What should I look for when buying a Most Powerful Wet Dry Vacuum?

Before picking the best shop-vac, what features you need to consider are horsepower, cfm, portability, budget, and others. Below we elaborate those with details.

HP of your Vac

The first and foremost feature you should consider is the horsepower (HP) of the Shop-Vac. 

The higher the HP, the more suction power you will get from a shop vacuum cleaner.

But how much HP does a shop vac need?

It depends on what type of stuff you are going to clean. Generally, a Shop-Vac with 1-2 HP can perform better for small & gentle dust. On the other hand, for cleaning up stubborn debris, sand, and dust, a vacuum with 4-5 HP or more will be great.

In this case, DEWALT DXV16PA 16 gallon might be an excellent choice as it comes with 6.5 peak horsepower.

6.5 peak HP means the true power of the Vacuum that can perform the ultimate cleaning operation.

Cleaning Performance

When it comes to the performance of a shop-vac, most of us only consider the HP. But to know the real cleaning efficiency of a vacuum, you should also think about the CFM, AP, and suction.

  • CFM: CFM stands for Cubic Feet per Minute. It indicates the max airflow a vacuum achieves in its opening. The higher the CFM the better performance you will get.
  • AP: Air Power or Air-Watt is another feature you should take into account. It’s crucial if you look for a vacuum that can take on heavier stuff like nuts.
  • Suction: Suction, perhaps, the most crucial feature that also defines the cleaning ability of a vac. Generally, the suction is measured by the inches of water a Vac can lift up. We recommend you to pick a vacuum that can lift the water up to 75 inches.

Cord Length

The cord length of a Vac also matters a lot for effortless and optimum cleaning performance. A vacuum comes with a long cord that allows you to clean the hard-to-reach areas with ease. Regarding this, DEWALT DXV16PA can be your next go-to shop-vac as it includes a 20′ extra-long cord.


For optimum cleaning performance, always consider a shop-vac that comes with the below accessories.

  • Crevice tool
  • Nozzles
  • Extension wands
  • Car nozzles
  • Wet nozzle 
  • Filter
  • And a lot

Fortunately, most of the shop-vacs on this list include multiple accessories. So, you can pick any of them from there.

Built-in Blower

A vacuum that comes with a blower is always a plus. It lets you clean up debris and dust from hard-to-reach areas. Also, consider the vacuum that includes a drainer to remove liquid.

The vacuums that come from Dewalt, Vacmaster, and Craftsman on this list integrated with a built-in blower or blower port.


Portability is another feature you should reckon with. We recommend you to pick a shop-vac that comes with a wheel or handle. As a result, you can easily lug it around your job site and perform the cleaning workflow with ease.

On-board storage

The on-board storage system helps to keep your essential accessories like nozzles & hose organized and within your reach. 

So, you don’t need to hustle to get the equipment when you need it most.


The price of a shop-vac also influences your buying decision. If you are on a tight budget, then Vacmaster Professional Vac will be your best bait. Though the price of it is low, it doesn’t sacrifice the cleaning efficiency.

Is a shop vac more powerful than a regular vacuum?

Regarding design, HP, tank capacity, suction, and airflow, shop-vac is superior to the regular vacuum.

We know that the shop-vac is specially designed to clean woodworking shops, garage, or construction sites. So, it comes with strong suction to pick up screws, metal pieces, and other types of stubborn stuff.

On the other hand, a regular vacuum cleaner is specially made to clean homes or small apartments. So, generally, the regular vacuum cleaner comes with less strong suction compared to the shop-vac.

Apart from these, a shop-vac comes with more horsepower, CFM, and AP than the regular vacuum.

So, we can say a shop-vac is stronger and powerful than the counterpart- a regular vacuum.

Which Shop-Vac has the most Suction

Without any doubt, Dewalt is the best shop-vac for its ultimate cleaning ability, durability, and portability. The 6.5 peak HP motor and high airflow (cfm) provide strong suction to handle heavy dust from large job sites. Besides, it’s built-in drain lets you remove wet materials like liquids.

On the other hand, if you are on a budget but looking for a shop-vac for cleaning most of the workspaces, then Vacmaster Professional Wet/Dry Vac might be your go-to Vac.

Still, it’s your personal preference, which one from the list you are going to pick. Remember, the shop-vac you will select impacts on the cleaning operation.

Best Suction Shop Vac FAQs

What is peak HP on Shop-vac?

The word ‘peak’ is used to rate the horsepower (HP) of a shop-vac. Generally, it indicates the amount of electrical draw of a vac when it gets overloaded and stalls.

In other words, the peak HP refers to the motor output that measures in the laboratory through testing.

However, the horsepower rating number isn’t the best way to understand a shop-vac’s cleaning performance. Experts also recommend considering amps, suction, cfm, tank capacity, and airflow to know the true power of a Vac.

What is CFM?

CFM stands for “cubic feet per minute.” It measures the volume of air that a shop vac can move. The higher the CFM rating, the more powerful the vacuum system and thus, with a high-powered vacuum cleaner you won’t have to clean as often because it will suck up all those pesky crumbs that are stuck in your carpet!

Why is my shop vac blowing out dust?

The shop-vac blowing out dust for the following reason:

  • There has a hole in the filter
  • You can’t install the filter properly.

If your shop vac blows out dust, make sure you install the filter precisely. Otherwise, it would be best to replace the filter.

Can shop-vac clean carpets?

Yes, shop-vac can clean carpets. But we recommend you to use your general vacuum cleaner to suck up carpeted floors. The reason behind not using shop-vac is its extra suction. You can’t move the shop-vac when vacuuming on the carpet.

Final Words

Handling stubborn dust like screws from construction sites, you need to have a high-efficient shop-vac in your lineup.

A Vac aligned with an immersive motor, strong suction, higher cfm, built-in blower port, and others is considered as the most powerful shop-vac.

Regarding those features, Dewalt is the best wet-dry vacuum on this list. It comes with a 6.5 peak HP motor, higher cfm (116), and large tank capacity. As a result, you can pull up almost everything from the construction sites with ease.

In contrast, if you are on a tight budget but looking for a premium shop-vac to handle heavy dust, then Vacmaster Professional Wet-Dry Vac will be your perfect bait.
