Introduction
The Aiper Seagull 1000 and the Dolphin Cayman are two very different robots, and comparing them is genuinely useful because they sit at opposite ends of what you'd expect from a pool cleaner. I bought both and ran them in normal pool conditions to give you a straight read on how each performs and holds up.
The Seagull 1000 grabbed my attention with its cordless design and low price. But once I got into it, the drawbacks piled up. As I laid out in my review, it has no active brush, an unreliable battery, and weak filtration, and it scored just 4/10 overall. The price is nice; the performance and longevity aren't.
The Dolphin Cayman is the opposite kind of story, a real standout in the mid-price range. I covered its strengths in my review: a weekly timer, the MaxBin filtration system, and strong wall-climbing. It scored an excellent 9.4/10, which makes it a top pick if you want strong cleaning without paying a fortune.
Overall, the Cayman impressed me with thorough coverage, easy maintenance, and programmable scheduling. It doesn't do waterline cleaning, but it's good enough everywhere else that the miss barely registers.
These two aren't really competitors so much as a lesson in what a few extra dollars gets you. The Seagull 1000 is a budget floor-crawler; the Cayman is a proper mid-range robot with scheduling, wall climbing, and a real filter. I'll walk through each area, but the short version is that the Cayman earns its price and then some.
Put it together and the picture's clear: the Seagull 1000 might do for someone on a tight budget, but the Dolphin Cayman is the far better buy if you want a reliable, automated cleaner. It's easier to use, it cleans better, and it earns its price over time.
How We Test
At Pool Pad, I put every robot through the wringer before I'll make a recommendation. Each one runs in my pool for three months so I get a full read on performance and reliability, not just a good first day.
With the Aiper Seagull 1000, I looked hard at coverage, filtration, and features. Coverage was the first problem. It's floor-only, with no real navigation software and plastic wheels underneath, so it kept missing spots and had no way to map the pool or grip inclines.
Filtration wasn't any better. The flat, fine filter couldn't capture debris efficiently, so the results were disappointing. Next to robots with proper multi-layered filtration, it's just outclassed.
The Dolphin Cayman went through the same tests and it was a different experience entirely. On coverage, it cleaned from the floor up the walls with ease. Between its strong brushes and Hyper-Grip tracks, it moved around the pool confidently and stayed consistent the whole three months.
Filtration was where the Cayman really pulled ahead. The MaxBin's big capacity and optional NanoFilters meant excellent debris collection and clean water, and it made maintenance simpler than the Seagull 1000 ever managed.
"For a mid-priced robot, the Cayman sets the bar."
I also weighed features and warranty on both. The Aiper's cordless design sounds nice but left it short on battery and power for real cleaning. Its one-year warranty didn't help, especially with plenty of owners reporting battery trouble after just a season.
The Dolphin Cayman came with a programmable power supply, so I could schedule cleanings without lifting a finger. Its two-year warranty added real peace of mind and told me the maker actually trusts the product.
All told, testing both made the Cayman's advantages obvious. It's the one I'd point you to for a reliable, efficient robot. For more strong options, take a look at my best pool robots page.
The programmable power supply on the Cayman is one of those features that quietly changes the experience. Set it once and the pool just gets cleaned on schedule, no dragging the robot out and starting it by hand every time. That, plus the two-year warranty, is the kind of thing that makes a robot feel like an appliance instead of a chore.
My whole aim is to make your decision easier with reviews you can actually use. Stay tuned to Pool Pad for more honest reviews and picks to keep your pool clean and healthy.
Coverage
On coverage, the Aiper Seagull 1000 and the Dolphin Cayman couldn't be more different. In my testing, the Seagull 1000 stuck to the floor and couldn't clean walls or the waterline. Blame the plastic wheels and the lack of navigation software, which left it missing spots and covering the pool inefficiently.
