This steamer includes ozone and an aromatherapy basket for essential oil treatments.  The unit runs for 60 min with an autoshut off and has a flex steamer arm that moves at the top of the arm instead of the whole arm moving.  It can move up, down and sideways and the steamer head can pivot as well.  The digital timer is silent except when you program the time and settings at the beginning of the treatment. 32" H x 16" W x 14" D.
