Main things to consider before buying the ultimate drying weapon

Avatar of Thomas Grimm



When doing laundry at home, one of the fundamental points is the clothes dryinga process that we can carry out in very different ways, either naturally with the classic clothesline of a lifetime, with different tricks to dry quickly without spending a lot of light or directly using an electric dryer.

Until a few years ago, these electrical appliances were scarce in our country since we generally have many hours of sunalthough it is also true that there are regions where the level of environmental humidity complicates the usual drying of clothes in the air and with an electric model we can also speed up the process and obtain other advantages.

What are the main reasons for buying and using an electric dryer at home and what advantages and disadvantages can you provide us? Next we will review the most important ones.

How to dry clothes inside the house without wasting light and avoiding bad odors and humidity

Types of dryers and basic characteristics


There are basically three types of dryers: the so-called evacuationthe of condensation and the most modern ones that incorporate a heat pump. All of them fulfill the same mission: to apply hot air to dry the clothes, although they do so with great differences in terms of the way of heating this air and managing the exiting humid air.

  • The evacuation dryers They are the most basic of the three, less efficient and almost out of use. They are less and less common in stores but can be interesting for sporadic use. In addition, they require a exit to the outside of the house to release the air laden with moisture.

  • The condensing dryers They do not need an external outlet, since the humidified air loses its water in a condensation process, depositing it in a container located inside the appliance. They take advantage of contact with cold materials to condense moisture. To do this, they first heat the air with an electrical resistance and then it is passed through the drum. In this process, the hot air is humidified.

    After this, the hot and humid air passes under the drum and its circuit is crossed by a current of cold air. On contact, hot, moist air cools and dries. These types of dryers can consume between 1,500 watts for partial loads and more than 3,000 watts for drying cycles of complicated loads, for which its electrical cost is important.

  • Unlike dryers that heat the air using electrical resistances, heat pump dryers They work by reheating the circulating air in a similar way to air conditioners. They have two closed loops that work together to maximize efficiency.

    The first is a circuit with a air exchanger and several layers of filtering that dries clothes. And to raise and lower the air temperature, a refrigerant circuit. Thanks to this technology consume less energy in the process, so they are more efficient, but they also come at a higher price. The most efficient can consume from about 800-900 watts for short or medium load cycles and some 2,000 watts for full loads.


Beyond the technology used to generate hot air and extract humidity, there are also other features and functions that should be taken into account:

  • First is the dryer load capacity: measured in kilos of clothes that you can put in at once. The more capacity, the more clothes we can dry and since wet clothes weigh more than dry clothes, it is convenient to choose a model with more capacity than our washing machine.

  • installation requirements from the dryer. If you opt for an evacuation dryer, an exterior outlet will be necessary. In case of choosing a condenser dryer with a drain option, you will also need to have the outlet nearby.

  • Apart from having programs for the different fabrics of your wardrobe, it is interesting that it incorporates others such as the anti-wrinkle functioncold air for delicate garments, quick drying for emergencies, deferred end or delayed start so that you do not have your clothes in the drum for longer than necessary

  • It is also interesting that some allow download specific programs and we may be interested in being compatible with voice assistants (usually with Google Assistant and Alexa), so that we can integrate them into our connected home by implementing routines or simply to control them through voice commands.

  • Another important point to consider is the energy efficiency. With the entry into force in 2022 of the new efficiency labels, the dryers are classified from the letter A to G (from highest to lowest efficiency). The most efficient models are those of heat pumpso even if the initial investment is higher, in the long run they will be more profitable.

Advantages and disadvantages of using dryers at home


Once we have already reviewed the characteristics and functions that should be taken into account when buying a dryer, we are going to know which are the main ones advantages and disadvantages to have one of these appliances at home.

  • To begin with, using electric dryers will allow us to protect our garments from the sun’s rays. The ultraviolet light that heats and dries clothes on outdoor clotheslines can be damaging to fabrics, causing them to age faster and even break down.

  • And if we choose to use the classic indoor clotheslines or simply to put the clothes on radiators or near stoves in winter, what we will be doing is transfer moisture from clothing to the air from inside the house, which in cold times can reduce the comfort of the environment.

  • Another advantage of using these electric dryers is not depend on the weather to do the laundry. It doesn’t matter if there is no sun or it is raining. We can wash and dry clothes whenever we want without looking at what the weather is going to be like.

  • It also allows us to do laundry at any time without depending on whether it is daytime and sunny or having another heating source turned on at home to dry clothes.

  • As an inconvenience we find that we will have one more device at home which is an initial expense and you also need to be able to count on a proper place to install ithabitually occupying as one more washing machine.

  • Dry the clothes we don’t get free anymore as if we tend it to the sun, since dryers are electrical appliances that in general can mean a significant increase in the electricity bill. This will depend on how many times we use them a week, how much load and how wet the clothes are when they come out of the washing machine.


As we can see, the reasons for having or not having a dryer at home are very varied and will depend in the first place on our habits and needs when doing laundry, something that varies, for example, if we are large family with small children They get very dirty and we need to wash and dry clothes frequently.

