UV disinfection is a powerful tool used widely to eliminate harmful pathogens. However, it is challenged by ‘shadowing’ – an issue where areas targeted for disinfection aren’t fully exposed to UV light due to physical obstacles. These shadowed regions can harbor unneutralized pathogens and microorganisms, negatively impacting the effectiveness of UV disinfection. In this blog, we’ll delve into the significance and implications of shadowing in UV disinfection and demonstrate how autonomous UV robots like OhmniClean can mitigate the issue.
What is Shadowing?
Shadowing occurs when physical objects present within the disinfection environment obstruct the UV light, preventing it from reaching certain areas. Much like the shade cast by an umbrella under the bright sun, shadowing in UV disinfection creates unexposed, and thus, untreated zones.
For an example of shadowing, think of a UV emitter on one side of a hospital bed. Anything on the far side of the bed — such as a table, control panel, etc. — will not receive any of the UV light, as it is being blocked, or shadowed, by the bed itself.
The ramifications of shadowing from UV robots are notably serious. Shadowing undermines the overall effectiveness of UV disinfection, thus posing potential health risks. The surviving pathogens in shadowed areas can continue to multiply, endangering individuals in environments assumed to be safe after UV treatment.
The Problem with Stationary UV Emitters
Shadowing is a significant problem for stationary UV disinfection options. A 2023 study by Cambridge University comparing stationary emitters and autonomous UV robots in hospitals demonstrated this point. They found that out of 30 surfaces targeted by a stationary UV emitter, 8 of them were subject to shadowing. That means more than a quarter of the surfaces weren’t fully cleaned and could still harbor pathogens primed for infecting patients and staff.

The only method for solving this shadowing issue is to manually move the UV emitter around multiple times in an attempt to cover all angles. That’s a time-consuming process and is dependent on proper placement by the person operating the device. So, shadowing doesn’t just limit the effectiveness of UV emitters, it also increases the time and effort required to use them effectively.
Autonomous UV Robots Can Combat Shadowing
The critical problem of shadowing can be greatly mitigated by the innovative technology brought to us by autonomous UV robots like OhmniClean. Its unique features address the shadowing problem head-on to provide the most thorough disinfection available.
First and foremost, OhmniClean’s autonomous mobility is a game-changer. By driving itself around the room, OhmniClean actively targets every surface, navigating around objects and reaching spots that would otherwise be shadowed, ensuring that the UV light makes contact with every possible contaminant.>
Additionally, OhmniClean’s easy adaptability allows it to be swiftly integrated into a multitude of environments and routines, increasing its user-friendliness and expediting the disinfection process. By leveraging these features, OhmniClean UV robots deliver comprehensive, effective cleaning beyond the reach of traditional, stationary UV systems, thus solving the shadowing issue.
Conclusion — UV Robots like OhmniClean Deliver Thorough Disinfection
The problem of shadowing presents a challenge to the efficiency of stationary UV disinfection methods, leaving surfaces potentially contaminated and posing health risks. This issue, however, finds a formidable solution in autonomous UV robots like OhmniClean. Its mobility and adaptability eliminate shadowed areas and ensure a more comprehensive disinfection, protecting staff and patients so they can better provide and receive the care they need.
