The new Dolphin Quantum Pro takes its place at the top of the Dolphin Max-Series™ line-up and the top echelon of robotic pool cleaners. As part of the Dolphin ProLine™, the new Quantum delivers PowerJet 3D™ Mobility, a massive XXL MaxBin™ with NanoFilters™, smartphone control through the myDolphin™ Plus app, and an efficiency level unmatched by any cleaner in its class.
It's about a new benchmark. We started from scratch and gave everything to make the next Dolphin even better. Highly efficient state-of-the-art DC motors and an ingenious PowerJet 3D™ Mobility platform deliver an exceptional pool-cleaning experience while reducing energy use up to 87%. In a class by itself, the new Dolphin Quantum was designed from the ground up to be easier to own and easier to operate.
The Dolphin Quantum includes the largest MaxBin™ ever offered on a Dolphin. In addition to the standard fine filter, Quantum introduces the next-generation NanoFilter™ in a massive 400 sq. ft. easy-to-clean basket configuration. This micro-pore spun-bonded polyester creates a tight structure that traps even the smallest micron particles.
Most filters capture leaves and large debris, but Quantum stops pollen, algae, bacteria, pet dander, and other microscopic debris in their tracks. The increased pleated surface area keeps cleaning for up to a week, handling a higher volume of contaminants.
The NanoFilter high-efficiency particulate filter prevents contaminants from recirculating in the water you swim in. NanoFilters are the only filter capable of removing oil — it forms a transparent sheath over trapped debris and is removed at cleaning, dramatically improving turbidity and water transparency.
Pleated NanoFilters deliver a higher level of filtration for crystal-clear, polished water. The cloudy appearance caused by small suspended particles is no match for Nanofiltration. Try the Quantum for 30 days and see the difference.
Jet nozzles. Vectored thrust. A range of motion no wheeled or tracked cleaner can touch — including the ability to slide laterally along the wall and hold a fixed position against gravity. The Quantum is propelled by jet drives with thrust-vector control for ultimate maneuverability.
With a powerful HyperBrush™ leading the way along its cleaning path and an additional brush bringing up the rear, the Quantum leaves nothing in its wake. The HyperBrush™ scrubs 2× faster than traditional brushes to dislodge even the most difficult contaminants — algae, biofilm, and stuck-on dirt — before sweeping it all into the XXL MaxBin™.
While the Quantum's PowerJet drive provides vectored thrust, its HyperGrip™ rubber tracks deliver the traction needed to stay locked to any pool surface. Whether your pool is plaster, pebble, tile, fiberglass, or vinyl, the soft, high-grip tracks bite in to eliminate the slipping you'll see from wheeled cleaners.
Gone are the days of watching your robot aimlessly wander around the pool. The Dolphin Quantum is equipped with SmartNav 2.0™ Robotic Scanning to ensure every inch of your pool surface is reached. The revolutionary pool-mapping system knows where the Quantum has been — and hasn't — avoiding overlapping paths and wasted cleaning time.
Onboard sensors continuously measure pool size, shape, obstacles, and water conditions, then feed that data to an advanced navigation algorithm that plans the most efficient path in real time. A full clean of a 60-foot pool, in as little as 2 hours.
Stop wasting valuable time cleaning your robot. Cartridge filters have been around for years, but early adopters found it difficult to scrape out dirt and debris. Consider this problem solved. All four sides of the Quantum's filter are removable for quick and easy cleaning, and the bottom panel is hinged so released debris simply falls out.
The Quantum moves quick, completing a cleaning cycle in pools up to 60 feet long in 2 hours. Its advanced mapping system ensures cleaning paths don't overlap and every inch is touched by its scrubbing brushes. With a built-in programmable weekly timer, your pool stays clean and ready to enjoy — even when you're not there.
Choose to run the Quantum every day, every other day, or every third day — the onboard weekly timer handles the rest. The Quantum will activate, complete its cleaning cycle, and power down on its own, delivering consistent results without daily interaction. All you need to do is empty the bin at the end of the week.
Take full control of your pool from anywhere with the myDolphin™ Plus app. Pair the Quantum Pro to your Wi-Fi to start, stop, and schedule cleanings, switch between cleaning modes, target specific areas of the pool, monitor cycle status, and receive smart alerts straight to your phone.
Every detail of the Quantum was engineered to think for itself. An intelligent power supply coordinates onboard sensors, schedules cleaning cycles, and quietly manages performance in the background — adapting to your pool and your routine so the work is already done by the time you walk outside.
The Quantum's newly designed frame is sleek and low to the ground for minimal water resistance as it moves along your pool's slopes and walls. A convenient carry handle is positioned for easy access, and a fast water-release system sheds excess weight so the Quantum stays light and easy to lift — even after a full two hours in the pool.
The Dolphin Quantum will forever change the way you view a clean pool. Rated as one of the best Dolphin pool robots for 2026, the Quantum picks up where other robots fall short. Try the Quantum in your pool for 30 days, and if you're not 100% satisfied, just return it. Let the Quantum challenge everything you thought you knew about robotic pool cleaners.
Try any robot in your pool for 30 days. We believe a pool robot is an investment, and we know you'll love it. Which is why we have a 30 Day Trial. If you don't love it, simply return the robot. Unlike the other guys, we never charge a restocking fee or any other fees - meaning no restocking fee ever.
Here at Poolbots, we carry only the top models for the top brands. All of our pool robots are backed by a full manufacturer's warranty - not prorated or limited to cycles like other pool robots.

