New Study Confirms Autonomous UV-C Strategies Outperform Non-Autonomous Methods in Hospitals

by | Jan 30, 2023 | Press Releases

SAN JOSE, CALIFORNIA, UNITED STATES, January 31, 2023 / — A new research study has revealed that the OhmniClean autonomous UV-C disinfection robot significantly improved UV-C exposure on surfaces that were distant, angled, or shadowed compared to non-autonomous strategies. The study was conducted by UV disinfection experts, Clean Sweep Group, Inc., in collaboration with researchers from Providence Holy Cross Medical Center and the University of North Carolina at Chapel Hill.

The purpose was to quantify the difference between manual and autonomous disinfection strategies. “Before this study, the relative performance advantage of autonomous strategies – where a robot like OhmniClean is capable of moving to multiple places in one room on its own – was unclear,” states Cody Haag, lead researcher. “So we were interested in showing whether autonomous systems are more effective than what is typically used in a hospital setting.”

The research team placed EIT UV Key light sensors in multiple patient care settings and compared the UV-C doses achieved on surfaces using both autonomous and non-autonomous strategies for equal periods of time, according to each manufacturer’s recommended protocols.

The OhmniClean autonomous robot more than doubled the overall amount of UV-C light on the sensors and was able to provide UV-C light on surfaces that were entirely shadowed by non-autonomous light emitters.

According to lead researcher Cody Haag, “Our findings are important because UV-C light is more consistently distributed across surfaces with autonomous systems, thus required dosages are achieved quicker and rooms may be disinfected faster than with non-autonomous systems.”

Thuc Vu, CEO and Co-founder of OhmniLabs, stated, “We are thrilled to see such significant results from the autonomous UV-C placement. Autonomous technology is likely the most effective technology to help eliminate pathogens and hospital-acquired infections. The study’s findings have important implications for hospital administrators and infection control professionals as they work to keep patients and staff safe.”
