Robotic Pool Cleaners: Which are the 3 Best to Buy in 2020

Getting To Know More About Robotic Pool Cleaners

If you are the owner of a swimming pool in your home, it is quite obvious that you would like to keep it clean and in good condition at all points in time. This is possible only if you have the right equipment and devices that can take care of the cleaning. While there are many ways by which swimming pool water can be cleaned, in this article, we will try and have a look at the growing importance of robotic pool cleaners. They were in use in its original form way back in the 1960s. A few companies such as Hayward, Zodiac, and Pentair are known to have manufactured different types of robotic pool cleaners.

In this article, we will have a closer look at the reasons for the growing popularity of these robotic pool cleaners. Additionally, we also will spend some time, having a look at three different brands and makes of the robotic pool cleaner. We are sure it could come in very handy for choosing the best robotic pool cleaner. However, before going through such a review, we will have a look at how these pool cleaners work and what are the main advantages of the benefits of using them.

How Do These Cleaners Work

Let us try and understand the basics as far as the working of these robotic pool cleaners is concerned. A transformer is required and the same is plugged into the wall out and the transformer is powered with the help of a long cord of around 50 feet. The transformer takes around 110 volts of power from the power outlet. This is then transformed or it is stepped down to a much safer level of around 24 volts. The low voltage power operates the cleaner. This is done by activating DC brushless motors or two stepper motors. You also have a pump motor that draws water from the unit beneath it. The same is discharged at the top of the unit. Apart from vacuuming the pool, the pump motor also performs some other functions. It helps to keep the unit firmly pressed to the floor of the wall. The drive motor also performs the task of propelling the robot cleaner onto the pool surfaces. You have a grain train that is connected to power the tracks and belts. They also rotate two cylindrical rollers in a transverse position and when this happens the actual scrubbing and brushing of the pool surfaces take place.

You also have more advanced and elaborate robotic cleaners and these are controlled by computer chips. They use sensor bars or they also make use of infrared scanners. These are done to adjust the transition from floor to wall. There are also a few robots that are capable of climbing up the waterline and also scrub the tile. Many of the modern machines also come with radio remote controls that can help you to control the machine sitting in the lounge chair.

What Are The Advantages

Robotic pool cleaners are not attached to any pool circulation system. Hence, they cannot produce any resistance or back pressure as far as the pool filter system is concerned. The pool filter can remain nonoperational. In fact, many recommend that the pool cleaner should be operated with the pool filtration system is in a switched off position. This perhaps will allow better functioning of the machine. The suspended particles will be able to settle to the floor as and when the cleaner is operating.

One more advantage of having a robotic pool cleaner is that they come with a self-contained filter. This can be easily cleaned. Further, it also comes with an onboard filter cartridge or bag and it has the ability to filter down to almost 2 microns. Additionally, robotic pool cleaners also are a much better option when it comes to pool coverage and overall speed of operation. However, we need to understand that not all the units are capable of climbing the walls.

Disadvantages of Pool Cleaners

There are some disadvantages as far as these robotic pool cleaners are concerned. The cost is a prohibitive factor for many. It could cost much more than a pressure side or suction-based pool cleaners. They are also heavier in weight and bulkier in size. Repairs at times can be quite expensive. Further, their ability to handle heavy debris such as leaves, acorns, large sticks, and other such things are still not very well known.

Now that we have some basic information about robotic pool cleaners, let us straight get into the task of reviewing three different makes and models of these special types of cleaners. It will help readers to have better information and more knowledge about the various things to be kept in mind when it comes to choosing these types of cleaners.
