Do Vacuum Cleaners Push Or Pull?

    Strange things you sometimes learn about physics, there really is no such thing as suction. The outside atmosphere is usually pushing in, in fact.

    And there is a lot of air pressure on the surface of the earth. You just don't notice it because it is equal all around you.

    But I have just one question: When you use a vacuum cleaner, are you pulling the dirt in? Or is the atmosphere pushing it in? Because that last one seems confusing to me.I know the vacuum cleaner does create a partial vacuum (hence the name).

    But back to my question: Pushing? Or pulling?

    Ok I got a question for you. Is a fan pushing or pulling air?

    A vacuum cleaner works on the principle of a vacuum.

    In theory there is nothing in a vacuum, so nothing can be sucking the air in, it has to be pushed from a higher pressure, non vacuum region.

    A vacuum cleaner operates on a partial vacuum, but the principle is the same.
