Hospital Consult Room Disinfection Spraying

XDBOT

eXtreme Disinfection roBOT (XDBOT) is designed for a situations that requires regular disinfection everywhere.

Removes need for cleaners to be in contact with surfaces, thereby reducing the risk of picking up the virus from potentially contaminated areas
Addresses the current manpower crunch in the sanitation industry

ELECTROSTATIC SPRAY

Aside from conventional pressure-spray nozzle, XDBot has electrostatic-charged nozzle to ensure a wider and further spread of the disinfectant, behind and over hidden surfaces. An electrostatic nozzle discharges disinfectant droplets with a positive electrical charge. These droplets will then be attracted to the negatively-charged surfaces. Surfaces already covered with the disinfectant will then repel the spray (positive repels positive) so that these droplets seek out surfaces with no disinfectant yet, making this method very efficient.

FAQ

Q. What kind of disinfectants are suitable for XDBot?

A. XDBot can take in almost any disinfectant. That said, the 2 most commonly used ones are (1) chlorine-based and (2) quaternary ammonium compounds or quats or QAC. Another suitable one is hydrogen peroxide although some formulation may require a specially designed sprayer and nozzle.

Chlorine-based disinfectants can be prepared from various starting materials such as household bleach or NADCC tablets. QAC are usually purchased in the exact needed concentration or in concentrated form for further dilution.

The final choice of disinfectant to use with XDBot depends on the client's requirements (use case), applicable health and safety guidelines, and chemical manufacturer's guidelines.

CDC has good overview on different types of disinfectants, most of which, aside from the 3 mentioned above, may not be suitable for use in XDBot or sprayers in general. For example, alcohol is flammable (not suitable for electrostatic sprayer) or formaldehyde is highly toxic. Link is here: <CDC Guidelines on Disinfection Chemicals>

Q. Where can I find a list of chemicals approved for use against COVID-19 virus?

A. The Environmental Protection Agency (EPA) of US publishes and updates its approved list of chemicals. You may access it here: <List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19)>

Q. How do we go about cleaning our facilities or spaces to ensure safety from COVID-19?

A. The National Environmental Agency (NEA) Singapore has a guideline on disinfecting possible COVID exposed facilities and other scenarios. Links are here:

Q. Can XDBot do spraying without electrostatic?

A. Yes. The electrostatic functionality can be turned on or off.

Q. Does XDBot require to connect to my internal network or any network for that matter?

A. This depends on how many XDBots you want to deploy and how. As it is, each robot has its own connectivity but it does not need to connect to any network at your site to operate. If there are multiple XDBots, the robots can connect to each other if they are within range. The robots can also tap into your network in the premises, use mobile connection (4G/LTE) or tap into a separately installed network.
