The Tile & Waterline Expert
Over 90% of bacteria and algae in a typical pool is attached to the wall, with the highest concentration found where the water stops on the wall. You may have heard this problematic area referred to as the scum line. This area just above and below the waterline is known to harbor the heaviest concentration of bacteria, algae, and biofilm. In the past, pool robots advertised as wall cleaning only cleaned the lower wall. They’re simply not capable of reaching the upper wall and tile line.
A New Level of Clean
Dolphin Engineers firmly believe in the laws of physics. And defying them time and time again. To enable Premier to climb to the hard-to-reach waterline, Dolphin engineers gave Premier Vector Climbing. You may have noticed unique dual stabilizers that gives Premier it’s friendly, approachable look. But it’s not for looks. It’s the secret to maintaining position on the upper pool wall. Premier attaches to the wall and maintains position, even with up to 40% of the robot above the water. The result is an engineering milestone and a whole new level of tile and waterline performance never before seen in a pool robot.
"The Best Kept Secret in Pool Robots: The Dolphin Premier"
Read the Dolphin Premier Review →Introducing Multi-Media™
The latest innovation from Dolphin. Most robotic pool cleaners settle for one type of filter media. But different kinds of debris call for different types of media. For the first time ever, you don’t have to compromise.

Larger Commercial-Grade Motors
The efficiency of the Premier does not compromise power. Dolphin engineers gave Premier larger, more powerful motors borrowed from the commercial line of robots. These heavy duty motors are 20% larger, providing the powerful suction force needed for larger debris. Prone to slip and wear out prematurely, drive belts have been replaced with a new direct drive system. Ordinary wheels have been replaced by HyperGrip™ dual tracks. These high performance rubber tracks reduce slippage up to 40% and help take efficiency to a whole new level. Watch Premier’s powerful dual motors at work when it cleans the waterline. To effectively scrub this area, the cleaner must have enough power to rise above the waterline while maintaining contact with the wall. While some cleaners only vacuum loose debris, Premier scrubs and cleans the pool surface with two powerful spinning brushes - dislodging dirt, debris, biofilm and other contaminants. More power enables a whole new level cleaning.
Weekly Smart Timer with Media Alert™
Premier requires just 3 hours for a complete cleaning cycle. For most pools, there’s no need to run Premier every day -- 2-3 times per week is all it takes. MediaAlert™ monitors the onboard media and flashes an LED light when it’s at capacity. This indicator light lets you know when it’s time to clean Premier’s filters it can get back to work quickly. Some entry level robots require you to manually turn your robot on. Premier’s weekly smart timer turns Premier on and off automatically at the desired frequency – whether that’s daily, twice a week, or three times a week.
Anti-Tangle Swivel
You don’t need to be an engineer to understand the benefits of tangle-free operation. A swivel ensures that your cable won’t get tangled or knotted, so you can put the best robotic pool cleaner in your pool and not have to monitor it. What other robotic pool cleaner company offers a swivel? Only Premier Dolphin pool cleaners.
SmartNav 2.0™
It’s no secret that intelligent robots are the future. That’s why Dolphin engineers developed SmartNav™ technology. Unlike ordinary pool cleaners that wander around the pool aimlessly, Premier is smart and logical. With microprocessor controlled SmartNav, the optimal pattern is calculated for faster cleaning and better efficiency. If you would rather take control, choose the optional wireless remote control. Great for spot cleaning and fun, the wireless remote provides hours of entertainment for both kids and kids at heart.
D9 Microprocessor
When you unleash the Dolphin Premier automatic pool cleaner into your pool, it finds the fastest, most thorough path and cleans it with unparalleled precision. Smart-Nav software scans and calculates the optimal pattern for faster cleaning and improved efficiency. With the ability to sense ladders and drains, Dolphin pool cleaners won't get hung up like ordinary cleaners. Microprocessor controlled pool scanning makes the Dolphin Premier deliver a smarter pool cleaning experience.
The Best of the Best.
HyperGrip™ Rubber Tracks
Wheels aren’t going to cut it. In pool water, it is easy for wheels to slip resulting in wasted energy and poor performance. The HyperGrip track system is designed to scale the walls of your pool with unmatched agility. The much greater surface area of a rubber track improves directional control and delivers substantially more force than wheels. The Premier pool robot features aggressive rubber tracks for superior power delivery, better control and precise tracking. When wheel slippage is eliminated, energy is conserved.
The Ultimate Cleaner
From day one, Dolphin engineers developed robots with a sharp focus on efficient performance. Because of this philosophy, Dolphin has delivered the most advanced tile and waterline robot ever. Combined with MultiMedia™ Filtration, the Dolphin Premier stands alone as the most powerful, most advanced, and most efficient robotic cleaner ever created. Efficient performance is not a trend at Dolphin; it’s a way of thinking. That was the principle then. And it still stands today.

I must say the Dolphin Premier Robotic Pool Cleaner with Caddy & Wireless Remote is for me. I looked at every Robotic Pool Cleaner and did not find one that can match this one. With all the standard features it has, the performance it gives you and the 3 year full warranty, it is hands down the best in the industry. The service you receive is the BEST and they're so helpful in every way. I highly recommend this product. If you want the best, go with the Dolphin Premier Robot

I'm in love with the Dolphin Premier. Since I've purchased I've really been pleased with its performance, and my pool is super clean. It is able to clean up to the waterline, and I haven't had problems with it getting tangled. Great buy!
4 out of 5
my swimming pool has been around for awhile and I've used several different cleaners but the Dolphin Premier has been one of the better ones out there, as far as robotic pool cleaners go. it's been the easiest to use, since all I have to do is just drop it in the water and let it go.
