Stock filter cartridges do a great job at picking up leaves, dirt, and large debris — but they let the truly fine particles slip right back into your pool. NanoFilter Panels close that gap. They capture particles down to the micron level, including pollen, fine algae spores, suntan oils, and the cloudy "milk" that makes water look dull even after a full clean cycle.
Pairing your Dolphin Cayman with NanoFilter Panels turns it into a deep-cleaning machine. The same powerful suction, the same wall-climbing tracks, the same daily routine — just dramatically clearer water. Pool owners describe the difference as going from "clean" to "sparkling" — the kind of water that catches light and makes guests notice.
Most owners only run the NanoFilters a few times per season — after a storm, before a party, or at spring opening — which is why a single set lasts a long time. They simply swap into the same filter slots as the cartridges that came with your robot, so there's no setup, no new equipment, and no learning curve.
With code DEEPCLEAN23 the NanoFilter Panels are FREE when added with your Dolphin Cayman. This is a one-time bundle promo and cannot be combined with any other discount code (including SAVE25, SAVE50, or BUNDLE100). It's the easiest upgrade you can make for the cleanest water this season.

Easy to clean, the Cayman filters more debris than ever before. Add the optional NanoFilter™ MaxBin™ for even more cleaning power.
If you’re in the market for a high value robotic cleaner that does it all without breaking the bank, look no further than the all-new Dolphin Cayman. Given the Best Value Award by our pool experts, this lightweight yet powerful robot delivers high performance and a thorough clean every time it cleans. It possesses unparalleled power and efficiency thanks to the 24-volt DC motors driving its innovative SmartNav 2.0™ pool mapping technology and HyperBrushTM scrubbing system. The Dolphin Cayman delivers a truly deep clean you have to experience for yourself. With a full feature set and a low retail price, now is the time to upgrade.
As a part of the Max-Series™, Cayman’s easy to use and highly effective MaxBin™ filtration system sets it above and beyond what you’d expect from a standard automatic pool cleaner. Its super-fine filtration allows it to clean debris of all sizes, from algae to large leaves. Its large, oversized cartridge and programmable timer means it could clean for an entire week before it needs to be emptied.
Experince the NanoFilter difference. Side by side, you can see the difference between the NanoFilter™ (left) and standard filter (right).
For the first time ever, you can upgrade your Dolphin Cayman by adding its MaxBin™ with NanoFilters™. By adding this filter, it allows you to target and capture difficult debris that would otherwise be recirculated in your pool.
A pool cleaner that’s heavy and cumbersome makes pool cleaning a chore, but the light weight and ergonomic design of the Cayman ensures the robot bares your cleaning burdens. Its frame is ergonomically designed to create the least water resistance possible so it moves efficiently around your pool. Its light weight of only 14lbs means it’s easy to transport and drop into your pool. Plus, with its fast water release program, it never feels waterlogged or heavy when you lift it from your pool by its convenient carrying handle.
A powerful brush is a must when it comes to effectively cleaning away stuck on stubborn contaminants. The all-new Cayman features a HyperBrush™ to dislodge stuck-on debris with brushes that spin two times faster than ordinary brushes. Dirt and debris don’t stand a chance against the Dolphin Cayman.
The Cayman is equipped with HyperGrip TM Rubber Tracks to ensure that no surface gets left behind. The tracks grip tightly to your pool’s floor and walls to eliminate the slipping that wheeled robots experience. With the Cayman, the debris and tough contaminants in your pool have nowhere to hide.
The Cayman’s engineers set out to build a robotic cleaner that accomplished a thorough and efficient clean while using less energy. Their success is evident in the new Dolphin Cayman. With dual 24-volt DC motors powering the Cayman around the pool, this robot uses only 180watts, or almost 90% less than traditional cleaners that can use up to 1800 watts of power. This balance of power and efficiency ensures you get the best of both worlds every time you clean.
The Cayman cleans quick, and completes its cleaning cycles in 2 hours. Its advanced mapping system ensures that cleaning paths don’t overlap and that every inch of your pool is touched by its advanced scrubbing brushes. The Cayman features a built-in, programmable weekly timer to ensure that even if you are out of town or simply forgot, your pool stays clean and ready to enjoy.
Traditional pool robots tend to wander aimlessly around the pool, hoping they’ll eventually clean everything. With the new Dolphin Cayman, there’s no hoping or wandering involved. It’s equipped with the SmartNav 2.0™ pool mapping system to ensure that it not only cleans every inch, but it also doesn’t waste time overlap cleaning paths.
Adding the Cayman to your pool’s cleaning team means forever changing the way you view a clean pool. The Cayman pick up where other robots fall short with innovative new features that make owning a pool as easy and carefree as it should be. It’s time to see what’s different about the Cayman. Try it in your pool for 30 days, and if you’re not 100% satisfied, just return it. Let Cayman challenge everything you think about robotic pool cleaners.
Try any robot in your pool risk-free for 30 days. We believe a pool robot is an investment, and we know you'll love it. Which is why we have a 30 Day Free Trial.

