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.

Buying Guide: Choosing the Right Replacement Power Supply
1. Compatibility with Your Pool Cleaner Model
Not all power supplies work with every robotic pool cleaner. The most critical factor is matching the connector type and voltage. Dolphin cleaners, for example, use different pin configurations: 4-pin, 2-pin, or 3-pin. The wrong connector can damage your robot. Always check your original part number (like 9995672-US-ASSY or 99956034US-ASSY) and compare it with the replacement’s compatibility list. The best pool cleaner replacement battery OEM guide also emphasizes verifying compatibility before purchase.
Many aftermarket units explicitly list which models they support. For instance, the 99956034 power supply works with Dolphin Active 10, E10, Echo, and several others. If you have a Wi-Fi enabled model, you need a power supply that supports that feature. Non-Wi-Fi units will not connect to your app.
2. Power Output: 120W vs. 180W
Robotic pool cleaners require a specific wattage to run efficiently. Most basic models use 120W, while higher-end or older units may need 180W. Using a lower wattage supply can cause sluggish cleaning or overheating. Check your original power supply label or manual. For example, the 180W unit from E-cowlboy is designed for Dolphin 4-pin models like Nautilus CC Plus and DX3, while sixcow’s 99956034 replacement delivers 120W for basic on/off cleaners. Getting the right wattage ensures your robot operates at peak performance without risking damage.
3. Build Quality and Durability
Pool environments are tough: moisture, heat, and UV exposure can degrade electronics. A good replacement should have an IP54 rating (splash-proof) and a corrosion-resistant enclosure. Look for units with aluminum heat sinks to dissipate heat and prevent overheating. Brands like Hihitomorrow and E-cowlboy use high-quality PCB boards and thermal protection switches. The best robotic pool cleaner spare parts OEM article highlights that robust materials extend the life of your replacement part.
4. Extra Features: Timer, On/Off Switch, and Included Cables
Some power supplies come with a built-in weekly timer, allowing you to schedule cleaning cycles automatically. Others include a power cord, saving you from reusing a worn-out cable. An on/off switch is handy for quick power cuts without unplugging. For example, the 180W E-cowlboy unit includes both a timer and a switch, plus a new power cord. If you prefer simplicity, a basic 120W unit without timer may suffice. Consider what features matter most for your routine.

Final Thoughts
Choosing the right replacement power supply for your pool cleaner comes down to matching your model and preferences. For owners of Dolphin 4-pin models who want extra convenience, the For Dolphin Pool Cleaner Power Supply 180W delivers a timer, switch, and solid 180W output. If you have a basic on/off model and value a genuine OEM fit, the Dolphin Genuine Replacement Part offers certified quality for Wi-Fi models like the M400 or Nautilus CC Supreme. Both options are reliable choices to restore your robot’s cleaning power without breaking the bank.
Frequently Asked Questions
Can I use a non-OEM power supply for my Dolphin pool cleaner?
Yes, many aftermarket units are compatible and often more affordable. However, ensure they meet the same electrical specifications and have the correct connector. Brands like E-cowlboy and Hihitomorrow offer replacements that match OEM part numbers and are made with quality materials. Check the compatibility list carefully before ordering.
How do I know which replacement power supply is compatible with my cleaner?
Look at the original power supply label for a model or part number (e.g., 99956034, 9995672). Then compare it to the replacement’s list of supported models. Also verify the pin configuration: 4-pin, 2-pin, or 3-pin. If you have a Wi-Fi model, you need a power supply that supports that feature. Our best robotic pool cleaner replacement parts OEM guide includes tips on identifying compatible parts.
Is a 120W power supply enough for my pool cleaner?
It depends on your model. Many basic Dolphin cleaners (Active 10, E10, Echo) use 120W. If your original unit is 120W, a replacement with the same rating is fine. Upgrading to 180W when not needed is safe, but the cleaner will only draw what it requires. For older or larger cleaners that originally used 180W, a 120W supply may cause poor performance. Always match the wattage to your robot’s requirements.
Can I install a replacement power supply myself?
Yes, most replacements are plug-and-play. You simply unplug the old unit and connect the new one. No wiring or tools are required. Just ensure the power is off before swapping. The included power cord, if provided, makes the process even simpler. Follow the manufacturer’s instructions for a safe installation.
