Recent expert discussions and supporting studies reiterate that UV-C devices (including robotic systems) can meaningfully reduce residual bioburden on surfaces and in air but do not substitute for thorough manual cleaning and disinfection. Effectiveness varies substantially with device design, cycle time, positioning, shadowing, and prior soil removal; short cycles or suboptimal placement may yield only modest log reductions against resilient organisms such as C. difficile spores.
Infection-prevention and environmental-services leaders emphasize that technology should enhance, not compensate for, core hygiene programs. Facilities are advised to optimize staffing, training, product selection, contact times, and monitoring first, then layer validated UV-C as a targeted adjunct.
