They can't simply go back and forth because otherwise they wouldn't move anything.
If a boat moves itself because it pushes the water, then it has to change the position of the oars (take it out of the water and rotate it) in order to repeat the movement.
If cilia also don't change their position, they would simply move the mucus back and forth and it wouldn't get anywhere. Cilia also rotate in another direction to reach their starting point.

When you row a boat on the pond why does the boat go forward when you are pulling the oars towards you?
When you row a boat on a pond, you are usually facing the back of the boat. Also, the oars are usually attached in the middle of the oar to the side of the boat. So if you pull the handle of the oar towards the front of the boat (towards you when rowing), the paddle of the oar is moving towards the back of the boat (the oar acts like a lever-arm). To move a boat forward, you actually have to move water backward! It's pushing water back that really moves the boat forward. So, when you pull the oar towards you, the paddle moves towards the back of the boat, and that pushes water towards the back of the boat, pushing the boat the opposite direction, which is forward! Just make sure to turn around once in a while because you're not looking where you are going!
WHICH FORCE CAUSE THE BOAT TO MOVE?
It could be tides, or waves, or wind. It could be a movement of cargo or people in the boat. It could be propulsion by oars, punts, paddles, propellers. There is not enough information to answer the question.

What is an everyday example of cilia?
Little hairs that direct dirt and debris out of system... We have cilia in our nose, lungs, and even our inner ears. Probably other places as well... I'm just not sure where else. The cilia in our inner ear helps us hear. The cilia (ciliated epithelial cell) helps clean out our lungs and if we smoke our cilia may stop working which means our lungs will get cloged up and you'll find it harder to breath. Easier: Hairlike structure arranged in tightly packed rows that projects from the surface of some cells.
