We purchased the 8 most promising cordless shop vacuums available and exhaustively tested them side-by-side in our lab. We evaluated their vacuum power on materials ranging from nuts and bolts to sawdust to puddles of water and more. We weighed them, measured hose lengths, and tested batteries. We scrutinized attachments, measured suction, and evaluated the ease of use. Eventually, we narrowed performance down to four main metrics: dry work, wet work, battery life, and convenience. With this information, we can recommend the best vacuum for your needs.
Not sure what type of vacuum is best for you? We test a wide range of vacuum styles and report on our favorites in each category. From robot vacuums to the top handheld vacuums, each style has perks that make it useful in different scenarios. Need other tools to get the job done? Check out our list of tools on the market.
Editor's Note: We updated our shop vac review on November 26, 2024, to share recommendations for products we like as alternatives to our award winners.
With the suction power to move two gallons of water in just 9 seconds and the airflow to suck up heaps of sawdust, the Craftsman CMCV002B is a true shop vacuum. Though smaller in size, the 2-gallon canister still offers more than enough space for most non-professional applications. The unit runs on a 4 Ah battery (not included), boasting a relatively long 34 minutes of runtime. The hose provides self-retracting elongation from 26 to 94 inches and is crush-resistant due to spring-like coils that lay flat when weighted.
Unfortunately, the exterior design is somewhat problematic. Unlike the toolbox-style models that store hoses, attachments, and batteries internally, the Craftsman attaches all these items to the outside, and the handle sits on the top of the lid, which means you'll have to carve out more storage space for this unit and you likely won't be stacking anything on top of it. However, the standard HEPA filter and the float ball shut-off make this a top-notch machine in the class, and it's our favorite overall. If you'd prefer a model with more convenient storage, we like the Milwaukee M18 0880-20, which features a retractable hose and toolbox-style design.
The Milwaukee M18 0880-20 is a slick little cordless wet dry vacuum. Its two-gallon canister is shaped like a toolbox, with its tube and all attachments stored neatly in the lid. This well-designed machine is a beast at sucking up all types of debris, from nuts and bolts to buckets of water and sawdust. It also features one of the longer tubes of the vacs we tested, and it self-retracts like a spring — long when you need it and short when you don't.
The M18 is a great cordless wet dry vacuum, but it has a few downsides worth mentioning. At just over 10 pounds, it's slightly heavy. Also, it's one of the noisier machines we tested. And despite its five amp-hour battery, a fully charged cell would only power the machine for 23 minutes — not particularly impressive. That said, the conveniences that this model offers overshadow its performance shortfalls. If battery performance is a high priority, perhaps the DeWalt DCV581H is a worthy candidate. Although not an award-winning vacuum in our review, the Dewalt is great if you want to stay within the Dewalt brand and value the need for extended battery life over other areas, such as airflow and suction.
The Ryobi P3240 offers high performance at a reasonable price. It picks up wet and dry materials like a boss. It is also relatively lightweight, and the self-retracting hose and effective attachments store externally on the unit in convenient in-line slots.
While the self-retracting hose design makes for easy storage, it is one of the shortest hoses in our review. The hose diameter also poses some problems when attempting to pick up larger, rigid materials. However, some may see these negatives positively — with the short and narrow hose, there was an improved ability to move smaller heavy objects. Overall, we feel the compact Ryobi will satisfy most people's needs and budgets. For spaces where an extended hose is useful, we recommend checking out the Bosch GAS18V-3. An impressive 72-inch hose length means accessing those hard-to-reach spots becomes more accessible. If storage and vacuum size are not a huge concern, the Bosch is a reasonable alternative.
The economical Kobalt KWDV 0124B-03 is a thoughtfully designed, toolbox-shaped machine. The hose stores in the lid, along with the attachments, making it fuss-free. It includes a HEPA-rated filter, and the hose is among the longest of the models we tested. It's also self-retracting, so you don't pay a storage penalty for the extra reach. Perhaps most importantly, this machine really sucks (in the good sense of the word!) It draws up wet and dry materials like a twister has taken them.
We're not fans of the Kobalt's shorter runtime. Additionally, this model is not the best at pulling liquids off hard surfaces, and its suction rating leaves something to be desired. Nonetheless, this cordless wet dry vacuum performs at a level superior to many of its higher-priced peers, making it well worth the money. If a vacuum centered around performance is what you're after, look to the Craftsman CMCV002B. It provides respectable dry and wet work with a great battery life.
The Ridgid WD0319's large hose diameter makes this model unique and provides both positive and negative attributes, depending on the type of work you're doing. The hose dimensions are great for picking up wet and dry sawdust and accommodating large debris. This machine will be helpful in a shop or for smaller construction jobs.
While the large hose is great for picking up sawdust piles, it struggles with liquids and small, heavy items. The vac had no issues picking up large washers but was less successful with small screws. This machine's storage system for the hose and attachments left much to be desired. As it is, the hose hangs out there, and one of its attachments is stored on the end of the hose. Still, for moving big piles of debris, this tool shines. For sucking up small heavy items or liquid, the Ryobi P3240 may be more suitable for the job.
The Bosch GAS18V-3 has features akin to traditional plug-in shop vacuums. It has a rigid hose with extension tubes that allow the user to stand up while using the tool. The hose is also quite sturdy and can hold its shape while bearing the user's full weight. Additionally, you never have to fight the spring-like action of a self-retracting hose.
Some of the strengths are also potential weaknesses. The hose and extension tubes are stored outside the machine, making the unit a bit cumbersome. Additionally, the hose doesn't retract — it has a fixed length of 72 inches, which means you won't get the increase in airflow that comes with a shorter or retracted hose. That said, in the right scenario, the Bosch is an excellent cordless wet dry vacuum. If you need more packability from your cordless vac, the Ryobi P3240 provides a retractable hose, great for those who value storage and compatibility.
Each wet dry vacuum was purchased at full price and pitted against each other in side-by-side testing. We pulled 16 gallons of water through these machines and took dozens of water lift measurements. We sucked up heaping piles of wet and dry sawdust and an array of heavy hardware items. We also tested the runtimes on each battery cell. Additionally, we measured and cataloged 18 unique features on these machines relevant to convenience, ease of use, and general performance.
Our testing of cordless wet dry vacuums is divided across four rating metrics:
Dry Work (40% of overall score weighting)
Wet Work (30% weighting)
Battery (20% weighting)
Convenience (10% weighting)
We perform multiple qualitative and quantitative tests within these metrics to compare and contrast each product. The result is a dialed-in overall score that gives better-performing vacuums a top rank in our lineup.