The Dolphin Cayman is a different beast. Unlike the Aiper, it has Smart Nav 2.0 software and HyperGrip tracks, so it moves around the pool efficiently and climbs walls with ease. That means it covers a lot more of the pool and misses far less.
One of the Cayman's real strengths is going from floor to walls, thanks to strong brushes and precise navigation. It doesn't clean the waterline, worth being upfront about, but it still covers far more than the Seagull 1000's floor-only routine.
On efficiency, the Cayman is well ahead. It runs a calculated path via Smart Nav 2.0, so nothing gets skipped. The result is a more precise, more complete clean.
"For a mid-priced robot, the Cayman sets the bar."
The scores line up with what I saw. The Seagull 1000 earned a 4/10, held back by floor-only coverage and no navigation. The Dolphin Cayman hit a 10/10, reflecting how much more of the pool it cleans and how little hand-holding it needs.
Worth being clear-eyed here: the Cayman doesn't clean the waterline, so if that band is your biggest pain point you'll want to look higher up the range. But for cleaning the floor and walls thoroughly and consistently, it's exactly the kind of coverage most pool owners actually need day to day.
The Seagull 1000, by contrast, gives you floor-only coverage that isn't even reliable, so you're left topping up by hand. For most inground pools that's simply not enough robot.
On coverage, the Dolphin Cayman is simply the better robot. Its features deliver a thorough, reliable clean, which makes it the pick if you're investing in something good. The Seagull 1000 is cheaper, but its coverage is too limited to keep a pool properly clean.
"A clear winner in robot performance"
Filters
The filtration on the Aiper Seagull 1000 and the Dolphin Cayman is a real dividing line, and it shows up in how clean each one leaves the pool. The Seagull 1000 uses a flat, fine filter that I found weak in testing. That single-pane design couldn't hold the smaller particles and let them wash right back into the water.
The Dolphin Cayman comes with the MaxBin filtration system, and it's a different world. It's a large-capacity basket that holds more debris, and it takes optional NanoFilters that seriously boost its ability to grab fine particles.
I'll take the Cayman's filtration every time. The MaxBin's bigger capacity and the NanoFilter option mean better debris collection and simpler upkeep. In my experience it grabs everything from big leaves down to microscopic particles, and the water clarity reflects it.
The Seagull 1000 couldn't come close. Its flat filter couldn't hold large debris well, and the small stuff kept escaping back into the pool, which meant more cleaning by hand. That was a big mark against it in my book.
The Cayman's filters are also easier to clean and more effective. Multiple layers of filtration, including the NanoFilters, catch even the smallest debris, so the water stays clear and free of the stuff you don't want in it.
The scores say it plainly. The Seagull 1000 scored a mere 2/5 for its basic, ineffective filtration. The Dolphin Cayman earned a strong 4/5, which reflects how well it handles a range of debris sizes and keeps the water clean.
"The Cayman's filtration is in a completely different league."
The MaxBin is also just easier to live with. It pops out from the top, rinses in seconds, and holds enough debris that you're not emptying it every single run. Set that against pulling the Seagull 1000 apart to reach a flat filter, and the Cayman wins the maintenance battle as decisively as it wins the filtration one.
So on filtration, the Dolphin Cayman wins outright. Its MaxBin and optional NanoFilters give you a thorough clean and easier maintenance, which is real value for a pool owner. If efficient, thorough filtration is what you're after, the Cayman is my pick.
Feature Set
Comparing the feature sets of the Aiper Seagull 1000 and the Dolphin Cayman, the gap is striking. The Seagull 1000's cordless design looks convenient on the surface, but in use the short battery, around 90 minutes of run time, means frequent charges and limited cleaning windows.
The Dolphin Cayman, on the other hand, shines with a programmable timer that cleans your pool on a set schedule. That cuts out the manual work and makes it a genuinely automated robot. The Cayman's feature score is a strong 4.5/5 against the Aiper's 2/5, and that automation is a big part of why.
