How Many Watts Is a Good Vacuum Cleaner?[fully Guide]

A vacuum cleaner is a device that is used to remove dirt, dust, and other small particles from surfaces.

The amount of power a vacuum cleaner has should be proportional to the size of the surface it is expected to clean. It should also be proportional to the type of surface that needs cleaning. For example, carpets require more suction power than hardwood floors.

There are two main types of vacuum cleaners: upright and canister. Upright vacuums are generally more powerful than canister vacuums because they have a larger motor and can handle more debris at once. However, upright vacuums are bulkier and heavier than canister models, which makes them less convenient for use in smaller spaces or on stairs.

But what can be a proper vacuum cleaner for you? How many watts is a good vacuum cleaner? Have you ever asked yourself these questions? Whether you did or didn’t, this article will give you all the answers related to the questions.

Answer To How Many Watts Is A Good Vacuum Cleaner

It’s important to consider the wattage when buying a vacuum cleaner. The higher the number, the more powerful it is for cleaning.

Watts That A Good Vacuum Cleaner Uses

Before knowing how many watts a good vacuum cleaner uses, we feel responsible for notifying you of its general specifications. Remember we introduced some specific terms to consider at the beginning?

Watts That A Good Vacuum Cleaner Uses

AIr flow (CFM)

This parameter shows the airflow’s power from the ground surface into the vacuum cleaner. In detailed terms, it measures the amount of air sucked within a minute into the vacuum cleaner. 

The unit of airflow is given in cubic feet per minute. Despite being a crucial parameter in determining the performance of the vacuum cleaner, more than half of the time manufacturers do not specify the CFM of their products.

Air watts (AW)

This parameter measures the amount of power consumed due to a unit’s worth of air intake into the vacuum cleaner’s opening. 

To be considered “good”, a typical vacuum cleaner needs to have at least 100 AWs, and for a canister vacuum cleaner, the value is more than double, at 220 AWs.

Water Lift

Just like CFM, a water lift enumerates the suction power of the vacuum cleaner when it is “sealed”. A better way to picture it would be when the vacuum cleaner is sucking in water, in which case there is no airflow and the column is completely filled with water. 

Water lift measures the height that the water being sucked into the cleaner rises, hence giving an indication of the suction power. 

This is important to know as it evaluates the power with which the vacuum cleaner lifts up debris off of the surface while the airflow carries the debris into the dirtbag.


Watts refers to the efficiency of the motor of the vacuum cleaner, as is the most commonly quoted information you would find on almost all vacuum cleaners. 

Arguably, the greater the watt of a vacuum cleaner, the more powerful the motor would be and so greater the suction power. 

However, this argument is heavily debated and the power of a vacuum cleaner may not be accurately determined simply by its watt rating.


Amps is a measure of current drawn in by the cleaner. Similar to watt, greater amps would indicate greater efficiency and suction power of the vacuum cleaner. 

However, keep in mind that manufacturers quote the amperage of a vacuum cleaner as a whole, meaning they include the total current drawn in by all the components in the cleaner. Only a part of the quoted amp value is consumed by the motor.

Now we can come back to our question- how many watts is a good vacuum cleaner? Typically all vacuum cleaners work with energy from 500 to 3000 watts. 

Meanwhile, some research shows that a good quality vacuum cleaner uses approximately 1400 watts of energy.

First of all, we will sort out how many watts a good vacuum cleaner uses according to its type. However, using the watt amount depends on what types of vacuum cleaner you are using and what purpose. Besides, a lot of things are related to it.

Suction Power

Suction is the power that speeds up the airflow. It means that the airflow can move fast with high suction power. Many artisans measure this suction with a torr unit.

Now we can come back to our question- how many watts is a good vacuum cleaner? Typically all vacuum cleaners work with energy from 500 to 3000 watts. Meanwhile, some research shows that a good quality vacuum cleaner uses approximately 1400 watts of energy.

First of all, we will sort out how many watts a good vacuum cleaner uses according to its type. However, using the watt amount depends on what types of vacuum cleaner you are using and what purpose. Besides, a lot of things are related to it.

Handheld Vacuum Cleaner

A handheld vacuum cleaner is a handy one for cars and small spaces. It is portable and small in size. Moreover, it can clean dirt from the tiniest area, which a giant vacuum cleaner cannot do.

A good-quality handheld vacuum cleaner uses only 200 watts of energy. In addition, 10-volt suction power is enough for it. You have to look for a handheld vacuum cleaner with a minimum of 15 air watts and a 16-volt battery if you want a good one.

Canister Vacuum Cleaner

If you need a vacuum cleaner for a bigger space like an office or hospital, you can try a canister vacuum cleaner. It comes with a big-wheeled body and dust container attached with a vacuum wand. Moreover, it is lightweight, and you only have to do more around the wand.

