Detailed Review

The Dolphin Premium 20 is a robotic pool vacuum cleaner designed for in-ground pools of all shapes and surface types. It targets pool owners who want a reliable, hands-off cleaning solution that delivers spotless results without daily effort. With its powerful wall-climbing capability and active scrubbing brush, this unit cleans both floors and walls thoroughly.

Standout features include a top-load filter basket that makes debris removal quick and easy, plus a plug-and-play system that removes the need for complex setup. Just activate the power supply, drop the robot in, and it runs a full cleaning cycle in two hours. The active scrubbing brush ensures sticky dirt and algae are lifted, leaving surfaces pristine.

Build quality is consistent with Dolphin's reputation for durability. The unit weighs about 23 pounds and has a compact footprint, making it easy to carry and store. The gray color is neutral and fits most pool environments. While it lacks smart connectivity features such as app control or programmable schedules, its straightforward operation is a plus for those who prefer simplicity.

One potential drawback is the absence of Wi-Fi or Bluetooth, which limits automation. Additionally, the price point may be higher than some entry-level cleaners, but the robust construction and performance justify the investment for serious pool owners. The lack of customer reviews at launch means early adopters should rely on Dolphin's established brand history.

Overall, the Dolphin Premium 20 is an excellent choice for homeowners seeking a dependable, easy-to-use robotic pool cleaner. It delivers strong cleaning performance, requires minimal maintenance, and is backed by decades of expertise. If you value a no-fuss, efficient cleaning solution, this model is well worth considering.

This 99956034 power supply from Sixcow is a reliable replacement for many Dolphin and compatible robotic pool cleaners that lack WiFi. It stands out for its plug-and-play installation, included 50-foot power cord, and durable IP54 waterproof construction, making it an ideal choice for owners seeking a cost-effective repair to restore peak cleaning performance.
Pros & Cons

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
Detailed Review

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.

These Henkgo ultra-fine filter panels are a direct replacement for Dolphin robotic pool cleaners, offering excellent filtration of fine debris like sand and leaves. Ideal for pool owners with compatible Dolphin models seeking an affordable, washable, and easy-to-install filter upgrade.
Pros & Cons

Pros

  • Ultra-fine filtration traps even tiny particles for superior water clarity.
  • Easy numbered installation system reduces setup time and guesswork.
  • Washable and reusable design offers long-term value and eco-friendliness.
  • Broad compatibility with many Dolphin and Maytronics robotic pool cleaner models.
  • Sturdy build quality withstands regular use and cleaning without tearing.

Cons

  • May require more frequent cleaning than standard filters due to ultra-fine mesh trapping more debris.
  • Not compatible with all Dolphin models; double-check compatibility before purchase.
  • Some users may find the initial fit slightly tight on certain cleaner baskets.
Detailed Review

The Henkgo ultra-fine filter panels are a direct replacement for the OEM part 9991467-R4, designed specifically for Dolphin robotic pool cleaners. These pleated cartridge filters are ideal for pool owners who want to maintain sparkling water without frequent skimming. They fit a wide range of models including the S200, Active 20, Proteus DX4, M600, and many more, making them a versatile upgrade for most Dolphin owners.

Standout features include the ultra-fine pleated material that captures sand, gravel, leaves, and even microscopic debris. In real-world use, these filters dramatically improve water clarity compared to standard mesh filters. The numbered panels (1-4) simplify installation: remove in order and replace in reverse, so even first-time users can swap them in minutes. The filters are also washable with a garden hose, retaining their shape and effectiveness after repeated cleanings.

Build quality is reassuringly sturdy. The pleated material holds up well under water pressure and regular cleaning. Each panel measures 9 x 8 x 2.1 inches and weighs just over a pound, making them lightweight yet durable. The white color blends inconspicuously into most pool cleaner baskets. Compatibility is extensive, covering over 25 Dolphin and Maytronics models, which adds significant value for households with multiple cleaners or future upgrades.

One potential drawback is that the ultra-fine mesh may clog faster than coarser filters, especially in heavily debris-laden pools. This means more frequent cleaning sessions, but the ease of rinsing offsets this inconvenience. Additionally, while compatibility is broad, it is not universal, so buyers should verify their specific model before ordering. The initial fit on some cleaner baskets might feel snug, but this ensures a secure seal.

Overall, the Henkgo ultra-fine filter panels offer an excellent balance of performance, durability, and affordability. They deliver professional-grade filtration at a fraction of the OEM cost. For Dolphin pool cleaner owners seeking clearer water and less maintenance, these filters are a smart investment. The simple installation and reusable design make them a practical choice for any pool season.

