CSGI DISINFECTS YOUR FACILITIES WITH OUR UV-C ROBOTS.

Hospitals, nursing homes, professional sports facilities, cruise ships — Clean Sweep Group, Inc (CSGI) has disinfected it all. CSGI was founded in 2011 by healthcare industry veterans Leo Williams and Mark House with the belief UV-C could reduce the risk of infection in a variety of settings.

Along the way, CSGI participated in two peer-reviewed clinical trials showing significant reductions of hospital-acquired infections (HAIs).1,2 In one study, the hospital saved over $1.2 million in excess HAI cost using CSGI.2

During the SARS-CoV-2 pandemic, CSGI disinfected their partner hospitals and expanded use of the technology in commercial settings.