The canister vacuum cleaners provide more suction power and airflow than handheld vacuum cleaners. That means it also needs more vacuum watts. The canister vacuum cleaners generally use power between 1200 and 2000 watts.

Upright Vacuum Cleaner

An upright vacuum cleaner is upright at stand-up, just like its name. It works as an all-in-one solution. But this vacuum cleaner is the best for cleaning carpets and floors. Moreover, it comes with both bagged and bagless systems.

Most upright vacuum cleaners use from 500 to 1400 watts of power. So, a 10 Amp upright vacuum cleaner is pretty enough for your home-vacuuming. 

Autonomous or Robot Vacuum Cleaner

Do you want to find a cheap vacuum cleaner in the market? An autonomous or robot vacuum cleaner not only provides low-cost maintenance but also gives your home a robotic vibe.

The power a robot vacuum cleaner uses is pretty low. The average power consumption is between 30 and 90 watts. Typically it works for a maximum of 60 minutes in normal mode and 90 minutes in eco mode. However, its suction power is not so high. This vacuum cleaner consumes only 3.6 kWh in a month.

Does Higher Wattage Of A Vacuum Cleaner Mean Better Suction?

The higher wattage of a vacuum cleaner does not necessarily mean that it will provide more suction. The suction power is essential for a vacuum cleaner since it directly affects the vacuum cleaner’s performance. On the other hand, the wattage is only a total power measurement.

You can relate the wattage to the electricity consumption. For instance, using 3000 watts of power in a week means that you consume 3 kWh of electricity per week (1k watt=1 kilowatt). It is a straightforward calculation.

So, if you can use more electricity, you can go for a vacuum cleaner with higher wattage. However, it does not talk about suction. So, higher wattage or amps does not indicate the higher power of a vacuum cleaner.

How To Calculate Electricity Consumption Using Wattage?

Indeed, very few people calculate the yearly electricity consumption of their vacuum cleaners. Some people may find it unnecessary. However, we find it necessary to calculate the electricity bill of vacuum cleaners if you are not filthy rich!

Computing electricity consumption is much easier than you ever think. We will show you the calculation using the Watt.

Suppose you use a regular vacuum cleaner for 2 hours or two days a week, which means 94 days or hours in a year. Your vacuum cleaner contains 500 watts of power.

You have to keep in mind that 1000 Watt = 1 kiloWatt.

So, your yearly energy consumption is 1 hour*94 days*(500Watts/1000) = 48 kWh.

The equation boils down to:

Energy consumed (kWh) = hours x days x power consumption (in kW)

You can easily do this calculation to consider your monthly or yearly vacuum cleaning cost. That will also help you select the proper vacuum cleaning according to your financial need.

How To Spend Less Electricity With A Vacuum Cleaning?

You already have the answer to the question- how many watts is a good vacuum cleaner? However, more wattage means more electricity. Electricity bill is now one of the most significant facts as we depend on it.

How To Spend Less Electricity With A Vacuum Cleaning

If you have some issue like this, you can try some tricks with your vacuum cleaning to consume less electricity. It sounds crazy. But it is possible.

Check out some simple tips below to use less electricity with a vacuum cleaner-

  •  Look for a vacuum cleaner for a specific purpose. Consider what purpose you need a vacuum cleaner most. Thus you can save electricity with an energy-efficient vacuum cleaner.
  • If you have the habit of cleaning with a vacuum cleaner now and then, wipe it out from your head. Try not to use a vacuum cleaner for a simple reason. Try and restrict your use of vacuum cleaners for heavy-duty purposes, like an overall cleanup of the house.
  • Try not to make your floor dirty as much as possible. For example, do not bring your shoes inside the room.


Is a higher wattage vacuum cleaner better?

As explained earlier, higher power consumption of the motor may logically seem to indicate greater suction power and hence better cleaning. Well, this line of reasoning is not widely accepted as other contributing factors also come into play.

What type of vacuum cleaner would be the best for me?

For small homes and spaces: use a handheld variant. Then for the larger office and apartment home spaces: use a canister vacuum cleaner.

For domestic heavy use purposes and ease of use: consider an upright cleaner
And if you do not feel like tediously going around the house cleaning every part of it: purchase an autonomous cleaner.

BUT REMEMBER! Please do not use vacuum cleaners too often, as there is a factor of cost and electricity consumption that you must be taking serious into account.

Final Verdict

Wattage is one of the essential matters if you have an electrical issue. To sum up, undoubtedly, a vacuum cleaner makes cleaning easier. However, it would help to consider some facts before getting a vacuum cleaner.

In addition, the wattage of a vacuum cleaner also points out the power and energy efficiency of a vacuum cleaner. With this in mind, this article will help you find out how many watts is a good vacuum cleaner.