John Rodriguez of "Poolbots" recommended the Dolphin Sigma for my 20x40 Saltwater pool. I have to say, "John was correct...this thing is a beast!" I live in the SoCal desert and the Sigma picks up the fine dirt, sand and phosphate residue. John answered all of my questions. Shipping was quick! Semper Fi — USMC 1984-1992
"Patient, knowledgeable, and took the time to answer all of my questions thoroughly."
Jose provided clear and detailed information about the pool cleaners. His professionalism made the whole process stress-free.
I wish I would have converted my pressure side vac to an electric pool robot a long time ago. It cleans 10x better and completes my pool in 90 minutes.
"Without her multiple emails to the company, this would never have happened."
Shannon assisted me with an ongoing issue since May 2025 with a manufacturer. She went the extra mile and followed up!
Excellent customer service and super fast shipping. I highly recommend Poolbots for all your needs.
"I asked to speak to a human — and was told 'I am a human!'"
I clicked "chat" expecting AI. I was so pleased this company still has human interaction. John was great.
I really appreciate the opportunity to try a robot and be able to swap it. Great return process and customer service.
"A far better and more informed purchase option than Amazon."
John went out of his way to go over all the different units and what might be best for my pool. Absolutely awesome customer service.
"Truly treats you like family."
I had a few issues with my product, but Jose did an amazing job helping me and stayed in constant communication throughout the entire process.
"Jose helped fix my incorrect shipping address... saved me a lot of grief."
His help was excellent. Quick intervention prevented a lost shipment.
"Because of John, I bookmarked Poolbots and will use them for everything."
He was very knowledgeable, professional, and interested in getting you the right product — not just making a sale.
"John was amazing. I had no idea what I needed."
He was very patient. After giving me multiple options and explaining the differences, he offered the perfect unit for my pool.
"Call John, you won't be sorry!"
John guided me through the process of selecting the best pool cleaner robot for my needs. Very highly recommend!

The Cayman is AWESOME. The tracks work so much better than wheel or tires in other Bots and the snap filter in the Cayman works flawless.
Works like a charm. Very happy. Hand-free clean pool
What a great little robot. We gave it a big job and it just keeps working. Very pleased. 50,000 gallon saltwater pool, with 10,000 gallon zero edge overflow tank. We just drop it in both and it cleans everything. Walks up the sidewalls, even crawls up on in pool steps and cleans them.
Cleans our 26k salt water pool with ease, easy to clean filter. Easy to use, and cheaper than the same model at our local pool store. We had a Pentair in pool cleaner that we replaced with this model. This cleaner is much easy to clean, and does a great job picking up various debris from the pool floor, it is able to climb the side walls, and occasionally can make it on to the steps. We usually put it in the pool for about 2hours a couple times a week depending on season, and need.
Best I have ever owned. Replaced my old polaris.
No, we never charge a restocking fee ever! We know a robotic pool cleaner is a big investment, which is why we offer Free 30-Day Trials on all robotic pool cleaners!

If your Dolphin Cayman is not cleaning the pool properly, try checking the filter bag for any debris or blockages. Also, check the brushes and tracks for any damage or wear. If you are still having issues, contact Maytronics customer support for further assistance.
The handles on your Dolphin are for lifting and carrying the unit, while the floats are designed to help your Dolphin navigate around the pool and maintain proper buoyancy.
To remove any debris or obstructions from your Dolphin's tracks, turn off the power supply and carefully remove the tracks from the unit. Use a soft brush or cloth to clean the tracks and remove any debris. Once clean, reattach the tracks to the unit.
