The challenge

HAIs: a growing threat to hospitals.

As patient numbers climb, so does the risk of infection. Hospital-acquired infections strain resources, boost readmission rates and disrupt daily operations. It is a global crisis impacting millions.

$100bn+

estimated annual global cost of HAIs

~50%

of high-touch surfaces missed in manual cleaning (Jefferson et al., 2011)

$300k+

annual savings for a 100-bed facility from UV-C (Raggi et al., 2023)

Current challenges

Why traditional methods fall short.

Manual disinfection is time-consuming, labour-intensive and prone to human error. Chemical disinfectants struggle to eliminate all pathogens, especially as antibiotic resistance grows, and standalone UV-C devices have limited coverage and need manual handling.

Antimicrobial resistance (AMR) is rising through overuse and misuse of antibiotics and disinfectants (Salam et al., 2023; Tong et al., 2021).
Chemical limits: common disinfectants achieved only an average 3-log reduction (Di Martino et al., 2021).
Human error: 50% of high-touch operating-room surfaces are missed during cleaning (Jefferson et al., 2011).

Proven effectiveness

The evidence for UV-C.

Combining UV-C disinfection with manual cleaning is consistently more effective than manual cleaning alone.

38%

reduction in acquired infections when UV-C was integrated (Kovach et al., 2017; Jinadatha et al., 2014).

57% / 53%

reductions in C. diff and MRSA infections with UV-C disinfection (Fornwalt et al., 2016).

24.6 pts

reduction in MRSA and VRE surface contamination after UV-C treatment (Wong et al., 2016).

Cost savings

A smarter, more cost-effective future.

Study	Setting	Reported saving
Raggi et al. (2018), Am J Infect Control	377-bed community hospital, USA	US$1.22M direct cost savings over 12 months
Pegues et al. (2016)	Hospital of the University of Pennsylvania, USA	US$350k–1.5M estimated per year

The Ryberg answer

Autonomous. Reliable. Efficient.

Omnia addresses these challenges through autonomous, chemical-free disinfection that eliminates human error and ensures thorough coverage. Its dynamic movement minimises shadow areas, and its compact design, which can rotate around its axis, reaches tight spaces larger robots cannot.

Dynamic movement minimises shadow areas for greater pathogen exposure.
Chemical-free: eliminates human error and reduces environmental impact.
Compact design reaches tight spaces and requires minimal storage.
Grounded in scientific research, with proven results in hospitals worldwide.
