Yeh, they can take some getting used to. My parents purchased a top-loading, high-efficiency washer with no agitator, and my mom didn't like it at first because it was new and different. But now she likes it.Both are installed now in my laundry room. I am washing clothes. It is definitely different. The lid locks and I hear some clicking sounds. As I said, there is no agitator. I used the quick start guide for directions until I have time to read the manual. So far, I like.
My washer is front-loading, so it washes by tumbling...just like a dryer. I love it.
