Vacuum cleaner power consumption and electricity cost

Vacuum cleaners are not the appliances that consumes the most electricity at home.

Still, they are regularly in use so it is worth to find out the electricity usage and the electricity cost of our vacuum cleaners.

How much power and electricity does a vacuum cleaner use

Depending on the model, a vacuum cleaner does use from 400 to 1500 Watts per hour.

The power consumption of your vacuum cleaner should be described on the specification’s label. 

If not, you may do a search on the internet as we are showing on the picture below.

vacuum cleaner power consumption

As an example, our vacuum cleaner does use 620 Watts (W) or 0,62 Kilowatts per hour (kWh). 

620 W / 1000 = 0,62 kW or 0,62 kWh

Because we are paying to our electricity provider 0,217 euro per every kWh we consume, this means that our vacuum cleaner does cost us 0,134 per every hour of usage.

0,62 kWh x 0,217 euro per kWh = 0,134 euro per hour

How to calculate power from voltage and current

If you only know the voltage and current of your vacuum cleaner, you can calculate the power consumption, in Watts, using the calculator below.


For more information about Power, Voltage and Current, scroll down to the ‘Electricity Measurement Units’ section.

Vacuum cleaner electricity cost calculator

Once you know the power consumption, the calculator below can be used to estimate the power consumption and the electricity cost of a vacuum cleaner over a period of time.

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


For example, if your vacuum cleaner:

> It has a power rating of 620 Watts

> You use it for 30 minutes per day and 150 days per year

> You are paying 0,217 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 10 euro (or dollars, or pounds, or…) per year in electricity costs.

How much does electricity cost

If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.

Alternatively, if don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.

Home appliances and devices electricity calculators

A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:

Vacuum cleaner electricity usage monitor

If you want to know the exact electricity usage of a vacuum cleaner, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost. 

Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.

plug in power meter

All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket. 

So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.

Have a look to this YouTube video for more information.

Vacuum cleaner electricity usage FAQ

How many watts does a vacuum cleaner use

Depending on the model, from 400 to 1500 Watts per hour.

If you want to know the power consumption of any specific model, the easiest and quickest way is to search for the specific model specifications on the manufacturer’s website.

Do vacuum cleaners use a lot of electricity

It depends on the wattage and how often and for how long they are used.

A 400 watts vacuum cleaner used for 30 minutes will consume 0.2 kWh.

A 1500 watts vacuum cleaner used for 30 minutes will consume 0.75 kWh.

If you are paying, for example, 20 cents per kWh, 0.2 kWh will cost you 4 cents in electricity and 0.75 kWh will cost you 15 cents in electricity.

You can use the calculator from the ‘Electricity cost calculator’ section to calculate the electricity cost of a vacuum cleaner.

What is a good wattage for a vacuum cleaner

A 600 Watts vacuum cleaner should be enough to vacuum a house or apartment.

Vacuum cleaners and energy conservation

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment 

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

Energy conservation calculator

If we could reduce our vacuum cleaners electricity usage, even a very small amount, it would make a big impact on preserving our natural resources.


For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) on the vacuum cleaners electricity usage, that would add to 32850 Kilowatt hour (kWh) saved per year. 

9000 households x 0,01 kWh per day x 365 days per year 

32,850 kWh saved per year

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro per year.

> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.

Have a look to this page for more information about the amount of resources needed to produce electricity.

In any case it is clear that small energy savings do really count when looking into the bigger picture.
