Pros
- Compatible with two popular Dolphin models (non-WiFi CC Plus and M200)
- Includes floats and swivel to prevent cable tangling
- Cost-effective compared to original manufacturer cables
- 60-foot length suitable for large pools
- Easy to install with 2-prong connector
Cons

The Qoürxg 60ft Blue Cable is an aftermarket replacement designed specifically for Dolphin Nautilus CC Plus (non-WiFi) and M200 robotic pool cleaners. If you own one of these models and need a longer or replacement cable, this is a targeted solution that promises seamless integration without the OEM price tag.
Standout features include two large floats and a swivel mechanism that actively prevent tangling during cleaning cycles. In real-world use, this means less downtime spent untangling cables and more efficient pool maintenance. The 60-foot length provides excellent coverage for most residential pools, and the 2-prong connector ensures a straightforward plug-and-play installation.
Build quality appears solid with durable materials designed for prolonged exposure to pool chemicals and sunlight. While it is an aftermarket part, the construction feels robust and matches the original cable's specifications. The blue color makes it easy to spot in the water.
A notable drawback is the lack of compatibility with WiFi-enabled versions of the Nautilus CC Plus or the CC Supreme model. Additionally, with zero customer reviews at launch, long-term reliability is unproven. Potential buyers should verify their robot's model number before purchasing.
Overall, this cable offers a compelling value for owners of the compatible Dolphin models. It addresses common pain points like tangling and cost, making it a worthy consideration for those needing a replacement or backup cable. Just ensure your robot matches the listed compatibility.
Pros
- Plug-and-play installation with no rewiring needed
- Broad compatibility with many Dolphin and Maytronics models
- Includes a long 50-foot power cord for flexible outlet placement
- Durable build with IP54 waterproof rating and thermal protection
- Restores cleaning performance of existing robotic pool cleaners
Cons
- Only compatible with manual on/off Dolphin models (no WiFi or smart features)
- Aftermarket brand (Sixcow) may not match OEM build quality over time
- No customer reviews yet, so long-term reliability is unverified
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.
Buying Guide for WYBOT Replacement Battery
Compatibility Is Non-Negotiable
The most critical factor is matching your robot model precisely. A battery that fits a WYBOT C1 will not work in an older Ecovacs window cleaner. Always verify the model number and voltage listed in the product description. If unsure, contact the seller with your robot’s part number.
For the WYBOT C1, only the specified replacement battery works perfectly. Mixing up models can ruin the battery and damage your cleaner. Review our AIPER pool cleaner charger for charging compatibility tips.
Battery Type and Capacity
Lithium-ion batteries dominate the market due to their high energy density and low self-discharge. Capacity, measured in mAh, determines run time. A 6.0Ah battery (like the LMYDZER option) can power a full cleaning cycle, while a 700mAh pack suits smaller, low-power devices. Choose capacity based on your cleaning area and cycle length.
Batteries with higher capacity are heavier but offer longer runtime. For a cordless pool cleaner, a 6.0Ah pack is ideal for medium to large pools. Consider accessories that enhance battery life.
Safety Certifications and Build Quality
Look for certifications like FCC, CE, CB, ISO9332, and RoHS. These ensure the battery meets minimum safety standards for overcharge, overdischarge, and short circuit protection. A certified battery reduces fire risk and extends lifespan.
The JIAJIESHI battery carries multiple certifications, while the LMYDZER battery includes built-in protection circuits. Always opt for certified models to protect your investment. For more on robotic vacuum safety, see our Pool Robot Charging Station guide.
Ease of Installation
No one wants a complex installation. The best replacement batteries offer plug-and-play operation with a simple connector. The LMYDZER battery for WYBOT C1 is designed as a perfect 1:1 fit, requiring only a screwdriver. The JIAJIESHI battery requires verifying part numbers and possibly disassembly if used in a window robot.
For pool cleaners, a straightforward swap saves time. If you value zero modification, choose the dedicated model. For older devices, check if additional connectors or adapters are needed.
Final Thoughts
Choosing the right replacement battery boils down to your specific robot model and usage pattern. For owners of the WYBOT C1 cordless pool cleaner, the LMYDZER 6.0Ah Replacement Battery for WYBOT C1 offers the ideal plug-and-play experience with high capacity and safety protections, making it the clear recommendation for restoring full cleaning power. Either choice will breathe new life into your device, letting you get back to spotless surfaces quickly.
