Will there be a dedicated account manager or implementation support?

Yes, upon purchase every facility will be assigned a dedicated Solutions Engineer to act as a point of contact and resource for all training and technical support. OhmniLabs will proactively monitor your device(s) health to ensure maximum uptime for your facility.

Where is OhmniClean made?

OhmniClean is proudly made in America: all units are manufactured at OhmniLabs’ California headquarters. Support and customer service teams are entirely North America-based.

Why choose an autonomous UV system over alternative solutions, such as stationary UV emitters?

The inverse square law dictates that the power of light decreases the further a surface is away from the light source. In addition, light is a line-of-sight natural phenomenon; if there is an object between a surface and a light source, light will not reach the surface due to shadowing.

Due to the inverse square law and shadowing, stationary UV emitters require operators to adjust the position of emitters repeatedly and perform numerous disinfection cycles to provide adequate UV light coverage. This will lead to not just substantial labor and time consumption but also a poor application of UV light as surfaces will certainly be missed due to shadowing.

OhmniClean is a robotic device that is engineered to autonomously navigate as close as possible to high-touch surfaces to disable microorganisms using UV-C light with high precision and intensity. OhmniClean has autonomously disinfected millions of square feet of hospital spaces since its release.


Does OhmniClean need to be plugged in when in use?

Unlike stationary emitters, OhmniClean is fully battery-powered. Each purchase of OhmniClean includes 2 hot-swappable power stations. One power station will provide 75 minutes of disinfection and charge to full in 60 minutes. As a result, OhmniClean is capable of 24/7 disinfection.

Is there a log where I can run reports on the rooms?

Yes, OhmniClean is built with state-of-the-art reporting systems. You can instantly view disinfection reports for any room directly on the robot’s screen. You can also view data across an entire fleet of OhmniClean robots with our included web reporting system. All data is real time and instantly accessible.

Can the disinfection report be added to electronic medical records?

Yes, we can integrate with hospital systems. We can offer EMR Integration Services where the fee is based on the scope of integration.

Can you take off the light module?

Yes! You can simply unplug it from the robot and lift it off. This makes it easy to transport or ship.


What is the footprint of OhmniClean? Can it navigate small rooms?

Yes, OhmniClean can autonomously navigate within small rooms and confined spaces. With a footprint of 14” W x 18” L x 71” H, OhmniClean is the most compact, nimble, and portable UV disinfection solution available.

How long do the bulbs last?

OhmniClean’s bulbs are rated for 9000 hours. New bulbs are provided every year (or when needed) as part of warranty.

Does it take special knowledge or certification to remove or handle the bulbs?

No, these Philips bulbs are available at stores and require no special knowledge or certification to handle, aside from just being careful with them. The modern UV-C bulbs have a minute amount of mercury and the actual guidance from Philips is to simply wear gloves when cleaning up the pieces and to ventilate the area for 30 minutes.

How many degrees does the UV cover?

We focus the UV light in a 300 degree arc concentrated on the front and sides of the bot. This is done for maximum efficiency, since OhmniClean is autonomous. Unlike a stationary unit, you’re moving around and as close to objects as possible, so we’re taking all the wasted UV energy going to where the robot just came from and spreading that to the sides and front where it’s needed most.

What is the exact nm wavelength generated by the bulbs?

253.7 nm

How many bulbs are in the light module?

8 bulbs

How much do the bulbs cost to replace?

About $60 per bulb. OhmniClean was built for easy maintenance – you can replace them yourself in about 5 minutes.

Using OhmniClean

How do I disinfect the OhmniClean robot?

OhmniClean can be sanitized using commonly found hospital wipes such as Oxivir TB.

How fast does OhmniClean disinfect a typical room?

OhmniClean is capable of disinfecting a typical room in less than 7 minutes to achieve log 4 reduction of most pathogens. Like all other UV disinfection systems, more time may be required for disinfecting tougher pathogens such as C. Diff.

What is the maximum square footage can OhmniClean disinfect?

OhmniClean can disinfect spaces of any size. Operators have disinfected spaces as large as 4500 square feet, enabled by OhmniClean’s cordless use and swappable battery technology.

Can OhmniClean traverse over floor transitions?

Yes, OhmniClean is capable of traversing over floor transitions, including those commonly found in patient rooms with bathrooms.

How soon after disinfecting is the room available?

The room is safe to enter immediately after cleaning finishes. No harmful gasses or substances are produced during disinfection.

Does OhmniClean require specialized knowledge to operate?

OhmniClean is the most user-friendly and easy-to-learn product on the market. A typical operator can be trained in as little as 15 minutes. Your dedicated OhmniClean Solution Engineer will provide hands-on training and work with your facility to design the best process for your team.

Do you need to do a regular cleaning of a room before sending in the robot?

Yes and no. Layers of dirt or grime can protect the organisms from UV-C exposure and reduce effectiveness. We always recommend that disinfection follows regular (non-disinfecting) cleaning for maximum efficacy, though there are still benefits to disinfecting when you don’t have a chance to clean first.

UV Disinfection

Can UV disinfection’s efficacy be verified?

Yes, UV disinfection efficacy can be evaluated through a range of methods, such as dosimeter testing and microbiology testing. Each method offers distinct advantages tailored to specific requirements and testing frequencies.

OhmniClean’s efficacy has been rigorously tested and validated by laboratories and in peer-reviewed publications.

What type of microorganisms (bacteria, viruses, spores, molds etc.) is UV-C effective against?

Ultraviolet light has been widely acknowledged for its efficacy in combating various microorganisms. Its ability to target viruses (e.g. SARS-CoV-2, influenza, norovirus), bacteria (e.g. E. Coli, MRSA), fungi (e.g. Candida, Aspergillus), and even spores (e.g. C. Diff) stems from their susceptibility to irradiation due to the presence of RNA or DNA. UV disinfection has been extensively researched, yielding valuable insights into the required dosages for inactivating different types of microorganisms. Generally, bacteria are more readily inactivated compared to viruses, while fungi and spores require longer and more proximal exposure.

How does UV-C disinfection work?

  • Ultraviolet (UV) light exists within the spectrum of light between 10 and 400 nm. The germicidal range of UV is within the 100-280nm wavelengths, known as UV-C, with the peak wavelength for germicidal activity being 265 nm.
  • UV light is absorbed by the DNA and RNA of microorganisms, which causes changes in the DNA and RNA structure, rendering the microorganisms incapable of replicating. A cell that can’t reproduce is considered dead; since it is unable to multiply to infectious numbers within a host.
  • Peak germicidal activity in the UV spectrum occurs within 200-280nm, also known as UV-C. Unlike UV-A and UV-B, UV-C does not penetrate glass, which poses a safety hazard to operators and patients. 253.7 nm (254nm) is the optimal choice of wavelength for UV light as it is the closest to the peak germicidal wavelength of 265nm.

What about degradation during terminal cleaning? On the surface of equipment, etc?

Bleach and other disinfectants are often much harsher and cause corrosion over time and residue on the surface of the equipment.

Any issues with fabrics fading? Or artwork?

Materials that are robust to sunlight exposure will generally be robust against UV-C exposure as well. If the artwork is expensive, we would suggest caution. But note that even a thin layer of glass or acrylic stops virtually all UV-C (unlike UV-A or UV-B in sunlight), so if the artwork is behind something transparent it should be safe.

Will it damage paint? Will it damage soft materials?

UV exposure of any kind (sunlight or artificial sources) will affect different materials differently. OhmniClean’s UV exposure level is specifically targeted to be powerful enough for fast cleaning but not excessively powerful to damage the environment.
