Dolphin Proteus DX4 Pool Cleaner Review
The energy-efficient Dolphin Proteus DX4 pool cleaner lets you sit back and relax while it does the cleaning for you, tackling the walls and floor of pools up to 50 feet in just two hours.

Why is Dolphin Proteus DX4 Pool Cleaner worth it?
If you don’t have the time or energy for weekly pool cleaning chores, the Dolphin Proteus DX4 is a worthy investment. Its energy-efficient design allows it to powerfully clean your in-ground pool without needing an existing filtration system, running instead on its own power supply. It uses two active brushes to deeply clean the floor, walls, and waterline with a powerful suction rate of 4000gph. The easy-access top-load basket effectively traps even the finest particles. Set this robotic cleaner on a weekly schedule to clean every day, every other day, or every third day and never worry about manually cleaning your pool again.
What is the difference between the Dolphin Proteus DX4 Pool Cleaner and competitors?
The robotic Dolphin Proteus is eight times more efficient than pressure- and suction-type cleaners. It doesn’t rely on your pool’s pump and filtration system and doesn’t require extra pumps or hoses. Instead, it uses its own power supply with a 60’ tangle-free cable, expending only five cents per hour. The Dolphin uses an intelligent scanning system to clean the entire pool, allowing it to scrub places that others may miss.
What design features of the Dolphin Proteus DX4 Pool Cleaner will enhance the user's experience?
The Dolphin Proteus weighs only 16.5 pounds and has a quick water release feature that makes it easy to remove from the pool between cleaning sessions. A 60’ tangle-free swivel cable allows it to move freely, while powerful suction enables superior wall climbing and water line cleaning. Scheduling weekly cleaning is easy- simply turn it on and drop it in the pool if you prefer to clean only as needed. The top-loading XL basket is easy to clean and has interchangeable filters.
What drawbacks of the Dolphin Proteus DX4 Pool Cleaner should the user consider?
Some reports indicate that the Dolphin Proteus may need to work out kinks in the robotics department. After only a handful of uses, users find that the Dolphin becomes restricted to a limited path or gets stuck in certain places, failing to clean the entire pool. Some users also had trouble with the cleaner unexpectedly turning off or having trouble connecting to the app. While the Dolphin is effective on most pool surfaces- including concrete, vinyl, plaster, and fiberglass- users find it may not be the best for gunite surfaces.

FAQ
We've researched and answered some common questions that arise when consumers are shopping for pool cleaners.
How long can I leave my Dolphin Proteus in the pool?
You should take your Dolphin out of the pool after each use to rinse out the filter and rinse off any excess chemicals. While it is not harmful to swimmers, removing it from the pool between uses will prolong its quality. If your Dolphin is set on a weekly schedule, you should remove it from the pool once a week to clean the filter. The Dolphin should be stored in a dry, sheltered place when not in use.
Will the filter capture fine particles like pollen and sand that have settled on the bottom of the pool?
Users find that the Dolphin’s fine filter is very effective at capturing fine materials like pollen, sand, and dirt that have settled on the bottom of the pool. If your pool has not been cleaned for a long time- such as over the winter- it may take the Dolphin multiple cycles to completely clean up all of the debris. Users also report that the Dolphin’s extreme scrubbing action does a superior job of cleaning the waterline.
What are the handles and floats on the Dolphin for?
The handles on the Dolphin Proteus DX4 are used to determine the speed at which the cleaner moves along the waterline. The Dolphin will travel less distance at a slower speed but scrub longer. It will travel a greater distance at a faster speed but spend less time scrubbing each spot.

Final Thoughts
The lightweight Dolphin Proteus DX4 thoroughly cleans in-ground pools of any shape up to 50 feet long in two hours. It does not rely on your pool’s filtration system, thus reducing water, chemical, and energy usage. The Dolphin can be set on a weekly cleaning schedule and has an easy-access top filter basket.
