What is a Robotic Pool Cleaner?

Surprisingly, robotic pool cleaners have actually existed since the early 1960s. These units are known as “robotic” since they contain motors, sensors, and chips.

However, it’s only relatively recently they have been becoming commercially viable and owning an automatic pool vacuum is more popular.

Here’s how they work. A transformer is plugged into the wall outlet, and a cord from the robotic cleaner plugs into the outlet of the transformer for safety. The cleaners, vacuum the pool, and the drive motor, moves the robot cleaner across the pool’s underwater surfaces. Some units can also climb up the sides of the pool to the water line and scrub the pool’s tiles.

The best robotic cleaners usually have computer chips or sensor bars that automatically adjust to the contours of the pool’s floor or walls.  If you want the convenience, you can use robotic cleaners with remote control, this will allow you to sit in comfort to steer the machine.

When selecting a robotic pool cleaner, you need to choose between an above-ground or in-ground cleaner as they are quite different. Above-ground pools are cheaper and more portable, but they’re also less durable and stable than underground pools.

So in this day and age where robots are making life easier all around the house, why not let them look after your pool too!

Robot pool cleaner buyers guide

If you’re looking for the best robotic pool cleaner here are some of the key features to take up:

Pool Cleaner Connectivity

Today the Internet of Things (IoT) has been a game-changer in terms of home appliances. Some pool cleaners offer connectivity through remote control or smartphones/tablets. This provides more flexibility since you can operate the robot from a convenient place such as a beach chair.

Model Speed

You should also consider how long a robot will take to clean your pool. Factors to consider are the total size and number of coves, steps, and ladders. Robots typically take about 2-3 hours to clean a pool and 1 hour for a “quick clean.”

An X-factor to consider is the quality of the cleaning. Make sure to pick a robot that can clean the pool not only quickly and efficiently but also thoroughly. A machine that spends half its time spinning in circles isn’t really useful.

Robot Motor

Make sure to consider various factors related to the motors. How many are there? What kind are they? How much power do they produce?

These are all big questions to take up when picking a new robotic cleaner. In general, you’ll want the motor to be powerful enough yet not a power hog.

Besides mains power cleaners there are solar-powered robotic pool cleaner to consider. These get 100% of their power from sunlight, so are not only an eco-friendly option but can also reduce your electric bills.


Scrubbing the pool’s floor typically won’t be a problem for robotic pool cleaners. The walls are a different story. Make sure to pick a unit that’s able to climb the walls effectively and give them a good scrub.

In fact, some units can even climb and scrub all the way up to the water line. Not all units are able to do this and if your cleaner does not do this then you will need to do it by hand or some other means making these cleaners not very practical.

Cleaner Tracks or Wheels

These are the main ways the programmed machines move around inside the pool. Which one should you look for? Both options can include complex systems like 4-wheel drive.

What’s most important is whether the tracks or wheels provide an effective grip to the pool’s floor or walls. If they can do that, then it will improve the unit’s overall cleaning ability. For example, if the robot can move in reverse or turn on a dime, it will make cleaning more efficient.

Also, be sure to check if the robots drive system is compatible with your type of pool. While most robotic pool cleaners are safe to use on vinyl pools or more delicate surfaces, it is good to confirm before you pull the trigger on your purchase.  

Pool Navigation

Automatic pool cleaners have a built-in computer that tries to “learn” the pool’s layout. It then uses algorithms to determine the most efficient path to clean the pool. It also has to watch out for obstacles like ladders and steps.

This highlights the importance of picking a unit with quality navigation. This will make the pool’s cleaning faster, which is definitely a plus. If the cleaner does not have a good navigation system the robot could have problems like running into objects and even going in circles.


Some of the top brands include Dolphin, AquaBot, and Polaris. These are all established companies, so they’re a good option if you’re looking for solid quality and good customer support.

Like other types of products watch out for robot pool cleaners from generic and off brands. This will likely cause issues related to durability, functionality, warranties, etc.and they usually have a poor customer service if any.

Pool Cleaner Filter Size

You should always make sure to pick a robot cleaner with an easy-to-clean filter. This will make the process faster and easier and thus reduce down-time when you’re cleaning the pool.

The filter size is another key issue and matters. What should you look for? Pick a model with a filter that’s large enough to clean your entire pool without you having to clean the filter. This will make the cleaning session more efficient.

