Good English

Today i was down in the laundry room and happen to notice this as the name of one of our dryers.

Okay, the steam dryer part makes sense, but what about the line below it?

Does that mean the machine spins the clothes around in an oval or almost round motion? or does it mean that the inside drum is almost round? Or could it be that this was sold as a discount because the manufacturing process was a little off, where the correctly put together machines say "simple round clothes dryer"?  But since it was close and the thing still works well they just say "roundish"?

Or, and most likely, is it just a simple case of great English :). ?
