Does a Vacuum Cleaner Use a Lot of Electricity?

(Last Updated On: May 27, 2023)

Does a Vacuum Cleaner Use a Lot of Electricity? Even though the vacuum cleaner is the home appliance that consumes the most power, it’s still used in every house.

Using a vacuum cleaner to accomplish household chores can impact your household’s energy expenses. However, numerous vacuum cleaners consume the same amount of energy.

This is why knowing the vacuum cleaners’ power is crucial before purchasing. This article will discuss this and other vital aspects of management in vacuums.

What Exactly is Suction Power (Air Watts)?

The primary function of the vacuum cleaner is to draw dirt out of the bag, chamber, or fix. To accomplish this, the motor needs the energy to create precise pressure inside and outside.

This is called suction power. Suction power decides how the vacuum gets cleaned and is the primary aspect.

Now that you know the significance of air watts, how do you find the right amount for the perfect cleaning?

It would help if you also had less suction power to remove dirt and greater suction strength for ground that is easy to remove. When selecting a vacuum, consider the areas you’ll be cleaning.

How Is Suction Power Measured?

The suction power is measured using various units: Airflow, called cubic feet per minute (CPM), or the water lift (sealed suction) Air Watts.

We are measuring the airflow (or cubic feet per minute) (CPM).

The Cubic Feet Per Minute measures airflow speed outside the bag or chamber. This characteristic is not often listed when describing the product. However, it’s crucial—t

All suction-related hoses, brushes, and other equipment must be removed to obtain the exact measurement. The suction’s power can be measured using a considerable volume of cubic feet per second.

Most vacuums come with between 50 and 100 CPM. Note that the CPM is reduced when you add the filter along with the hose, filter, and other components. The theory is that a high-quality filter can reduce the CPM by 30%…

How Much Is Air Watts Best For A Vacuum Cleaner?

Vacuums with smaller sizes have lower suction power than bigger ones, so if you want a vacuum for your small office or at home and want moderate intensity, 100 air watts would suffice.

You should buy a larger-powered model if you have a massive warehouse, industrial, or home area. Between 180 to 200 air watts is ideal.

Most manufacturers don’t disclose this in the public domain, so you might be required to conduct tests yourself.

It is crucial to take into consideration the flooring, too. What can be thoroughly cleaned on the floor that is not titled differs from the wooden flooring. Wool carpets need more air watts compared to tiles.

Unlike a traditional upright vacuum, air’s more significant power is essential in a cylinder-shaped vacuum cleaner since the particles will move further into the bag.

A good model will require around 100 air watts. However, the cylinder vacuum will need around 200 watts.

Corded Vacuum Cleaners

The corded vacuum cleaners are usually classified between 2 and 12 Amps which translates to Watts (@120V), meaning it is true that most corded vacuums come with a power rating of 1400-240 Watts.

To determine the power an electric vacuum consumes annually, you must multiply the power rating by the month’s running time measured in hours.

If the typical usage that the equipment is two hours per week (it may be longer, but it’s much less! ), For example, a 1200W (10 Amps) vacuum cleaner is made up of:

(Wh) = (Wh) (Wh) = 2h * 4 Weeks * 1200W = 9.6 kWh/month

An average of 12-15 cents for each kWh could mean that one 200W (10 amps) vacuum cleaner with a typical use of 2 hours could increase the monthly electricity bill to 1.15-1.44 US$, which equals 13.8-17.28 US$ per year!

It’s a low cost to own an improved, safer, more relaxing home to reside in.

Adjustable Suction Strength

Most powerful corded units feature adjustable suction levels, which lets users decrease or increase suction based on the requirements.

There are two types of these kinds of systems:

An air-ventilated system lets users open air valves to regulate the air flowing through the cleaner head of the vacuum.

The amount of air that flows through the vacuum is constant, while the suction engine of the machine remains fully powered throughout the day.

These systems are typically utilized on vacuums with cyclonic air filtration systems that can perform adequately only if there is enough high-speed air.

