Introduction
I bought both the Dolphin Cayman and the Dolphin Escape with my own money and ran them for months, because these two get mixed up constantly and they really shouldn't. They sit in the same mid-range price bracket, but they're built for different pools and different owners. Both cleaned well. Where they split is what I want to walk you through.
The Cayman is the more automated of the two. It's got a weekly timer, strong scrubbing brushes, and it's easy to haul in and out of the water. In my testing the Smart Nav 2.0 mapping kept it moving in a sensible pattern instead of bouncing around at random, and that's a big part of why it covered my pool as evenly as it did for a robot at this price.
The Escape is a different animal. It was designed for above-ground pools, and it's genuinely good at that job, but it also held its own in a small in-ground pool when I tried it there. The Hypergrip tracks and that beefy scrubbing brush chewed through debris that I honestly expected to give it trouble. The catch, and it's a real one, is that it does not clean the waterline. If your tile line is where the grime collects, that matters.
I ran both through a bunch of cleaning cycles in different pool conditions, from a light dusting of dirt to the aftermath of a windy weekend. If you want the full story on either one, I wrote up the Dolphin Cayman and the Dolphin Escape separately. Both were a pleasure to test, and each has a clear lane, which makes for a fun head-to-head.
Below I'll break down exactly how I tested them and how each one did on pool coverage, filtration, and features and warranty, so you can figure out which one fits your pool.
How We Test
I put both the Dolphin Cayman and the Dolphin Escape through the same routine, and both earned their keep. Over roughly three months I judged them on the three things that actually matter day to day: how much of the pool they clean, how well they filter, and what you get in features and warranty.
"Set the Cayman on a schedule and it just handles the pool for you."
The Cayman is where automation earns its price. Smart Nav 2.0 walked it through my whole pool, floor to walls, without leaving the obvious gaps cheaper robots leave. Between the HyperBrush and the HyperGrip tracks it had real scrubbing muscle, and it popped loose the stuck-on stuff near my steps that I usually have to hit with a brush by hand. Cycle after cycle, it just kept covering the pool the same reliable way.
The Dolphin Escape is tuned for above-ground pools, but I dropped it into a smaller in-ground pool too and it handled that fine. It runs the same Smart Nav 2.0 mapping, has strong motors, and those HyperGrip tracks kept it planted even in the trickier corners. It pulled up tough debris again and again. The one thing it flat out won't do is clean the waterline, so keep that in mind.
Filtration got the same attention. The Cayman uses a big MaxBin, a noticeable step up from the little filters on the first-gen Dolphins, so it holds a lot more before you have to empty it. Pair that with the optional NanoFilters and my water stayed clear the whole time I ran it. The basket also pops out and rinses off without a fight, which you appreciate more than you'd think.
The Escape carries a large filter basket too, and it grabbed both the big stuff and finer particles well enough for normal cleanings. It doesn't take the NanoFilters, but for standard debris the basket was plenty. Both robots kept the water clear across my whole test window.
On features and warranty, the Cayman's programmable timer is the standout. You set a weekly schedule and the robot runs itself, which is exactly what you want if you'd rather not think about it. The Escape skips the timer and leans into plug-it-in simplicity instead, and there's a real audience for that. Both ship with a 2-year warranty from Maytronics, so you're covered for a good while either way.
After three months, my read is simple: both robots are strong picks for the pools they're aimed at. The Cayman wins on automation and all-around performance, while the Escape is a reliable, powerful cleaner for above-ground and smaller in-ground pools. Want the deep dives?

If you're shopping the mid-range, both of these give you solid value and something you can trust. I test this stuff so you don't have to gamble on it. Check back with me and the PoolPad team for more real-world testing and pool-care tips.
Coverage
On pool coverage, both the Dolphin Cayman and the Dolphin Escape hold their own, but they're playing different games. The Cayman is built to clean the floor and the walls, so you get a fuller clean of the whole pool, not just the bottom.
Smart Nav 2.0 keeps it on a deliberate path instead of the random bounce-and-hope routine, so it isn't re-cleaning the same three feet while ignoring a corner. In my pool that meant even coverage and no obvious dead spots, and it held up in bigger pools too.
The Escape puts its energy into powerful floor cleaning, specifically for above-ground pools. With its HyperGrip tracks and strong scrubbing brushes, it clings to the floor and clears debris without slipping around.
Here's the dividing line, though: the Escape doesn't do the waterline. Unlike the Cayman, it won't climb up and clean that tile band, and if you need full top-to-bottom coverage, that's going to bug you.
"Wall cleaning is where the Cayman pulls ahead - plain and simple."
Scores land where you'd expect. The Cayman takes a 10/10 on coverage and the Escape gets an 8/10. That gap is the wall and waterline story in a nutshell: the Cayman handles the more complicated surfaces, the Escape sticks to the floor.
Both clean well, no argument. But the Cayman's ability to work the walls makes it the more complete cleaner across more pool types. If you want one robot that covers the whole thing, that's the one.
Filters
Both the Dolphin Cayman and the Dolphin Escape filter well, but they get there differently. The Cayman uses a standard fine filter basket that grabbed a wide mix of debris in my runs. It's large, it slides out easily, and it rinses clean fast, which keeps upkeep painless.
What I really like about the Cayman is that it takes the optional NanoFilters. Those catch the microscopic stuff the standard basket lets slip through, and that's the difference between okay water and genuinely clear water. If your pool goes cloudy from fine debris, that upgrade earns its spot.
