Dyson V12 Slim, analysis: the effectiveness of always with more lightness than ever

One of the strengths of cordless vacuum cleaners is the comfort and manageability that operating without cables gives, but the truth be told: sometimes the combination of motor, tank and battery results in a device that can be heavy and not very ergonomic. For those seeking maximum lightness without giving up cleaning solvent specifications, the British firm has launched this Dyson V12 Slim, which we have had the opportunity to thoroughly test in its “Complete” version.

Those lines, those finishes, those garish colors… when you see the Dyson V12 Slim you can’t help but say that “Your face sounds familiar to me”. And this is good news: the use of aluminum and plastic characteristic of the Dyson offer resistance, moderate lightness and a perfect fit of the pieces (in terms of speed and absence of gaps).

Of course, for the more experienced eye that has already had to deal with some of the latest releases of cordless vacuum cleaners from the British house, such as the Dyson V11 Absolute Extra or the Dyson V15 Detect Absolute, we appreciate two fundamental differences: the head of Dyson V12 Slim is somewhat more compact and lighter and also lacks a trigger in favor of a striking red button.

It is worth dwelling on its size and weight because it is one of its differentiating factors. With up to 60 minutes of autonomy typical of the most complete models and a slightly less powerful engine, the trick of its lightness is in the tank, much smaller than his older brothers. And the consequence is clear: you are going to have to empty it more.

Little mystery has his big red button: Press to turn the vacuum on or off. With this design you will always spend a little more battery than trigger models, in that you lose a few seconds of not vacuuming to stop it. But neither is it something that makes a difference and in return, you avoid having to force the posture of your hand and wrist.

The trick of its lightness is in the tank, much smaller than usual in Dyson cordless vacuum cleaners

That it is lighter than usual and that it does not force us to be squeezing results in the Dyson V12 Slim is the most interesting cordless household vacuum cleaner for people of a certain age and/or with physical problems, for example muscle or joint. Come on, it’s the one I would recommend to my mom, who often complains about the weight of braces and has arthritis.

The rest of the vacuum head is very similar to the rest of the family, with a consolidated design that is moderately ergonomic and practical. In this sense, we highlight the position of the battery, in the lower and removable area, and how easy and fast it is to clean the tank and filter area.

Very useful is the screen that you will find on the back of the head, right in front of your eyes, which will allow you to know in real time its autonomy with the mode you are using and switch between one and the other by pressing the button next to it.

Which Dyson cordless vacuum cleaner to buy: best recommendations based on the use of the vertical vacuum cleaners in its catalog


In one sentence: the Dyson V12 Slim Absolute is enough for cleaning the entire home. And it is for four reasons: its power meets even in difficult scenarios such as carpets, its accessories make it versatile, its autonomy is among the best on the market and it is comfortable in hand. Of course, it is not perfect and it has certain limitations as we will see.

  • floor cleaning. Probably its best asset is this scenario, where low or medium power is enough to deal with daily dirt. Although it is not as comfortable as a robot vacuum cleaner that operates autonomously, a floor of 55 square meters is cleaned in less than 10 minutes and obviously, you can affect the dirtiest areas and reach the corners. The lighting of the brush is a plus so that we do not miss anything.

  • It has little to envy the sled vacuum cleaners in cleaning rugs. In this sense, with several passes, maximum power and the right accessory, the rug looks great both visually and by waving it in the air. Of course, if you have a flat of 100 square meters or more with carpet and it is very dirty, then its autonomy does fall short. But for a couple of rugs, it is more than enough for both deep cleaning and maintenance.

  • One of my favorite tasks during these analyzes is to take advantage of a good domestic cleaning spree where the aspiration of mattresses and other textiles such as sofa, another cleaning scenario where this vacuum cleaner shines. Here you will greatly appreciate how manageable it is and accessories such as the multifunction or the mini brushes. In a home without pets like mine, the medium power is enough to leave the sofa spotless.

