How Does the Shop Vacuum Work?
The laws of physics decree a few truisms when it comes to wet/dry vacuum operation. For one, the stronger the motor and larger the size of fan blades, the greater the suction force generated. Most vacuums come with various sizes of attachments that can be placed on the end of the suction rod. A narrower attachment focuses the air flow and allows you to pick up heavier pieces of debris. The particular attachment you choose varies depending upon the job at hand.
