THE ALL-NEW 2026
Max-Series™ with XXL MaxBin™
The new 2026 Dolphin Quantum Pro leads the pack. With a larger XXL MaxBin™, HyperBrush™ Technology, and NanoFiltration™, the Quantum combines cutting-edge waterline cleaning with powerful dual motors. Powered by SmartNav 2.0™ scanning software, the Quantum Pro navigates and vacuums your pool with power and precision.
ANY POOL TYPE, SHAPE, OR SURFACE
Built for All Swimming Pools
The Dolphin Quantum Pro works on all swimming pools. Whether you have a gunite, fiberglass, or vinyl pool, the Quantum is the perfect cleaner. With a 55ft cable and anti-tangle swivel, the Quantum Pro is rated for pools up to 50ft in length.
CLEANING HAS NEVER BEEN EASIER
Automate Your Pool Cleaning
An all-in-one automatic robotic pool vacuum cleaner, the Dolphin Quantum Pro does it all. With powerful motors and HyperBrush™ technology, the Quantum attacks leaves, dirt, and debris. The Quantum Pro's Weekly Timer allows you to automate pool cleanings so it runs daily — that way you can sit back and relax while the Quantum cleans for you.
THE LARGEST DOLPHIN FILTER EVER.
XXL MaxBin™
The new XXL MaxBin™ is our largest filter yet. At over 400in2, it is 225% larger than Gen-1 Dolphin filters. With the ability to capture and trap more debris, the MaxBin simplifies pool cleaning.
With one click, you can clean your MaxBin™ as it opens to remove any captured debris. No more messing with complicated filter cartridges or messy debris bags. But rather the cleaning process has been simplified to just one click.
INCLUDES GEN-2 FILTERS
NanoFiltration™
Snap in and go. The Dolphin Quantum Pro is the only Dolphin to include both standard filters and a full set of XXL NanoFilter™ panels. NanoFilters trap contaminants that pass right through standard cartridges — pollen, algae, bacteria, and even oils — for a polished, crystal-clear pool the Quantum's competition can't match.
A DOLPHIN FIRST
Cleans Sun Shelves, Baja Ledges & Stairs
The Dolphin Quantum Pro goes where no Dolphin has gone before. Powered by SmartNav 2.0™ mapping and the grip of continuous HyperGrip™ tracks, the Quantum is the first Dolphin engineered to climb onto and clean the shallow features other robots leave behind.
Sun shelves & tanning ledges — the Quantum slides up and scrubs the surface clean
Baja ledges — full coverage across the entire ledge, not just the floor below it
Stairs & steps — methodically navigates each step instead of skipping over them
No more brushing the shallow end by hand. The Quantum Pro handles every inch of your pool — floor, walls, waterline, ledges, and steps — automatically.
CLEAN WHAT OTHER ROBOTS CAN'T
Advanced Filtration
Snap in and go. The 2026 Dolphin Quantum Pro's included XXL NanoFilter panels drop right into the MaxBin and unlock a deeper clean than any robot before it.
SMART, EFFICIENT NAVIGATION
SmartNav 2.0™
Gone are the days of watching your robot aimlessly wander around your pool, wondering if it will ever pick up the leaves it has skipped day after day. The new Dolphin Quantum Pro is equipped with SmartNav 2.0™ Robotic Scanning to ensure that every inch of your pool surface is reached. SmartNav software delivers highly optimized scanning and coverage for a new level of clean. The Quantum calculates the optimal pattern for faster cleaning and improved efficiency.
With its remarkable pool mapping system, the Quantum Pro knows where it has and hasn't been to avoid overlapping cleaning paths and minimize cleaning time. With the ability to sense ladders and drains, the Quantum won't get hung up like ordinary cleaners. Microprocessor-controlled pool scanning ensures complete, efficient pool surface coverage.
LIGHTWEIGHT ERGONOMIC DESIGN
Leaner and Lighter
As a leader in efficiency, the new Dolphin Quantum Pro redefines what it means to look and feel like a robotic cleaner. Its newly designed frame is sleek and low to the ground for minimal water resistance as it moves along your pool's slopes and walls. The new Exoskel is a minimalist architecture that keeps only essential structural parts.
