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.

Buying Guide for Robotic Pool Cleaner Power Supplies
Choosing the right power supply can feel overwhelming with so many model numbers and compatibility lists. Focus on these key factors to make an informed decision.
Compatibility with Your Cleaner Model
The most critical step is verifying compatibility with your specific pool cleaner. Most replacements, like the 99956034 unit, work with multiple Dolphin models, including Active 10, E10, Echo, and S50. However, some cleaners use a 4-pin connector (for units with timers or Bluetooth) while others use a 2-pin plug. Always check your existing power supply’s model number and connector type before ordering. A mismatch means the unit simply won’t work, and you will waste time with returns. If you are unsure about connector types, read our robotic pool cleaner power adapter for clarity.
Power Output: 120W vs 180W
Power supplies generally come in two wattage classes: 120W and 180W. Most standard Dolphin and Maytronics cleaners require a 120W unit (29V DC output). However, some models, especially those with stronger pumps or additional features, need 180W (around 28V DC at higher amps). Using a 180W supply on a cleaner designed for 120W is usually safe because the cleaner only draws the power it needs. But a 120W supply may overheat or fail if used on a 180W cleaner. Match the wattage to your original part for reliability.
Smart Features: Timers and Bluetooth
Basic replacement units offer simple on/off operation. More advanced models include a built-in weekly timer that lets you schedule cleaning cycles daily, every other day, or every third day. The premium choice is a Bluetooth smart power supply that connects to your smartphone, enabling scheduling, cycle selection, and even delay start. If you want to automate your pool cleaning without touching the unit, a timer or Bluetooth model is worth the extra cost. For basic use, the standard on/off supply works fine.
Durability also matters: look for IP54 waterproof rating and aluminum heat sinks for better heat dissipation, which prolongs the unit’s life. Most replacements include a new power cord, saving you from reusing old, frayed cables. For more tips on maintaining your cleaner, visit our Replacement Parts category page.
Final Thoughts
For most users, the For Dolphin Pool Cleaner Power Supply 180W by E-cowlboy is an excellent all-around choice with its 180W output, weekly timer, and compatibility with many 4-pin Dolphin models. If you need a simple, reliable replacement for standard 2-pin cleaners, the 99956034 Power Supply Parts for Dolphin Active 10 by Hihitomorrow offers solid performance at a great value. Both options restore your cleaner to full power and come ready to install right out of the box, so you can get back to enjoying a clean pool.

Frequently Asked Questions
How do I know if my robotic pool cleaner power supply is failing?
Common signs include the cleaner not starting, stopping mid-cycle, or showing intermittent power. You may also notice a burning smell, overheating, or visible damage to the unit. If the power supply feels unusually hot or makes buzzing noises, it is likely failing and should be replaced.
Can I use a 180W power supply on a cleaner that originally used 120W?
In many cases, yes, as long as the voltage matches (both are typically 28-29V DC). The cleaner will draw only the power it needs. However, always check the manufacturer’s specifications. Using a higher wattage supply than recommended is generally safe but verify connector compatibility first.
What is the difference between a 2-pin and 4-pin power supply connector?
The 2-pin connector is used on basic on/off models, while the 4-pin connector supports smart features like timers and Bluetooth. They are not interchangeable. If you have a 4-pin power supply, you need a 4-pin replacement. Always check the connector on your current unit before buying.
Will a replacement power supply work with my Dolphin Nautilus CC Plus?
It depends on the model year. Older Nautilus CC Plus units use a 4-pin connector and are compatible with the 180W 9995672-US-ASSY power supply. Newer Bluetooth models require the 99956035 unit. Check your existing power supply’s part number to ensure a perfect fit.
