Weighing in at 26 lbs. and approximately 21x23x26 inches, the Craftsman CMXEVBE17595 model is fairly large, so users inside of a structure with typical door widths will need to watch out for door frames. But this model also is pretty quiet for the amount of power it puts out making it a great machine to use indoors or out. Rated at 177 cubic feet per minute flow, this is the shop vac with the highest CFM of all the shop vacs we reviewed, making it an excellent machine to use for all kinds of wet or dry vacuuming.

How have we chosen the shop vacuum on this list?

When it comes to choosing a good wet/dry vacuum, there are several factors that you should consider: motor size and horsepower; tank capacity; and accessories or attachments that come with your purchase. You want to be sure you are investing in the right product.

Of course the best way to choose the right shop vac is to do extensive research and go through comprehensive guides like the ones we created to help you consider the important factors. We strive to provide you with the most recent and up-to-date information on products and things to consider when shopping around.

Brand’s Reputation

Our suggestions include top manufacturers because these brands have high quality products.

Customer Reviews

We rely on recommendations from genuine users because no one can tell about a product better than a customer who has tried and tested it. We didn’t simply go by power ratings alone. We also took into account how well these vacuums were built and for what environments they are best suited.


We’ve broken down our picks into three categories: budget, intermediate, and premium. Prices range from $33 to over $100, but there’s a model for every budget. We tested all of these shop vacs for their performance at picking up dirt and debris, as well as how long each one would run on a full tank of power. In addition to our own testing, we also consulted customer reviews to see which models stood out from others in terms of overall value.

What to Look for in a Most Powerful Shop Vacuum

When shopping for a shop vacuum, it depends on your specific needs as they come in many different sizes and styles. First, determine whether or not a wet/dry vac would suit your cleaning job better than a standard upright or hand held style. While there are many different brands and styles to choose from, it’s important to note that most come with similar features.

Air Watts

To start off your search for a good wet/dry vac , take a look at its CFM rating — or cubic feet per minute — which indicates how powerful it is overall. This measurement gives you a general idea of how well your new vacuum will handle both liquid and dry debris. You might also want to look into whether or not your new vac offers airflow control — as well as high and low settings — which allows users to adjust suction based on job requirements.

Safety Features

If safety isn’t a big concern for you, then weight might be. On average, shop vacuums tend to weigh anywhere between 10 and 30 pounds without water. Also keep in mind that most models don’t include wheels. Nevertheless, if mobility does matter to you, consider investing in a lightweight backpack vacuum instead of a corded or cordless unit because they provide comparable performance but offer more freedom of movement. Lastly, some models even feature padded backstraps to make lugging your vacuum around a little easier.


Whether you only clean up small messes every now and then or find yourself handling larger projects often, maintenance is key for prolonging your wet/dry vac’s lifespan. Although portable vacuums typically don’t require maintenance, you should still follow a few tips to keep your machine working properly. For example, try to avoid submerging your machine in liquids and always wash out tanks and filters after each use. If you notice that suction doesn’t seem to be as strong as usual, unclog tubes and check them for clogs. Otherwise, it might be time to replace damaged parts altogether.

Specifications to Consider When you’re ready to buy a shop vacuum

When you’re ready to buy a shop vacuum, it’s important to look for specific criteria that will help you narrow down your selection. Here are three of those specifications to keep in mind before making your final decision.

Cord Length

It might be convenient for vacuums to be cordless or designed with retractable cords, but keep in mind that wires can get caught or wrapped around objects within your workspace. If you think you’ll be tripping over wires on a regular basis, consider choosing a vacuum with a cord. The length of your cord will determine how far away you can stand from your outlet, which means it’s important to choose one that will give you enough room to work comfortably. However, be sure not to select one that is too short as it might cause problems when trying to move around your workspace.

Accessories and Attachments

Along with a standard hose, look for vacuums that come with other accessories. Your vacuum might come with a foam cannon or dust brush to help tackle your cleaning tasks faster and more effectively. Plus, you can save money on accessories if you invest in a vacuum that comes packaged with what you’ll need most. Budget Last but not least, decide how much you’d like to spend on your new shop vacuum before diving in to shop around.


What is the highest CFM shop vac?

