Understanding Suction Power in Vacuum Cleaners

When buying a vacuum cleaner, suction power is one of the most important things to think about.

It means a vacuum cleaner’s ability to pick up dirt and other things from surfaces.

Suction power can be measured in different ways, such as by airflow (CFM), air watts (AW), water lift (inches of H20), amps, and horsepower.

Water Lift or Sealed Suction

  • Water lift or sealed suction is a test that determines the suction power of a vacuum cleaner. It involves a tube filled with water placed in a sealed container. In this test, the vacuum cleaner’s suction power is directly proportional to the water lifted in inches of H2O.

Airflow and Air Watts

Airflow, which is measured in cubic feet per minute (CFM), shows how much air the vacuum cleaner can move.

Air watts, which are measured in air watts (AW), show how much power the vacuum cleaner has by adding the suction power and the air volume.

Airflow is the force of the vacuum’s airflow across a surface, which picks up dirt and moves it to the dust bag or container.

Most of the time, the air flow rating is found by measuring how much air goes through the power unit.

Using the formula (Air Flow (in CFM) x Vacuum (in inches of water lift))/8.5 = Air Watts, you can figure out how many watts of air flow you have.

Wattage and Amps

Wattage is another way to measure how much suction power something has.

It shows how much energy is needed for the motor to work.

But wattage does not always mean more suction power because there are other parts in a vacuum cleaner that also use electricity.

Amps measure the amount of electricity going through the machine and can be used to compare the amount of power that each model takes in.

Other Factors Affecting Suction Power

Other things that affect suction power are the type or size of the dust collector, the gaps between the attachments, hose, and brush, and the type of dust reservoir.

A new vacuum might only have half the power of an old one, but it might still be able to pick up as much as the old one.

This is because vacuums get better at using energy without losing their performance.

The suction power of a vacuum cleaner is also affected by the type of dust collector or vacuum cleaner bag and the size of the bag.

When a vacuum bag has an extra filter, it needs more suction power so that air can flow through all of the filters and out of the bag.

Because they have smaller holes, HEPA filters need more power to pull air through them.


When figuring out suction power, it is important not to mix up horsepower with other measurements, as this can be misleading.

Wattage is a common way for manufacturers to describe the power of an electric motor, but it does not always mean that the vacuum cleaner has more suction power because there are other parts that also use power.

Determining the Best Suction Power for Your Needs

Understanding Suction Power

The suction power of a vacuum cleaner is measured in mm water column or Pascal (Pa) at the end of the tube of a complete vacuum cleaner, which includes the tube, hose, and filters but not the nozzle.

The suction motor turns the electricity into suction power, which is measured in watts (W).

Watts, on the other hand, only show how much energy the motor needs.

They do not show how strong the motor is or how well it vacuums.

Amps are a way to measure how much electricity is flowing through your machine.

When you multiply the voltage by the number of amps, you get watts.

In North America, central vacuums are measured by cubic feet per minute (CFM) and water lift.

Air watts are the best way to figure out how well a vacuum system cleans.

By far, the most important thing about a vacuum cleaner’s ability to clean is how well it moves air.

It is important to keep air moving, especially through long pipes and hoses or when using a tool with a small air opening, like a turbine brush vacuum attachment.

Determining Ideal Suction Power

The best suction power for a vacuum depends on the type of vacuum and the surface that needs to be cleaned.

A cordless upright vacuum cleaner should have at least 100 watts of air power to clean a variety of floor surfaces well.

The best Samsung vacuum cleaner has up to 210W of power.

For better efficiency, a canister vacuum cleaner should have 220 AW and an upright vacuum should have 200 AW.

Air wattage needs to be higher in vacuum cleaners with HEPA filters because the air needs to be pulled through tiny holes, which takes more power.

Measuring Suction Power

The sealed suction or water lift test is used to figure out how well a vacuum cleaner can pull in air.

Inches of H2O are used to measure the water lift.

It involves putting a tube full of water in a sealed box.

In this test, the power of the vacuum cleaner to pull in water is directly related to the amount of water.

Airflow is another important feature that helps figure out how well a vacuum can clean.

Wattage is the most common way for manufacturers to say how much power a vacuum cleaner’s electric motor has.

Most people think that a vacuum cleaner with a higher wattage will have a stronger suction, but that is not always the case.

A vacuum cleaner also has a number of other parts that use power.

So a vacuum with 1200 watts may only use 400 watts to pull air in.

Amps refer to the amount of electrical power or current flowing through your machine.

They are not a good way to measure the suction power of your vacuum cleaner.

Reducing Noise Level

How loud a vacuum cleaner is depends on how well it can pull in air.

Some of the noise a vacuum cleaner makes comes from the blower and some from the electric motor.

The hard part about making a vacuum cleaner quieter is that you have to do it without making it less powerful.

In one study, the suction nozzle of a vacuum cleaner was changed to improve its power and reduce noise caused by airflow.

Different parts of a vacuum cleaner, like different suction tips or cleaning heads, can also change how loud it is.

A study made a case for the blower in a vacuum cleaner that gave it a better acoustic covering and slowed down the speed of the air and noise coming out of the exhaust ports.

So, acoustic noise caused by airflow can be cut down by changing suction nozzles or making enclosures for blowers.

HEPA Filtration: The Key to Quiet and Efficient Vacuuming

When it comes to vacuum cleaners, one of the most important features that consumers look for is quiet operation.

