Your handy household vacuum cleaner may not seem like an energy sucker, but they may use more than you suspect--and there's a wide range of how much power they consume. Some vacuums use .75kWh, while others use just just .2kWh. That's not a ton but, of course, it adds up over time and when considering all the other appliances in your house.

Using a broom and dust mop regularly keeps toxic dust bunnies at bay while burning no electricity, it’s quiet, and can help reduce the number of times per week you need to bust out that vac. Repairing a broken vacuum or shopping for a second-hand one are also eco-friendly options. However, if you’re looking to buy a new eco-friendly model, consider the amount of electricity it uses, its suction power, and its filtration system to make the best choice for your household.

Here are the best energy-efficient vacuum cleaners to consider:

This upright wins for its reasonable price point and versatility. Its 8-foot-long cord and multiple ergonomic attachment tools can sweep upholstery and all of those hard-to-get-reach nooks and crannies. It’s effective on carpets or bare floors.

Use it as a standard upright or sling the detachable canister over your shoulders for the added maneuverability required for cleaning stairs or under chairs. It’s lightweight and ultra-quiet. Its HEPA filter and anti-allergen technology trap dust particles and pet hair. It uses 1200 watts.

Do vacuum cleaners have Energy Star ratings?

At this time, Energy Star does not offer ratings for plug-in vacuum cleaners. In the past, some cordless and handheld vacuums qualified for the Energy Star label thanks to their battery systems, but there are none now available.


Household vacuum cleaners can use anywhere from 500 to 3,000 watts of energy. To find one that hits the sweet spot between efficiency and plenty of suction, we recommend corded vacuums that use between 1200 and 1500 watts. Battery-powered vacuums tend to use very little energy while charging, although batteries may wear out faster that their plug-in counterparts.

TIP:

To reduce your vacuum’s energy footprint there are some simple things you can do. Keep your environment cleaner from the get-go by leaving your shoes — along with the dirt and bacteria like e.coli. that attach to them — at the door. Make sure that the canister or bag is regularly emptied and keep any washable filters clean, so that the suction power doesn't suffer and you can clean in fewer passes.

Final Verdict

Our top pick is the Shark Rotator Professional Vacuum. However, if you’re looking for a cordless handheld model, consider the Black + Decker MAX Flex Cordless Stick Vacuum

What to Look for When Shopping for Vacuums

When choosing an option, consider the following personal and environmental factors. 

What's your style?

Upright vacs are self-contained units that cover a lot of ground easily, making them great for cleaning large areas, carpets, and rugs.

Canister style vacs have the suction power and filtration capability of an upright with increased mobility for cleaning bare floors like tile and hardwood, as well as reaching awkward spaces like staircases.

Stick vacs are upright styles that are compact, lightweight, and great for cleaning and storing in tiny homes and apartments, but they tend to be less powerful.  

Longevity

Choosing a model that’s high quality benefits the environment because it will last longer. In addition, high-end manufacturers—like Dyson—also offer repair and maintenance services that don’t come with cheaper models purchased from superstores.

Amps

Just because a vacuum’s motor has more juice doesn’t mean it’s better at cleaning. Many high-end models have smaller motors (with outputs of 7 amps, for example, instead of 12) but bigger fans and tubing. That means they’re potentially more efficient because you don’t have to run them as long and minimizing carbon emissions.

Bag vs bagless

Vacuum bags can be expensive, need replacing several times a year, and the used ones end up in landfills. It also takes natural resources to produce bags at factories.

Bagless options, however, require more frequent emptying and can be a little messy. Since cleaning them can send contaminants into the air, they may not be a good option for people with breathing conditions like asthma or COPD. For eco-friendlier results, consider one with a washable filter.

The right tools for your floor

Models without brushes are good for tile or hardwoods. Some models might have the option to adjust the height of the brush roll, so it can be used on carpet, rugs, or bare flooring.

Cut the cord?

Not so fast. Cordless vacs are wonderful because they only draw energy during charging. But batteries have to be replaced and discarded eventually, so they’re not always the greenest option. They also can be less powerful so if you have thick rugs or large spaces to clean then they may suck at being the most energy-efficient option.

Filtration matters

One purpose of vacuuming is eliminating dirt from your environment — especially if you have allergies. To improve your indoor air quality, choose a vacuum with a High-Efficiency Particulate Air (HEPA) filter. These filters can capture more than 99.97% percent of particles that are at least 0.3 microns in size and won’t allow the debris to return to the air.

Reduce noise pollution

Let’s face it; vacuums are machines, so they’re loud. If you’re sensitive to sound, look for an option that ideally is runs at 77 decibels or lower. However, not all manufacturers list this information, so you may have a difficult time discovering it.

Got pets?

Consider buying a model with attachments or that are specifically designed “fur” cleaning up after your favorite four-legged family member.

Why Trust Treehugger?

To create this list, we looked for effective vacuums that use fewer watts to operate. We think that bagless options are more eco-friendly than vacuums that require bags that need to be replaced and thrown into landfill. However, if you have underlying health issues, such as asthma, you may need to consider a bagged option for better HEPA control.
