We take a look at all styles and sizes of vacuums right here at CNET. From light-weight cordless alternatives to more and more superior robot vacuums, we have put a whole bunch of fashions throughout each class by way of their paces. Our cordless vacuum testing takes place on the CNET take a look at lab in Louisville, Kentucky. Every cordless vacuum goes by way of a gamut of assessments throughout completely different flooring varieties, together with evaluations of options, battery life and total usability. Right here’s how we do it.
How we take a look at cordless vacuum cleaners at CNET
All of the vacuums on CNET’s finest lists are examined and evaluated in our state-of-the-art take a look at labs. CNET Testing Labs transcend product specs to check in real-world situations with real-life messes. Through the years, our consultants have examined 50 cordless vacuums and counting.
Here is a breakdown of how we measure cordless stick vacuum performance.
We take a look at the vacuums on each hardwood and two diffrent varieties of carpet.
Cordless vacuum scoring methodology
The principle take a look at we use on all vacuums is a straight-line take a look at throughout completely different flooring varieties (hardwood flooring, low-pile carpet and midpile carpet). The take a look at entails vacuuming at an ordinary suction stage, together with calculations to make sure it’s truthful for all of the fashions that move by way of our lab.
Our course of is intently aligned with the usual established by the International Electrotechnical Commission. The purpose of a straight-line take a look at is to measure what share of filth the vacuum is able to choosing up. We use play sand and pet hair as our major take a look at supplies, together with our mud space adjuster to measure how a lot we disperse on the ground.

Awarding the best performers
The Eureka ReactiSense 440 prices simply $180 however provides the very best efficiency we have seen in a cordless vacuum.
After working all of the assessments beneath, we award the very best cordless vacuums an Editors’ Selection or a lab award within the class the place they excel. Most not too long ago, the Eureka ReactiSense 440 earns our lab award for the very best suction on carpet at 98.53% sand pickup from low-pile carpet and 92.16% from midpile carpet. It additionally earns an Editors’ Selection award for its unbeatable worth as our greatest total cordless vacuum. Equally, the Dreame Z30 earns not one, however two separate lab awards; it excels in a number of classes throughout our lab testing. It takes each our lab award for the longest battery life at 110 minutes and the best suction rating on hardwood at 98.77%.
Inside CNET’s Testing Labs: How we take a look at cordless vacuums and why the sand scores matter
Our workforce of consultants and engineers makes use of play sand to imitate filth and dirt. Every vacuum is examined on a low-pile carpet, midpile carpet and a tough floor with play sand. This take a look at reveals precisely how a lot bodily particles a vacuum is ready to decide up off the ground.
Sand pickup
Our rig to distribute soil throughout the take a look at mattress.
Utilizing the mud space adjuster (what we use to disperse sand or pet hair onto the ground), we subtract one inch from the measured nozzle width to offer the stick vacuum ample protection and alternative to choose up all particles on the carpet or hardwood. We use completely different nozzle widths and quantities of particles primarily based on the ground pattern measurement and sq. footage.
Throughout testing, we set controls to make sure every vacuum undergoes the identical take a look at. For instance, every vacuum is about to the identical nozzle width, and we measure and lay down the very same quantity of particles every time.
We take a look at on each low-pile and midpile carpet to see how properly cordless vacuums are capable of take away sand from them.
At minimal, we conduct three cleansing runs on every ground kind. We rerun take a look at cycles if there’s an apparent outlier among the many three assessments, equivalent to one consequence that is a lot larger or decrease in pickup share. We additionally conduct separate cleansing assessments with pet hair (acquired from a close-by groomer) on every floor kind, photographing and visually evaluating how a lot pet hair, if any, stays after working the vacuum over it.
We weigh the dustbin earlier than and after every run. From there, we are able to calculate the proportion of particles pickup for each cleansing run and the common quantity of soil a vacuum manages to take away.
Pet hair
We measure a exact quantity of pet hair to guage pickup efficiency, however use before-and-after visuals to evaluate outcomes as a substitute of weighing the dustbin.
Our pet hair take a look at is the best. We use 2 grams of pet hair sourced from an area groomer, unfold throughout every take a look at mattress, and take before-and-after images for visible comparability.
For pet hair, we do not weight the pet hair after the take a look at; we use earlier than and after footage of the cleansing run to subjectively consider the effectiveness of the cordless vacuum at choosing up pet hair.
Cordless vacuum battery life and working time
We take a look at battery life by working the vacuum on customary suction till it is drained.
To check battery life, we absolutely cost the vacuum battery, then run it on the medium setting till it drains, avoiding Max or Eco modes. We repeat the take a look at thrice and common the outcomes. The longer the period, the higher the rating. A lot of the vacuums on our record have a battery lifetime of 25 to 40 minutes earlier than needing one other cost, though many fashions are beginning to supply higher-capacity batteries with working occasions of 60 minutes per cost.
