Robotic Pool Cleaners Buyer’s Guide    

Type and Size of Pool

Choosing the best robotic pool cleaner highly depends on the size and the type of your pool. A device designed for small pools will not perform well in large swimming pools. Also, a larger cleaner is not suitable for small or above ground pools. Make sure you buy a cleaner suitable for your pool size.

It is also important to buy a cleaner that performs well on different materials like gunite, tile, or vinyl. Corners and steps also require cleaning, so the best robotic pool cleaner must be able to clear these too.

Climbing Ability 

The best robotic pool cleaners including the Aquabot Breeze 4WD cleaner are capable of climbing your pool walls and stairs and clean them thoroughly. Black and yellow algae [1] tend to form on the pool walls and give the pool a dirty aspect.

A good in-ground pool cleaner like Aquabot Breeze XLS we reviewed should be able to clean both the pool floor and walls. Most of the robotic pool cleaners can climb on walls and scrub at the waterline. However, some models get stuck at the stairs. Make sure you check the devices’ specs before making a decision.

Pool Debris  

Depending on the area where your pool is placed, the dirt and debris you need to remove differs. A swimming pool placed in your backyard is like a magnet for leaves, twigs, insects, or finer debris like pollen.

A good robotic pool cleaner should be able to remove all these and return crystal clear water. Before deciding on a specific model, check whether it can clean the dirt and debris you usually have in your pool. For small particles of dust or pollen, your cleaner should have ultra-fine filters. 

There is no point in spending money on an expensive in-ground pool cleaner if you still need to gather the leaves with a classic net.


Properly maintaining your robotic pool cleaner especially topnotch Aquabot pool cleaner is mandatory if you want to have it for a long time. Although many manufacturers advertise low maintenance requirements, your cleaner still needs minimum attention.

Remember to take it off the pool after you used it and clean it with water. The pool’s chemicals and salted water are harming the device. Also, it is very important to clean the filters and empty the filter bag.

To conclude, even the best robotic pool cleaner requires minimum maintenance. The key is to find one that does not need too much attention.

Filter Cleaning 

The filter box is the most important part of a robotic pool cleaner. All particles of dirt and debris are retained by the filter while clean water is sent back into your in-ground pool.

Filters should be checked weekly and changed when worn. However, you will be able to use them for a time before replacement is needed.

In case you own a large pool, you must choose a cleaner that features dual filter bags so you would be able to run the device for longer between changes.

Cables and Cords  

Robotic pool cleaners require electricity to function. The simple idea of water and electricity might seem scary. However, these devices have security measures that prevent accidents.

When shopping for a robotic pool cleaner, you need to make sure that the power cord length allows the device to clean the whole pool.

Buying a device with a 30 feet cable to clean your 50 feet pool does not make any sense.  A larger cable will cause your robotic cleaner to tangle despite the existence of an anti tangle swivel cable.

Always pick a cleaner suited for your pool size, with the proper cable length.

Extra Features  

Lately, many robotic pool cleaners come with smart functionality. You can link the cleaner to your smartphone or remote control and manage it via this device.  

Other very useful extra features are the smart sensors that find the best cleaning path and shut down the cleaner after finishing the cleaning cycle. It is far more comfortable for the cleaner to find the waterline and the walls.

One of the best features of the robotic pool cleaners is the programmable timer. You can schedule the swimming pool cleaner to clean pools every day or every other day. This way, you keep your pool ready for a swim. 

It's worth checking if the robotic pool cleaner you have in mind has all these smart features. And if they work as advertised.


If you consider buying a robotic pool cleaner, our team recommends you to avoid really cheap devices as these might prove to be a waste of money. As a rule of thumb, a robotic pool cleaner with the same price tag as an old-fashioned automatic pool cleaner will surely disappoint you.

Another important aspect is the warranty. These devices often require replacement parts due to the long exposure to water. Having an extended warranty is always a good idea that will save you money.

Reasons for Buying a Robotic Pool Cleaner  

Apart from being cool to own a high-tech gadget, a robotic pool cleaner saves you a huge amount of time and money. These devices use less energy to run compared to a standard pool filtration system.

And since you will regularly use the robotic cleaner, you won’t have to change the pool filter too often. All the waste is picked up and contained by the cleaner.

Using the robotic cleaner helps you reduce the number of chemicals needed in your swimming pool, and this has many health benefits. 

Lastly, although it might seem expensive, a robotic cleaner will save you a lot of time and money especially when you know how to properly use a vacuum or the robotic cleaner —no more spending time under the scorching sun or risking back pain.
