Efficacy of UV-C disinfection robots confirmed by VA study

Using continuous ultraviolet-C disinfection robots was proven to be more effective in killing pathogens than pulsed xenon devices in a recent study, funded by the U.S. Veterans Administration.

Researchers ran a UV-C robot on pathogen-covered glass slides for the same length of time (10 minutes) and from the same point as a pulsed xenon device, and found the PX device showed a surprisingly low pathogen kill rate for Clostridium difficile and vancomycin-resistant Enterococcus, even as close as 4 feet.

The continuous UV-C robot demonstrated a much higher pathogen reduction rate for the C. diff, methicillin-resistant Staphylococcus aureus and VRE in even less time than the PX device, which left behind considerable residual contamination.