The shop vac with highest CFM we reviewed is the Craftsman CMXEVBE17595 model. With strong cubit feet per minute of 177, Craftsman’s wet/dry vac is able to suction at the highest rate of all of the machine models we reviewed. Having a high CFM is important when also paired with a strong horsepower, as both combined together produce the most power in a wet/dry vacuum.

How many CFM is a good shop vac?

Most shop vacs that are powerful enough to get the job done have a CFM of at least 150. A good shop vac that just exceeds this is Fein Turbo I Wet/Dry Dust Extractor, clocking in at a respectable 151 CFM suction capacity. A good shop vac should be able to move at least 150 cubic feet per minute of wet or dry materials effectively.

What is a good horsepower for a shop vac?

Shop vac power is first measured in the HP or horsepower. A good shop vac HP is around 6 or 6.5, like the Vacmaster Professional Wet/Dry Vac. HP is measured as the ability to reach that HP at peak performance, and a shop vac like Vacmaster’s does that with a peak HP of 6.5.

Which shop vac has the strongest suction?

For a wet/dry shop vac with the strongest suction, the Dewalt DXV16PA 16-gallon Poly Wet/Dry Vac is a great option. This machine is super strong, owing to its peak of 6.5 HP and its solid, tight construction and variety of accessories that focus the machine’s suction power.

Can I use shop vacs at home?

Yes you can, as the use of wet/dry shop vacs for home needs is possible with many units. We recommend the Workshop Wet Dry Vac WS1600VA for at-home jobs for a few reasons. It is only about 23lbs., and it comes with an attachable accessory bag to keep the attachments close at hand. Its maneuverability and lower noise volume both add to Workshop’s Wet Dry Vac being our pick for a good machine to use at home.

What Can Shop Vacs Do?

A shop vac can do every type of cleaning workflow. You can vacuum the floor to pick up dirt, dust, and filth from the surface.  Therefore, it is powerful enough to pick up nails or wood dust from a workspace. On top of this, you can also pick up wet messes with a shop vac. Indeed, it’s a hybrid vacuum to suck away both wet and dirt messes.

Is a shop vac more powerful than a regular vacuum?

Yes, a shop vac is more powerful than a regular vacuum. It comes with a powerful motor, which delivers cyclonic suction to suck away every type of filth. Due to its greater suction, you can pick up both wet and dry messes like a charm. Indeed, a shop vac is a powerhouse in the field of vacuum to clean both wet and dry dirt.

Can I increase the suction on my shop vac?

Yes, you can increase the suction on your shop vac. Just upgrade the existing filter with the highest flow rate filter to boost up the suction of your shop-vac. However, there is no need to get a high-flow rate filter if the foam wet-dry filter works the best.

Why is there a ball in a shop vac?

You can find a ball in your shop vac. This ball will float to the top of the tube and turn off the suction to prevent the water from entering the fan and motor. Indeed, it functions as a fan and motor protector by preventing the water from getting into the motor.

Is a shop vac the same as a wet/dry vac?

Yes, a shop vac is the same as a wet-dry vac. Most shop owners, especially construction shop owners use the wet-dry vacuum to collect both water spills and dry debris & dirt. As people find the wet-dry vacuum in the shop often, they call it a shop-vac.


If you’re a do-it-yourselfer, an upgraded shop vacuum is a must-have tool. With some brands under $35 and others around $200, there’s no reason not to have one on hand. In fact, if you’re going to spend money on a vac, make sure it’s as powerful as possible. Keep in mind that a large capacity doesn’t always mean more power. Instead, look for a model with high airflow levels that means more suction power and filtration designed for fine dust particles that can harm your lungs or clog up your tools. A good dust bag may not be enough to protect you from these dangers.

The best models also include a sealable compartment for wet items like paint, chemicals, and anything else that might ruin a floor or stain other work surfaces. And don’t forget about accessories! A variety of add-ons are available to help keep garage cleanup tasks simple and efficient.

Ultimately, shop vacs provide incredible convenience in both workshops and homes they save time, money, and effort by eliminating trips to the dump or cleaners every time you spill something on your carpet or countertop. When it comes to these handy tools, you get what you pay for: cheap ones may seem cheaper in price but will only prove more expensive in terms of both safety and convenience down the road. So shop around — we did — and choose one that does everything it should do without costing too much.
