Quick Answer: The Dolphin Quantum Pro ($1,999 MSRP, per The Pool Nerd’s 2026 Dolphin roundup) is Maytronics’ Wi-Fi-connected redesign of the Quantum platform — the first Dolphin engineered with SmartNav 2.0 navigation and HyperGrip tracks to reliably climb onto and scrub sun shelves, Baja ledges, and steps in water as shallow as about 12 inches. It pairs that with the myDolphin Plus app, dual HyperBrush scrubbing, and the same large-capacity XXL MaxBin filtration as the base Quantum. This is the model buyers actually want when they search “Dolphin Quantum” looking for shelf-climbing or app control — features this site’s own base-Quantum coverage has previously had to correct after mixing them up with this pricier Pro model.
Confusion between the base Dolphin Quantum and this Quantum Pro is common across retailer listings and even some review sites, since both share the “Quantum” name and core XXL MaxBin filtration. Here’s what actually sets the Pro apart, verified against The Pool Nerd’s hands-on 2026 test and Poolbots’ independent coverage.

By the numbers
- Shallow-water reach: SmartNav 2.0 and HyperGrip tracks let the Quantum Pro climb and clean in water as shallow as about 12 inches, per The Pool Nerd’s hands-on test — deep enough into sun-shelf and step territory that most corded robots can’t reach.
- Price premium: At $1,999 MSRP, the Quantum Pro runs several hundred dollars above the base Quantum’s $1,497-$1,649 typical street price — the gap buys Wi-Fi, the app, and the shelf-climbing system.
- Roundup ranking: The Pool Nerd’s 2026 Dolphin lineup test ranks the Quantum Pro #2 Best Inground, calling it “one of the most well-rounded robotic pool cleaners” tested that year.
- Shared filtration: Both the Pro and base Quantum use the same XXL MaxBin filter housing with interchangeable standard and NanoFilter panels — the filtration upgrade over cheaper Dolphins isn’t Pro-exclusive.
What it does well
Actually engineered for shelf and step cleaning. Where the base Quantum only stumbles onto steps and ledges eventually, the Pro’s SmartNav 2.0 + HyperGrip combination is purpose-built for it — The Pool Nerd confirms reliable coverage down to roughly 12 inches of water, a genuine differentiator most competitors, corded or robotic, don’t match.
App control without stepping up to the flagship Sigma. The myDolphin Plus app brings scheduling, spot-cleaning, and manual steering to a ProLine-tier robot at a lower price than Maytronics’ triple-motor Dolphin Sigma.
Commercial-grade build in a residential package. The Pool Nerd’s roundup notes the Quantum Pro carries ProLine classification with commercial-grade motors, dual HyperBrush rollers, and the PowerJet 3D mobility system — more scrubbing hardware than the base Quantum’s single-brush setup.
Where it falls short
- A real price jump over the base Quantum. At $1,999 MSRP, you’re paying several hundred dollars more than the base Quantum’s typical street price for the app and shelf-climbing — skip it if your pool has no shallow shelf or steps to clean.
- Still a 2-year warranty. Despite the premium price, the Quantum Pro doesn’t match the 3-year non-prorated coverage on Dolphin’s Premier — a shorter warranty term for a higher purchase price than some other Dolphins.
- Name confusion with the base Quantum. Because both share the “Quantum” name and the same XXL MaxBin filter branding, retailer listings and even review sites frequently blur the two — confirm “Pro” is explicitly on the box or listing before buying if shelf-climbing or the app is the reason you’re shopping.
- No gyroscope-mapped navigation. Unlike the flagship Dolphin Sigma, the Quantum Pro’s SmartNav 2.0 is purpose-built for shallow-water climbing rather than full gyroscopic pool mapping.
Dolphin Quantum Pro vs the alternatives
| Model | Wi-Fi/app | Sun shelf/steps | Warranty | Price |
|---|---|---|---|---|
| Dolphin Quantum Pro | Yes — myDolphin Plus | Yes — SmartNav 2.0 + HyperGrip, ~12 in water | 2-year | $1,999 MSRP |
| Dolphin Quantum (base) | No — weekly timer only | Not a marketed feature | 2-year | ~$1,497-$1,649 |
| Dolphin Premier | No — weekly timer only | Not rated for this | 3-year | ~$1,999 |
| Dolphin Sigma | Yes — Wi-Fi + Bluetooth | Not rated for this | 3-year | ~$1,499 typical |
| Dolphin Nautilus CC Plus | Yes — Wi-Fi | Not rated for this | 1-year (US) | ~$749 |
If shelf/step cleaning isn’t a priority, the base Dolphin Quantum shares the same filtration and scrubbing hardware for several hundred dollars less. Against the Dolphin Premier, which sits at a similar $1,999 price point, the Pro trades the Premier’s oversized leaf-bag option and extra warranty year for app control and shelf-climbing — pick based on whether your pool has heavy leaf debris or a shallow shelf. We compare the Premier against the base Quantum in detail in our Dolphin Premier vs Dolphin Quantum guide, and rank the full lineup in our best Dolphin pool cleaner roundup.
Who should buy the Dolphin Quantum Pro
Buy it if your pool has a sun shelf, Baja ledge, or steps you actually want cleaned, and you want app-based scheduling without paying flagship Sigma pricing.
Skip it if your pool is a standard floor/wall/waterline shape with no shallow shelf — the base Dolphin Quantum delivers the same core filtration and scrubbing for several hundred dollars less. Also skip it if warranty length matters most: the Dolphin Premier offers a full extra year at a similar price.

The bottom line
The Dolphin Quantum Pro ($1,999 MSRP) is the Dolphin to buy when a sun shelf, Baja ledge, or steps are actually part of your cleaning routine — SmartNav 2.0 and HyperGrip tracks make shallow-water climbing a genuinely engineered feature here, not an accidental side effect like on the base Quantum. Add Wi-Fi app control and commercial-grade ProLine hardware, and it earns The Pool Nerd’s #2 Best Inground ranking. But the premium over the base Quantum is real, and buyers without shallow-water features to clean should save the several hundred dollars and buy the base Quantum instead.
