We all know choosing the right robotic pool cleaner can be a daunting decision. Normally priced on the higher end, you want to make sure your’e getting great value for money. So we’ve decided to take a look at two premium robotic pool cleaners The Dolphin Sigma and the Dolphin Premier to see how they match up when it comes to features and performance.
Dolphin Sigma Robotic Pool Cleaner quick review
The Dolphin Sigma robotic pool cleaner is a highly advanced robotic pool cleaner that features state of the art pool cleaning technology.
It is the first pool cleaner to have not one, not two but three highly efficient, commercial grade DC motors reducing energy use of up to 90% while producing the most powerful suction and navigation in a robot.
Designed to clean all pool surfaces including tile and even right to the waterline with pinpoint accuracy. Using powerful dual scrubbing brushes, the Dolphin Sigma can perform a deep clean removing algae blooms, scale build-up and even corrosion while its HyperGripTM continuous Tracks allow for maximum traction when menauvering over drains and even climbing vertical walls.
- Highly energy efficient
- Excellent traction
- Large top loaded filtration system
- Limited 3 year warranty
- Built-in weekly timer
- Does not come with a caddy

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.
Dolphin Premier Robotic Pool Cleaner quick review
The Dolphin Premier by Maytronics is an advance robotic pool cleaner designed to take automatic pool maintenance to the next level with its easy plug and go operation. The Premier features MultiMedia debris bags giving you the option either using the micro-filter for micro particles, or go the oversized filter for leaves and the large debris.
Using it’s patented CleverClean technology it maps out the most efficient path in which to clean giving you more time to enjoy your crystal clear pool. It uses a 60ft cable with anti-tangle technology to ensure complete pool coverage while being highly reliable when it comes to not becoming tangled.
The Premier Features dual scrubbing brushes that forcefully attack tough dirt and debris, while its HyperGrip tracks allow for maximum traction when it comes to the cleaning of pool walls and waterline.
- Easy to clean filters
- Powerful cleaning
- Easy installation
- Cleans waterline
- Doesn’t come with caddy
Dolphin Premier Specifications
- Manufacturer: Maytronics
- Brand: Dolphin
- Model: Premier
- Pool type: In ground
- Dimensions: 23.5 x 20 x 14 inches
- Weight: 22lbs.
Now lets take a more in depth look at the Dolphin Premier robotic pool cleaners features and their benefits.
Dolphin premier robotic pool cleaner features
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.
