How does a shop vac actually work?

Answer 1

"A shop vac is still a vacuum cleaner. Those contraptions work be creating a negative pressure that sucks in unwanted particles, like dirt, into a holding container that filters the air out to prevent the majority of its contents from flying out."

Answer 2

A shop vac is a type of vacuum cleaner that uses a powerful motor to create suction. The motor creates a negative pressure in the vacuum, causing air to be drawn in through the intake port. As the air passes through the vacuum, dirt and debris are picked up and collected in the dirt canister or filter. The filtered air is then released back into the environment.
