Pool robots test 2021 • The 9 best pool robots in comparison

What is a pool cleaning robot and how does it work?

At aPool robots is an automatic cleaning device that is used independently for cleaning pool floors and, if necessary, pool walls. Through this the mechanical cleaning replaced by hand.

The functionality is similar to that of a conventional cylinder vacuum cleaner for the household. By creating a vacuum, the pool cleaning robot sucks up dirt where it drives along. Cleaning rollers remove the dirt beforehand. The sucked up dirt is collected in an integrated or external filter. The exact functionality depends on which type of pool cleaning robot you choose. A distinction is made between half- and fully automatic Pool robot models, as they can be found in the test comparison and the comparison table.

Areas of application - pool robots in use

In order to keep a pool clean, the use of chemical agents is essential, but not sufficient. Chemical residues, dirt, pebbles and other particles settle on the bottom and walls of a pool. These are not completely resolved with the normal pool filter system. This is where the use of a pool cleaning robot, like the one in theTest comparison is listed.

Accordingly, the area of ​​application of a pool robot refers to swimming pools. The prerequisite is smooth and firm surfaces, because the pool robot can only move unhindered and make its lanes on level surfaces.

What types of pool robots are there?


In the case of a semi-automatic pool robot from the test comparison, this is connected to the skimmer or the existing floor vacuum connection using a suction hose. The pump system must be switched on, which creates the suction effect. If dirt gets through the floor nozzles of thePool cleaning robot model sucked in, this is passed on through the suction hose into the filter system. There it is filtered out of the water and the purified water is fed back into the pool.

Floor and wall pool robots

Another variation on the Floor cleaning agents A fully automatic pool robot, which can also move down and clean the walls, offers classics. In some cases, the test shows that the device has to be repositioned because the independent transition from the ground level to the horizontal level is not possible. This type of pool cleaning robot sticks to the wall due to suction. The suction is so powerful that it doesn't fall off, but it does in his Locomotion is not restricted.


  • 2-in-1 device

  • Depending on the pool size and Battery capacity multiple charges for a complete cleaning possible
  • The nozzles attached to the pool walls can act as an insurmountable obstacle

Brain pool cleaning robot

Under Brain is an electronic “brain” in the form of sensors and Memory effect To understand technology that is built into a pool cleaning robot or not built into it (no-brain). These pool cleaning robots have been examined more closely in the test comparison because they promise intelligent pool cleaning. During the first use, they walk through the pool areas, “memorize” orientation points as well as obstacles, route lengths and shapes.

From this information, they create a cleaning plan in which they cover all areas as well as possible without having to make too many crossings or trips back and forth. In this way, complete pool cleaning should be effective and time-saving. In contrast, a no-brain pool robot pulls out of the Test comparison randomly at random its orbits.

This is how pool robots are tested

More experienced in external testsTest experts pool robots are examined in detail. According to their statements, the focus is on the aptitude test in various areas and priorities, which mainly focus on product quality, handling, task completion and Price-performance ratio Respectively. In addition to the test criteria mentioned, customer ratings are analyzed for the test comparison of pool robot models. These have a special influence on the product test, as each test product is evaluated by customers' personal experiences. This is followed by the analysis the test results match the manufacturer's information and practical test experience.

The Test results External test experts and customers are compared with each other in a kind of comparison test. This results in the weaknesses and strengths, which are combined into a test grade within the framework of a point system. TheTest comparison list arises, whereby this the test winner heads the list as the comparison winner. In this way, you will receive realistic information that will protect you from bad purchases and make it easy to find the right pool cleaning robot for you.


Size suitability

As a rule, many pool robots differ in the possible area that they can clean in one process. As external test results show, this mainly affects cordless pool robots. But also with Brain pool robot models it was noticeable in the test comparison that the Memory capacity is limited. Accordingly, the point of criticism of the maximum cleaning area based on your pool size should be taken into account when purchasing.

Battery life in connection with operating speed

Short battery life mean fast Emptying and charging. If the operating speed is so slow that a pool cleaning robot cannot clean the pool in one go, in the worst case scenario you will never find a completely cleaned pool because too many battery charges are required and take up your time.

In combination with the suitability of the size described above, this point of criticism can quickly lead to customer dissatisfaction. Battery life can be rated as the best results from 90 minutes.

Battery charging time

Forgot to charge the battery, but the pool urgently needs cleaning? Good if you own a pool robot from the test comparison with a short charging time. Batteries with a charging time of 12 or more hours usually no longer allow use on the same day. The best charge values ​​are around four to six hours.

