

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 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.
Buying Guide: What to Look for in Dolphin Replacement Parts
Compatibility with Your Dolphin Model
Not all parts fit every Dolphin model. Before purchasing, verify that the replacement part matches your specific cleaner series, such as Nautilus CC, Active, or M-series. Many aftermarket parts, like the Ulticor Ultra Fine Filter Basket Compatible, list dozens of compatible models, but always double-check your model number. For example, the Ulticor basket explicitly states it is not compatible with Nautilus CC Pro or Supreme. A mismatched part can cause poor fit or even damage your cleaner.

Filtration Efficiency and Debris Capture
The filter basket or cartridge is the heart of your cleaner’s debris collection. Ultra-fine filter panels, like those in the Ulticor Ultra Fine Filter Basket Compatible, capture microscopic particles such as pollen and sand. For bag-style models, conversion kits like the 9991414-R1 for Dolphin Pool Cleaner Cartridge upgrade to cartridge filtration, which is easier to clean and provides better water clarity. If you have a Nautilus CC Plus, the for CC Plus Tune Up Rebuild Kit with 9991433-R4 includes both fine and ultra-fine filter panels for complete coverage.
Traction and Climbing Performance
Tracks and climbing rings directly affect how well your cleaner navigates walls and stairs. Worn tracks cause slipping and missed spots. The Calvana (2 Pack) Replacement Gray Tracks are made of high-quality rubber that grips pool surfaces firmly. Climbing rings, such as the 4Pcs Climbing Rings Replacement for Maytronics from ANTOBLE, provide the extra lift needed to climb over obstacles. Soak them in water before installation to restore their flexibility.

Build Quality and Durability
Pool chemicals and sunlight can degrade cheap parts quickly. Look for replacement parts made from corrosion-resistant materials. The Pool Cleaner Rear Brushe Replacement Parts from LBLVBNEWD use high-toughness elastic material that resists cracking and deformation. Genuine Dolphin parts, like the Genuine Dolphin Replacement Part motor unit, carry the Maytronics certification for guaranteed durability. While aftermarket options often save money, they must match OEM quality to avoid frequent replacements.