This is an issue that is just as important as the unit’s motor or connectivity, but if you have to keep cleaning the filter, it can make cleaning the pool very tedious and frustrating.


What’s the “average” price of units like the best above ground pool robotic cleaner? If you’re looking for a residential unit, you should expect to pay about $400 to $1,300. Yes, high-end units will have bells and whistles. However, you can find solid units at both extremes of the price range.

Robotic cleaners are generally more expensive than other types. That’s due to factors like their ease of use and performance. However, the higher price tag might be worthwhile if it means cleaning will be faster and easier.

The top brands like Dolphin offer a wide range of different models at different price points. Make sure to consider your particular wants and needs to pick the right unit at the right price.


The warranties for robotic pool cleaners tend to range from 1 to 3 years with high-end units offering longer warranties. These are sometimes comprehensive warranties that cover “everything.”

However, in most cases, they’re limited warranties that only cover things like defects due to materials, manufacturing, or shipping. Always read the warranty terms & conditions, so it’s clear what it does and doesn’t cover.

Vacuum Pressure

This typically won’t be an issue if the robot is floating and starting its work. However, if the filter bag gets full, that’s often when the vacuum loses pressure. So, look for a unit that maintains its pressure, whether the filter bag is full or empty.

Clean swimming pool

The pros and cons of a robotic pool cleaner


Circulates Water

Pool cleaning robots continuously take in and expel water, which helps to circulate the pool’s water. This is critical to balance the pool’s chemicals. It boosts the overall safety of the pool water and also provides more accurate readings when you check the pH balance, for example.

Removes big and small particles

You can use the same unit to handle this goal while it could require several different machines or tools when you do it manually. Both big debris (e.g., acorns and leaves) and small debris (e.g., dirt and algae) should be regularly removed from your pool to keep it as clean and safe as possible.

Easy to Install, Use and maintain

These are all key factors when operating any type of pool equipment like robotic cleaners. The overall ease of use will be based on the model itself. However, robotic cleaners are generally easy to install, use and maintain.

Keep in mind the initial costs will be high since the cleaners cost hundreds of dollars. While maintenance tends to be easy repairs can be quite pricey due to the mechanics and electronics built into the models.

Cleaning Convenience

If you have lots of time and energy, then you should probably consider manually scrubbing your swimming pool. However, the task can be quite time-consuming and tiring.

This is one of the main benefits of a robotic pool cleaner. You can even sit on a lounge chair and enjoy your favorite cold beverage while operating the robot via remote control.

Filters Water

A swimming pool already has a filter, but it often works overtime to keep the pool water as clean as possible. Different conditions can influence how hard your filter has to work such as the number of people in the pool, mount of debris it collects and the climatic conditions and so on.

A robotic cleaner can be very effective in filtering out unwanted debris and chemicals from your pool. This, in turn, will help to keep the water cleaner and healthier which is better for your health and enjoyment.

Scrubs Pool’s Tile Lines/Walls

The best robotic pool cleaners can “learn” and remember the pool’s shape. The units then use their brushes to scrub the tiles and walls, so they’re super-clean. You can even find high-end robots that clean pool ladders, which are tougher due to their shapes.


Built-in Filter Cleaning

The good news is some filters are quite easy to clean and will just require you to remove them, then use a standard hose to clean the filter. Research this particular issue when considering a particular unit.

The problem is the small size of the robotic pool cleaner vs. a swimming pool filter. This means you might have to clean the filter either after every use or even while you’re operating the unit.

Cleaning Effectiveness

The effectiveness of robotic cleaners differs from model to model. Some units are very efficient at cleaning your entire pool, so it’s sparkling clean. Others might run for several hours and just tidy up a small section of your pool.

This is based on several factors, but is mostly related to the robot’s quality. A high-end unit will have the latest and greatest tech and features, but will also have a sky-high price tag, so it’s an issue to consider.

High Price Tag

The price of robotic pool cleaners differs based on various factors like the brand, power, tech, features, and quality. That said, you should be prepared for a steep price and repairs.

This is due to the complex tech and mechanics of today’s robotic cleaners. If you require your cleaning machine to connect to a remote control or mobile device you should expect to shell out more money.

Cord Length Limits

Robotic pool cleaners are limited based on the length of their power cords. The actual length of will affect how much area it covers.

