Built to clean like nothing before
Waterline Cleaning
From the floors to the waterline, every ProLine™ model cleans the entire pool with increased performance at this problematic area.
Commercial-Grade Motors
ProLine™ models use professional-grade motors and suction to filter more water, vacuum more debris, and scrub like no other Dolphin before.
NanoFiltration™
Every ProLine™ includes NanoFilters™ in the box. They clean deeper than standard Dolphin robots, capturing microscopic debris.
2–3 Year Warranty
Backed by a 2–3 year manufacturer warranty — the longest coverage Dolphin offers — plus free shipping and support from our pool cleaning specialists.
ProLine™ models
With commercial-grade motors, NanoFilters™, weekly timers, and more, the Dolphin ProLine™ is everything a robotic pool cleaner should be.
Dolphin Quantum
Equipped with the largest top-loading NanoFilter MaxBin™ and programmable timer, the Quantum is the entry-level ProLine robot. Powerful DC motors, PowerJet 3D Mobility & SmartNav 2.0™ power it over any obstacle.
Dolphin Premier
The Premier stands out with its exclusive MultiMedia™ technology. Switch between its oversized leaf bag and NanoFilters™ in seconds for an extraordinary clean.
Dolphin Sigma
The most advanced Maytronics robot ever. The Sigma's revolutionary gyroscope, myDolphin™ Plus app, and NanoFilters™ combine for an automated, more powerful clean.
Automate your pool cleaning
Unleash full automation with the Dolphin ProLine™. Each robot includes a Weekly Timer, letting you schedule daily cleanings effortlessly — your pool is taken care of, every single day.
A 60ft cord and anti-tangle swivel let ProLine™ robots navigate your entire pool. Simply remove the robot to clean its filter, and let ProLine™ handle the rest.
Any pool. Any time.
With a 60ft cable and Anti-Tangle Swivel, every Dolphin ProLine™ model is engineered to clean any pool surface or shape up to 50ft. Whether you have gunite, fiberglass, or vinyl, there isn't a pool a ProLine™ robot can't clean.
NanoFiltration™
Only Dolphin ProLine™ robots include NanoFilters™ in the box. These Gen-2 filters capture microscopic debris that standard Dolphin filters miss — for a crystal-clear pool right out of the gate.
SmartNav 2.0™ Scanning
SmartNav 2.0™ scans and maps your pool, optimizing the cleaning path for maximum efficiency so every inch gets a precise, thorough clean.
Commercial-grade motors
Taken from the Dolphin Wave commercial lineup, ProLine™ robots use commercial-grade motors for more power and suction — filtering over 75 gallons per minute.
With dual scrubbing brushes on each robot, ProLine™ robots don't just vacuum — they actively scrub and attack debris, keeping your pool crystal clear.
The ultimate robotic pool cleaners
There has never been a pool robot like it. Designed to clean from the ground up with more power and precision, experience the Dolphin ProLine™ in your own pool today — backed by a 2–3 year warranty, it's never been easier.