However, achieving a low noise level without compromising on performance can be a challenge.

This is where HEPA filtration comes in.

HEPA (High-Efficiency Particulate Air) filters are designed to capture tiny particles such as dust, pollen, and pet dander, which can cause allergies and respiratory problems.

By trapping these particles, HEPA filters not only improve indoor air quality but also prevent them from clogging the vacuum’s motor and reducing its suction power.

This means that vacuum cleaners with HEPA filtration can operate more quietly and efficiently, as the motor doesn’t have to work as hard to maintain suction.

So, if you’re looking for a vacuum cleaner that is both quiet and effective, make sure to choose one with HEPA filtration.

Choosing a Vacuum Cleaner for Power and Quiet Operation

How to Choose a Quiet Vacuum Cleaner

When it comes to vacuum cleaners, it is important to think about how loud they are.

A vacuum cleaner that is too loud can be annoying to you, your family, and even your neighbors.

There are a few ways to make a vacuum cleaner run more quietly, which is good news.

Optimized Bends

Optimized bends in the vacuum cleaner are one way to lower the noise level.

Bends that are not optimized can make more noise and reduce performance.

Most of the time, stick vacuums are quieter and have better bends than other types of vacuums.

They are also a good choice if you do not have much room for storage.

Materials and Components

The way a vacuum cleaner is made and what it is made of can also affect how loud it is.

Because they use better materials and parts, high-end models tend to be quieter because there is less rattling and other noise.

When buying a vacuum cleaner, you should look for ones that are made to run quietly.

Silent Motors and Insulation

Vacuum cleaners with quiet motors and insulation are also quieter than those without these features.

Also, some vacuum cleaners come with HEPA filters that help make the machine quieter while also cleaning the air.

Types of Vacuum Cleaners

Customers can think about a few things to find a vacuum cleaner that is both strong and quiet.

If you have stairs in your home, a canister vacuum is a good choice because it has strong suction and is usually quieter than an upright vacuum.

Stick vacuums are usually quieter than other types of vacuums, but they might not be the best choice for a deep clean.

Robotic vacuums are also quiet and can be set to run even when no one is home.


Attachments are something else to think about when picking out a vacuum cleaner.

Motorized power nozzles can make it easier to clean carpets and rugs, and crevice tools can help get to hard-to-reach places where dust tends to gather.

Customers should also think about the surface(s) they will be vacuuming.

Some vacuums work better on some surfaces than on others.

Noise Level

People should also think about how loud the vacuum cleaner is.

The Eufy BoostIQ RoboVac 11S is one of the quietest robotic vacuums on the market, with a noise level of 55dB.

The Hoover Commercial HushTone 13 is one of the quietest vacuums on the market, with a noise level of 69dB.

It is also one of the most powerful vacuums on the market.

Expert Reviews

Lastly, customers should read reviews from experts and other customers to find a vacuum cleaner that meets their needs.

Many experts say that Miele is the best vacuum brand overall.

Consumer Reports chose the Complete C3 Marin Canister Vacuum Cleaner as the best bagged canister vacuum cleaner.

When choosing a vacuum cleaner, it is important to think about how loud it is as well as other things like type, attachments, and reviews from experts.

By thinking about these things, you can find a vacuum cleaner that is both strong and quiet.

This will make cleaning easier for everyone in your home.

Maintaining Suction Power in Your Vacuum Cleaner

Maintaining Suction Power in Vacuum Cleaners

There are a few things you can do to make sure that your vacuum cleaner keeps sucking well over time.

By doing these things, you can make sure your vacuum cleaner works well and smoothly.

Cleaning the Filters

  • One of the most important steps in maintaining suction power is to clean the filters regularly. Filters can become clogged with dust and allergens, which can cause blockages and reduce suction power. To clean the filters, follow these steps:
  • Remove the filters from the vacuum cleaner.
  • Tap off any loose dirt.
  • Hand wash the filters using just water.
  • Allow the filters to dry completely for 24 hours before re-inserting.

Checking for Blockages

  • Another important step is to check for blockages in the floorhead, wand, hose, and airways. Blockages can occur when dirt and debris become lodged in the pipe. To check for blockages, follow these steps:
  • Shine a torch into the hose or look through the wand to ensure nothing has become lodged in the pipe.
  • Check the floorhead for any blockages.
  • Check the hose and airways for any blockages.

Emptying or Changing the Dust Collection Bag

So that air can move through, you should empty or replace the dust collection bag when it is 70–80% full.

Inspecting the Belt and Attachments

It is also important to check the belt and its attachments regularly.

If there are any worn or broken parts, they should be replaced to get the full suction power back.

Cleaning the Air Intake

For shop vacs in particular, cleaning the dust out of the air intake keeps the air moving and lets the machine work at its best.

Cleaning or Replacing Filters

It is important to clean or replace filters on a regular basis, because dirt and dust can build up and get stuck in the folds and crevices of filters.

Cleaning the Brush

Lastly, customers should flip the brush over and clean it or take out any foreign objects, like hair balls, that are blocking the airflow in the hoses or attachments.

Some brushes come apart so they are easier to clean.

Customers should look in their user manuals to find out how to take parts apart, since each model may have different instructions.

By doing these things, you can make sure your vacuum cleaner keeps its suction power over time, letting you clean in a quiet and effective way.


In the end, a robot vacuum’s quiet operation is a game-changer for people who value peace and quiet in their homes.
