Power of Vacuum Cleaner – Things You Need to Know

When it comes to choosing a new vacuum cleaner, power is very often the element that seems essential. The logic is that the higher the power of a vacuum cleaner, the better your Vacuum Cleaner will perform. It is, unfortunately, not so simple. There are several data to consider when choosing a vacuum cleaner to determine its power.

Indeed, to define the suction power of a model, it is necessary to distinguish the power consumption expressed in Watts. It’s not easy to find your way through vacuum cleaner data sheets. Which sometimes leave you wondering about the complete characteristics of the products.

To help you, here we explain everything you need to know about the power of a vacuum cleaner. Never forget to see the Buyers Trend of a market before buying any product online. It will assist you to stay in trends that what exactly people are buying nowadays. Also, this will allow you to increase your level of choice as well.

Essential Criteria You must take into account

When we talk about suction power, actually we are talking about several things: on the one hand, depression and airflow. It is a set that is called the useful power and which corresponds to the ratio between this depression and this airflow.

On the other hand, we take into account the electric potential of the vacuum cleaner. Important for you to assess the power of vacuum cleaner before Important for you to assess the power of vacuum cleaner before ebefore buying any vacuum cleaner. Expressed in watts, which corresponds to its energy consumption. Depression and airflow (useful power) provide information on the vacuum cleaners ability to lift dust and carry it into the tank.

The ideal ratio of vacuum to airflow is 40 kPa/40 dm3/s. The depression is expressed in kPa (in kilos Pascals), and it lets you know how fast the vacuum cleaner sucks the dust. Depression is thought to be:

20 to 35 kPa for smooth soils

About 40 kPa for hard floors (such as carpets)

It will allow you to suck quickly without having a suction effect that makes the brush sticks to the ground. Regarding the airflow, it is expressed in (dm3/s) (cubic decimeter per second). This element indicates the ability of the vacuum cleaner to transport dust from the ground to the tank, via the amount of air flowing through its tube every second.

The ideal is

36dm3/s minimum for smooth floors

More than 40 dm3/s for hard floors

It is the combination of these two elements that allow you to know the real power of your vacuum. Too often, users trust only one of these elements and end up with vacuum cleaners with unbalanced force. It results in too strong suction for some floors or not capable enough when it is necessary to suck animal hair or dirt-encrusted in carpets and rugs.

Power of a Good Vacuum Cleaner

Most of the times, datasheet of a vacuum cleaner puts forward its electrical consumption expressed in watts rather than power. Inattentive consumers will, therefore, be fooled by this high figure which is only partially representative of the real power of a vacuum cleaner.

Indeed, it is the useful power of the device that will determine its ability to suck the dust, hairs or other residues that are scattered in your home. It is recalled that the ideal ratio between the vacuum and the airflow must be 40 kPa/40 dm3/s.

This proportion is crucial because too much useful power can cause problems. A vacuum cleaner that sticks to the ground during suction, for example, which will tire you excessively during your household. Then, take note of its suction power expressed in Watts and take into account your frequency of use.

If you use your vacuum cleaner from time to time, not intensively, a power of 1800 watts is sufficient. For more regular and more intense use, then it is advisable to choose a model with a force of 2400 watts maximum.

The choice on the Basis of Power

Depending on how you use your vacuum cleaner, your decision may vary. There are many different models, variable power, which all correspond to a type of use. We have prepared for you this detailed article which will help you to choose among the many references of the market.

Whether you opt for a vacuum cleaner with or without a bag, a broom vacuum, a robot vacuum cleaner or a hand vacuum, you will find in our tests and our advice to help you make the right choice. If we can give you a little trick, it would be to choose a vacuum cleaner that has a power aviator. It is for ecological and economic reasons.

Indeed, with a vacuum cleaner, you can adjust the power depending on the soil you clean, you avoid over-consumption during your household. It will be felt on your bill, on the one hand, but also during cleaning. At low power, some vacuums turn out to be almost silent so you can vacuum at low power to enjoy your favorite TV series while effectively cleaning your home.

Robot vacuum cleaners are also pleasant to use for this reason. But you should know that brands, more and more, tend to offer models that combine power and quiet function.
