What Is The Best Suction Power For A Vacuum Cleaner?

When it comes to what is the best suction power for a vacuum cleaner, there are many factors to consider. Different models have different strengths and weaknesses, so it’s important to find the one that fits your specific needs. Some people might prefer a model with more powerful suction, while others might prefer one that is quieter or easier to maneuver. In this blog post, we will discuss the different factors you should consider when choosing a vacuum cleaner with strong suction power.

A vacuum cleaner is a device that relies on suction power to get rid of dust and debris from floors, upholstery, and other surfaces of your home. The suction power of a vacuum cleaner is usually measured in watts or amps.

The higher the suction power, the more efficiently it can remove dirt and debris. In fact, a machine with more suction power provides a better performance level and cleans your home more efficiently.

If you are in the market for a new vacuum cleaner and wonder what is the most powerful available, you have come to the right place.

Is the Suction Power Higher, the Vacuum Better?

First, let’s talk about how suction works. A vacuum cleaner sucks up dirt and debris from your floors using a powerful motor-driven fan. The fan forces air into the cleaner, which in turn creates a vacuum. That vacuum is what pulls dirt and debris into the machine.

So, does that mean that a higher suction power means a better vacuum? Not necessarily. The truth is, suction power is just one of many factors that you need to consider when shopping for a new vacuum. Other important factors include weight, noise level, bag size, cord length, and attachments.

For example, if you have a lot of hardwood floors in your house, you might want to consider a vacuum with strong suction power but relatively weak brushes. On the other hand, if you have mostly carpeted floors, you’ll want to focus on finding a unit with powerful brushes but moderate suction.

However, when you only consider suction power, more is usually better. A higher wattage vacuum cleaner can suck up most of the dust and debris from home surfaces compared to models with lesser suction power.

How To Measure The Sucking Ability Of A Vacuum Cleaner?

What Is The Best Suction Power For A Vacuum Cleaner

There are two main ways to measure the suction of a vacuum cleaner. Utilizing Air Watts or CFM (Cubic Feet Per Minute) also known as airflow. Here at the Wright Vacuum Company, we prefer using Air Watts because it is the most accurate method of measurement.

What is Air Watts?

Air Watts measures the power of a vacuum by taking into account both the airflow and the amount of suction. The formula for this looks like this AIR WATTS = Suction (in inches of water) x Airflow (in cubic feet per minute). To put it simply, the higher the number of air watts, the more powerful the vacuum.

For example, the Dyson Ball Animal 2 has an airflow rating of 35 liters per second and a suction rating of 250mmH2O. This calculates to an impressive total of 91.67 AW.

The Shark Rotator Lift-Away TruePet NV752 has an airflow rating of 45.2 CFM and a suction rating of 220 in/H2O which calculates to 100 AW – just beating out the Dyson Ball Animal 2. However, this isn’t always the case as you will see with our next example.

The Hoover Linx Signature Cordless Stick Vacuum comes in at 20 volts with 108 inches of suction power per hour which only calculates to 24 AW. So although it’s not as high as some other vacuums on this list, it doesn’t mean that it can’t do a good job at cleaning your floors – it’s all about finding the right vacuum for your needs.

What is CFM?

CFM or Cubic Feet per Minute is a measure of how much air a vacuum cleaner can move in one minute. The higher the CFM number, the more powerful the vacuum.

For example, the Dyson Ball Animal 2 has an airflow rating of 35 liters per second which converts to 949 CFM and a suction rating of 250mmH2O which converts to 91 kPa or 13 psi – giving it a total output power of 91 AW.

As you can see from our examples, just because a vacuum has a high CFM number doesn’t necessarily mean that it will have a high output power when measured in AW. This is why we believe that Air Watts is a more accurate measure of suction power.

What Is The Highest Suction Power Of A Vacuum Cleaner?

The highest suction power you can find in a vacuum cleaner ranges between 400 and 1000 Watts. Some models even go up to 1200 Watts. However, what makes the most sense is to select one that matches your household cleaning needs.

For example, if you have a large house with high-pile carpets and hardwood floors, you should invest in a powerhouse of a vacuum cleaner that offers more than 1,000 Watts. On the other hand, if you have mostly tile and low-pile carpets, a model with 400 Watts or less might be enough.

What Is The Best Suction Power For A Vacuum Cleaner for Your Home

  • Upright – 1200 Watts
  • Cordless – 150-200 Watts
  • Canister – 1200 Watts
  • Commercial -1500

Upright – 1200 Watts

An upright vacuum is a great option for homes with hardwood floors or low-pile carpets.

The suction power on an upright is typically around 1200 watts, which is more than enough to get the job done.

Plus, upright vacuums are usually relatively quiet, so you won’t have to worry about disturbing your neighbors while you’re vacuuming.

Cordless – 150-200 Watts

A cordless vacuum is a great choice if you’re short on storage space or if you have allergies and need to be able to vacuum quickly and easily.

Most cordless vacuums have a suction power of between 150 and 200 watts, which is plenty for most homes.

The only downside to a cordless vacuum is that they typically don’t have as much suction power as an upright or canister vacuum.

Canister – 1200 Watts

A canister vacuum is a good choice for homes with a mix of hardwood floors and carpets. The suction power on a canister vacuum is usually around 1200 watts, which is more than enough to get the job done.

One thing to keep in mind with a canister vacuum, however, is that they can be notoriously difficult to maneuver, so if you have back problems or are short on storage space, this might not be the best option for you.

Commercial -1500Watts & Up

If you have a lot of floors or a lot of carpeting in your home, then you might want to consider a commercial vacuum.

Commercial vacuums typically have a suction power of 1500 watts or more, so they’ll definitely get the job done.

However, they are also very large and heavy, so they can be difficult to maneuver and store. Plus, they tend to be quite loud, so if you have sensitive hearing or live in an apartment complex, this might not be the best option for you.

Does Higher Wattage Mean More Efficiency?

Yes. A higher-wattage vacuum cleaner means better efficiency when it comes to performance. This is because the more powerful suction ensures that all the dust and dirt are completely sucked out of your carpet while also providing a deeper clean.

Moreover, vacuums with high wattage use less energy compared to those with lower wattage, so you can save money in the long run.


Choosing the best vacuum suction power for your home depends on several factors: what type of floors you have, how much storage space you have, and whether or not you have allergies. If you’re still not sure which one is right for you, we recommend consulting with a professional before making your final decision.
