About Wanda SD

Wanda SD is a light-duty disinfecting robot that can be guided into a space by a Smart Device. Wanda uses UVC light (additional Ozone option also available) to disinfect everything from plants and warehouses to hotels, office buildings and airplanes. This vehicle is equipped with 42-inch tower with a singular 100-Watt UVC lamp, as well as UVC floor spotlights in the 253.7 nm range.

Specs

Sitting on a base of 17″ x 17″ with a height of 42″ allows Wanda to easily move between rooms of residential, commercial, and industrial buildings. The UVC lights break down the DNA or RNA of dangerous viruses and bacteria found in water, surfaces and air. Wanda SD sanitizes approximately 200 square feet in just 15 minutes.

In Wanda SD units that contain the Ozone addition, Ozone is dispersed when the sanitizing process begins. Ozone disinfects the areas UVC light is unable to reach.

UVC Light

Lights underneath the vehicle are used to disinfect the floor, while the light tower cover tables and other surfaces. UVC can potentially damage eyes and skin with prolonged exposure. To protect workers, the vehicle is equipped with two levels of perimeter monitoring via a Passive Infrared Sensor (PIR) and ultrasound that detect when someone enters an area being sanitized. When this occurs, the UVC lamps automatically turn off.

Highlights & Technical Specs

Wanda SD is a collaborative engineering feat that was developed to protect public spaces from viruses and bacteria.

Wanda SD features lamps on top and underneath the vehicle that emit 253.7 nm Ultraviolet-C (UVC) light that kills 99.9% of pathogens in the air and on surfaces, including two coronaviruses similar to COVID-19: SARS-CoV-1 and MERS-CoV, according to the IUVA.

Because direct prolonged exposure to UVC light can potentially damage eyes and skin, Wanda SD can be controlled from another room using nearly any smart device. It is also equipped with perimeter monitoring and ultrasonic sensors that detect when someone enters an area and automatically turns off the lights.

Wanda SD emits a verbal confirmation when disinfection of an area is complete and keeps an internal running log of where and when all tasks were finished for verification.

At just 42” tall with a 17”x17” base, Wanda SD is versatile enough to navigate through tight spaces such as hotel rooms, airplanes and offices.

An individual Wanda SD can cover up to 7,200 sq. feet over a 12-hour period before returning to its charging base.