Another key factor is the power outlet location. This will affect how much cord you’ll need just to get to the pool itself. So, it’s important to consider this issue when determining which model to pick

The robot’s operation is also quite easy. Make sure to read instructions so you’ll know how to operate it properly. Routine maintenance includes cleaning the filter. This often just involves removing it from the machine, then using a standard hose to clean it out.

How does a robotic pool cleaner work?

A swimming pool is always equipped with a pump and filter system that circulates pool water and cleans it and lets the cleaned water back into the pool.

The goal of robotic pool cleaners is to scrub the pool’s walls and floor and get rid of any dirt or debris that does not float and get sucked through the main filter system. Robotic cleaners scrub the floor and walls and some of today’s units not only scrub the pool, but also filter water at the same time.

An indirect benefit of the robots is they reduce the workload and cost of the pool’s pump and filtration system. As a result, you can enjoy a cleaner pool and save money. The operating costs of the robotic cleaners are quite low with solar-powered units costing absolutely nothing to operate.

Are robotic pool cleaners any good?

If you’ve read pool robot reviews, you might be wondering this question if you’ve encountered some bad reviews. So, what’s the bottom line?

In general, these units are just as effective as manual pool cleaners. The main benefit is the process is done automatically by using the using the unit’s built-in programs or allowing it to “learn” your pool’s size and shape.

However, the degree of a robot cleaner’s effectiveness is based on various factors. Some units tend to be quite reliable while others might run around your pool for several hours and only clean a small area or worse—just move around the debris.

So, it’s important to shop around for a quality unit. If a particular robot cleaner model has received mostly negative reviews, it’s a red flag, and you should probably shop around.

Are robotic pool cleaners safe?

This is a big question when you consider units like the best inground robotic pool cleaner. As with other electric equipment, it’s important to take certain steps to make sure the operation is as safe as possible. Here are some helpful tips to get you started:

1. Remove pool tools

Before you start using the automatic pool cleaner, it’s critical to remove all pool tools since they can get stuck in the machine’s wheels and cause it to stop or move in circles. This will reduce the unit’s efficiency.

2. Check backup valve

You should do this if your machine keeps getting stuck in the pool’s corners. Replace the valve if it isn’t working correctly, so you get maximum performance.

3. Check head float

If this unit is cracked, then it will fill up with water. Make sure to check the float by first detaching it then, shaking it. If you hear or feel the water, then you should replace the head float immediately to improve the unit’s operation.

4. Check suction

This will help to make sure debris won’t get left behind. Just put your hand a little below the water’s surface under the machine. If the suction is weak, it is most likely that the airway is clogged, or the cleaner bag is full.

5. Check full bags

This is important because if it’s full, the cleaner will leave behind debris and also won’t function effectively. Check the bag before you start cleaning your pool, then check it periodically.

6. Check wheel gears

If the robotic cleaner goes in circles, it will likely be related to 1+ of the wheels not working properly. So, check the wheel gears to verify they’re not worn out. If they are, you should replace them immediately.

What robotic pool cleaner should I buy?

If you’re looking for the best automatic pool cleaner, it really depends on various factors. Which features do you want the unit to have? How much are you willing to spend? Has a particular unit received mostly positive or negative reviews?

As with other products, the term “best” is relative. However, by first considering your wants and needs it will be easier to select the unit that’s right for you.

What kind of maintenance is needed for a robotic pool cleaner?

Even if you pick the best inground pool cleaner, you’ll have to do some routine maintenance for the unit. One of the main ones is cleaning the filter. This highlights the need to pick an easy-clean filter that can be easily removed and washed using a hose.

There are also routine checks you should do on the unit. They include the:

  • Bag
  • Suction
  • Wheel Gears
  • Head Float
  • Backup Valve

These items are relatively easy to replace, so it’s a matter of researching how to do that. On the other hand, other mechanical and electronic repairs will likely require hiring a technician. Due to the complex design of today’s units, you might have to deal with high costs for these repairs.

How long do robotic pool cleaners last?

It depends on various factors like the unit’s overall quality and how well you maintain it. In general, you should expect the unit to last 3-5 years and as long as 8 years. An added bonus is you’ll likely need to replace few parts.

If you want to make a big investment in your pool, then consider a robotic cleaner that’s covered by a warranty. They usually range from 1-3 years but is arguably worthwhile in terms of protecting your investment.
