The Dolphin Transformed.

Meet the Latest Step in Our Journey

Progress. It’s behind everything we do. It’s why we’re always developing new technologies to revolutionize automated pool cleaning. The engineers created new motors and drive systems that deliver improved performance and higher energy efficiency. State-of-the-art DC motors and an ingenious ergonomic design deliver an exceptional user experience while reducing energy use up to 90%. The all-new Dolphin Sigma is the very latest step on our journey of progress. It’s one that brilliantly reflects the engineering expertise that has gone into its development. And it's easy to see why the new Dolphin Sigma is the answer to the changing demands of pool owners everywhere.

Designed from Scratch. Pushed to the Limit.

You can only reach new peaks if you’re willing to push your limits.

Yet again, everything comes back into play. It’s about a new benchmark. We are always looking forward. Not sideways, never back. We started from scratch. And we gave everything we got to make the newest Dolphin even better. Our goal was simple. To create the next Dolphin that can do more, deliver more and consume less power than ever before. The Sigma represents the future of the Dolphin brand. A fascinating future that shows what’s possible. Its design is completely new, but like that of every Dolphin that came before, it’s based on years of research and engineering. The all-new Sigma takes its place at the top of the Dolphin line and in the top echelon of its class.

Powerful in All Conditions

Superior Surface, Wall and Waterline Cleaning

In a radical departure from ordinary cleaners, the Sigma pool cleaner was designed to clean all pool surfaces including the tile and waterline with pinpoint precision. For the first time ever, a consumer robot is equipped with an advanced Gyroscope to deliver precise control and positioning of the robot. While other cleaners fall from the wall, the all-new gyroscope and triple 3,000 RPM DC motor allows Sigma to remain firmly planted against the wall all the way to the top. Sigma Dolphin pool cleaners reaches every square inch of the pool as high speed spinning brushes handle difficult colonies of bacteria, algae, and biofilm. Sigma reaches deep inside pool corners, scrubs, and vacuums so you don't have to.

Triple High RPM DC Motors

Ultra-Efficient using 87% Less Energy

Famous for a high ratio of torque to inertia, the DC motor can provide up to five time it's rated torque without stalling. The Sigma Dolphin pool cleaner utilizes not one, not two, but three onboad DC motors. The revolutionary 24 volt DC motors require 87% less energy than the AC motors that power old fashioned pool cleaners. Efficiency demands power. That was the principle then. And it still stands today. There was an opportunity to get more from less. To optimize the work input to work output. Enter the era of gyroscope enabled robotic pool cleaners.

Dual Scrubbing Brushes

Obliterate Stubborn Dirt & Contaminants

There are few pool cleaners that are capable of cleaning your pool in a truly satisfying way. It started with a vision. A vision to completely reimagine what we expect from a robotic pool cleaner. Traditional cleaners have no brushes that contact the pool surface. We gave Sigma not one, not two, but three powerful brushes. Engineers gave Sigma dual spinning brushes that power scrub the pool surface and a third center CleanSweep™ brush that rapidly oscillates back and forth to dislodge stubborn contaminants. Together, the triple brush systems provides exceptional agitation and brushing performance.

In addition to vacuuming loose debris, the new Sigma really shines when it comes to difficult to remove contaminants like algae, bacteria, and biofilm that’s firmly attached to the wall of most pools. There are 21,000 known varieties of algae. Chances are, you’ve dealt with at least a few of them. Resistant to chlorine, biofilm is self-perpetuating and very difficult to remove. Traditional pool cleaners only pick up loose contaminants, leaving stubborn contaminants stuck to the pool wall. But the Sigma attacks stubborn contaminants at their core. Biofilms in swimming pools can and often do lead to cloudy water, algae blooms, scale build-up, and even corrosion. Traditional pool sanitation focuses on tr