  • And the car? Due to how manageable it is without cables, the accessories and its power is enough for superficial maintenance cleaning, but if your car is very dirty or you have pets, then it will fall short. Elements such as the mats or the trunk are real dirt magnets and to get rid of them you will have to use maximum power, which eats up the battery. But if you resort to industrial cleaning with some frequency, it will be enough to keep it decent.

Power vs autonomy

Image 3269

In the previous point we have already gone over power and autonomy, two essential characteristics to be successful when choosing a good cordless vacuum cleaner. According to the manufacturer, the Dyson V12 Slim offers up to 150AW of power and up to 60 minutes of use, although it is not possible to have the combo of the two: if you opt for maximum power, do not expect more than XX minutes of autonomy.

Thus, these are the modes and the autonomy they offer:

  • The boost mode It is the maximum power and with it you can vacuum less than 8 minutes. Why less? Because as soon as the battery is running low, the vacuum cleaner automatically switches to a less ambitious mode. The Boost is ideal for textiles such as rugs or for vacuuming the floor if you spill the contents of the tank, something that happened to a friend (Note: the friend is me).

  • With the medium mode its autonomy is around 32 minutes. In my analysis, this has been the mode that I have used the most for cleaning floors and textiles.

  • If you only want to clean the floor, you do it regularly and there are no pets in your house, with the echo mode You’ll have more than enough (less than 53 minutes in our experience). The good thing is that the approximate hour of autonomy it offers gives you for several days.


Both on the web and in the manuals you will find how to do it, request spare parts or repairs. In your day to day, what you will do most is clean the accessories, the filter and, given the size of your tank, clean it frequently.

I already warned you that the cleaning of the deposit is sewing and singing: Stand on top of a garbage can and pull the red tab down to open the lid and drop the dirt out. From here, you can always reach in to clean it more thoroughly.

The Dyson are always positioned in the upper mid-range of vacuum cleaners and it is easy to ask yourself, before choosing one, if it is worth investing more money than in other similar more affordable models. As well, one of the strong points of the Dyson is its durability: they are vacuum cleaners for the long term.

The Dyson ones are expensive, yes, but you have a vacuum cleaner for many years.

Apart from the fact that they are well made, they are robust and their accessories are compatible with each other (if you had a corner unit from the Dyson V10 for example, you can use it with this model), the best thing is that its battery is removable.

What does this mean in practice? That when its autonomy is reduced over time as a result of use, you can buy another original or compatible battery and you will have its original autonomy again. In addition, you can replace it yourself, without having to disassemble anything. You can also buy another unit and thus “double” its autonomy. They are expensive, yes, but you have a vacuum cleaner for many years.

Dyson V12 Slim, Xataka’s opinion

If you are clear that you want a Dyson cordless vacuum cleaner, the main differences between the models (and their cost) are in autonomy, accessories and power. Of the first two, this Dyson V12 Slim Complete version is well served and in terms of power, it has measured up in common scenarios such as floors, carpets and other textiles. Where it falls shortest in this sense would be in the car, but we already warned you that the house’s more ambitious models have also succumbed to pet hair embedded in the textile lining the trunk. After all, they are not vacuum cleaners for industrial cleaning and yes for domestic cleaning and here it approves with a note.

This light version results in more manageability and anyone appreciates that, even if the price to pay is having to pay more attention to emptying the tank. The question to be asked has to do with your needs: More power or lighter? A matter of taste, but personally I have noticed that extra manageability more on a day-to-day basis.

Although on the web the difference in price between the Dyson V15 and the Dyson V12 is 200 euros, in practice the first can be found for 649 euros and the second for 689 euros, so the savings will not determine the choice too much. If we compare it with other cordless vacuum cleaners on the market, the reality is that like the rest of Dyson, this is an expensive model.

Now, it is a matter of thinking about needs and the long term: the suction results are optimal (like many others), the accessories are of quality and easy to replace (here other alternatives already falter) and the commitment to durability with that practical removable battery are a guarantee of using it for many years. Y here the accounts come out.
