This is an amazing steam cleaner. I used it to clean a 30 year old Jen aire stove in the house Im renting. I was able to get old grease and grime off that I hadnt been able to get clean since  I started renting this place 4 years ago.    I gave it 4 stars instead of 5 because the orange light comes on after a minute or so of steaming. Not sure why. It still worked, just a bit confusing.
