NanoFilters™
Often overlooked, having a NanoFilter™ can be the most important part of a pool robot. Without it, small microscopic particulate will pass right through the standard filters found on most robots. These highly advanced filters capture more debris than any other filter on the market, leaving you with a cleaner, happier, and healthier pool.
The Dolphin Sigma includes NanoFilters™
The Dolphin S200 does not include NanoFilters™
Standard Fine Filter
These standard filters help capture larger items such as small leaves and other debris, while maximizing flow rate. However, if your pool struggles with cloudy pool water, small algae, or sand. You many want to consider a unit with NanoFilters™.
The Dolphin Sigma includes a standard filter.
The Dolphin S200 includes a standard filter.
Programmable Weekly Timer
An automatic pool cleaner should be automatic, right? With a programmable weekly timer, you can set the robot to clean at different intervals. So your pool robot can clean for you everyday of the week while you sit back and relax - without the need to manually turn it on and off everyday.

Dual Stabilizer
This essential piece to waterline cleaning allows the unit to cling to the walls of your pool - allowing a more precise and deeper clean at the waterline. Units with dual stabilizers have increased performance and agility while cleaning. It also doubles as an easy handle to pickup your robot from.

Say goodbye to pesky tangled cords. An anti-tangle swivel allows the robot to move 360 degrees around your pool without the cord getting tangled. So you can sit back and enjoy while your pool robot vacuums and cleans for you.
