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.

Buying Guide: What to Look for in a Power Supply Replacement Kit
Compatibility with Your Dolphin Model
Not all power supplies fit every Dolphin cleaner. The first step is checking your model’s plug type: 2-pin round plug or 4-pin rectangular plug. Most modern Dolphin units use a 4-pin connector, but older or basic models may differ. Also verify the part number. Many replacements are designed for 99956034 or 9995672-US-ASSY. For example, kits labeled “99956034 power supply” typically work with Active 10, E10, Echo, Escape, and S50. The 180W units with a timer (like the 9995672-US-ASSY) are compatible with Nautilus CC Plus, DX3, and Neptune models. Always cross-check with your cleaner’s manual or our top Dolphin Nautilus power supply options guide.
Power Output and Features: 120W vs. 180W
The two main power ratings are 120W and 180W. Basic models (99956034) provide 120W and are suitable for cleaners with manual on/off controls. The 180W units often add a weekly timer, letting you schedule cleaning cycles daily or every other day. Some advanced kits even include Bluetooth control for scheduling via a mobile app. If you want hands-free operation, a timer or smart model is worth the extra investment. For a comprehensive overview of timer-equipped options, see our best Dolphin power supply with timer article.
Build Quality and Outdoor Durability
Your power supply lives poolside, exposed to moisture, heat, and dust. Look for an IP54 rating, which guarantees splash resistance and dust protection. Quality units also feature an aluminum heat sink to dissipate heat, double insulation, and a thermal protection switch. These elements prevent overheating and extend the lifespan of the unit. Many aftermarket kits now match or surpass OEM build quality, as seen in the DAIERTEK and LOTMOVE offerings.
Ease of Installation and Included Accessories
Most replacement kits are plug-and-play. They come with a new power cord (often 5898412LF) so you don’t need to reuse the old cable. Simply disconnect the faulty unit, connect the new one, and close the enclosure. No tools or wiring knowledge required. A built-in carrying handle makes transportation easy. For a detailed walkthrough, read our top Maytronics Dolphin power supply replacements guide.
Final Thoughts
Choosing the right robotic pool cleaner power supply replacement kit depends on your specific Dolphin model and desired features. For most standard cleaners without WiFi, the 99956034 Power Supply Replacement for Dolphin from sixcow offers a reliable, easy-to-install 120W solution that includes the necessary 5898412LF power cord. If you need automatic scheduling and a higher power output, the For Dolphin Pool Cleaner Power Supply 180W from E-cowlboy is a superb upgrade, restoring peak performance with a built-in weekly timer and convenient on/off switch. Whichever you pick, you’ll extend the life of your cleaner and save money.

Frequently Asked Questions
How do I know which power supply replacement kit is compatible with my Dolphin cleaner?
Check the model number on your current power supply (often 99956034 or 9995672). Then verify your cleaner’s plug type: 4-pin for most modern Dolphin models, 2-pin for some older units. Our product listings specify compatible models. For a complete list, refer to our dolphin WiFi power supply replacement.
Can I replace a 99956034 power supply with a 180W model?
Only if your Dolphin cleaner and plug type are compatible. The 180W units fit models with a 4-pin connector that originally used a 9995672-US-ASSY power supply. Check compatibility before purchase. The higher wattage doesn’t damage the cleaner; it merely provides more power headroom.
What is the difference between a basic power supply and one with a weekly timer?
A basic power supply (120W) has a simple on/off switch. A timer model (180W) lets you schedule cleaning cycles daily, every other day, or every third day. Some advanced versions add Bluetooth for smartphone control. The timer eliminates the need to manually start the cleaner each day.
Is it safe to use an aftermarket power supply for my robotic pool cleaner?
Yes, when purchased from a reputable brand. Many aftermarket units meet or exceed OEM specifications, with IP54 waterproofing, thermal protection, and quality PCB boards. They are designed as direct drop-in replacements. Always ensure proper compatibility and install according to instructions.
