How To Choose The Most Powerful Shop Vac

There are a number of considerations you should make when choosing the most powerful Shop Vac. Here are some of the key considerations.

Motor Performance

The motor is the main source of power for the vacuum so you need to have one that produces high horsepower. In most cases the horse power should be 5 and above but at the same time you need to realize that the horse power should correspond to the electric current the vac uses. You could have a powerful motor but if the current is not enough to drive it, it may not perform to its potential. 120 volts or more is adequate. You should also consider what materials the motor deals with best- glass, dust, liquid etc

Tank Capacity

The size of the tank is very important because if the motor is powerful, it is going to suck in a lot of debris and the tank should be able to accommodate all that and you do not want to have to empty it all the time so it needs to be big. At the same time though, you do not want a tank that is so big that it becomes too heavy for you to lift when it is full. Ensure that the tank capacity is at least 10 gallons and not more than 14 gallons or else you will have trouble moving it around especially if there are no wheels.

Accessory Tools​

​The most powerful shop vac needs to have all the necessary tools to ensure it can suck up all the dust, regardless of the surface. You will be dealing with wet and dry debris so the tools should be appropriate for that. Different tools offer an advantage on particular surfaces for example.

  • The crevice tool is handy in tight spaces like between cushions in a car and cracks
  • The brush tool helps to loosen dust that may have dried or lodged on a carpet
  • The floor tool is obviously good for getting dust off the floor

Length of the hose and cord

Dust has the ability to fly and settle all over the room so it is important that you are able to reach every area of the room. Consider how large the room you will be using the powerful Shop Vac is and then see if the length of the hose and power cord is sufficient to give you the needed reach or will you need to get an extension cable to be able to use the same socket and still cover the required radius of the area you are cleaning up. It can be very frustrating realizing that the cord and hose are just not long enough to reach wherever you intend to clean.

Other Considerations

  • Price is also a big consideration as you want to be able to get something that you can afford but also something that is worth the money
  • It is also important that the shop vac you get is durable. Choose one with a warranty of more than 1 year
  • If you will be moving around a lot, it is important that you get a shop vac that allows you easy mobility in terms of weight or added features like wheels and handles.
