Pros
- High-efficiency microfiltration captures fine dirt, sand, and leaves for pristine pool water.
- Works with a wide range of popular Dolphin robot models, reducing the need for multiple filter types.
- Easy to clean and maintain with no special tools required.
- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons
- Not compatible with Dolphin Nautilus CC Pro or CC Supreme models, limiting its use for newer variants.
- Older versions of Active 10 or S50 may require removal of a plastic piece for proper fit, which could be inconvenient for some users.
- As an aftermarket part, it may not perfectly match OEM quality or warranty coverage.
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.
Pros
- Plug-and-play installation with no rewiring needed
- Broad compatibility with many Dolphin and Maytronics models
- Includes a long 50-foot power cord for flexible outlet placement
- Durable build with IP54 waterproof rating and thermal protection
- Restores cleaning performance of existing robotic pool cleaners
Cons
- Only compatible with manual on/off Dolphin models (no WiFi or smart features)
- Aftermarket brand (Sixcow) may not match OEM build quality over time
- No customer reviews yet, so long-term reliability is unverified
The Sixcow 99956034 Power Supply Replacement is a practical solution for owners of Dolphin robotic pool cleaners that use a basic manual on/off switch. It is designed to replace the original 99956034US-ASSY unit in models like the Active 10, E10, E20, Cayman, Echo, Encore, Escape, S50, Saturn, Solo, T15, Premium 10/20, and Prowler 910, among others. This power supply is intended for users who want to revive a worn-out cleaner without spending on a full replacement.
Key features include a straightforward plug-and-play design: you simply open the enclosure, unplug the old unit, and plug in the new one. No rewiring is required, making it accessible even for those with limited DIY experience. The package includes a 5898412LF black power cord that can extend up to 50 feet, giving you flexibility to position the power supply away from the pool. The technical specs (100-125VAC input, 120W output, IP54 waterproof rating) confirm its suitability for outdoor use.
Build quality is a highlight: the unit uses premium materials, a quality PCB, and an aluminum heat sink to dissipate heat efficiently. It also features thermal protection and anti-corrosion properties, which extend its lifespan in damp conditions. The included handle adds convenience for moving or hanging the unit. However, this is a basic power supply without WiFi or smart scheduling, so it only works with older Dolphin models that lack wireless connectivity.
Potential drawbacks are few but worth noting. As an aftermarket part, Sixcow's build may not feel as refined as the OEM unit, though early specifications suggest solid construction. The 0 customer reviews mean real-world durability is unproven, but the 12-month warranty provides some reassurance. Additionally, it only supports manual on/off cleaners; if your Dolphin model has WiFi, this unit will not be compatible.
Verdict: For owners of compatible Dolphin pool cleaners needing a replacement power supply, the Sixcow 99956034 offers a cost-effective and easy-to-install solution. Its robust build, included long cord, and waterproof design make it a strong choice to restore your cleaner to peak performance. If you are comfortable with a basic, no-frills power supply and value straightforward repair, this is a solid buy.

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.

The Fiitzn Ultra Fine Filtration Basket is a replacement filter designed for a wide range of Dolphin robotic pool cleaners, including models like the S50, Active 15, Echo, Nautilus CC, Encore, E10, E20, Proteus DX3, Solo, and Advantage. 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. This design prevents the filter from clogging quickly, ensuring consistent suction and longer cleaning cycles. In real-world use, this means less downtime for rinsing and more effective pool maintenance, even in dirty conditions. The basket maintains strong performance over weeks of use before needing a quick rinse.
Build quality is solid thanks to the ABS plastic frame, which resists cracking and deformation under pressure. The filter layer is securely supported, reducing the risk of tearing during operation. Installation is straightforward: it fits exactly like the original part, so no modifications or adapters are needed. Rinsing every 4-6 weeks keeps it working optimally, and with proper care, the basket can last 2-3 years, offering excellent value.
One potential drawback is that in extremely dirty pools, the filter may need more frequent rinsing to maintain flow. Additionally, the package includes only one basket, so owners of larger pools might need to buy a second.

It is a smart upgrade or replacement for Dolphin pool cleaner owners who want to keep their water crystal clear without breaking the bank.

Buying Guide: What to Look for in Dolphin Spare Parts
Compatibility with Your Dolphin Model
Not all parts fit every Dolphin cleaner. Before purchasing, verify that the part number matches your model. Many aftermarket parts list compatible series like Active, Nautilus, or Proteus. For example, the Calvana (2 Pack) Replacement Gray Tracks fit a wide range of Dolphin cleaners, including Active, Cayman, and Echo. Always double-check the model list in the product description to avoid mismatches.
For power supplies, ensure the voltage and connector type align. The 99956034 Power Supply Replacement for Dolphin is compatible with manual on/off models without WiFi. If you need a universal power solution, see our best universal power supply picks.
Filtration Quality and Debris Capture
The filter basket is the heart of your cleaner’s debris collection. Ultra-fine mesh captures pollen, algae, and fine dust, while standard baskets handle larger debris. The Ulticor Ultra Fine Filter Basket Compatible uses microfiltration technology to trap particles as small as sand, keeping your pool water exceptionally clear. For a similar option, the Fiitzn Ultra Fine Filtration Basket Compatible offers a spring-loaded design that prevents clogging in very dirty pools.
If you prefer cartridge-style filtration, the 9991414-R1 for Dolphin Pool Cleaner Cartridge conversion kit upgrades bag-style systems to easier-to-clean cartridges. This is a great option for older Dolphin models like the Deluxe 4 or Discovery.
Durability and Material Quality
Replacement parts must withstand constant water exposure, UV rays, and abrasive debris. Look for materials like high-quality rubber for tracks, PVA foam for climbing rings, and ABS plastic for filter frames. The Calvana Climbing Ring Replacement is made from durable PVA and comes as a set of four rings, ensuring consistent wall climbing. Similarly, the ANTOBLE 4Pcs Climbing Rings offer a cost-effective alternative with the same PVA construction.
For tracks, the Calvana gray tracks are made from thick rubber that grips pool walls effectively. If you need a genuine OEM part, the Dolphin Genuine Replacement Part, Active Front Grey Brush is certified by Maytronics and built to last. For more on traction components, read our best traction brush guide.
Ease of Installation and Maintenance
Most replacement parts are designed for simple DIY installation. Filter baskets and cartridges typically snap into place without tools. Climbing rings need to be soaked in water before installation to expand and soften. The 99956034 Power Supply features plug-and-play wiring, so you can swap it in minutes. For wheel and track replacements, check our universal wheel replacement guide for tips.
Regular maintenance extends part life. Rinse filter baskets every 4 to 6 weeks and inspect climbing rings for wear. For brushes, the Dolphin Genuine Replacement Brush should be replaced when bristles are frayed. If your cleaner struggles with wall climbing, see our best wall climbing brush recommendations.
Final Thoughts
Choosing the right spare parts for your Dolphin robotic pool cleaner ensures efficient cleaning and extends the life of your investment. For most users, the Ulticor Ultra Fine Filter Basket Compatible offers outstanding filtration at a reasonable price, while the Calvana (2 Pack) Replacement Gray Tracks provide durable traction for models with worn rubber. Whether you need a quick fix or a full overhaul, these parts will have your cleaner back in action in no time.
