The invention of the vacuum cleaner has simplified our lives and increased our productivity. However, it can be difficult to justify the cost of purchasing a high-quality vacuum cleaner, and some people may even make the mistake of doing so.

What are the qualities of a good vacuum? In other words, how detailed need a vacuum's specifications be? A good vacuum cleaner has how many watts? There are probably a lot of questions like these running through your head, and that's why we're here to help.

A quality vacuum cleaner is the subject of this article.

Learning About The Fundamentals Of Vacuum Cleaners

Investing in a handheld vacuum cleaner is a big deal, so make sure you get the one that best suits your needs by familiarizing yourself with its most fundamental features. Here, we'll break down every one of the technical specs that go to determining its overall quality and performance so you can make an informed decision.


Airflow is a powerful indicator of the air's velocity from the floor to the vacuum's bag, and is therefore one of the most important metrics. A minute's worth of breathing air intake is the determining factor. A vacuum's airflow is reported in cubic feet per minute. Although airflow is widely recognized as an important metric, more than half of vacuum cleaner manufacturers fail to include it in their product descriptions. This parameter sets the limits on both the exhaust's resistance and the motor's output. The CFM value is the maximum suction power that can be achieved. Normal vacuum cleaner performance ranges from 50 to 100 CFM.

Air Power

Air watts, like cubic feet per minute (CFM), are used to quantify suction force. Watts of air is how many Watts of power the vacuum cleaner has used to pull air via its hose. Commonly, the nozzle of the vacuum itself serves as the entryway. Using the following formula, you can reliably calculate air watts.

The formula for calculating air watts is as follows: air watts = 0.117254 times airflow (CFM) x water lift.

It is common knowledge that a good upright vacuum cleaner requires at least 100 Air Watts and a canister vacuum cleaner requires at least 220 Air Watts to function effectively. More Air Watts are required by canister vacuum cleaners since they must also pull the dirt and dust.

More AW is required for any vacuum that features a filter that actually works. This is because efficient vacuum cleaners actually pull the air through the filter's fibers.

Water lifts

The vacuum's suction force can also be examined with a water lift. A tube is shut off from the unit and linked to it for testing. The higher the water in this tube is pumped, the stronger the suction.


Manufacturers often list the vacuum cleaner's power consumption in watts. The term "watts" is only used to describe the amount of energy required to operate the vacuum motor and has no bearing on the product's effectiveness.

Simply, the more watts a vacuum cleaner has, the more efficient and strong its motor will be, and the better it will suction. There are many ongoing discussions since this is not always the case.


Amps have the same technical parameters as Watts. Vacuums use a lot of electricity, measured in amps. As a result, the efficiency and quality of the vacuum's suction power increase as the Amps increase.

However, producers typically list the total Amp rating. The Amp rating so incorporates not just the motor, but also the LED lights and brush roll.

Twelve amperes is the maximum allowed for any single appliance. If a device's total amperage is 12, but the head nozzle consumes 1.5 A and the LED lights utilize 0.5 A, the motor only has to produce 10.5 A to run.

Vacuum power and its constituents

We need to analyze the many factors that go into the watt rating of the vacuum. We'll focus on canisters because they're the most popular kind of vacuums. The vacuum's motor-fan is the initial customizable component.

The next part is the engine. The motor spins at a high RPM, the exact value of which varies across different makes and models. Thus, an air current is formed that swiftly empties the vacuum's base. The trash, dust, grime, and other particles at the front base are sucked up by the vacuum. Last but not least, HEPA, a type of filter, is used to clean the air. The trash can is emptied at last. In light of these considerations, it is evident that knowing your vacuum's wattage is vital.

The term "high suction power" refers to what?

There are a number of people who are unable to distinguish between high and low suction units. Putting your mini hand vacuum cleaner on carpet mode is the best way to gauge its suction strength. After the change has been made, the machine can be turned on and let to run at full speed.

Now, you can test the suction power of your vacuum by mounting the floorhead on the wall. A vacuum with sufficient suction power will adhere to the wall without the need for any additional fixings.


In this article, we covered a wide range of topics, including the meaning of vacuum cleaner specifications like amperage, wattage, airflow, and suction power, and how to choose the best vacuum for your needs. Buying a mini handheld vacuum cordless is an investment, so it's important to carefully analyze all of these factors beforehand to avoid wasting money on a model that doesn't meet your needs.
