How Does A Shop Vac Work

A shop vac is designed as the regular vacuum cleaners with a few modifications made in it.

They are meant to do all the cleanings that the regular vacuum cleaner can not do along with those which can be done by the regular ones.

How does a shop vac work actually defines all these queries as they define the working criteria along with the process of its working.

The different parts of the shop vac are built to complete a particular work.

And that clearly defines the vast working capability of the shop vac for your home and the workspaces.

The shop vac actually extends the idea of the regular vacuum cleaner and cleans a larger area.

It is designed in such a way that it can pick up the larger size of the dirt along with the wet particles laid around the place.

This type of cleaning is essential and also very difficult in the larger factory area or the workshops.

And this is the reason the shop vac is idle for such areas to clean. But that does not mean that you can not use them in your house.

Rather than you can use them wherever you want.

But the major obstacle of using a shop vac in the house is that it is not that much efficient in picking up the tiny debris or dirt from the area as the regular vacuum cleaners can.

Without this, you can easily use it to clean up your house and make your work minimize.

Read the following section to know more about the process of how a shop vac works and what are the benefits and restrictions in it.

How Does A Shop Vac Work


The shop vac are larger in size in comparison to the regular vacuum cleaners. As they come up with a larger size, they offer much more power than the regular ones.

Which means you can pick up a lot more dirt from the place and with much more power. The power minimizes the time of the work to make it fast to work.

There is a motor placed on top of the head of the cleaner, which creates the power when turning on and creates the pressure in the bucket to suck all the dirt from the outside.

Working process

The fan and motor sitting on top of the shop vac takes away the air from the inside to create low air pressure inside the bucket.

That low air pressure calls up for more air from the outside to fill in the vacant place.

And this way, using the handle or the pipe of the cleaner, the dirt is picked up and transported inside the bucket.

The fan continues to create the pressure in the shop vac, and the inside pressure brings in more air along with the dirt to fill and clean.

The whole process takes place so fast that it is sometimes difficult to see the dirt moving from the place.

The suction of the dirt also depends on the horsepower of the shop vac you are using. The size of the shop vac also affects the amount and ratio of dirt cleaning and time.

Dirt storage system

The shop vac has a bucket inside the machine to hold up the dirt rather than having a bag to hold them.

Having a bucket helps the shop vac to hold up the wet debris along with the wet particles.

The excessive airflow sucks away all the dirt and wet elements and stores it in the bucket inside it.

You can easily open up the head of the cleaner and take away the bucket to empty at any time.


The shop vac can come along with many helping tools like the different heads for the vacuum head.

The different size heads help to clean the different areas and different particles.

As the shop vac can clean up the wet dirt also, it needs a special head in comparison with the regular vacuum cleaners.


The larger the horsepower of the shop vac is, the larger the fan gets. The larger fans create more pressure in the shop vac to pick up the wet debris from the area.

Normal vacuum cleaners do not come in with larger horsepower. That is why they can only pick the small particles and dry elements

. But the shop vac can pick big and wet elements and clean a larger area in the low time.

Cleaning process

The cleaning process of the shop vac is pretty simple, as it takes a few minutes to accomplish.

You can easily take off the head of the cleaner and take out the bucket inside it. The bucket basically holds up the dirt of the cleaning.

You can wash the bucket in the water and then dry up to place it inside the shop vac again. Besides, using a brush can help you to clean the fan of the shop vac in no time.


The shop vac also have wheels attached like the normal vacuum cleaners to move around the place to make the cleaning easy.

Just make sure that you do not pull the shop vac using the rod to do it.

It will make the joints loose and make your shop vac leak air to slow down the cleaning process.

And if you somehow create a leak on the shop vac, then the formula of the low air pressure will not work and will end up giving you a broken shop vac to clean with.

These things should be known before you start to use a shop vac for the cleaning process of your workspace or your home.

Whatever purpose you use it for, make sure to remove the bigger particles with your bare hands in the first place to ensure a good cleaning and make the place neat and tidy.

Because a machine can not give you the fullest of the detailed works as you can do.

But they can minimize your workload and make the work easy for you if you follow the right process to work with.
