Hihitomorrow 99956034 is a direct replacement power supply assembly with a 5898412LF black power cord designed to restore power to compatible Dolphin Active and Premium robotic pool cleaners.

If your Dolphin Active 10, Echo, Encore, Escape, E10, S50, Solo, T15, Premium 10, or Premium 20 cleaner has stopped powering up or you see intermittent operation, replacing the OEM 99956034US-ASSY with this Hihitomorrow assembly brings the unit back to its original on/off functionality. This replacement is a 120W basic power supply intended for models without Wi‑Fi or advanced smart controls. The unit includes an anti‑corrosion PCB, an aluminum heat sink behind the bottom grill, a molded top handle, and the included 5898412LF black power cord for quick swap‑out and dependable electrical connection.

How do I know this power supply fits my Dolphin cleaner?

Check your cleaner model and control box: this assembly is specifically made for Dolphin models that use a simple on/off power supply rather than Wi‑Fi or smart controllers. Confirm the OEM part number on your existing power supply—if it reads 99956034US‑ASSY or a similar 99956034 designation, this unit matches the original specification.

• Compatible models: Active 10, Echo, Encore, Escape, E10, S50, Solo, T15, Premium 10, Premium 20.
• Designed for basic on/off models only, not for Wi‑Fi-enabled cleaners.
• OEM replacement reference: 99956034US‑ASSY compatibility.
• Included cord: 5898412LF black power cord for direct replacement.

What performance and build features does this replacement offer?

The Hihitomorrow assembly delivers the same nominal 120W output as the original part and is built to withstand poolside conditions. It uses a quality PCB treated against corrosion and heat, and an aluminum heat sink to manage thermal loads. A molded handle eases transport and installation and the included cord connects securely to the cleaner and mains supply.

• Power rating: 120W suitable for basic Dolphin models.
• Durability: PCB treated for anti‑corrosion and high temperature resistance.
• Cooling: internal aluminum heat sink behind the bottom grill.
• Ergonomics: integrated top handle for carrying and replacement.

How do I replace the old unit and what should I watch for?

Replacement is straightforward: disconnect power, remove the existing assembly, and swap in the Hihitomorrow unit using the same mounting points and cord connections. Inspect plugs, cable grommets and seals for wear and ensure the cleaner is compatible with an on/off style supply. If you observe damaged plugs or exposed wires, replace the cord before powering on.

• Safety first: unplug mains before starting replacement.
• Use existing mounting points and confirm secure connections.
• Check seals and cable condition; replace damaged cables immediately.
• Test the cleaner briefly after installation to confirm steady operation.

Will this restore all features of my Dolphin cleaner?

This replacement restores basic power and on/off functionality for supported Dolphin models. It does not add Wi‑Fi or smart features; if your cleaner originally supported those functions, use the corresponding OEM smart power module. For basic models, the Hihitomorrow assembly returns reliable, consistent power for everyday cleaning cycles.

• Restores standard on/off operation for compatible models.
• Not a retrofit for Wi‑Fi or advanced control modules.
• Supplied cord and assembly mirror the original basic configuration.
• Ideal for repair, maintenance, and refurbishment of basic Dolphin cleaners.

Who is this for: Pool owners, service technicians, and maintenance shops that need an OEM‑compatible replacement for the 99956034 power supply on basic Dolphin robotic cleaners. If your unit is an on/off model and has a failing or damaged power brick or cord, this Hihitomorrow assembly with the included 5898412LF black power cord is a practical, cost‑effective way to restore reliable operation without upgrading to smart modules. For models requiring Wi‑Fi or advanced control features, consult the original manufacturer specifications for the correct replacement part.
