Terri likes to vacuum the carpet, it is one of her chores she does every other day.  After school, she has a small list of little chores to do around the house.  She has to vacuum the living room and hallway for those days.  So, on one of these days, she takes out the vacuum cleaner, unwinds the cord, plugs it in, and adjusts the height of the vacuum.  This way, it is low to the ground, and gets all the dirt up.  She then hits the button for start, and it turns on.  She pushes it gently across the carpet and floors of the living room and hallway. She makes sure that she gets the edges and under any carpets that are movable. She also vacuums under the front of the couch.  When she is done, she turns off the machine, empties the dirt into the trash can, and pops the container back onto the vacuum.  She rolls up the cord, and returns it back to the closet.