John Rodriguez of "Poolbots" recommended the Dolphin Sigma for my 20x40 Saltwater pool. I have to say, "John was correct...this thing is a beast!" I live in the SoCal desert and the Sigma picks up the fine dirt, sand and phosphate residue. John answered all of my questions. Shipping was quick! Semper Fi — USMC 1984-1992
"Patient, knowledgeable, and took the time to answer all of my questions thoroughly."
Jose provided clear and detailed information about the pool cleaners. His professionalism made the whole process stress-free.

I wish I would have converted my pressure side vac to an electric pool robot a long time ago. It cleans 10x better and completes my pool in 90 minutes.
"Without her multiple emails to the company, this would never have happened."
Shannon assisted me with an ongoing issue since May 2025 with a manufacturer. She went the extra mile and followed up!

Excellent customer service and super fast shipping. I highly recommend Poolbots for all your needs.
"I asked to speak to a human — and was told 'I am a human!'"
I clicked "chat" expecting AI. I was so pleased this company still has human interaction. John was great.

I really appreciate the opportunity to try a robot and be able to swap it. Great return process and customer service.
"A far better and more informed purchase option than Amazon."
John went out of his way to go over all the different units and what might be best for my pool. Absolutely awesome customer service.
"Truly treats you like family."
I had a few issues with my product, but Jose did an amazing job helping me and stayed in constant communication throughout the entire process.
"Jose helped fix my incorrect shipping address... saved me a lot of grief."
His help was excellent. Quick intervention prevented a lost shipment.
"Because of John, I bookmarked Poolbots and will use them for everything."
He was very knowledgeable, professional, and interested in getting you the right product — not just making a sale.
"John was amazing. I had no idea what I needed."
He was very patient. After giving me multiple options and explaining the differences, he offered the perfect unit for my pool.
"Call John, you won't be sorry!"
John guided me through the process of selecting the best pool cleaner robot for my needs. Very highly recommend!
Was the best thing you can buy for your pool. Drop in pool and watch clean. Pool in is brushed and vacuumed to perfection.
The cleanliness of my pool has been greatly improved, and the amount of time that I must expend to maintain a clean pool has been minimized. Yours is an outstanding product: works as is demonstrated. It is in daily use here. Its ONLY detractor is the tendency for its power cord to tangle/kink with repeated use —which requires periodic manual detachment from the control unit, straightening it's cord and reattachment. A retrofit for that would be appreciated!
From the moment I unwrapped it I knew I'd love it. What impressed me the most was the filter baskets, with its removable sides. Compared to my old Dolphin, that used a bag, the I had to empty, wash and scrub, what a laborious pain it was. If I had to mention a deficiency, I'd list the fact that the clean cycle is too short, perhaps there's a longer cycle, that I'm unaware of. I did experience a problem with the filter panels, that started disintegrating about a year after I got, When I contacted Maytronics, they offered to replace them as a one time courtesy Kudos to them!
I've had my Dolphin Quantum for a year now and absolutely love it. I run it year-round since I live in Florida. It performs beautifully and keeps the pool sparking clean. The only problem I have is that the cord attached to the robot doesn't swivel and you get a knotted, tangled mess. Otherwise it is a great investment.
Let leaves pileup for a week, amazing, picked up 95% very satisfied. Dolphin Quantum is a amazing bot.
No, we never charge a restocking fee ever! We know a robotic pool cleaner is a big investment, which is why we offer 30 Day Trials on all robotic pool cleaners!
