Best robot vacuum cleaner

Which is the best robot vacuum cleaner 2021: a guide to choosing which robot to buy

It is clear that if there is currently a device that has entered with force in the houses and homes, that is the robot vacuum cleaner (or cleaning). For some time now, we have found models for all tastes, needs, and pockets to keep lint and dust at bay at home without lifting a finger and almost always controlling the robot from the mobile.

When it comes to getting a robot vacuum cleaner, we must take into account or at least, it is advisable, to control a series of aspects: the design of the robot, the connectivity or integration in the smart home, the functions, the type of cleaning … They are all factors that can influence our decision and that is why we are going to review them before collecting some of the most interesting models on the market.

Robot vacuum cleaners have undergone an evolution since the first models arrived that offered performance that, let’s face it, left a lot to be desired. The most recent models have seen a great improvement thanks to the incorporation of new functionalities and features. Performance has greatly improved thanks to the integration of navigation sensors, dirt level detectors, integration with virtual assistants, or even equipped with ultraviolet light to disinfect surfaces.

Navigation systems

The guidance system is one of the elements that has evolved the most
Far are the robot vacuum cleaners that move randomly or those based on collisions with an obstacle and that, with a kind of rebound effect, continue cleaning on the other hand. 
Now the most modern models include navigation systems with the possibility of delimiting cleaning areas without using accessories to create virtual walls when moving through restricted areas. 
In this sense, and for those people who live in houses with several floors, it is interesting to find a model that can establish plans for the different bases on which they will work.
There are also robots that have an intelligent navigation system thanks to the incorporation of different types of systems. 
We are talking about unevenness and obstacle sensors, but also gyroscopes, cameras, using laser viewers … all of them that are in charge of analyzing the environment that surrounds them, creating a map of the area to move without having to collide with the furniture and household objects.

In addition, and as a complement, some models can integrate systems to determine the amount of dirt that exists, and in this way spend more time working in an area that offers a greater amount of dirt to be removed.

Autonomy

It is an important aspect since it determines that we can leave the house clean without the robot having to return to the charging base with a single charge. It is interesting that the chosen model has an autonomy that allows it not to have to return to the charging base and that is why it is important to optimize navigation, which is what we mentioned in the previous section.

The normal thing is that in a home of around 100 square meters (we have to consider that there is a space occupied by furniture, toilets, and other utensils), almost any model offers the necessary autonomy to cover cleaning with a single charge. We can find on the market models that offer from an hour and a half to more than three hours, and to improve the use it is necessary that it has an intelligent navigation system that avoids unnecessary energy expenditure “going around” without sense.

In addition, it is a more than interesting factor that our robot can establish cleaning programs. In the more advanced models, we can find how they offer more efficient programming functions to determine from the hours or days in which to clean and even to program which areas of the house we want to clean at certain times.

The importance of filters

Filters are an essential element because when the robot cleans with the brushes, dust and particles can be raised and added to the suction airstream. The robot not only removes hair, dirt, and dirt in general but also collects dust and other microparticles, so it is essential that it incorporates a high-efficiency filter to maintain clean air in the home (because if not, it will be removing everything at home and that’s not what we want).

That is why the ideal is to look for a model that makes use of a HEPA filter (High-Efficiency Particulate Air) and here, as we already saw in purifiers, we should not confuse HEPA filters with HEPA filters. Thanks to HEPA filters, all particles equal to or greater than 0.3 microns in diameter can be trapped with 99.97% effectiveness according to established standards.

Cleaning capacity

We are talking about vacuuming and using a brush system. In the first aspect, you have to look at the suction capacity of the robot in question. We will find models that have power close to 1,500 Pascals up to the most powerful, which can be around 10,000 Pascals.

The suction capacity is related in a very particular way to the brush system offered by each model. The usual thing is a large central silicone brush with hair bristles located across the entire width of the robot that collect the bulk of the dirt to which, in some models, accessory brushes can be added on the sides in a helical shape.

And also related, we can’t stop talking about noise. It is important to know the sound level that it generates during cleaning since many times it is something we do while we are resting at home. That is why it is interesting to look for a model that generates a low noise level. Normally the usual figure for a cleaning robot is between 50 and 80 dB, so that the closer that figure is to that 50 dB, the more comfortable it will be to use our robot.

The importance of connectivity

One of the aspects that we can value the most is the connectivity offered by a given model. Beyond turning the robot on and off in situ, it is interesting that we can control it from the mobile, either through its application or through its integration in the different platforms for the control of the connected home such as the environments of Apple, Google or Amazon.

In addition, the fact that they can work with voice assistants such as Alexa, Google Assistant or Siri, allows that the cleaning can be executed with a voice command, from the mobile, a connected speaker, or another compatible device and also do it from any point. In this way, we can start cleaning, establish limits on where it should or not clean, and even receive notifications with any problem that may arise during the process.

Five models of robot vacuum cleaners that we recommend

And once we have seen some basic parameters when deciding on one or the other model, it is time to choose from the catalog of alternatives that we can find in the market, but we will leave that for another article. Meanwhile, we recommend five models of different prices:

Cecotec Conga 1790

One of the cheapest models is this one from Cecotec. A robot that sweeps, vacuums, mops, scrubs, and what can we find for 179 euros on Amazon. With a power of 2,100 Pascals, this model has the SmartGyro 3.0 mapping system that uses proximity and anti-shock sensors to improve cleaning. We can control it from the mobile, and it is compatible with Alexa and Google Assistant.
