Buying Guide for Robotic Pool Cleaner

Our list of the 7 best robotic pool cleaners may have given you some insights into what these machines are capable of and how they work. Now, if you want to improve your pool cleaning routine and make the best out of your investment we suggest you go through our buying guide and leverage our research and knowledge.

Pool type

Not all robotic pool cleaners are designed the same, so the first thing that you have to determine is the type of pool you own. Your pool’s size, shape, waterline, steps, stairs, and even what type of debris does your pool collects come into play.

For example, if the size of your pool is large and if you are going for a corded robotic pool cleaner then you should choose a cleaner that has a longer cord or even go for a powerful cordless cleaner. Investing in a short cord will limit the reach of the cleaner and you will have to constantly shift the power supply for cleaning the pool.


One of the most important factors that you should keep in mind when buying a robotic pool cleaner is the cord length. Why? Because choosing an appropriate cord length will not only allow you to reach every corner of the pool but will also eliminate the chances of twisting/tangling (in case of longer cord) and cord restriction (in case of shorter cord).

When buying a corded robotic pool cleaner, make sure the model comes with an anti-tangle swivel. Though most of the new generation models come with such features, this is something that you should consider to keep the efficiency of the cleaner high as twisted and tangled cords can hinder the cleaner’s performance.


Depending on where you live, your pool collects various debris like leaves, pollens, algae, dirt, and dust, which means your cleaner will also need to have different filters to suck the debris.

High-end pool cleaners are reinforced with large fitters that can be switched or changed to collect small-large debris from the pool. Large filters will collect larger debris like leaves and small filters are designed to collect smaller debris like pollen, and dirt. Other fine debris like dust and bacteria will require small pores filters that can come with the model or could be bought separately.

Almost all robotic pool cleaners come with a replaceable cassette or bag that collects the debris. It is important to clean or replace these containers before starting the next pool cleaning cycle because clogging could result in poor performance and eventually reduce the life span of the machine.

Tracks or Wheels 

Your pool cleaner moves inside the pool with the help of wheels or tracks. Wheel-driven robotic pool cleaner can come with two or four wheels attached.

Wheel variant is a suitable choice for people who want economical machines out of their investment. Wheeled pool cleaners do not depreciate faster and can navigate easily in the pool providing outstanding results.

Tracks variant pool cleaners have a very strong grip and traction in the pool. Plus, track-driven cleaners are more efficient in loosening dirt and debris in the walls and waterlines. The rotating scrubbers in the track robotic pool cleaners have more power that helps in deeper cleaning.


There are many models of robotic pool cleaners in the market and each one has its features for cleaning. Some cleaners are in-ground i.e. cleaning the pool’s floor. High-end robotic pool cleaners are created to clean both walls and floors efficiently.

When choosing a pool cleaner look for the feature that says In Ground Cleaning if you want a cleaner to deep clean your pool’s floor.

An Above Ground Cleaning feature of robotic pool cleaners means they are designed to skim the pool’s surface. Some brand mentions their products are capable to climb the walls, this means that particular model can brush off dirt, algae or other debris from the walls and waterline.

We suggest going for a model that can clean and cover most of the pool area, which includes floor, wall, waterline, and surface.


Robotic pool cleaners consume 82% less power in comparison to regular hydraulic pool cleaners however, the energy efficiency in some models can vary according to various factors.

The energy usage of robotic pool cleaners can vary from 180W to 1000W per hour depending on the unit’s size. When choosing an energy-efficient pool cleaner look for battery, power usage, and time it may take to clean every corner of the pool.


When it comes to investing in a valuable product like robotic pool cleaner, they must be built to last and have good warranty coverage.

To check whether the model is worth your investment, you can either look for customer reviews or feedback to assess common problems/faults or you can stick with a reputed brand to ensure you get a long-lasting pool cleaner.

Advanced Feature 

If you want your robotic pool cleaner to clean the pool with just the tap of your mobile screen, some models support such quick-access features and can be programmed, scheduled, and operated by smartphones.

Some models also come with advanced sensors and scanning features that can speed up the cleaning process without the machine getting stuck anywhere in the pool. You can find relevant features in our ‘Best feature’ sections.


Another important factor to consider before buying a robotic pool cleaner is to check whether the warranty coverage is for a year and more than that. Warranties may cover different units like motors, cable, suction pump, container, etc., contact the manufacturers to obtain more information.

Talking to them first hand can help you extend the warranty period too. If a warranty is your prior concern you can opt for models like Aquabot X4 Robotic Robotic Pool Cleaner and Paxcess Cordless Automatic Pool Cleaner that covers for 3 years and 2 years respectively.


Go back to the first factor that we discussed (pool type) to ensure you spend appropriately in your next robotic pool cleaner. If you have a large pool then spending on a larger unit is advisable because of three reasons – more power, bigger filter cassette and bag, and quicker cleaning.

Investing in a high-capacity pool cleaner will demand a higher price but, it is all worth it if you consider other factors as well.


Robotic pool cleaners are one of the best inventions we have come up with, they save us time, energy, and efforts. Why get down into the pool and scrub the walls and floors when you know there is a powerful alternative that can do the same more efficiently. And meanwhile, you can chill in the corner.

However, choosing the best robotic pool cleaner among the bests could be a daunting task and we get that. So, if you are still confused on what model to bring home you can rely on our top three picks:

  • Dolphin Nautilus Robotic Pool Cleaner – This pool cleaner is suitable for people who are looking for excellent cleaning performance that also has advanced intelligence. If you can compromise with the cable length or you have a small pool, it might be the best option for you.
  • Polaris F9550 Sport Robotic Pool Cleaner – If you are willing to invest in a machine that is fully loaded with advanced technologies, features, and can deliver unmatchable results, this is the perfect option. You will need to have a high budget though.
  • Aquabot X4 Robotic Robotic Pool Cleaner – For overall value at a decent price, this award-winning pool cleaner can come in handy if you can manage without a daily or weekly programmable system.
