This is a great product, offering the added flexibility of working as a handheld steam cleaner. It heats up very quickly. Although I am very pleased with the product, there are several things about it that I think need improvement: 1) I would rather have the ability to directly fill the unit with water, or have a detachable fill tank that can be easily filled and emptied in the sink; 2) The flexible head is too loose, it make the unit a little hard to maneuver -  I wish the head would partially lock in the straight ahead position, but swivel with application of a twisting force; 3) It needs to stand on its own. Thank you.