But the choice of our place of residence will also condition us. If we live in one area with many hours of sun At the end of the year, where it is generally hot except for a few specific months, it is probably more worth hanging out in the open air, even if it is inside the house, taking advantage of the classic tricks or the most modern devices that help us to dry clothes only in those cooler and wetter days.


If instead we live in a area with high humiditywhere it rains frequently, there are few sunny days and hanging clothes inside the house means having a very humid environment that is harmful to health, then a dryer can be our best friend when it comes to doing laundry.

what they are, types, advantages, disadvantages and models from 180 euros

Avatar of Thomas Grimm



at the time of produce our own electricity at home Typically, we think of photovoltaic solar panels or panels, a technology that takes advantage of the sunlight to feed our equipment and appliances with a relatively high initial cost if we want great power.

However, there is another option that is gaining more and more strength, especially if we have a single-family home, with a clear roof, garage, large terrace or with a small patio or garden at our disposal: domestic wind turbines. (more…)

in which cases it is essential to bet on a top-of-the-range robot vacuum cleaner and in which not

Avatar of Thomas Grimm

Let’s go ahead that today the intelligent navigation essential for mapping has been democratized, so that we can find it not only in the high and medium range, but also in moderately affordable robot vacuum cleaners (even under 200 euros). But either by investing the minimum essential in this autonomous broom substitute or because we do not want a robot vacuum cleaner to draw maps of our house under any circumstances, there are those who choose to do without this feature. Buy a robot vacuum cleaner with or without mapping?

why map

Lets start by the beginning. Mapping consists of the fact that the device has the Technologys that allow it to deduce what the environment will be like to sketch a map. The direct consequence is that you can draw meaningful navigation paths (the logical thing to do is to sweep by rooms, not start sweeping part of the kitchen, leave it halfway and go with the living room), so you make sure that covers the entire* area with just enough passes.

And that asterisk in “everything”? The reality is that there are obstacles such as cables, pots, feeders, legs and cracks that the vacuum cleaner does not pass through, either because it is physically impossible for it to fit or because its algorithm determines that it does not fit (generally when it has little clearance).

That it does not go too far is important, firstly because it optimizes its operation and the long useful life of its components, secondly because thanks to not wasting resources, it can cover and clean more space. Finally, because if you are at home, listening to the robot vacuum cleaner in full action is a drag. Better clean up as soon as possible.

The normal thing with a robot that maps is that you can view the map in the app and that also brings benefits. Thus, there are quite a few models that offer a color graph that distinguishes the areas that have been cleaned from those that have not, ideal for you to take note and remove some elements that make navigation difficult.

But the great advantage of mapping has to do with partial cleanings. Yes, you can resort to the classic and ancient virtual barrier (an element that simulates a virtual limit for the device) or proceed to the bravest taking the vacuum cleaner in your arms, drop it in a room and close the door to clean, but if your kitchen is dirty after preparing food or your bathroom has turned into a post-apocalyptic place after your child has showered and cleaned up, the ideal is to go to the phone, open the application, select which area or room you want it to clean and let the action begin. In a few minutes and without further need for your intervention, the floor of the area would be clean again.

In any case, if a robot maps it is because it has some kind of intelligent navigation system that will help you move better than without it, allowing for more effective cleaning, minimizing the chance of getting lost and also getting stuck around. That he does not clean a part of the house is a problem, that he pulls the cord of the lamp, throws it on the floor and breaks it is a chore.

Not related to mapping, but to note: models without mapping are entry-levelwhich generally implies more rudimentary handling (perhaps manual and remote controlled) and basic cleaning Technologys (don’t expect special rubber center rollers for pets).

Best price-quality robot vacuum cleaners: which one to buy based on use and six recommended models


How robot vacuum cleaners navigate

The state of the art of robot vacuum navigation. As we anticipated in the intro, nowadays finding smart mapping and navigation is not only unusual, but the exception are models that do not map. But there are mappings and mappings.

The highest range of robot vacuum cleaners is mostly taken over by models with a multi-navigation system with a laser sight and a front camera which, in addition to allowing maps, serve to recognize objects. Map and objects usually appear in the application, so that we know what problematic things are on our floor. Under the hood, a processor, algorithms and even artificial intelligence to make decisions: ignore it and try to go over it or avoid it.

This is essential because that way you can avoid what was Worst cleaning day of my life: that fateful date when Lola felt unwell, she planted a pine tree in the corridor, the Roomba ran over it while cleaning and you can imagine the rest. Cleaning the floor of the house of excrement is not a pleasant dish, but having to disassemble your vacuum cleaner and waste time removing splinters… for me it stays.


The Roborock S7 MaxV Ultra has it “everything”: laser sight and front camera

Then there are models that they either just have a laser sight or a camera (although iRobot bets only on a camera placed on the front for mapping, navigation and recognition of objects in models like the Roomba J7 +). These models are more than enough for domestic mapping and optimized navigation, although to avoid accidents and loss it is best to leave the house as clear as possible.

