Best Dolphin Robotic Pool Cleaners (2026)

The Nautilus CC is the model Dolphin has sold longest in this lineup, rated for pools up to 33 feet with a wall-climbing scrubber brush that actively works algae and grime off the pool walls rather than relying only on suction from the floor. Top-load filter access means lifting the unit out and opening the lid on top, a simpler routine than flipping the whole cleaner over.

It sits in the middle of Dolphin's current price range, above the entry-level AG and E10 models but well below the Wi-Fi-connected Plus, Pro, and Titan versions. That positioning makes it the version most buyers land on when they want proven Dolphin engineering without paying for app connectivity they may not use.

As a tethered design, it needs an outlet within cable reach, and it doesn't include the smartphone app control that the Plus and Pro models add. For a straightforward, well-established Dolphin cleaner without extra features to manage, it's the sensible starting point in this comparison.

The Nautilus AG carries an active scrubber brush and top-load filter access at a price meaningfully below the Nautilus CC, making it Dolphin's clearest value pick in this comparison. It's a 2026 model rather than a carried-over older unit, so the core mechanics are current even without the wall-climbing rating the CC advertises.

Dolphin markets the AG as a more general-purpose cleaner rather than one built specifically around pools up to a stated maximum length, which suits smaller or mid-sized inground pools well. The active scrubber brush still works to loosen debris on contact rather than depending purely on suction.

For a buyer who wants genuine Dolphin build quality without paying for the CC's extended pool-size rating or the app-connected models' Wi-Fi features, the AG is the more budget-conscious way into the brand.

The E10 is positioned as Dolphin's entry point into robotic cleaning, priced alongside the Nautilus AG but built as a simpler model within the current lineup. It keeps the active scrubber brush and top-load filter access that make routine maintenance manageable, without the extended pool-size rating or app features of the pricier Dolphin units.

For a first-time robotic pool cleaner buyer who specifically wants the Dolphin name rather than an unfamiliar newer brand, the E10 offers a lower-risk way in. It suits smaller residential inground pools where basic, reliable floor and wall coverage matters more than premium extras.

Expect a more basic feature set than the Nautilus CC or the Wi-Fi-connected models further up this lineup, since the E10's job is dependable core cleaning at an accessible Dolphin price point rather than comprehensive coverage of every pool surface.

The Nautilus CC Plus builds on the standard CC's wall-climbing scrubber and pool-size rating by adding Wi-Fi app control, so cycles can be started or checked from a phone instead of walking out to the pool deck. A universal caddy is included in the box, useful for storing and transporting the cleaner between uses rather than leaving it poolside.

That added connectivity and the included caddy push the price up over the standard CC, a fair tradeoff for a buyer who specifically values app-based scheduling and status checks over saving the difference. The underlying cleaning mechanics, wall climbing and top-load filter access, carry over unchanged from the base CC model.

For households already used to app-controlled home devices who want that same convenience for pool maintenance, the CC Plus is the clearer choice over the non-connected CC in this lineup.

The Nautilus CC Pro adds dedicated waterline scrubbing to the wall-climbing and Wi-Fi features of the CC Plus, targeting the buildup ring right at the water's surface that floor-and-wall-only cleaning can miss. It's positioned as the more complete Dolphin package below the flagship Titan.

For a pool that regularly develops a visible waterline ring in addition to normal floor and wall debris, the added scrubbing coverage here can be worth the jump over the CC Plus. The Wi-Fi control and top-load filter access from the rest of the lineup carry over unchanged.

At over a thousand dollars, it's a meaningful step up from the entry-level E10, and worth choosing specifically because of the waterline-scrubbing capability rather than for wall climbing or app control alone, both of which the cheaper CC Plus already covers.

The Nautilus Titan is Dolphin's current flagship, combining Wi-Fi app control and waterline scrubbing with what the brand markets as its most powerful motor and largest-capacity filter basket in the lineup. It's built for larger inground pools where a full session needs to cover more surface area without losing suction partway through.

At the top of this comparison on price, it's a purchase that makes the most sense for a genuinely large or heavily used pool rather than an average residential one, where the mid-tier CC Plus or CC Pro already covers the practical needs most owners have.

For a buyer specifically dealing with a large pool, heavy debris load, or wanting the single most capable Dolphin model available rather than the best value, the Titan is the clear pick, with the understanding that it's priced well above every other Dolphin model here.
