A robot first introduced in late 2010 has proven effective at helping hospitals cut costs and save lives by blasting ultraviolet light to clean rooms and help prevent life-threatening infections. The UV Disinfection System, made by Xenex, is credited with decreasing Clostridium infections at St. Joseph’s Hospital Health Center hospital in Syracuse since last summer,the Post-Standard reported.
As the company points out, UV light has been known to kill bacteria since the 1950s and UV sterilization devices have long been used to protect water sources, food and more. Their robots (which ran St. Joseph's $120,000 for two) use higher blasts of UV light, making it possible for them to clean rooms quickly rather than having to be on for a prolonged period of time. Which means the robots (which resemble R2D2) can be moved from room to room, for a quick, effective and apparently price-friendly clean.
