Surfaces and Solutions: The Innovative Robots Behind UV Disinfection

Microorganisms can exist on surfaces for different lengths of time - but there are ways to deactivate them. Here is a closer look at the technology behind this. 

Survival on Surfaces

In laboratory conditions, microorganisms have been found to survive on different indoor inanimate surfaces like plastic, glass, and stainless steel, for the following durations:

Surfaces and Solutions01_-1


  • Candida albicans - 3 days (glass and stainless steel)
  • Staphylococcus aureus - 7 days (woven cotton)
  • Escherichia coli - over 60 days (stainless steel)1
  • Acinetobacter baumannii - over 4 months (PVC, ceramic, glass, rubber)


These microorganisms could potentially be long-lasting sources on environmental surfaces.  

UVD Robots for Disinfection

UVD Robots are a series of self-navigating, mobile disinfection robots. These robots can maneuver through indoor areas autonomously, requiring little to no assistance for disinfection. Equipped with UV lamps, they emit 254 nanometer (nm) Ultraviolet C (UV-C) light, a type of light known for its disinfection properties.2


The UVD Robots have 3-log to over 7-log reduction rates when it comes to individual microorganisms, including:

  • Candida species,
  • Staphylococcus aureus, andsurfaces-1
  • Escherichia coli

representing a reduction of these microorganisms in a range from 99.9% to over 99.99999%.

When combined with traditional cleaning and disinfection methods, UVD Robots offer an elevated level of hygiene to indoor areas. This means a greater reduction in these types of microorganisms – making for much cleaner environments.