It reduces the weight while creating a strong, modern and cutting-edge design that defines the Quantum's unique abilities. The Quantum was given a convenient carry handle located near the front for easy handling. A new fast water release system quickly removes excess weight and ensures the Quantum Pro remains lightweight and easy to carry, even after a full two hours in your pool.
ATTACK TOUGH CONTAMINANTS
HyperBrush Dual Scrubbing
Virtually any pool cleaner can vacuum loose debris, but it takes a special type of robot to remove contaminants that adhere to the pool surface. Traditional cleaners merely pass over difficult-to-remove pathogens, leaving them fully intact. The Dolphin Quantum Pro was engineered from the ground up to deep clean. Engineers gave the Quantum dual scrubbing brushes that attack the bacteria, algae, and biofilm firmly attached to the pool wall.
The HyperBrush™ spins two times the speed of ordinary brushes to dislodge even the most difficult, stuck-to-the-wall contaminants. HyperBrush is especially effective against biofilm, a structured community of microorganisms that increases chlorine demand, destroys water quality, and frustrates pool owners. Guided by SmartNav 2.0™, the Quantum Pro's dual high-RPM brush power scrubs every square inch of any pool with remarkable efficiency.
LEAVE WHEELED CLEANERS IN ITS WAKE
HyperGrip™ Continuous Tracks
Water in between the wheels and pool surface makes it difficult for ordinary robots to maintain traction. Continual slippage results in lost energy efficiency and reduced performance. The Dolphin Quantum Pro takes a radical departure from the conventional wheel with continuous rubber tracks. The Quantum maintains constant contact even when climbing slippery surfaces. No more slipping.
No more wasted energy. The rubber track also improves directional control and provides greater force than wheels. Tracked robots glide smoothly over obstacles like drains and are capable of climbing straight up vertical walls. The Quantum Pro's traction is further improved with a high-grip, water-optimized tread and geometric shape, minimizing rolling resistance for superior weight distribution, traction, and wall climbing.
AUTOMATE YOUR CLEANINGS
Just Say When
The Dolphin Quantum Pro is equipped with programmable run frequency and cleaning duration so you're always in full control. With programmable modes, you can set the Quantum to automatically run when you need it — daily, 2x per week, or 3x per week. The Quantum comes with a built-in, programmable weekly timer to ensure that even if you are out of town, your pool stays clean and ready to enjoy.
The Quantum Pro is engineered to clean quickly and thoroughly. This means you can schedule your robot to run less often. The Quantum will complete a cleaning cycle in pools up to 50 feet long in just two hours. The new advanced controls allow you to run the Quantum only as needed instead of every day, saving even more energy.
BEST‑IN‑CLASS WARRANTY
2 Year Warranty & 30 Day Trial
By purchasing from us or one of our Authorized Dolphin Dealers, you'll get a full 2 year manufacturer warranty on your Dolphin Quantum Pro. Not limited to cycles or prorated, this ensures your investment is protected. With hundreds of dealers across the country, servicing your robot is easy.
By shopping direct or from one of our dealers, every Dolphin Quantum includes a 30 Day Trial. Doesn't work for your pool or want to upgrade to a better unit? We've got you covered.
Over 400 square inches, which is 225% larger than Gen-1 Dolphin filters. It opens with one click to empty, and it takes both the standard panels and the XXL NanoFilter™ panels that come in the box.
Does the Quantum clean sun shelves and stairs?
Yes. It is the first Dolphin designed to clean sun shelves, Baja ledges and stairs as well as the floor, walls and waterline. SmartNav 2.0™ senses ladders and drains along the way.
Can I control it from my phone?
Yes. The myDolphin™ Plus app connects over Wi-Fi to start and stop the robot, set the schedule, switch cleaning modes and send alerts. The weekly timer on the power supply works without the app: every day, every 2 days or every 3 days.
How long is a cycle?
About 2 hours for pools up to 50 ft. Because the Quantum is corded it is always cleaning and never charging, so you can run a second cycle straight away after a storm.
Will it work in my pool?
In-ground pools up to 50 ft in any shape, on gunite, plaster, pebble, tile, vinyl liner or fiberglass. Not sure? Ask a Dolphin specialist before you buy.
What does the 2-year warranty cover?
Maytronics warrants the robot against defects in materials and workmanship for 2 years. It is not prorated and not limited by the number of cycles. Service is available through 1,200+ Dolphin dealers. Read the full warranty.
What if it isn't right for my pool?
