Quick verdict
The filtration-focused Dolphin for owners who'd rather spend on ultra-fine media than on an app. If dust and silt are your problem more than convenience, this is the smart-money pick.
Ideal for
- Dusty or silty pools (ultra-fine filter included)
- In-ground pools up to 50 ft
- Owners who don't want or need an app
Not ideal for
- App-driven owners
- Cordless seekers
- Surface-debris problems
The full picture
The Quantum's pitch is filtration flexibility without the app tax. Maytronics lists floor, wall, and waterline coverage for in-ground pools up to 50 feet, a 2-hour cycle, a weekly timer, an anti-tangle swivel, and both fine and ultra-fine filter kits — the second of which catches the dust and algae haze that standard baskets pass. There's no mobile app, which is exactly why it can undercut the app-connected Sigma while delivering similar underwater cleaning.

The in-depth review
The Quantum is the Dolphin for owners who'd rather spend their money on filtration than on an app. It's a corded cleaner built around fine and ultra-fine media — the smart-money pick when dust and silt bother you more than convenience features do.
Built around the filter
The reason to choose the Quantum is what it catches. The included fine and ultra-fine filter kits pull pollen, silt, and dead-algae dust out of the water instead of recirculating it — the fine particles cheaper baskets let slip through. It also cleans the floor, walls, and waterline of pools up to 50 feet, and a weekly timer runs it on schedule with no phone involved.
What it skips
There's no app and no cordless option — this is a deliberately un-flashy machine. At premium pricing for a no-app robot, you're paying for cleaning and filtration rather than tech, and that trade only makes sense if fine debris is genuinely your problem.

Frequently asked questions
Is the Dolphin Quantum cordless or corded?
The Dolphin Quantum is corded — it runs on continuous mains power through a floating cable, so there is no battery to recharge between cycles.
What does the Dolphin Quantum clean?
The Dolphin Quantum is rated to clean the floor, walls and waterline. That includes the waterline, where sunscreen and body oils build into a greasy ring. It is an underwater cleaner, so it does not skim floating debris off the surface.
What size pool is the Dolphin Quantum designed for?
It is rated for pools up to 50 feet. On a longer pool it covers less ground per cycle and can miss spots, so size up if your pool runs past that.
Does the Dolphin Quantum have app control?
No — the Dolphin Quantum runs from on-unit controls rather than a mobile app, though it does include a weekly timer.
What filtration does the Dolphin Quantum use?
It filters debris through a fine and ultra-fine filter kits. Rinse it after each cycle so suction and pickup stay strong.
What warranty does the Dolphin Quantum come with?
It comes with a 3-year limited manufacturer warranty (confirm current terms at purchase).
