Discover a new level of pool cleanliness with the Dolphin Sigma robotic pool cleaner.

Efficient cleaning

Gone are the days when you had to struggle with a pool cleaner for hours and still miss cleaning some areas. The Sigma uses CleverClean technology which comprises scanning software and advanced navigation systems.

You’ll be amazed at how your Dolphin Sigma robotic pool cleaner paves its way around the pool cleaning every inch of the pool’s floor, waterline and floor. And you will not have seen it all until you watch it smartly navigating around obstacles and swiftly returning to its route.

Power! Power! Power! No stalling at all

DC motors are known for their high torque to inertia ratio. The ones used to control the Sigma perform beyond the documented capacity.

But what else would be expected from a triple high RPM DC motors arrangement? Exceptional efficiency and a continuous power operation are the best ways to describe this pool cleaner.

The heavy-duty pool cleaning tasks this robotic pool cleaner performs require high power level. These three DC motors faithfully deliver high power, and they do so in the most efficient manner to ensure that less energy is used to do more.

HyperGrip continuous tracks

In a bid to reduce slipping and energy efficiency losses, the sigma uses continuous rubber tracks instead of wheels. Your Sigma unit holds on to the pool’s surface, whether vertical or horizontal like it would want to live there.

But the constant contact is not for nothing. More contact means that the brushes have more opportunities to scrub and clean the surfaces.

Traction is further enhanced by the cleaner’s high grip, geometric shape, and water-optimized tread. These minimize the rolling resistance significantly and enable more effective weight distribution and wall climbing.

Highly optimized scanning and coverage

Dolphin set a new benchmark for other pool cleaning equipment using the Sigma. This robotic pool cleaner uses a unique scanning and coverage technology called SmartNav 3.0. This tech determines the optimal pattern to be followed by the Sigma for faster cleaning.

Combining this technology with the gyroscopic control system, no dirt will hide from this cleaner. And to push cleaning efficiency a notch higher, the gyro system informs the cleaner about where it has and has not been to avoid overlapping cleaning paths.

Even more intriguing is the unit’s ability to sense drains and ladders. The frustrations of having a cleaner that constantly hangs on obstacles are a thing of the past with the arrival of Sigma’s smart navigation systems.

It’s the right pool cleaner for stubborn contaminants

Most common robotic pool cleaners are able to remove loose dust particles and debris. Current day pool cleaning demands better designed and powered pool cleaners to extract even more sticky substances from the pool’s surfaces.

The Sigma is designed with PowerClean dual scrubbing brushes that make cleaning difficult-to-remove contaminants seem like a breeze. You will no longer have to worry about bacteria, algae, and biofilm making your pool unhygienic and turning pool maintenance into a nightmare. Have the Sigma by your side and enjoy the benefits of efficient deep pool cleaning.

Large top-loading cartridge filtration

The cartridge filters on the Sigma are large and easy to clean. These cartridges are the biggest ever seen on a robotic pool cleaner. Their massive cavities allow you to remove debris and fine dirt quickly, and this makes maintaining the pool cleaner easy.
