How To Choose The Most Powerful Shop Vac?
This is, of course, one of the major factors to think of when buying a shop vac.
The most powerful shop vacs come with the best motor that can offer high horsepower. While the horsepower of a shop vac should be at least 5, it’s also important to balance between the horsepower and the electric current.
You can choose a motor with high horsepower, but if the electric current of the vacuum can’t handle that power, it’s no use. The best electric current is 120V or higher.
Another factor you must consider when choosing a shop vac is how much it can contain.
Since shop vacs are specialized for workshop environments, which are larger and wider than regular houses, they need an adequate capacity to hold all the liquid and debris they will suck in.
On the other hand, the tank cannot be too big for you because you won’t be able to carry it around if it’s too heavy. Therefore, remember to balance between capacity and weight.
The best capacity for a shop vac is between 40 and 50 liters. A tank smaller than that won’t likely contain enough debris or liquid when you clean. Meanwhile, a tank larger than that is too heavy that you have trouble or cannot move it around at all.
Besides the capacity, the cord length is another thing involved in choosing a shop vac for the same reason of moving around while the plug is fixed at one spot.
Workshops or similar places are much larger than a regular house and you must move to various spots to clean them.
A cord long enough will allow you to clean the whole place without having to unplug the vac then re-plug it at another spot but a short one will make you frustrated.
Different from horsepower and tank capacity, choosing a cord length completely depends on how big the place is.
We suggest you measure the place first to come up with an ideal cord length, then when choosing the shop vac, remember to check the cord length and see if it’s suitable.
Of course, a cord a bit longer than the ideal length is better than a shorter one.
Which Brands Make The Most Powerful Shop Vac?
This is probably the most popular shop-vac maker with more than 65 years in the market. It offers product models with various sizes and features.
It's a brand owned by Cleva North America, Inc., producing wet/dry vacs with tank capacity from 9 liters to 60 liters.
This brand is famous for not only a pro but also homeowner construction tools. It has expanded its business to the shop vac market for a while and has become one of the best shop vac brands too.
Are shop vacs more powerful?
Shop vacs are more powerful than standard vacuums, for sure. They have bigger and tougher hoses to deal with chunkier and sharper pieces of debris.
How high can a shop vac lift water?
Generally, a shop vac can pump up to 23 liters per minute, and lift to about 1.5 meters high.
How many CFM is a shop vac?
This figure varies among different models with different specifications. But for example, a shop vac with the highest horsepower of 6.5 and an electric current of 120V can produce 185 CFM of airflow.
Is a dust collector better than a shop vac?
If you only need to clean dust, a dust collector is the best for the job, but if there are debris and liquid, a shop vac is better overall.
How long do shop vacs last?
On average, a shop vac lasts 8 years of use, but this changes depending on the brand, model, and the user.
Overall, three key factors to consider when choosing a shop vac includes horsepower, tank capacity, and cord length.
For the best shop vacs, you should visit some big brands like Shop-Vac, Vac Master, or DeWalt. Good luck with choosing a perfect shop vac. Thanks for reading!