A number of of the vacuums we have examined can do even higher, together with the Shark Stratos (80 minutes) and Dreame Z30 (110 minutes). In fact, needing greater than 40 minutes for a single vacuuming session is uncommon, and the prevalence of charging docks makes it simple to recharge between cleansing runs.
With its 110 minutes examined cleansing time, the Dreame Z30 is a superb choice for big properties.
Most cordless vacuums we suggest now function replaceable batteries, so you should buy an additional when you want extra runtime or are involved about battery degradation over time.
A number of of the graphs beneath present the relationships we found in our research between battery life and suction, battery life and worth and battery life and weight. A recent lab data study revealed that almost all cordless vacuums with stronger suction energy even have a shorter battery life. Even so, you do not want to spend so much to get a high-performing vacuum.
Cordless vacuum warranties
Utilizing the Shark Stratos within the take a look at lab on hardwood flooring gave us spectacular scores for sand pickup.
Cordless vacuum warranties range by producer and mannequin, however the majority of fashions we have examined supply at the least a yr of protection, and plenty of supply two years. The perfect guarantee we’ve seen comes from SharkNinja, which provides a five-year restricted guarantee on its cordless vacuums. An extended guarantee interval is sweet as a result of it means your vacuum is roofed if an element breaks or one thing is flawed.
Filters and air high quality
Most cordless vacuums have a filter that stops mud from being blown again into the room when you’re vacuuming. A lot of the finest cordless vacuums include replaceable HEPA filters (generally present in air purifiers) that may filter particles as small as 0.3 microns, whereas cheaper fashions could have a extra fundamental fabric filter. One latest innovation we’re seeing from SharkNinja is the incorporation of an anti-allergy seal and anti-odor capsules that assist preserve your vacuum and dustbin from growing odors, although this requires odor-releasing pods that add further price.
Consumer expertise (ease of use and luxury)
The Aero base station fees the vacuum and self-empties it right into a 3.5-liter mud bag.
Whereas it’s not a major issue, the convenience and luxury of utilizing a cordless vacuum and emptying its dustbin nonetheless play a job. We contemplate this a part of the general consumer expertise. We like cordless vacuums that may stand upright on their very own and fashions with charging docks or self-emptying options, since each scale back the quantity of upkeep required. Robust bonus factors go to a vacuum docking station that empties mud into a bag rather than a bagless dust canister as a result of it signifies that mud is much less prone to get throughout your newly vacuumed flooring whenever you empty it into the trash.
What about handheld vacuums?
I obtained the vacuums on this take a look at by way of retail purchases and producer samples.
Most, if not all, of the cordless vacuums on this record could be damaged down into handheld models, making them appropriate for cleansing your automobile or upholstery. Nevertheless, we use a barely completely different testing methodology for handheld vacuums, so we suggest checking our not too long ago up to date record of the best handheld vacuums to see our suggestions to be used circumstances starting from cleansing automobiles to pet hair. Plus, many handheld vacuums weigh as little as 1.2 kilos, placing them in a unique weight class from these cordless vacuums.
Different options
The Shark Stratos has helpful LED headlights to assist it discover mud.
As new cordless stick vacuum fashions emerge, we’re seeing the flexibility to detect filth varieties and ground varieties and alter suction energy accordingly. “Because of this when a considerable amount of filth is detected, suction will increase and when much less filth is current, suction decreases,” says CNET’s lab engineer Gianmarco Chumbe. Chumbe, who’s been testing dwelling tech merchandise at CNET labs for eight years, says the most recent vacuum tech can sense ground kind and alter suction energy accordingly. “The principle good thing about this function is elevated battery effectivity, leading to a more practical and longer-lasting cleansing expertise.”
Shoppers purchasing for vacuums at this time, Chumbe says, ought to contemplate the cost-to-value ratio. “Ask your self, does the worth justify the efficiency, options and luxury it provides?” CNET writers and editors use worth and worth in our vacuum scoring exactly because of this.
Cordless vacuum weight, measurement and bin capability
The PencilVac rollers are designed to eject hair to keep away from tangling.
A lot of the cordless vacuums we examined weigh between 4 and eight kilos. When a vacuum weighs 10 kilos or extra, we contemplate it unwieldy. A lot of the vacuums on this record have been additionally very related in peak and total measurement. In addition they include equipment that may be hooked up and indifferent to offer you versatile cleansing choices. As an example, a standard device is a crevice-cleaning attachment that permits you to match the vacuum nozzle into tight areas and corners the place a bigger brush head cannot attain.
For the dustbin measurement, we contemplate something of 0.6 liters or larger to be good. Typically, something lower than 0.5 liters would require you to empty it after each cleansing session. A big dustbin means you possibly can go longer with out emptying. Nevertheless, if the cordless vacuum comes with a self-emptying charging dock, it may typically retailer mud and particles for 30 days or extra, minimizing the quantity of mud you are confronted with when vacuuming.
