Which one has better features?

iRobot and Cecotec currently have a share of over 80% in the robot vacuum market in Spain. Bearing this in mind, it is normal for consumers to wonder which brand is better. Let’s start from the basis that iRobot, with its Roomba robot vacuum cleaners, was the pioneer brand and that this gave it the possibility of taking a hegemonic position. In contrast, Cecotec, with the different versions of Conga, took longer to land on the market. However, he did it with great force and with a clear determination to compete.

That said, how do you determine which brand offers the best features and benefits? It seems difficult, but here we have analyzed the opinions of robot vacuum cleaners from hundreds of Cecotec and iRobot users and, in addition, we have made a comparison with the characteristics of their main models of basic, medium and low range. These are the conclusions we have reached:

The experience: iRobot has been manufacturing robot vacuum cleaners for more than 20 years, while Cecotec has only designed and produced these devices for just over 5 years.

Function scrub: This feature is not available on the iRobot robot vacuum cleaner but in many of Cecotec. In fact, it is possible to find it in mid-range models in its catalog. Of course, they are not capable of deep scrubbing.

The Navigation: Roomba robot vacuums have the best browser market. Conga cleaners are more chaotic and have a harder time getting to their charging station.

Autonomy: Cecotec has developed batteries capable of offering better performance than iRobot. In fact, they optimize them better even on high-powered models.

Durability: The materials, structure and design of the Roomba robot vacuum cleaners are of higher quality, which guarantees better resistance and longer useful life.

Price: the best Conga cleaner of the moment can be purchased, currently, for just over € 300. In fact, the bulk of its models is available for less than € 200. On the other hand, the best Roomba robot vacuum costs almost € 1200 and the cheapest versions exceed € 300.

Dirt Detector: Another feature that iRobot models win. These have the best dirt detector of the moment and, based on it, activate automatic intensive cleaning modes.

Taking all this into account, it is clear that the Cecotec Conga floor cleaning robots offer a better value for money and are aimed at the public with less purchasing power. However, the iRobot Roomba focuses on technological innovation and high performance, even at the cost of creating a more elite and exclusive device.

Alexa compatible robot vacuum cleaners

Alexa is the name of the virtual assistant developed by Amazon and called to compete in the market with Siri, Google Assistant and Cortana, among others. It has the ability to respond to voice commands for the purpose of playing music, setting alarms, and controlling smart devices such as cleaning robots. Controlling electronic devices through our voice is possible with artificial intelligence assistants like Alexa This virtual assistant is installed, by default, on Amazon Echo speakers. This allows us to give orders to the smart cleaner without using the remote control or a mobile application. We just have to express it with voice and, automatically, the device will start working. But what are the top Alexa-compatible robot vacuum cleaners? Here we are going to refer to the most important ones:

iRobot Roomba i7 +: Right now it is iRobot’s best robot vacuum cleaner. It has a HEPA filter, integrated rubber brushes and a smart camera navigation system. Besides being compatible with Alexa, it is the only robot that sweeps and empties and cleans its tank by itself.

ECOVACS Robotics Deebot N79S: a much cheaper alternative than the one mentioned above and to which we have already referred in this comparison. It’s one of the few Alexa-compatible robot vacuum cleaners for less than € 200.

Neato Botvac D7 Connected: intelligent laser navigation, spiral brushes, turbo mode and autonomy of 2 hours are the main arguments of this robot vacuum cleaner compatible with Alexa and with the dual-band of the WiFi router.

iRobot Roomba 670 Series (671, 675, and 676): the most economical range of Roomba robot vacuum cleaners compatible with Amazon’s virtual assistant. They have bristle rollers but lack smart mapping systems. Their prices range between € 230 and € 340.

IKOHS Netbot S15: another entry-level robot vacuum cleaner compatible with Alexa. Includes HEPA filter, mop, and a scrubbing attachment. They also include a special brush for pets.

How to choose a good robot vacuum cleaner?

Later we will talk about the characteristics of any robot sweeper and a vacuum cleaner that we must look at before deciding on one model or another. However, there are other aspects as important as those that will determine if we end up taking home the recommended robot vacuum cleaner for each of us or not: Robot vacuum cleaners help keep your home clean and some models can be programmed.

Types of robot vacuum cleaners: a distinction must be made between cleaning robots that sweep and vacuum and those that also scrub and mop. Obviously, the former is cheaper than the latter. In fact, it is possible to find such smart floor cleaners for less than € 100 even.

