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.

- IP54 rating adds safety and durability outdoors.
- Includes power cord, saving time and extra cost.
- Heat-resistant design reduces risk of failure.
- 12-month warranty and 30-day money-back guarantee offer peace of mind.
Cons

The E-cowlboy 99956034 replacement power supply is designed for owners of Dolphin robotic pool cleaners who need a reliable, cost-effective alternative to OEM parts. It works with popular models like the Active 10, E10, Solo, Echo, Escape, T15, and Premium 10/20, making it a versatile choice for many pool owners.
Standout features include IP54 waterproofing, which protects against splashes and dust, and a built-in handle for easy carrying. The unit includes the 5898412LF power cord, so you have everything needed for installation. In real-world use, this means less downtime and a straightforward swap of your old unit.
Build quality is solid with an aluminum heat sink and corrosion-resistant components that handle high temperatures and humidity. The upgraded PCB ensures stable current output, which should keep your cleaner running smoothly. However, the power supply is limited to 120W and lacks Wi-Fi, so it won't support app-based models or heavier-duty cleaners.
A potential drawback is the lack of customer reviews, making it hard to gauge long-term performance. Also, the output voltage is under 30V DC, which is safe but may not be suitable for all pool sizes.
Overall, this power supply is a practical, budget-friendly option for Dolphin owners seeking a durable replacement without the OEM price tag. The included warranty and money-back guarantee add confidence. If your cleaner is compatible, it's a smart buy.
Buying Guide: What to Look for in a Pool Cleaner Power Supply Replacement
Compatibility with Your Cleaner Model
The most critical factor is ensuring the power supply matches your specific cleaner. Many Dolphin models use a 4-pin connector, while others use 2-pin or 3-pin. Check your original part number—common ones include 99956034 and 9995672-US-ASSY. The products above cover a wide range, from the For Dolphin Pool Cleaner Power Supply 180W to the 99956034 Power Supply Replacement for Dolphin. For more on compatibility, see our polaris VRX iQ replacement parts.
Power Output and Timer Features
Power output matters for performance. Some units offer 180W for high-efficiency cleaning, while standard models provide 120W. If you want automated cleaning, look for a built-in weekly timer. The 9995672-US-ASSY Power Supply with Weekly Timer lets you schedule daily or every-other-day cycles. This feature saves time and ensures consistent pool maintenance.
Build Quality and Safety
A durable power supply should be waterproof (IP54 rated) and heat-resistant. Look for units with aluminum heat sinks and corrosion-resistant components. The 99956034 for Dolphin Pool Cleaner Power Supply offers IP54 protection and a robust design. These features prevent overheating and extend the unit’s lifespan.
Ease of Installation
Most replacements are plug-and-play—no rewiring needed. Simply disconnect the old unit and connect the new one. Many include a power cord, so you don’t have to reuse an old cable. For cordless models like Aiper, the 16.8V Replacement Charger Compatible with 14.4V is a simple swap. If you’re considering a new cleaner, our best AIPER cordless robotic pool vacuum guide can help.
Final Thoughts
After evaluating all options, we recommend the For Dolphin Pool Cleaner Power Supply 180W for its high power and timer, ideal for larger pools. For budget-conscious owners of basic Dolphin models, the 99956034 Power Supply Replacement for Dolphin offers reliable performance at a lower cost. Both are excellent pool cleaner power supply replacements that will extend the life of your cleaner.
Frequently Asked Questions
How do I know if my pool cleaner power supply needs replacement?
If your cleaner stops working, shows no lights, or runs intermittently, the power supply may be faulty. Check for visible damage or burning smell. Replacing it is often cheaper than buying a new cleaner.
Can I use a third-party power supply for my Dolphin cleaner?
Yes, many third-party units are compatible and often more affordable. Ensure the connector type (4-pin vs 2-pin) matches your model. The options we reviewed are all verified to work with specific Dolphin models. For more on maintaining your cleaner, see our essential Polaris 9650iQ replacement parts guide.
Is it safe to leave the power supply plugged in all the time?
Most units are designed for continuous use, but using a timer can reduce wear. Some models have an on/off switch for convenience. Always follow manufacturer guidelines.
What is the difference between 120W and 180W power supplies?
Higher wattage (180W) provides more power for larger cleaners or heavy debris. Standard 120W is sufficient for most residential pool cleaners. Check your cleaner’s requirements before upgrading.
