The noise coming from the floor cleaner that's pushed along the hallways is a vexation to anyone's soul. I visited a man who is dying and even with my ear by his mouth I couldn't hear him because of that very loud machine. I know there are quieter ones. The comfort of patients and visitors alike would certainly be worth the cost of a quieter model. A patient's and a visitor's mental and emotional health is important. I really wanted to destroy that thing.