Suction power

The one advertised by the manufacturer as the bestPool robots is of little use if the suction power is insufficient to suck up the dirt. Pool robots connected to skimmers act with the filter pump strength. Integrated filter systems should be able to hold at least 3000 liters per hour in order to achieve an acceptable suction power.

Setting options

Clever pool owners let their pool robots out of theTest comparison run daily. In most cases, the amount of dirt is then less. Setting options to, for example, eco mode for light soiling save electricity, conserve the battery, increase the service life and accelerate the cleaning process.

Floor and wall adhesion

If the swimming pool robot is in use, jumping into the cold water can quickly interrupt the cleaning process if the device is not resting firmly on the floor or on the pool wall. In addition to the suction power, the weight is particularly important. Heavy weight floor and wall cleaners tend to be Water movements easy to fall off the wall. Light devices react on the ground by “swimming away”.

Pure floor cleaning devices can therefore be heavier. They achieve the best results from a weight of around ten to twelve kilograms. Swimming pool robots for wall cleaning should have a maximum of nine kilograms.

Cable and suction hose length

Often there are separate generator sets between the socket and the robot scope of delivery contain. Depending on the size of the pool and / or the distance to the next socket, the appropriate cable length must be ensured. The same applies to the length of the suction hose. If this is too short, the robot may not be able to reach the other end of the pool.

Stops at obstacles

If a cleaning robot encounters an obstacle, theTest comparison found that some models get stuck on it and no longer continue their journey.

It is important to ensure that special obstacle sensors are available and that they work properly. They ensure that when it hits an obstacle, the robot automatically resets and continues in a different direction. Customer reviews provide information on how well this works with individual pool robots.

Unsatisfactory cleaning performance

Some models showed in the test that above all algae particles and heavier dirt elements were not sucked up. In most cases this is due to a low suction power and / or unsuitable brush rollers. With high-quality brush systems, a low suction force can be largely compensated for.

Shorter battery life

Manufacturers want to sell their devices, which sometimes leads them to Battery life to cheat. In some cases the actual battery performance is reduced by settings.How this behaves with your dream pool cleaning robot can be found in the customer reviews or in a test comparison.

Throwing up dirt

In order to be able to vacuum, the dirt must be able to be run over by pool robots. Are dirt particles from robot whirled up, they remain in the pool. Often this is due to leaky device elements, so that air is escaping from the sides. Sometimes an incorrectly installed cleaning roller can also be responsible for this. The test comparison shows whether and where the problem is with which model.

Entangled in the power cord

Usually the turns with a change of direction Swimming pool robots a cable joint on the housing. In addition, well-functioning obstacle sensors detect a cable just in front of, behind and above the device.

This is to prevent entanglement in the cable. It doesn't always work. The test comparison provides information on how this possible point of criticism behaves with the individual models and the test winner.

Difficult filter access

After each cleaning process, the robot the filter should be cleaned for the best cleaning efficiency. The test comparison shows models in which filter access proves to be difficult and especially long fingernails are a problem. The product test and customer ratings clarify which device models can be expected.

Despite Brain, haphazard routes

If you want to save electricity and time, choose one Brain robot. Customers often criticize that sooner or later their pool robot cleans in an uncontrolled zigzag and random manner. Full cleaning takes correspondingly longer. Annoying because brain devices are usually more expensive to buy than no-brain robots. You can find out in the test comparison whether your dream robot for pool cleaning is affected.

Worth knowing & advice

The evolution of pool robots over time

In the later middle of the 19th century, the first manual pool floor cleaners were used. They looked like a floor wiper. Dirt could be picked up by means of a suction hose and connection to the skimmer.

The first pool robot was introduced to the market in the 80s. Its suction left a lot to be desired, which is why the demand was limited. At the turn of the millennium, the "project" was again from Manufacturers added and the suction power improved. At the time, this was still not comparable with today's pool robots, but they delivered significantly better cleaning results than the conventional cleaning products currently on offer. Today, pool cleaning devices do their job effectively so that manual labor is no longer required.

Numbers, data, facts about pool cleaning robots

Every year, thousands of pool robots are implemented in Germany alone. With increasing demands for comfort, more and more pool owners are opting for automatic pool cleaning. Experts anticipate a further high increase in sales figures, which is not least due to the fact that more and more garden owners are choosing a pool.
