Now lets take a more in depth look at The Dolphin Sigma robotic pool cleaners features and their benefits

Dolphin sigma key features

PowerClean™ Dual Scrubbing brushes

This robotic pool cleaner was designed with not one, not two but three powerful scrubbing brushes. The Dual spinning brushes brush the pools surface while a third brush in the middle rapidly oscillates back and forth to dislodge stubborn dirt or algae. PowerClean™ Dual scrubbing brushes are especially effective against biofilm a microorganisms that increases chlorine demand, destroys water quality. The Sigma even vacuums when in reverse for ultra efficiency.

Triple High RPM DC Motors

The Dolphin Sigma packs three onboard DC motors that can provide up to five time it’s rated torque without stalling.  The revolutionary 24 volt DC motors require 87% less energy than the AC motors that power old fashioned pool cleaners costing on average 5cents an hour to run saving money on your power bill with every clean.

Large top-loading cartridge filtration system

The Sigma features a massive top loaded cartridge, the highest capacity recorded in a robot to allow for maximum efficiency meaning your robot will spend less time being emptied and more time cleaning. These top loaded filters are also very simple to clean and remove when necessary. The Filtration rate of the Dolphin Sigma is  75 gallons per minute for remarkable water quality.

HyperGripTM Continuous Tracks

The Dolphin Sigma comes equiped with HyperGripTM continuous tracks that allow for maximum traction when cleaning over drains and over slippery pool surfaces like tile. The Hypergrip tracks also help significantly with maintaining constant traction when cleaning the pools walls allowing the Sigma to easily reach right to the pools waterline. In return all of this leads to less slipping, meaning less energy used resulting in your pool being cleaned more efficiently.

Now lets take a look at the Dolphin Premier.

The Dolphin Premier robotic pool cleaner uses its SmartNav™ technology to map out the most efficient path when cleaning your pool with unparalleled precision, This feature also gives it the ability to detect objects in its path like ladders and drains and navigate around them

Dual Layered Filtration

The Maytronics Premier packs MultiMedia™ filtration giving you the option to choose what sort of debris you want to tackle. If you want to clean fine debris that usually pass through most cleaners, then choose the micro filter. For larger debris like leave, acorns or sticks simply insert the oversized bag.

Anti-tangle swivel cabel

The 60ft Anti-Tangle Swivel Cable allows your Dolphin premier to move around the pool with ease while also not becoming tangled around it’s own chord. This cable swivel is one of the greatest engineering accomplishments in the automatic pool cleaner industry. The swivel ensures that your cable won’t get tangled or knotted, This feature makes the Premier one if the most reliable robotic pool cleaners when it comes to providing an un supervised clean.

In-built Weekly Timer

This feature takes automatic pool cleaning to the next level by allowing you to set scheduled days for the Premier to automatically clean for you. Set the timer to either every 24, 48 or 72 hours. This feature is great because it means your pool continues to get cleaned even when you’re not at home. It also has a full filter indicator that lets you know when the filter needs to be emptied.

Dolphin Sigma vs the dolphin premier summary

For us, the better robotic pool cleaner when taking price and performance into consideration is the Dolphin Sigma. Though these two robotic pool cleaners packed many of the same features there were a couple of extras we felt gave the Dolphin Sigma the edge.

We couldn’t go past the Sigmas highly energy efficient Triple High RPM DC Motors meaning less power was used with every clean which in return saving you money in the long run.

Another feature that really stood out that we couldn’t go past was the Sigma’s ability to tackle biofilm, a microorganism that has a bad reputation for increasing chlorine demand and destroying water quality which many pool cleaners struggle to get rid of. It is for these reasons we feel like the Dolphin Sigma is better value for money.