And we close with the non-mapping. These robot vacuum cleaners have a combination of mechanical pressure sensors to detect contact with walls, infrared sensors to measure the distance to obstacles, optical sensors similar to those of mice to analyze movement, and fall-prevention light sensors that detect steps and unevenness. How do they navigate? Like you would if you were blindfolded and released into a room: with moderate caution and touching everything. The bonus is that they must also try to cover the entire area, so navigating randomly means taking a few more detours and turns.

Do I map yes or do I map no?

The good thing about robot vacuum cleaners is that they clean moderately well for you, which depends on their suction capacity, the quality of their brushes, that they are capable of covering the maximum space in your house and that they have a battery to do so.

Are you concerned about privacy? Here are two recommendations: see how the manufacturer manages this data related to our architecture and its objects (essentially, if they stay on the device or if they go to a server, if there is data encryption) and the premise that Although on paper there are protection systems, logically there is always some risk. The second is to weigh this fear against what you earn.

When is it essential to have mapping? If you have a large house and/or with several floors, you want to do partial cleaning or you simply expect the best results from a vacuum cleaner, then your thing is to bet on efficient navigation. No matter how much battery a robot with random navigation has, it is highly difficult for it to clean a large floor well and it is not so much a question of size as of obstacles: it can already have autonomy of 300 minutes, which if it gets stuck at minute 7, it will not be able. Another thing is that you have a completely clear ship.

Ok, but I still want to spend as little as possible, Is a robot vacuum cleaner without mapping worth it? Obviously having a robot vacuum cleaner is better than nothing and its effectiveness can be acceptable if we are clear about its limitations. In any case, it can be a good option if your budget is just over 100 euros, you have a small and/or sparsely furnished house that you agree to leave uncluttered, or you simply want an extremely basic model without connectivity (an example : to give it to your grandmother and she can control it with a remote).

the first approach to the big screen

Avatar of Thomas Grimm

After decades of making use of cathode ray tube televisions, several manufacturers began to launch televisions on the market that were considerably thinner and with a novel panel technology. We are talking about plasma televisions, which ended up revolutionizing the industry. It must also be said that there was such a powerful marketing campaign around this new technology that even today you can find people thinking that they are still the ones that offer the best image quality.

And it is that the manufacturers of TVs made sure that when someone talked about plasma TVs, they were talking about a product synonymous with quality and high-end. For a while it was like that because the evolution compared to the old CRT was considerable. In this article we wanted to pay tribute to this type of television, mentioning its origins, what its technology consisted of, and its successors.

It took decades to see the first plasma television

Although the plasma display was developed in the 1960s for the PLATO (Programmed Logic for Automated Teaching Operations) computer system by a group of researchers from the University of Illinois, it was not until the late 1990s that to commercialize televisions with this technology. During all that time there were monochrome screens (orange, green or yellow), very popular for their hardness and because they detached from elements such as memory or circuits to update the image.

Image: Wikipedia

In 1973, IBM developed an 11-inch monochrome display with this technology, accompanying the IBM 3270 computer and making it capable of displaying up to four terminal sessions at once.

The Plasmaco company, founded in 1983, also played an essential role in the development of this technology. In fact, it was acquired in 1996 by Matsushita Electric Industrial, who in 1983 launched the Executive Partner, its first computer with plasma screen. The latter is known today as Panasonic, one of the companies that has most promoted plasma technology.

2023 is going to be a spectacular year in televisions: this is what the main manufacturers are preparing

When Pioneer launched the first plasma television to the public in 1997, the technology began to catch on in a big way, promising larger screens and better image quality and brightness.

Much larger panels with higher image quality

The plasma television has a set of small cells located between two glass panels. These contain a mixture of noble gases (neon, argon and xenon) that after charging the electrodes creates a voltage difference between the rear and front, causing the gas to become ionized and change its state to plasma. After this process, the ions of the gas move towards the electrodes, where they collide and generate photons, thus causing the emission of light.


Image: LCD Repair

This technology allowed to manufacture televisions with much more brightness than tube TVs. In addition, they were popular given their larger size, since in the market we could find plasma televisions larger than 70 inches.


In terms of image quality, it was an incredibly noticeable leap, with a greater color gamut and deeper blacks than LCDs, given its low luminescence. However, they were televisions that got too hot, being unpleasant for the user in the case of spending long hours with the television on. In fact, as with OLEDs, in plasma televisions there was also the fear of burning the panel.


In the market we could find all kinds of plasma models of different sizes. Manufacturers such as Pioneer, Panasonic, LG, or Samsung, among many others, showed the world the capabilities of this technology in televisions, which became very popular, although yes, significantly more expensive than CRT TVs.

The price and its stagnation buried this technology

The price disadvantage, and the need for the panel to have a large diagonal for its manufacture, meant that the plasma television became part of a highly concentrated market. Secondly, LCD technology kept growing. And it is that although the first LCD televisions were notably inferior to plasma, little by little they were conquering the public, eventually tackling the problems of dead pixels or ghosting of the first generations.

During the last years of life, the plasma barely reached 5% of the market sharein a context in which brands such as Samsung or LG dominated the market for flat screens with LCD technology.

In 2014, most plasma TV manufacturers finally abandoned the technology, although it ceased to be relevant several years earlier. However, it will always be remembered as one of the Technologys that most helped advance the image quality of televisions.
