Energy Guide: What is Sucking Up Your Savings?

Written by: Gautam Sajja

Vacuums! They help clean our carpets, our cars, and anywhere there might be dust or dirt. Welcome to a new installment of Energy Guides where we try to help break down crucial components of common household appliances. My name is Gautam Sajja, and this Energy Guide is all about vacuums.

The vacuum is an essential appliance to home cleaning, but the market may seem crowded with many different designs vying for your purchase. Unfortunately there is no single rating that indicates a vacuums cleanability. However, there are a number of primary vacuum cleaner specifications, that when clearly understood, allow consumers to make educated decisions concerning which vacuum cleaner will have the best cleaning ability.

Although cleanability is what many maybe looking for, in this guide we will be looking at the energy side of vacuums to determine the different types of possible power used by these various models.

Our list will consist of watts, amps, and volts.


Watts is a relatively common unit and an easy way to distinguish the amount of power a vacuum uses. This is because the input power of the vacuum is measured in watts. Although this specification doesn’t take into account the efficiency of the motor, the number of fans or the overall vacuum cleaner design, motor wattage is a valid way to evaluate and compare the power of the motor.


A very common vacuum cleaner specification is amps. The amperage rating designates the maximum amount of electrical current used by all of the vacuum cleaner’s electrical components when operating. The biggest consumer of electrical current will be the vacuum motor, but the amperage rating includes all of the electrical components, including the vacuum motor, the power nozzle motor, the light bulb, etc. This is the closest thing to a baseline for many but not all vacuum cleaners out there.


In the United States, standard household current operates at 120 volts at the meter. Voltage within a home is sometimes referred to as “110” and this is because there may be voltage drops through the house wiring. But not to worry, appliances are designed to operate within a range of voltages from 110 to 120. So a vacuum within these limits will most likely be an efficient one without any problems.

I hope this guide helped you realize some of the lesser to more common ways power is calculated in the vacuum marketing business. There was a lot of information to sift through, so remember that there is still many more types of vacuum specifications out there. The ones covered in this article are simply the units that are commonly associated with energy and power.

Thank you again for reading through today’s guide. It is a pleasure to the entire team to know that someone is making good decisions with the information we provide.

Thank you!
