Why Listen To Me About The Best Robotic Pool Cleaners?

My name is Wendy Owens and I have been around privately owned pools all of my life. My parents owned an in-ground pool, and my husband and I have owned both, above ground and in-ground pools.

We have been using robotic pool cleaners since we took over our pool cleaning chores in the mid to late 90’s, trying to save some time in our pool cleaning chores.

Let me tell you, they have really changed over the years. Getting better and more economical for everyone

Dolphin Sigma Robotic Pool Cleaner

(Best Value:)
Dolphin Sigma Robotic Pool Cleaner

The Dolphin Sigma is one of the latest models of Dolphin’s robotic pool cleaner line. It’s made with the latest technology and premium features that allow it to push over the limits.

The easy-to-use little robot features an anti-tangling swivel cable that allows Sigma to move around big residential pools covering up to 50 feet freely and easily. Its efficiency is backed up by three-year quality assurance.

Sigma eliminates the mess that comes with cleaning a dirty pool. It’s built on efficiency and doesn’t have bags to clean. Instead, it uses sizable top-loading cartridge-filters that effectively collect ultra-fine debris and fine dirt, resulting in optimal cleaning.

Its dual high-capacity filters allow Sigma to easily maintain higher suction and flow rates through every cleaning cycle.

Its scrubbing brushes are powered by triple-high output motors. The combination of dual brushes and a high output featuring the Triple 24V DC motors deliver one of the highest flow rates of a pool robot.

The powerfulness and duality of the brushes make it possible for the cleaner to fully attack tough contaminants, removing tough algae and bacteria from the pool.

In just 2.5 hours, you can deep clean your pool and remove all the dirty contaminants while using this robot. But this doesn’t mean that the robot consumes lots of energy since it runs on almost 90% less energy than standard pool cleaners.

Dolphin did extensive research before crafting this efficient pool cleaner with smart features. The machine has smart navigation with a gyro. This functionality is promoted by the next generation of Smart Navigation Software which delivers a well-optimized coverage and scanning of the pool, resulting in a whole new level of cleanliness. The robot can clean off your pool’s waterline/tile, wall, and floor with the advanced algorithm.

It’s difficult for an ordinary pool cleaning robot to resolve its tilt or orientation. However, Sigma has a 3-axis gyroscope onboard that monitors its angular velocity through 3 rotational axes, i.e., the yaw, roll, and pitch, resulting in optimal cleaning performance.

Sigma users have better cleaning control thanks to the smart features. The smart control system features weekly timers that automatically work to ensure that your pool is constantly cleaned at the desired interval.

What We Love About This Robot:

  • Dual brushes and triple motor power
  • Dual high-capacity filters
  • Gyroscope mobility system

Factors to Consider When Choosing a Robotic Pool Cleaner

Factors of considering a Robotic Pool Cleaner

A robotic cleaner is the best machine that you can use to keep your pool consistently clean. These devices get the job done effectively and easily. However, there is a wide range of robotic pool cleaner models on the market, making the purchasing process seem daunting.

To help you choose the right machine with great features, here is an overview of the factors to consider.

Micron Value

The debris and dirt size in pool cleaners are usually measured in microns, i.e., the smallest items that the machine can successfully filter from the water. Choose a device with a significantly low micron value since this will allow you to clean and disinfect your pool effectively. Don’t fall for generic terms such as mesh or fine since such machines aren’t as effective as those with low-micron filters.

Suction Power

A pool cleaner’s suction power is normally measured in gallons per minute (GPM). The best robotic pool cleaners have at least 70 GPM. It should be noted that the higher the number of GPM, the more powerful the machine is.

Pool Surface and Size

What type of surface does your pool have? The best thing about robotic pool cleaners is that they are versatile and can handle any surface. However, if your pool has fiberglass or slick tile, consider a machine with a soft and super-grip PVA cleaning brush.

The pool size matters because each robotic device normally has a fixed cable length. The machine needs to have the correct cable length to reach the pool’s farthest area from the power supply system. Don’t forget that the power supply must be several feet from the pool’s edge.


Choose a high-quality robotic pool cleaner model built with durable materials. This way, you are guaranteed lasting service delivery because quality parts offer value with lasting longevity.

What You Want to Clean

Some of these products are designed to vacuum the pool’s floor. On the other hand, others effectively clean pool floors, lower walls, and coves. Alternatively, some can do all these things and still clean the walls and water lines.

It’s worth noting that the latest models are highly effective at scrubbing. There is a broad range of cleaning options, but the best machine should be one that does the most while consuming minimal power. Don’t forget that the more efficient features a robotic pool cleaner has, the more expensive it will be. But the goal should be to get equipment that offers value for money.


A robotic pool cleaner that offers value for money will come with a warranty. This is important in ensuring that the manufacturer covers you if the device needs a repair or the unit needs a replacement.

5 Best Robotic Pool Cleaners FAQs


Q: What is a Robotic Pool Cleaner?

A: it’s a machine that uses an onboard filtration and power supply to clean the pool. A robotic pool cleaner needs very little user intervention during the cleaning cycle. Such a device can be connected to a power supply via a long cord outside the pool. However, some robotic cleaners are cordless.

Q: How Does it Work?

A: Once the cleaner has been connected to a power supply, it should be placed in the pool. It will then travel along the pool’s walls and floor, collecting dirt or debris in its bag, filter tray, or onboard canister.

Q: Are Robotic Pool Cleaners Expensive?

A: These cleaning devices aren’t cheap, and you should expect to pay a good amount of money for the premium features. They cost between $500 and $1200 on average. However, you can still find good pool cleaning equipment for $300, only that it won’t have lots of premium features and may have a limited cleaning capacity.

To determine if your robotic pool cleaner offers value for money, look for features such as its cleaning capacity and smart connectivity, including a mobile app and Wi-Fi or Bluetooth.