The type of floor: there are effective robot vacuum cleaners on hard floors, that is, those that have been specifically designed for tiles, and others more suitable for flooring and parquet, which are more delicate surfaces. The former offers greater suction power and the latter treat the floor more gently to avoid scratching it.

Are there rugs at home? eye! Robot vacuum cleaners for carpets have special sensors and features. This is because, when they get on them, they can get stuck and stop if they are not prepared. The same goes for smart carpet cleaners.

And pets? The dogs, cats and pets, in general, do not usually take too well with vacuum cleaners robots. This is mainly due to the noise they emit when cleaning. If you have a pet, you have to look for a special model for pets that is as silent as possible. Later, we will have to accustom them to the device.

The use. Are we going to use the robot vacuum cleaner on a daily basis? Or will we only activate it a couple of times a week? This is an important issue and one that should make us pay special attention to whether the model has a charging station, autonomy, suction power and the ability to program the device to clean when we are not at home.

Features to keep in mind

There are characteristics that we must know and that will help us determine which robot vacuum to buy. These are:

The capacity of the dirt tank: this characteristic will determine, together with the battery, the autonomy of the robot vacuum cleaner. In the case of looking for a floor vacuum cleaner for large surfaces, the tank must be at least 500 ml. On the other hand, for small spaces, 250 ml can be more than enough.

The battery: most smart floor cleaners have batteries between 2600 mAh and 5200 mAh capable of offering a range of between 90 and 180 minutes, approximately. Obviously, as with the suction power, this is one of the aspects that most influences the price of robot vacuum cleaners.

The function of scrubbing and mopping: floor vacuum cleaner also has the ability to scrubbing and mopping will make life much easier and comfortable. They are more expensive, but the investment is probably worth it.

The suction power: this is one of the first aspects that we must take into account when making a comparison of robot vacuum cleaners. The larger it is, the more able to clean the floor it will have. This is especially important in the case of those of us who have children and pets and who need to vacuum intensively regularly. Most models range between 50W and 100W of power.

The charging station: if our automatic floor cleaner has this complement, we will not have to worry about charging it after each use.

Remote control: nowadays, there are very good offers of robot vacuum cleaners with remote control. These allow being controlled remotely from the comfort of the sofa, for example.

Scheduling: This feature refers to the ability to schedule the automatic vacuum cleaner in advance. This can be done through the remote control or even a mobile phone. Many vacuum robots from Xiaomi, iRobot and Cecotec have associated applications that only need to connect the device to the home WiFi network to be able to put it to work from work or from anywhere else.

The mapping: although this was an exclusive feature of the best robot vacuum cleaners on the market until recently, today it can be found in many mid-range models.

Thanks to it, they draw maps of the house and optimize cleaning to the maximum.

The level of noise emission: make no mistake, even the best robot vacuum cleaner on the market makes noise. However, not all models emit the same amount. Currently, an automatic vacuum cleaner that emits 60 dB at full power can be considered a silent cleaning robot.

Accessories and spare parts: the brushes, the HEPA filter or the mop of the robot vacuum cleaner are elements that wear out over time and need to be replaced. Therefore, we must always trust a brand that gives us the possibility of permanently acquiring them.

How a robot vacuum cleaner works

Robot vacuum cleaners allow us to clean the house quickly and effortlessly as they operate completely autonomously. However, how exactly do they work? This is somewhat more complex than it may seem. First of all, it doesn’t matter if we buy a cheap robot vacuum cleaner or opt for a high-end model.

The device will have a series of proximity sensors and damping systems. This is mainly due to the fact that they can detect obstacles (walls, steps, tables …) and hit them gently so as not to damage them while cleaning the corners closest to them.

For their part, the best robot vacuum cleaners have dirt sensors. These manage to detect especially stained areas of the floor. When they do, they automatically activate intensive work modes to leave them gleaming. At the bottom, there are, on the one hand, two or more circular brushes, which are responsible for attracting dust and dirt towards its suction opening.

These rotate counter-clockwise for this purpose. In addition, they incorporate a roller with brushes that is responsible for sweeping the floor while they vacuum. The collected dirt is stored in a tank with a HEPA filter that must be emptied and cleaned after each use.

