Introduction
The right robot makes pool upkeep so much easier. Today I'm comparing two popular budget picks: the Aiper Seagull 600 and the Dolphin Nautilus CC. Both aim to simplify maintenance, but they perform very differently. Here's how they stack up.
The Aiper Seagull 600 pulls you in with its low price and cordless design. It's budget-friendly, but it falls short in several key areas. In my testing it struggled with basic cleaning, left debris behind, and couldn't navigate the pool well. No active brush and a weak motor made it clear this isn't an all-in-one solution. Want the full story? My detailed review is here.
The Dolphin Nautilus CC brings more power and reliability. Built for smaller in-ground and above-ground pools up to 33 feet, it does well on floor and wall coverage. But dropping the programmable timer and skipping NanoFilters are big drawbacks. My full Nautilus CC review is here.
To sum up, both the Aiper Seagull 600 and the Dolphin Nautilus CC have their features but fall short in key spots. The Seagull 600 lacks the power of a corded robot, and the Nautilus CC has stripped out useful features like the programmable timer. That makes both less ideal if you want an advanced, hands-off clean.
How We Test
When I test robots, I use three categories: pool coverage, filtration, and the feature set and warranty. Together they give a full picture of what a robot does well and where it slips. Each one runs in my pool for three months so I really understand its capabilities and any issues that show up with time.
For the Aiper Seagull 600, coverage was the first thing I tested. It only cleaned the floor, coming up short on inclines and walls. Its fast pace left debris behind, made worse by the lack of a navigation system. It kept getting stuck and cleaning the same spots over and over.
"Over three months, the Seagull 600 just couldn't navigate or clean the way it needs to."
Next was filtration. The Seagull 600's flat filter couldn't handle debris and particles well. That design flaw meant frequent cleaning, since debris collected at the bottom of the unit and made the whole process a chore.
Then features and warranty. The cordless design looked nice at first, but weak motors and long charge times sank it. Users often report battery issues right after the warranty ends, which makes that one-year coverage feel thin.
The Dolphin Nautilus CC performed better. Over three months it covered floors and walls in pools up to 33 feet. The catch was the missing waterline cleaning. It uses a 50ft cord and tracks for solid grip, but it just didn't reach the waterline like I'd want.
Filtration was another focus. The Nautilus CC has a standard fine filter, which struggles with cloudy water or larger debris. Unlike robots with multiple filter options, its capabilities here are limited.
On features and warranty, losing the programmable timer, once a Nautilus CC hallmark, was a letdown. That feature, along with NanoFiltration, has moved to the newer Dolphin Cayman. The Nautilus CC does come with a two-year warranty from Maytronics, which speaks to its reliability.
In the end, despite all the testing, both the Aiper Seagull 600 and the Dolphin Nautilus CC fell short in key ways. The Seagull 600 struggled with navigation and filtration, while the Nautilus CC lost a programmable timer and skips NanoFilters. For a more robust, hands-off clean, alternatives like the Dolphin Escape or Dolphin Cayman are worth a look.

Coverage
Looking at the Aiper Seagull 600 and the Dolphin Nautilus CC, their coverage is clearly different. The Seagull 600 is limited to the floor, so it only cleans the bottom of the pool. Its small plastic wheels and weak motors keep it from climbing inclines or walls.
The Dolphin Nautilus CC covers more. It's built for smaller in-ground and above-ground pools and reaches the floor and the walls. It can't clean the waterline, though, which is a big area for a truly clean pool.
With no navigation system, the Seagull 600 kept running into trouble in my testing. It often got stuck in one spot and left big sections of the pool untouched, which is why it scored a low 2/5 on coverage.
"Time and again, the Seagull 600 just couldn't navigate the pool properly."
The Dolphin Nautilus CC used its 50ft cord and tracks to navigate pools up to 33ft well, giving good floor and wall coverage during its cycle. It still falls short of premium models that clean the waterline, though.
The Dolphin Nautilus CC earns a better coverage score of 3.5/5. It does its intended job well but doesn't reach the waterline, which is key for a full clean. That limit matters when you weigh its overall effectiveness.
All in, on coverage there's a clear winner. The Dolphin Nautilus CC cleans floors and walls better and covers more of the pool than the Aiper Seagull 600, though both have their setbacks.
If you want a more advanced, thorough clean, look at options like the Dolphin Escape, Dolphin Cayman, or my picks for the best pool robots of 2024, all of which cover more.
Filters
The filters on the Aiper Seagull 600 and the Dolphin Nautilus CC differ a lot in design and results. The Seagull 600 uses a flat filter that came up short in my tests. It struggled to filter debris, often pushing particles back into the pool, and the design made cleanup a chore as debris piled up at the bottom of the unit.
The Dolphin Nautilus CC has a standard fine filter basket that did better in my comparison. It caught most debris and cleaned more thoroughly than the Aiper. But without multiple filter options like NanoFilters, it's limited on cloudy water and larger debris.
