Disinfection
Q: What’s the disinfection speed?
A: Up to 5000 sq feet per hour to achieve a general disinfection rate above 90%.
Q: What’s the operation time?
A: Depends on the disinfection mode, a single full charge can support operation from 3 hrs to 10 hrs. For general office hours (a.k.a. day mode), disinfectant spray solo mode is recommended, and in this mode, the robot can run for 10 hrs continuously. For after office hours (a.k.a night mode), both UV and disinfectant spray mode is recommended in controlled environment, the operation hour is 3 hrs. In a nutshell, the robot can perform 1 day mode and 2 night mode in 24 hrs (10 + 2.5 + 3 + 2.5 + 3 + 2.5 = 23.5 hrs)
Q: What kind of disinfectant is recommended?
A: In hospital environment, depends on the disinfection needs, 7.5% hydrogen peroxide (H2O2), up to 30% is recommended. In open space. Disinfectants like chelated platinum solution can be sprayed (please refer to the disinfectants supplier for the effectiveness). Please DO NOT spray toxic disinfectants like photocatalysts (sliver oxide, titanium oxide), flammable disinfectants like alcohol, aldehyde, etc). Please consult your disinfectant or environmental hygiene expert or cleaning party first.
Q: What’s the disinfectant tank size available?
A: Standard size is 1L, for 2 hrs + spray
Q: How may spray heads?

Q: Any personal protective equipment (PPE) is required to operator the ISR?
A: Yes, prolonged exposure to UVC and vaporized disinfectants is not recommended. Generally ANSI Z87.1 U6 protective goggle, UV face-shield, long sleeve clothes and trousers, and UV protection hand gloves is required. Please refer to the occupational safety guidance in your country for handling UV and disinfectants.
Q: What’s the recommended spray?
A: 7.5% hydrogen peroxide is the recommended disinfectant for enclosed hospital environment. However, in open area, it’s recommended to use non-toxic, non-alcoholic, non-skin and non-eye irritating, safe disinfectants, like plant extract based lab-certified disinfectants, e.g. AQ, BioEm, NatShield, PathAway (in alphabetical order). Some other customers also use hypochlorous acids. Our spray head can also spray other disinfectants like NaOCl, chelated platinum solution effectively. Please kindly noted that photocatalyst like sliver oxide or titanium dioxide, and other non-sprayable is not recommended to spray with our robot as they may cause potential serious side effects upon inhalation, also skin and eye irritation
Note: ISR do not limit the type of disinfectants being spray. Kindly let us know if you have other specific needs and assisted by our specialists and scientists
Q: What’s the disinfection time for 300 sq meters open space area?
A: As a general rule, each disinfection point is around 3.5-4.0m apart. The reason behind this is that the effective disinfection radius of 2.5m with an accumulated dose with 12,000μWs/cm^2 at 2mins direct irradiance. A single point disinfection area is around 12.5 sq m. An area of 300 sqm will take 24 spots of 2 mins, which is equal to 48 mins. When travelling and motion time is considered, the disinfection time to disinfect 300 sq meters is around 60 mins

Mapping
Q: Why only interactive terrestrial mapping is provided? Can you provide a fully automatic mapping like robotic vacuum cleaner.
A: Remember, the ISR is not a mini home robot. It’s gigantic indoor industrial robot and to be controlled by trained operators. ISR didn’t provide home grade bumper mode and let the robot to hit anything. Although it’s not a technical issues to open the mapping features to end-user, it’s a safety measure that we built-in to prevent mis-use of the mapping and cause any potential risks.
Q: Do you provide mapping services?
A: Yes, we provide on-site free mapping support (up to 5,000 sq ft x 10 units = 50,000 sq ft) domestically in Hong Kong. For mapping area exceeding, please kindly contact us behorehand for additional professional mapping services. We also provide free tele-mapping services for international customers.
Q: What’s the mapping speed?
A: Depends on the environment, the mapping speed varies. For large open indoor space, on average, a 5,000 sq ft space can be mapped within 30 minutes. For tele-mapping, the speed may be slower as there’s lag between robot and operator mapping console.
Q: Multiple maps for multiple locations?
A: QR code driven map changes is available.

Navigation
Q: Can I disinfect in un-mapped area?
A: Operators can use the supplied wireless controller to control the operation of the robot. But be careful, controller will 100% overtake all built-in features and must be controlled with extreme cautions by trained operators.
Q: What’s the walking speed of ISR?
A: The max walking speed is 3 m/s. However, for operation safety, it is soft limited within 1.5 m/s.
Q: Would the obstacle detection and avoidance be activated in interactive wireless control mode?
A: Obstacle detection will be performed, but avoidance will be disabled and 100% overridden by operators.Please use with extreme caution in this mode.
Q: Would a siren sound broadcast during operation?
A: Yes. By default, it’s configured for silent operation. It can be configured upon request.
Q: What will happen when the robot is out of communication range, like sudden drop in WiFi or LTE?
A: If a disinfection job is assigned to ISR, during disconnected mode, the operator console cannot access the status of the robot (since it’s totally disconnected). But log will be saved in the robot. Upon re-connection, the operator can resume the robot monitoring. In short, WiFi is only required when the user start a job. User can also approach the robot and connect in ad-hoc mode in case of total disconnection and control the robot via the ad-hoc control or with wireless controller.