The Escape also runs a large filter basket. Like the Cayman's, it handles both the bigger debris and finer particles, so it covers a solid range of cleaning jobs. Pulling it out and cleaning it is just as easy, so no complaints there on maintenance.
The real split is the NanoFilters. The Escape doesn't support them, so it's a bit less capable with the truly fine stuff like sand or algae. For straightforward above-ground cleaning it's more than enough, but if you regularly fight fine debris, it can't match the Cayman's ceiling.
On the filtration numbers, both land at 4.0 out of 5. They're evenly matched on paper, but the Cayman's NanoFilter option gives it more headroom when you need to chase down the finest particles for that last bit of clarity.
"Add the NanoFilters and the Cayman keeps my water noticeably clearer."
Both handle a range of debris just fine. But if your priority is the clearest possible water, the Cayman's flexibility and its knack for fine-particle filtration give it the edge.
Feature Set
The Dolphin Cayman and the Dolphin Escape both come loaded for their jobs, but they're aimed at slightly different buyers. Both are dependable robots; the difference is how much they do for you versus how simple they keep things.
The Cayman leans into automation in a way you don't usually see at this price. The headline is the programmable weekly timer: set your schedule once and the robot runs itself all week. For an entry-level model, that's a genuinely nice thing to get.
The Escape goes the other direction. No programmable timer, just plug it in and go. If you'd rather skip the settings and get a straightforward, no-fuss cleaner that still cleans hard, that's the appeal.
A big part of the Cayman's strength is the HyperBrush and HyperGrip tracks. Together they give it real scrubbing power and the grip to work both the floor and the walls, which is exactly why its coverage came out so strong in my testing.
"The Cayman's HyperBrush digs in and actually scrubs."
The Escape brings its own HyperBrush scrubbing and Smart Nav 2.0 mapping, so it navigates and cleans efficiently too. It won't climb walls, but it doubles down on floor coverage instead, and for above-ground pools that focus pays off.
On day-to-day usability, the Cayman scores well thanks to the MaxBin, which boosts how much debris it holds and how well it filters. The basket is efficient and comes out for cleaning with basically no effort, so you're not fighting it after every run.
The Escape also has a large filter basket that takes on a mix of debris sizes. It doesn't get the NanoFilters the Cayman offers, but the basket still filters well enough for standard cleaning and kept my water clean during testing.
Warranty is a tie: both carry a 2-year Maytronics warranty, so you're covered long-term either way. The Cayman's extra automation and easier handling just nudge it ahead of the Escape overall.
The feature scores line up with all that. The Cayman takes a 9.4 out of 10 on the strength of its automation and usability, while the Escape earns 8.7, shining on simplicity and no-fuss operation, especially for above-ground pools.
Both do their jobs well, but the Cayman is the pick if you want a more automated, easier-to-live-with robot. For the full breakdown and more head-to-heads, check out my complete reviews of the Dolphin Cayman and the Dolphin Escape.
Conclusion
Between these two mid-range Dolphins, both clean well, but they answer different needs. When I add up my testing, the Dolphin Cayman lands at 9.4 overall and the Dolphin Escape comes in at a still-strong 8.7.
My pick is the Dolphin Cayman. The automation is what wins it: the programmable weekly timer means you set a schedule and stop thinking about it, and Smart Nav 2.0 plus solid filtration, including the optional NanoFilters, make it the better fit if you want a thorough, mostly hands-off clean.
"The Cayman's automation is what pushes it over the top for me."
The Escape isn't a consolation prize, though. It's a reliable, powerful cleaner, especially for above-ground pools. Simple to run, strong motors, Smart Nav 2.0 mapping - it's a real competitor. It skips the waterline and the timer, but on floor cleaning it delivers, no question.
If your needs run higher, like full pool coverage with waterline cleaning, look at step-up models such as the Dolphin Premier or the Dolphin Sigma. They bring more advanced features and better warranties for a more complete, lower-effort clean.

Alternate Robots
If you're weighing other mid-range robots, a couple more are worth a look. The Dolphin Quantum stood out to me for its cleaning power. It packs a larger XXL MaxBin and includes the NanoFilters out of the box, so filtration is its strong suit. If your pool fights fine debris or turns cloudy on you, the Quantum's NanoFilters pull in even the tiny particles.
Then there's the Dolphin Premier, which I call the best pool robot for leaves. It comes with a full set of filter options: a standard fine filter, NanoFilters, and an oversized leaf bag that's unique to this model. It handles a wide range of jobs, cleaning the waterline and pulling in leaves and larger debris with strong suction. If you want one robot that does it all, it's worth the spend.
The Aquabot REVA deserves a mention too. It uses a gyroscope for steadier, more precise navigation, and it cleans the whole pool, waterline included. It runs dual-layer filtration, so it's efficient with both big debris and finer particles, and it adds app connectivity so you can control and schedule cleanings right from your phone.
"If clear water is the goal, the Quantum is the one I'd hand you."
So while the Dolphin Cayman and Dolphin Escape are both strong mid-range cleaners, the Dolphin Quantum and Dolphin Premier bring extras that might suit you better. Both are capable robots that clean the whole pool thoroughly. To see more options side by side, head to my best pool robots page for the full lineup of reviews and comparisons.