"NanoFilters make a real difference in filtration, and the Nautilus CC just doesn't have them."
On different debris types, the Seagull 600 struggled with both large and small particles. Its flat filter simply wasn't built to handle varied pool debris. The Nautilus CC handled standard debris well but also fell short on finer particles, since it lacks advanced filter options.
The scores show it. The Seagull 600 got a 2/5 for its poor filter and difficult upkeep. The Nautilus CC scored a 3/5 for its more effective standard basket. On filtration, the Nautilus CC is the clear winner, both on performance and ease of maintenance.
So the Nautilus CC filters better than the Seagull 600, but it still has room to grow. NanoFilters would help it catch finer particles for an even cleaner pool. Between the two, though, the Nautilus CC is the stronger option on filtration and ease of use.
Feature Set
The Aiper Seagull 600's feature set is pretty basic. Its biggest selling point is the cordless design. That sounds appealing, but the reality doesn't live up to it. It needs long charges and only gives you 90 minutes of cleaning before it has to recharge, which really limits it, especially for bigger pools or busy pool season.
The Dolphin Nautilus CC has a more reliable feature set built for better performance. With a solid 50ft cord, it cleans continuously without the charging downtime. One feature the Nautilus CC used to have but no longer includes is the programmable timer, which was great for setting up automatic cleanings.
Beyond the cordless design, the Aiper Seagull 600 has no active brush, and that's a big miss. Active brushes knock loose algae and stuck-on debris and lift cleaning a lot. Without one, the Seagull 600 leaves debris that other models handle easily. The missing navigation software makes the experience worse still.
"No active brush and no navigation software really hold the Seagull 600 back."
One of the Dolphin Nautilus CC's stronger points is cleaning both floors and walls. It runs on tracks that grip far better than the simple wheels on budget robots like the Seagull 600. Even without the programmable timer, it still comes with a 2-year warranty from Maytronics, which is reassuring on reliability and support.
"The Nautilus CC's tracks give it noticeably better floor and wall coverage."
Putting it together, the Dolphin Nautilus CC gets a feature score of 2.5/5, because it used to include a programmable timer that really helped usability, and dropping it costs it. The Aiper Seagull 600 scores a low 2/5 for its long charges, missing active brush, and inefficient design. Both have setbacks, but the Nautilus CC is the better choice for a more robust, user-friendly clean.
If you want higher performance and more features, look at the Dolphin Cayman or the Dolphin Quantum. They add automated scheduling, better filters, and wall-to-waterline cleaning, which makes them far better suited to thorough maintenance.
Conclusion
In the end, the Aiper Seagull 600 falls well short in the areas that matter, earning a disappointing overall 4/10. It can't clean beyond the floor, its filter is subpar, and maintenance is a hassle. It struggles with debris and offers very little, which makes it a poor pick for anyone wanting an efficient, thorough clean.
The Dolphin Nautilus CC scores better at 6.3/10. It has limits, like losing the weekly timer and skipping NanoFilters, but it cleans floors and walls well in pools up to 33 feet. It's more reliable and filters better than the Seagull 600, though it misses the waterline and some features newer models keep.
"The Nautilus CC wins this one, but both robots have real limits."
Between the two, the Dolphin Nautilus CC is the better choice. It has its own gaps, though, so it's worth looking at stronger alternatives for a more complete clean. Models like the Dolphin Cayman, Dolphin Quantum, or the top-rated Dolphin Premier add automated scheduling, better filtration, and real waterline cleaning.
Ultimately, if you want reliable, thorough cleaning, those alternatives give you more performance and features for a cleaner, more enjoyable pool. To see the best pool robots of the year, those models are well worth a look.
Alternate Robots
When you're shopping robots, it pays to look at the ones with more complete features and better performance. One standout is the Dolphin Cayman. It shines on automation thanks to a built-in weekly timer, so you can schedule cleanings and forget about it. It also has Hypergrip tracks and Smart Nav 2.0 for precise navigation and effective floor and wall cleaning.
Another top performer is the Dolphin Quantum. It has an XXL MaxBin for more debris capacity and NanoFilters for better filtration. Those features make it great at keeping water clear and clearing larger debris. Its Powerjet 3D mobility system also helps it navigate efficiently, covering the floor and waterline with ease.
"The Quantum's filtration and navigation are what put it a class above."
On a budget? The Dolphin Escape is a great choice. It's more affordable but still solid, with Hypergrip tracks and an active scrubbing brush. It cleans floors well, which makes it ideal for above-ground and smaller in-ground pools, and its powerful DC motors clear debris efficiently while saving energy. It doesn't have the Quantum's advanced features, but its reliability makes it a great entry-level pick.
Bottom line, if you want a more advanced, complete robot, the Dolphin Quantum is my top recommendation. Its features, bigger debris capacity, and stronger filtration make it a standout for a clean, clear pool.
