Many top loaders do not have an agitator but there are some out there. I hate my new energy efficient washer. You can't adjust the water level. The machine knows how much water to put in--I don't. I do not have an agitator and the clothes get very twisted. I talked with a young salesman recently and he said the less water the better cleaning because the clothes rub up against each other. I wanted to tell him he had been brainwashed by the company. (Sorry for the sarcasm.) I would love to have my 1990 washer back. It lasted over 25 years. I was told the new one won't last over 10 years. Hopefully by then there will be some better choices.