The Seagull 1000 may be cordless, but it has no active brush, which really hurts its cleaning. It relies on a small static brush that barely scrubs. The Dolphin Cayman uses HyperBrush technology that spins twice as fast as a typical brush, so it scrubs off debris and algae efficiently.
The Cayman also runs on HyperGrip tracks instead of plastic wheels, which grip pool surfaces better and let it clean thoroughly from floor to walls. Those features drive its cleaning and its easy upkeep, which is exactly why its feature score is so much higher.
"The Cayman's features are what make it a genuine standout."
The Cayman also carries the large MaxBin filtration system with optional NanoFilters, giving you better debris collection and fewer filter cleanouts. The Seagull 1000, by contrast, uses a basic flat filter that couldn't catch smaller particles in my tests.
Warranty is another split. The Seagull 1000 comes with a one-year warranty, which is short, and during my review I saw plenty of owner complaints about battery failures right around that one-year mark. The Dolphin Cayman offers a more reassuring two-year warranty backed by Maytronics support.
On features, the Dolphin Cayman is far ahead. The Aiper's cordless design and lower price look appealing at first, but the Cayman's programmable timer, HyperBrush, and MaxBin filtration make for a complete, user-friendly, genuinely effective cleaner.
Add it all up, the weekly timer, the HyperBrush, the HyperGrip tracks, the MaxBin, and the two-year warranty, and the Cayman isn't just better on paper, it's better in the moments you actually interact with it. The Seagull 1000's lone trick is being cordless, and that trick costs you power, run time, and cleaning quality.
Those features plus a longer, more reliable warranty make the Cayman the better long-term buy. If you want to keep exploring, my best pool robots list has more top picks across price ranges.
Conclusion
Wrapping up, my testing of the Aiper Seagull 1000 and the Dolphin Cayman shows a wide gap in performance and reliability. The Seagull 1000 scored a low 4/10, reflecting its limited coverage, weak filtration, and lack of real features. The Dolphin Cayman scored an impressive 9.4/10, thanks to its strong cleaning, advanced filtration, and easy-to-use features.
Head to head, the Dolphin Cayman clearly beats the Aiper Seagull 1000. Its coverage, features, and reliability make it the better buy for anyone who wants a dependable, efficient robot.

Alternate Robots
As we go through these comparisons, it's worth putting a few other strong robots on your radar. Two that stand out for reliable, thorough cleaning are the Dolphin Premier and the Aquabot REVA, each with its own set of strengths.
The Dolphin Premier is a top-tier robot with excellent cleaning. Its headline feature is Multi-Media filtration, which includes standard filters, NanoFilters, an oversized leaf bag, and disposable debris bags. That versatility means it handles any kind of debris, from big leaves to fine particles. The Premier also excels at waterline cleaning, thanks to its dual stabilizer and strong motors.
Another strong one is the Aquabot REVA. It modernizes the whole process with a gyroscope and smartphone app control. The gyroscope keeps its navigation precise and balanced, so it cleans efficiently, and it covers the waterline, an area lesser robots skip. Its dual-layer filtration doesn't include NanoFilters, but it still cleans thoroughly, catching both large debris and fine particles.
If you need the most versatile, powerful filtration, the Dolphin Premier is the one to beat, with filter options that keep a pool spotless. If you love smart tech and app control, the Aquabot REVA brings genuinely useful modern features, though it trails the Premier a bit on filtration capacity.
"For versatile, powerful cleaning, the Dolphin Premier is hard to top."
Between these two, pick by what your pool throws at you. The Premier is the one for heavy leaf load and full-pool coverage including the waterline, while the REVA is the pick if app control and gyroscopic navigation appeal to you. Both are a big step up from a basic floor-crawler.
The point is that there are plenty of strong contenders, each with its own edge. The right one depends on your pool and your priorities. To dig deeper into these models and see other top picks, check my best pool robots page, where I cover options for a range of needs.