Analysis and Test Results
We selected some of the most popular cordless shop vacuums and put them all through rigorous testing. Our results indicate which products are general crowd-pleasers and which are best for specific situations. We include info that will help you make the best decision for your needs.
Worse Value
Better Value
What's the Best Value?
If a model costs the same amount as other products in the class but performs better, it is considered a value product. If a less expensive product performs at the same level as more expensive machines, it also has value.
The Kobalt and Ryobi models perform at the highest level in both wet and dry work, comparable to some of our favorite steam mops and vacuum cleaners, respectively, yet they ring up for significantly less than the average price for these tools, making them both a great value.

Dry Work
We focused a good deal of our effort on the dry work evaluation. Whether you just finished cutting wood for your latest DIY project, or are just trying to get some of the fur out of the dog bed, a dry mess is the most common reason to pull out any vacuum cleaner. Performance in this area accounts for 40% of the overall score. The evaluation consists of three sub-metrics of dry suction power: heavy debris (i.e., washers, nuts, bolts, screws, and 100-gram cylindrical weight); large sawdust pile (9 cups); and crevice cleaning. The first two do not use attachments on the end of the hose, while the crevice test uses the crevice attachment to pick up rice from a narrow slot.
The Kobalt and Ryobi models thrived in the heavy debris assessments. They both feature a highly effective combination of narrow hose diameters, high airflow, and decent suction. In the timed sawdust pickup, the Ridgid inhaled the pile in only eight seconds, closely followed by the Kobalt and the Milwaukee M18 at 13 seconds. As was confirmed in the wet sawdust tests (discussed below), the Ridgid's wide-diameter hose (combined with the lack of an elbow at the connection point with the canister) played a big part in this machine's success.