AI Score
AI score rating is a scoring system developed by our experts. The score is from 0 to 10 based on the data collected by the AI tool. This score doesn't impact from any manufacturer or sales agent websites. Learn more ›
This E-cowlboy replacement power supply restores reliable operation for select Maytronics Dolphin robotic pool cleaners, featuring a reinforced body, built-in cooling, and a matching 5898412LF power cord. Ideal for owners of basic single-cycle models like the Dolphin Active 10, S50, or Prowler 910.
Pros & Cons

Pros

  • Wide compatibility with popular Maytronics Dolphin basic models like Active 10, S50, and Prowler 910.
  • Includes a matching 5898412LF power cord for a complete replacement kit.
  • Premium thermal management with aluminum heat sink and double insulation.
  • Sturdy IP54-rated shell built for outdoor pool environments.
  • Generous 12-month warranty adds peace of mind.

Cons

  • Only works with basic single-cycle Dolphin cleaners that have a simple on/off control, not smart or programmed models.
  • Input power is limited to 100-130VAC, so it won't work directly on 220-240V outlets without a voltage converter.
  • Third-party part, not an original Maytronics unit, which some users may consider less trustworthy.
Detailed Review

The E-cowlboy 99956034 power supply is a direct replacement for the OEM Maytronics 99956034US-ASSY unit used with several Dolphin robotic pool cleaners that operate on a basic single cleaning cycle. It pairs with a new 5898412LF power cord, making it a complete drop-in solution for owners of models like the Dolphin Active 10, Solo, S50, S100, and Prowler 910.

This basic power supply packs a microprocessor-based PCB and an aluminum heat sink to maintain steady DC 29V 120W output during cleaning. The IP54-rated housing resists splashes and dust, while the double insulation and thermal protection switch guard against overheating. In practice, users get consistent, worry-free power delivery that keeps the cleaner moving through a single automated cycle.

The injection molded body is reinforced for impact, deformation, and corrosion resistance, so it can handle harsh poolside environments. A quick start ON/OFF button and a comfortable carrying handle make daily operation and transport easy. The included 5898412LF cord is designed to match the supply, eliminating guesswork about cable compatibility.

Note that this power supply only supports the input range of 100-130VAC, so it is not suitable for international outlets that use 220-240V without a transformer. It also works only with Dolphin models that use the simple on/off single-cycle control, not with advanced cleaners that have timers, LCD displays, or app connectivity.

For owners of compatible Maytronics Dolphin single-cycle pool cleaners, the E-cowlboy 99956034 replacement power supply offers an affordable, well-built alternative to OEM parts. With the included power cord, solid cooling design, and a 12-month warranty, it delivers reliable performance at a lower cost than many branded repairs.

  • Top-load filter access simplifies maintenance and reduces mess.
  • Smart navigation ensures efficient coverage of various pool shapes.
  • Plug-and-play operation makes it extremely user-friendly.
  • Trusted brand with decades of experience in pool cleaning technology.

Cons

  • Only suitable for above-ground pools up to 30 feet, not for larger or in-ground pools.
  • No reviews available yet, so long-term reliability is unproven.
  • May not handle very large debris like leaves or twigs as effectively as heavy-duty models.
Detailed Review

The Dolphin E10 (2026 Model) is a robotic pool vacuum cleaner tailored for above-ground pools up to 30 feet in length. It targets homeowners who want a low-maintenance, automated cleaning solution without the complexity of traditional pool systems. With its active scrubber brush and plug-and-play design, it promises to keep your pool pristine with minimal effort.

Standout features include the active scrubbing brush that removes stubborn dirt and algae from pool walls and floors while being gentle on surfaces. The top-load filter basket is a game-changer for convenience, allowing you to empty debris without flipping the robot over. Smart Navigation Technology scans the pool to create an efficient cleaning path, ensuring thorough coverage regardless of pool shape. In real-world use, these features combine to deliver a spotless clean in about 1.5 hours per cycle.

Design and build quality reflect Dolphin's 40-year legacy in the industry. The unit is compact at 17.19 x 15.78 x 10.39 inches and lightweight at 14.6 pounds, making it easy to deploy and store. The gray finish is practical and blends well with pool surroundings. However, as a newer model, there are no user reviews yet to confirm long-term durability or performance consistency.

Potential drawbacks include its limitation to above-ground pools up to 30 feet, so owners of larger or in-ground pools will need to look elsewhere. Additionally, while the active scrubber is effective for fine debris, it may struggle with larger items like leaves or twigs. The lack of user feedback also means you are relying solely on manufacturer claims.

Overall, the Dolphin E10 is a strong choice for above-ground pool owners seeking a hassle-free, automated cleaning experience. Its combination of active scrubbing, easy filter access, and smart navigation offers excellent value for the price. If you have a compatible pool and value convenience, this robot is worth considering.
