I have a HE top loader. Mine is about 3 years old, so things may have changed,but I won't buy an HE washer again regardless. It has too many drawbacks that they don't mention.
I have two questions regarding them: If they are so great, why do you have to use/buy special cleaning agents to keep the machine from stinking? If you have to clean your washer, how clean is it getting your clothes?
I'm sorry, I can't answer the question regarding washing a queen sized quilt.