If it is a robot that vacuums and scrubs, both the roller with brushes and the circular brushes can be replaced by a mop and a rubber cylinder. In addition, they also allow the change of the dirt tank for a water one.

The best robot vacuum cleaners on the market also have cameras and mapping towers or sensors. Thanks to these components they can scan the house and create a map that, later, allows them to clean more effectively.

In fact, these are the only models that guarantee total cleaning of the floor in each use. Virtually any cleaning robot already has a charging station from which to recharge its battery.

In this sense, when the device detects that its autonomy is coming to an end, it travels only to the place where said charging point is located and is attached to it. This is possible thanks to a signal emitted by both devices and that helps the vacuum cleaner to orient itself to the indicated place.

Best brands of robot vacuum cleaners

Today, within the market it is possible to find dozens of companies specialized in the production of robot vacuum cleaners. However, not all of them are equally popular or offer the same quality standards in their models. Therefore, here we are going to review what we consider to be the 5 best brands of robot vacuum cleaners.

iRobot (Roomba)

Probably the best robot vacuum cleaner brand, or at least the pioneer and one of the most famous brands. Based in the American city of Burlington, Massachusetts, and founded by Rodney Brooks, Helen Greiner and Colin Angle after years working at MIT, it is responsible for the marketing of the Roomba robot vacuum cleaner.

Without a doubt, iRobot robot vacuum cleaners boast of having the leading technological innovations of the moment before any other. As a curious fact, the company also designs and produces explosives disposal robots under the Packbot seal. These are used by practically all the armies of the countries that make up NATO.

Cecotec (Conga)

The brand of robot vacuum cleaners is capable of competing for face to face with iRobot within the market. It has Spanish origin and was founded in 1995. However, it is not specialized exclusively in the production of this type of cleaning device, but in a wide range of small household appliances. In it, you can find deep fryers, kitchen robots, hand, broom and sled vacuum cleaners, or programmable pots, for example.

Cecotec is the brand responsible for designing, manufacturing and selling the Conga robot. This is, in its different versions, the most sold in Spain. The excellent value for money of the models it sells is the main reason why this is so.

Ecovacs (Deebot)

It is true that iRobot and Cecotec dominate the bulk of the robot vacuum market. However, there are alternatives that, although less known, offer excellent quality standards.

This is the case of Ecovacs, a brand of Chinese origin founded in 1998 in the city of Suzhou and which specializes in the production of robotic devices for the home.

Currently, Ecovacs Robotics is estimated to comprise more than 60% of the robot vacuum cleaner market in China. Their models are marketed under the Deebot name and there is a very wide variety that covers a multitude of price ranges. Without a doubt, this is a very interesting option for those who want to buy a quality Chinese robot for a fairly reasonable price.

ILife (A and V)

Ilife should also be considered as an excellent alternative when buying a robot vacuum cleaner. Also of Chinese origin, it was founded in 2010 and, since then, has made a clear commitment to innovation in this type of automatic cleaning device. In fact, it has three own R&D centers and invests 10% of its profits each year to research new technological systems applicable to these devices.

Currently, Ilife divides its catalog of robot vacuum cleaners into two sections. On the one hand, we must speak of the A models, which offer excellent suction power and high efficiency on carpets and hard floors. They are also perfect for homes with pets. On the other is the V series, within which it is possible to find robots that vacuum and scrub.

Xiaomi (Roborock, Mi Robot, Mi Vacuum and Xiaowa)

Xiaomi is a fashionable technology firm thanks to its smartphones, its activity bracelets, its wireless speakers … and, of course, its robot vacuum cleaners. In fact, of all the brands named here, it was the last to jump on the bandwagon of automatic cleaning devices.

Specifically, Xiaomi was founded in 2010 in Beijing, China, and did not inaugurate its catalog of Roomba-type vacuum cleaners until 2015. Today, it has four different ranges: Xiaomi Mi Robot Cleaner, Xiaomi Roborock, Xiaomi Mi Vacuum Cleaner and Xiaomi Xiaowa. As is usually the case with all the brand’s creations, these are cleaning robots that stand out for their value for money and are capable of offering technical specifications that, until now, seemed reserved for high-end models. Without a doubt, alternatives must always be taken into account.

In short, the robot vacuum cleaner market in 2019 is loaded with novelties and models of high efficiency and performance. We are confident that our readers will be able to determine the perfect smart floor cleaner for them from the information we have just provided.
