Smart Features 

When I refer to Dolphin Sigma as the automatic pool cleaner, it amazes me with its smart features that combine technology and power to take care of the swimming pool. The features are impressive and cornered impressively to catch our pain areas. 

. Pool Scanner

  • Bluetooth Connectivity 

It features Bluetooth connectivity and remote control that let you operate the device easily from a distance. The Bluetooth connectivity troubles you at the start, but it works efficiently once connected.

A gyroscopic navigation system lets your robotic pool cleaner move in the right direction. The quick scanner and navigation system create a robust combination of technology that lets you target even the toughest corner of the pool easily. 

  • Scheduling Function 

This also features an advanced control system and weekly scheduler so you can easily set your cleaner at automatic modes, such as 2x per week. The scheduling function works wonderfully when you want minimum manual efforts. 


The way Dolphin Sigma pool cleaners dive deep into the pool is spectacular. A built-in gyroscope navigation system and tracking type mobility ensure that the robotic cleaner is moving in the right direction. 

But if you combine the immense power of tracking with a jet on the top of the cleaner, it will automatically propel the pool’s water to detect the position and change its momentum. 

This compact robot pool cleaner easily scales up on the roughest surface and provides smooth tracking even on the challenging pool lining.