The crevice test assesses both the crevice tool itself and the reach of the suction produced by the vacuum motor. Here too, the Milwaukee, Ryobi, and Kobalt proved themselves to be top-notch. Their attachments penetrated eight or more inches and at least another half-inch of suction reach. Overall, Kobalt and Milwaukee lead the class in dry work.

Wet Work
Wet work contributes to 30% of a product's overall score, and we evaluate through a combination of 5 different tests. We began with a water drawing test, removing the filter and sucking two gallons of water from a height of 14 ½ inches — the height of a five-gallon bucket. Having replaced the filter, we then ran a wet sawdust pickup evaluation that is identical to the dry sawdust test with six cups of water added.
Next was the hard surface puddle test, where we employed the floor attachment to slurp up three cups of water off a linoleum floor. Of course, no wet work assessment would be complete without sucking water out of a carpet. We dumped two cups of water onto a floorboard mat, allowed it to soak in, and measured how much we could pull back out. Finally, we measured each unit's suction with a water lift gauge.
We were surprised at the degree of variability in these machines' performances across the tests. The Craftsman, Ryobi, and Ridgid were the best. However, none of these machines excelled in every category. The Craftsman and Ryobi came out on top by moving two gallons of water in just 9 seconds in the water drawing evaluation. As for the wet sawdust assessment, the Ridgid led the class at 15 seconds, and the Bosch a distant second at 31 seconds.
The puddle test illustrates the diverse tasks that these machines can tackle. As it turns out, the design of the floor attachment has more to do with success than suction. Those attachments with channels on the contact surface allow air to flow and messes to disappear.

The puddle tests proved to be a measure of the floor attachment design. Because they allow air to flow continuously, attachments with channels through the contact surface did best. The Ryobi and Craftsman came in at 25 and 27 seconds, respectively. In the wet carpet test, the Makita finally got into the fray, as well as the Ryobi and Craftsman; all of these models essentially sucked the carpet dry. Lastly, the water lift/suction test registered the Ridgid at 29 inches of lift, Bosch at 28, and Milwaukee at 25.

Battery Life
Battery life is arguably one of the most critical factors in any cordless product, accounting for 20% of the overall scores. We noted if the machine had a battery life indicator, compared battery types, and ran a timed battery test on each vacuum.
The DeWalt, operating with a 5 amp-hour cell, had the most impressive runtime of the group — just under 40 minutes. The Makita, also working with a 5 amp-hour cell, clocked in at 33 minutes 45 sec. Similarly, the Craftsman ran for 34 minutes.
Here's the twist. The Craftsman uses 4 amp-hour batteries. So, if we look at these outcomes in terms of runtime per amp-hour, the Craftsman ran for 8 mins 30 sec, whereas the DeWalt and the Makita ran for 7 min 56 sec and 6 min 33 sec, respectively.
Weight, dimensions, and hose length all play into the convenience of a particular vacuum. The toolbox-shaped machines are easy to store and offer the advantage of internal hose and attachments storage.

Convenience
Weighted at 10% of the overall score, convenience is not the most crucial aspect of a vacuum, but it plays a part in how easy it is to use a product. We measure the outer dimensions of the machine, the hose length (both retracted and at its maximum stretch), the weight, and the noise level at 3 ½ feet. Finally, we look at the filters.
The Makita makes a solid effort to check all the boxes. This model's toolbox design offers compact storage and below-average weight (8 lbs, 13 oz). Its HEPA filter is washable, and there's a prefilter option available for purchase. This model is also relatively quiet, registering well below average at 74 dBa. The only ding against this machine is its below-average hose length, 82 inches, when fully stretched. Other notably convenient models are the Ryobi, Bosch, and the Milwaukee.
Extension tubes are a rare accessory with cordless vacuums. If you need reach or want to stand-up while working, look for a model with this accessory.
