Best Pool Robots →The 2026 Dolphin Quantum sits at the top of the ProLine™ line-up — the intersection of power, features, and value. PowerJet 3D™ Mobility, an XXL MaxBin™ with NanoFilters™, SmartNav 2.0™, and smartphone control all come standard.
"For anyone hunting for the ultimate pool-cleaning machine, the Dolphin Quantum is the perfect intersection of power, convenience, and value."
Read the Dolphin Quantum Review →Six breakthroughs — from jet-drive mobility to next-gen filtration and navigation — that redefine what a robotic pool cleaner can do.
Vectored water-jet thrust gives the Quantum a range of motion no wheeled cleaner can match — climbing walls and holding the waterline.
The largest basket Dolphin has ever built — over 225% bigger — loaded with next-generation NanoFilters™.
SmartNav 2.0™ maps your pool in real time, covering every inch of floor, walls, and waterline without wasted passes.
Dual HyperBrushes™ scrub 2× faster to dislodge even stuck-on algae and biofilm before sweeping it into the MaxBin™.
High-traction continuous rubber tracks grip any surface — plaster, pebble, tile, fiberglass, or vinyl — without slipping.
A patented 360° cable swivel lets the cord rotate freely, so it never knots up — cycle after cycle.
The included NanoFilters™ snap into the basket in seconds and pull dirt, algae, and microscopic particles straight out of the water column — keeping contaminants from recirculating back into the water you swim in.
The result is crystal-clear, polished water that standard filters simply can't deliver.
Run the Quantum every day, every other day, or every third day — the built-in weekly timer handles the rest. Or take full control from anywhere with the myDolphin™ Plus app: start, stop, and schedule cleanings, switch modes, steer to a specific spot, and get smart alerts straight to your phone.
The Quantum's newly designed frame is sleek and low to the ground for minimal water resistance as it climbs slopes and walls. A convenient carry handle sits within easy reach, and a fast water-release system sheds excess weight — so it stays light and easy to lift, even after a full two hours in the pool.
Every detail of the Quantum was engineered to think for itself. An intelligent power supply coordinates the 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 Dolphin Quantum will forever change the way you view a clean pool. Rated one of the best Dolphin pool robots for 2026, the Quantum picks up where other robots fall short. Try it 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.
