Quick Answer: The Dolphin Quantum (about $1,497-$1,649 depending on retailer, list price near $1,799) is Maytronics’ mid-tier corded robot, built around an XXL MaxBin filter (400 sq in capacity) with swappable standard/NanoFilter cartridges and a 4,000 GPH flow rate that clears a 50-ft pool in roughly 2 hours. Robotic Reviews scored it 95/100 and measured it at just 16 lbs — but it has no Wi-Fi or app, running instead on a built-in weekly timer, and it is not the Dolphin that reliably climbs sun shelves and steps. That headline feature belongs to the pricier Dolphin Quantum Pro, a separate model this site’s own comparison content has previously mixed up with the base Quantum reviewed here.
Search interest in “Dolphin Quantum” is unusually high for a mid-tier robot, and a likely reason is exactly this confusion: retailers and even some review sites blur the base Quantum with the newer Quantum Pro, which shares the name but adds an app and a dedicated shallow-water climbing system. Here’s what the base Quantum actually does, verified against Robotic Reviews’ hands-on test and Poolbots’ independent review, plus where it stands next to its Dolphin siblings.

By the numbers
- Independent score: Robotic Reviews scored the Quantum 95/100 in hands-on testing, calling it a solid, well-designed machine focused on core cleaning performance over smart features.
- Filter capacity: The XXL MaxBin holds 400 square inches of filter media, per Robotic Reviews’ measurements — swappable between a standard filter and ultra-fine NanoFilters that capture particles as small as 2 microns.
- Real-world cycle time: Robotic Reviews clocked a full clean at about 2.5 hours in testing, slightly longer than Maytronics’ spec of 2 hours for a 50-ft pool.
- Weight: At about 16 lbs, the Quantum is meaningfully lighter than the 20+ lb Premier and Sigma, making it easier to lift out solo after a cycle.
What it does well
Strong core cleaning at a lower weight. The 4,000 GPH flow rate and 400 sq-in filter give the Quantum real filtration muscle without the 20+ lb bulk of the Premier or Sigma — Robotic Reviews’ 95/100 score reflects consistently thorough floor and wall passes in testing.
NanoFilter option without paying flagship prices. Swapping in the 2-micron NanoFilter cartridge for algae season, then back to the standard filter the rest of the year, is normally a feature reserved for pricier Dolphins — the Quantum offers it at a mid-tier price point.
Simple, reliable timer control. No app to configure or Wi-Fi to troubleshoot — the built-in weekly timer just runs on schedule, which some owners genuinely prefer over app-dependent competitors.
Where it falls short
- No Wi-Fi, despite a wireless-looking icon. Robotic Reviews specifically calls out a Bluetooth/wireless icon printed on the power supply that could mislead buyers into expecting app control — the Quantum has none. If phone scheduling matters to you, look at the Quantum Pro or the Nautilus CC Plus Wi-Fi instead.
- Not a reliable sun-shelf/step climber. This is the single most common point of confusion buyers run into: the Quantum eventually scrubbed steps and a tanning ledge in Robotic Reviews’ test, but slowly, and some owner reviews describe it struggling on sitting ledges. The Quantum Pro — a distinct, pricier model with SmartNav 2.0 and HyperGrip tracks — is the one Maytronics actually engineered and markets for shallow-water climbing.
- Wide price spread. Robotic Reviews cites retailers as low as $1,047-$1,227, other listings closer to $1,649, and list price near $1,799 — a wider spread than most Dolphins, so it pays to shop around before buying.
- Standard scanning, not gyroscope-guided. Like most Dolphins below the Sigma, the Quantum uses a standard scanning pattern rather than mapped navigation, so coverage can occasionally miss a section on irregular pool shapes.
Dolphin Quantum vs the alternatives
| Model | Wi-Fi/app | Sun shelf/steps | Warranty | Price |
|---|---|---|---|---|
| Dolphin Quantum | No — weekly timer only | Not a marketed feature | 2-year | ~$1,497-$1,649 |
| Dolphin Quantum Pro | Yes — myDolphin Plus | Yes — SmartNav 2.0 + HyperGrip, first Dolphin built for it | 2-year | Higher than base Quantum |
| Dolphin Premier | No — weekly timer only | Not rated for this | 3-year | ~$1,999 |
| Dolphin Nautilus CC Plus | Yes — Wi-Fi | Not rated for this | 1-year (US) | ~$749 |
| Dolphin Sigma | Yes — Wi-Fi + Bluetooth | Not rated for this | 3-year | ~$1,499 typical |
If shallow-water climbing is the feature you actually want, the model to buy is the Dolphin Quantum Pro, not this one — confirm the “Pro” name is on the box or listing before purchasing. If you want app control without paying Pro pricing, the far cheaper Nautilus CC Plus has Wi-Fi built in, just without the Quantum’s larger filter capacity. Against the flagship Dolphin Premier, the Quantum is lighter and usually cheaper but gives up a full year of warranty coverage and the Premier’s oversized leaf-bag option.

Who should buy the Dolphin Quantum
Buy it if you want a lighter, high-filtration corded robot for a standard inground pool without paying flagship prices, and you’re fine scheduling cleans on a built-in timer rather than a phone app.
Skip it if a sun shelf, Baja ledge, or steps are the actual feature you’re shopping for — that’s the Quantum Pro, not this model. Also skip it if app control matters more than filtration capacity — the cheaper Nautilus CC Plus has Wi-Fi built in.

The bottom line
The Dolphin Quantum (~$1,497-$1,649) is a genuinely capable mid-tier robot — a 95/100 from Robotic Reviews, a large 400 sq-in filter, and a lighter 16 lb body than its Dolphin siblings. But it’s not the shelf-climbing, app-connected robot some retailer listings and comparison pages imply; that’s the separate Quantum Pro. Buy the base Quantum for straightforward floor/wall/waterline cleaning at a fair mid-tier price, and only step up to the Pro if sun-shelf climbing and app control are must-haves.
