This drives the wall lengths, width of the steps, size and shape of the pool right precisely.

It also enables the cleaner to not move around the same completed path and utilize less energy. Added lead being the first cleaning robotic gyroscopic navigation system provided with gyroscope sensors, they have the exact location being tracked endlessly.

Programmable timer

Cleaning cycle / Time

The standard time taken to clean the complete walls, waterline and floor with every corner being covered is 2.5 hours irrespective of the dirt accumulated. 

The advanced navigation system inscribed lets the process faster as the mapping technology ensures the minimal distance to be traversed within appropriate time.


This stunning robotic cleaner has got its hands with dual active scrubbing split brushes, making it more convenient to clean the walls and floor and eliminate the marks and dirt signs. 

Having high RPM for moving the brushes than other pool cleaners it instantly remove the long fixated dirt as well.

The split in the dual brushes gives the comfort of 4 whisks both in the front and rear end. HyperBrush spinning with double speed ensures with no cloudy water and algae bloom around.

Filters and Filter cartridges

Dolphin Sigma Robotic Pool Cleaner is embedded with two variant filters and two oversized large cartridges. 

One filter in is meant to collect the smaller particles such as dust, algae and sand within whereas the second is to collect the larger particles like leaves, rocks and wrapper materials.

The collected waste is then accumulated into the extra- large filter cartridges leaving enough space for the whole pool cleaning without any check.

Surface, Walls and Stairs cleaning

Since the stored water are tend to be slippery, the dolphin sigma are designed with independent rubber tracks instead of the wheels which accommodates the mobility on the surfaces. 

The Hypergrip tracks system enables them to stand still on the vertical walls which provides the complete scrub to the surrounding walls.

With gyroscope Mobility system, the robot can tilt orientation with angular velocity and manages the uneven and flat stair surfaces without any distortions.

Not – so – heavy with such astounding features, this robotic pool cleaner is 35 pounds (16 kgs) in weight. 

Though its heavy compared to other sigma pool cleaners, its triple high suction motors and extra- large carriage baskets explains the need.

Its fixated structure enables the strong movement on the rough and tilted surfaces for the efficient mobility and work to be done.

Conclusion - Dolphin Sigma Review

Nonetheless, the high price, its demand for the purpose is huge with all the advanced features standing upright with the technologies.

Right from the navigation with gyroscopic intrusion to smart controls via Bluetooth and Wi- Fi. With amazing suction rate 75 gallons per minute, its long flawless cable is sure an attractive attribute.

Cleaning steps might seem a bit trouble, but tilt orientation sure covers the issue. Over all, the body is little heavy making the shift quite not easy but a super clean pool on such high rates is no easy way to go.
