Did you know that the word root ‘vac’ comes from the Latin words vacare or vaco, which mean ‘unoccupied’, ‘idle’ or ‘void’? Many English words with this root are related to the idea of ’emptiness’. Something that is vaccant is empty or unoccupied. To vacate is to leave an area or to make something unoccupied. A vacuum is a space that does not have any gas, liquid, or solid matter in it; or a space that is not filled. A vacation can be filled with free, idle, or unoccupied time. Can you think of any other ‘vac’ words?

A vacuum cleaner works by using a fan to create a partial vacuum inside the machine. Since the air pressure in the machine is lower than the air pressure outside of the machine, ambient air flows into the vacuum cleaner. Loose dust and debris is carried into the vacuum cleaner and trapped by filters or other air pressure changes. The rotating brushes in a vacuum help to dislodge dirt and dust so it can be caught up by the air stream.
