Best Powerful Vacuum Cleaner with strong suction power

In short: the power of a vacuum cleaner is expressed in suction power. In all my reviews I measure the suction power of vacuum cleaners in kilopascals (kPa). This allows me to compare vacuum cleaners on strength and to list the most powerful vacuum cleaners.

Most powerful vacuum cleaners I’ve reviewed:
Best Powerful Canister Vacuum Cleaner: Miele Boost CX1 (21 kPa)
Best Power Stick Vacuum Cleaner: Dyson V15 (10 kPa)
Best Powerful Handheld Vacuum: Turbotronic Lux400 (8 kPa)

It is perhaps one of the most important factors of a vacuum cleaner: the suction power. Good suction power ensures that you can thoroughly clean the floor and that there is an enormous dust absorption. People often think ‘the more watts, the more powerful the vacuum cleaner’, while this actually says nothing about the suction power of a vacuum cleaner.

In my reviews I research the power of vacuum cleaners. I do research into both the suction power and the air speed to get a good idea of how strong a vacuum cleaner actually is.

Most powerful vacuum cleaners at the moment

At Vacuumtester.com we test the power of different types of vacuum cleaners. From compact handheld vacuums to powerful stick vacuums with a turbo mode. In every review we do a test of strength. We do this in the same way in every review (with a custom-made vacuum tester) to be able to compare the vacuum cleaners with each other.

Best Powerful Bagless Vacuum Cleaner

The Miele Boost CX1 Parquet is the most powerful bagged vacuum cleaner at the moment. The vacuum cleaner has a suction power of no less than 21 kPa, which is very strong compared to other vacuum cleaners.

In terms of air speed, this Miele vacuum cleaner also scores well: in my review I measured an AirFlow of 41.8 meters per second. In addition, you also enjoy the following benefits with this vacuum cleaner:

  • The vacuum cleaner is super manoeuvrable thanks to the TrackDrive technology
  • The dust container is super easy to empty
  • He looks so beautiful

The vacuum cleaner, on the other hand, has a very short cord of only 7 meters. It is also not a silent vacuum cleaner: with a noise level of 70.8 decibels, it is quite noisy. Curious about more features of this vacuum cleaner? Watch the video below, where I extensively review the Boost CX1 Parquet.

Best powerful stick vacuum cleaner

At the moment, the Dyson V15 scores best in terms of suction power: in my Dyson V15 Detect review, this stick vacuum came out with a suction power of 10 kPa, which is a lot higher than other stick vacuums.

The Dyson V15 Detect also has a turbo mode: with this there is even a suction power of 27 kPa, but in this mode you can only use the stick vacuum for a few minutes. The Dyson V15 has the following benefits:

  • Fluffy brush with laser, making dirt more visible
  • Piezo sensor adjusts suction power automatically

The vacuum cleaner does have a high price: you pay for the extra options and accessories.

Best Powerful Handheld Vacuum Cleaner

Prefer a compact handheld vacuum cleaner? Then go for the Turbotronic LUX400: a hand-held vacuum cleaner with a suction power of 8 kPa. This means that the suction power is even close to that of a stick vacuum.

Turbotronic Lux400

With this powerful hand vacuum cleaner you can not only vacuum dry, but also wet dirt.

The Turbotronic LUX400 is not only very powerful: it is also a lightweight vacuum (it weighs only 0.5 kilograms). You also enjoy the following extras:

  • Comes with many accessories, including a flexible hose
  • Has a respectable battery life of 19 minutes

Keep in mind that this vacuum cleaner makes a lot of noise. In addition, it is of course a hand vacuum cleaner: you will have to empty it quickly and the battery lasts much shorter than cordless stick vacuums.

How I research the power of a vacuum cleaner

In all my vacuum cleaner reviews, the suction power is perhaps one of the most important research factors. I usually can’t wait to put my custom vacuum tester on the vacuum cleaner when a new model comes out.

With my vacuum tester I can measure the suction power of the vacuum cleaner in Kilopascals. I can then compare the vacuum cleaners with the number of kilopascals, to find out which vacuum cleaner is the strongest.

In all my vacuum cleaner reviews, the suction power is perhaps one of the most important research factors.

To ensure a fair suction power measurement, I always adhere to the following research rules:

  • The vacuum cleaner is emptied beforehand
  • The vacuum cleaner is checked for possible air leaks
  • The power of the vacuum cleaner is set to maximum*

* Stick vacuums and handheld vacuums sometimes also have a turbo mode. We are this mode as an ‘extra option’. Because you can only vacuum for a few minutes with a turbo mode, we only compare the suction power in normal mode.

Why a research into the most powerful vacuum cleaner?

The more power a vacuum cleaner, the more power it has. However? No, unfortunately this is not the case. In the past people often looked at the power (in the number of Watts), but nowadays this does not say much about the suction power.

In the past people often looked at the power (in the number of Watts), but nowadays this does not say much about the suction power.

Reason enough for me to do good research into this, so that I can help you choose the most powerful vacuum cleaner. But, why is a powerful vacuum cleaner so important? A powerful vacuum cleaner is interesting for the following situations:

  • When you often have carpet or rugs in the house
  • If you are prone to an allergic reaction*
  • When you have pets and have a lot to do with pet hair

* In addition to good suction power, it is also important to pay attention to the filters of the vacuum cleaner. A high suction power says nothing about the filters of a vacuum cleaner. Read more about the HEPA filter and why it is so important here.

Various powerful vacuum cleaners

The type of vacuum cleaner often determines the suction power. For example, a hand vacuum cleaner is in many cases much less powerful than a canister vacuum cleaner. In general, a cordless vacuum cleaner is much less powerful than a corded vacuum cleaner.

There is also a big difference between a bagless vs bagged vacuum. The suction power of a vacuum cleaner with a bag can decrease sharply when the dust bag becomes full. This is not the case with a bagless vacuum cleaner.

Maintenance of great impact on vacuum cleaner power

The power of a vacuum cleaner often also depends on how you maintain your vacuum cleaner. A vacuum cleaner that no longer sucks or whose suction power has decreased significantly is often the result of a blockage. It can also be a dirty or outdated filter: a HEPA filter replacement can already help to improve the suction power.

In summary: the higher the suction power, the easier it is to vacuum dirt. In order to discover the most powerful vacuum cleaner, I measure all my reviews the suction power in kilopascals.