Allows users to adjust the suction’s power by changing its power. The suction motor’s power can be adjusted.

When suction is decreased, as is motor power and, consequently, its energy consumption, this could result in lower costs for energy.

Personally, it doesn’t matter that the vacuum consumes $1 (or 1.30 USD of energy per month, but it’s beneficial to know the differences between these two methods.

Cordless Vacuum Cleaners

The energy utilized in cordless vacuums can be stored in batteries, which recharge by mains power.

Because the amount of time they work on a single battery is contingent on suction power. Most of them are equipped with an adjustable suction, giving the possibility of having two levels or more.

Most battery-powered devices have 50 to 500+ suction motors rated at Watts. They generally use a standard suction power, allowing for a balanced equilibrium between suction power and the battery’s operating time.

So, the device is powered by 500W and runs at a speed of 300W 2 every week (again, it may be more. However, it will be considerably shorter! ). This means:

E(Wh) equals two h * 4 weeks * 300W equals 2.4 1 kWh per month

Take note of the energy the battery provides for the motor that suctions and another electric and electronic system (if they are) during the process.

To charge your battery depleted through heat (the charger and battery get warmer), other energy losses happen, but this is the most obvious.

While charging the battery, up to a third of the energy may be wasted due to various techniques. Thus:

E(Wh) corresponds to 2.4 Kilowatts /0.66 = 3.6 monthly kWh

If you pay an average price of 12-15 cents per kWh, this is 0.43-0.54 US$ per month or 5.16-6.48 US$ per year.

Robot Vacuum Cleaners

The energy usage of robot vacuums is based on their use. Robot vacuums are designed to be cleaned daily to clean flooring all over.

There are two types of robot vacuums based on the system of navigation they employ:

Robot vacuums use a random cleaning pattern.

Robotic vacuum cleaners are fitted with modern navigation systems and can recharge and resume automatically. Option.

Robot vacuums employ a random design of their cleaning clean until their batteries are exhausted to a level of 10-20 percent.

After that, they cease their cleaning work and return to the dock or charging station to recharge fully. When fully charged, they’re ready for the next task to clean.

To determine the energy consumption of a robot vacuum cleaner, let’s take an average unit that has a 14.4V 2500mAh battery that is depleted to 20% per day for 30 days every month. A charging system does this with an efficiency up to the 66 percent mark.

E(Wh) can be described as 14.4V * 2.5Ah * 0.8 * 30 * 0.66 = ~1.3 monthly kWh

The monthly cost of between 12 and 15 cents per kWh is ~0.16-0.20 US$ per month or ~1.92-2.40 US$ per year in electricity.

Robot vacuums come with a sophisticated navigation system. They are usually set to get cleaned at least once each day.

However, they are typically employed in bigger homes and benefit from Recharge and resume functions.

To find out the energy usage of these robotic vacuum cleaners, We will use an average model equipped with the latest technology for navigation, with a 14.4V 3500mAh battery.

It’s being depleted by 20% after one charge. Then, after Recharge and Resume, however, it decreased to 40 this time.

In addition, the vacuum cleaner is employed each day of the month. It also features an advanced charging system with an energy efficiency of 75 percent.

E(Wh) is 14.4V * 3.5Ah * (0.8 + 0.6) * 30 * 0.75 = ~3.00 in kWh/month

Paying an average of 12-15 cents per kWh amounts to 0.36-0.45 US$ per month or 4.32-5.40 US$ per year.

Conclusion – Does a Vacuum Cleaner Use a Lot of Electricity?

As you can read in this article, A typical vacuum isn’t consumed much energy, but it’s best to have a quality model on hand rather than spending money on an upgrade every few years.

While the motor’s power and performance are significant indicators of whether the vacuum you use is of high quality, they’re not the only indicators of its performance at its job.

A vacuum cleaner might have the most potent motor, but if the vacuum is not well-made, it will not perform properly and could release dust and dirt into the area.
