The SAFI Disinfecting Robot from Pratt Miller combines autonomous mobility, electrostatic spraying technology, and intelligent reporting to provide consistent, efficient disinfectant coverage across large commercial and public spaces.

Designed to work alongside existing facility maintenance teams, SAFI autonomously treats expansive areas and high-touch surfaces, allowing cleaning personnel to dedicate more time to detailed spaces that require hands-on attention.

SAFI uses multi-head electrostatic sprayers to create a broad, consistent spray pattern that helps disinfectant reach and coat exposed surfaces throughout a facility. Its electric autonomous platform features a 16-gallon tank capacity, extended operating time, and a compact 3-to-4-foot turning radius with zero-turn capability, allowing the robot to navigate effectively through a variety of indoor environments.

Single- and dual-battery configurations are available, along with an optional charging station for facilities requiring extended operation.

Built for Large, High-Traffic Environments

SAFI is designed for facilities where efficiently treating large spaces can be challenging and labor intensive. Applications include:

• Airports and transportation terminals
• Convention and conference centers
• Stadiums and entertainment venues
• Casinos and gaming facilities
• Hotels and resorts
• Schools and educational facilities
• Manufacturing and industrial facilities
• Large retail and big-box stores
• Cruise and transportation facilities
• Other high-traffic commercial and public spaces

The autonomous platform can address large common areas and surfaces such as school lockers, casino gaming tables, retail spaces and other frequently used areas while facility personnel concentrate on smaller or more complex spaces.

Connected Coverage Reporting

SAFI goes beyond autonomous spraying by providing facility managers with valuable operational data.

While the robot works, its onboard sensors and data analytics communicate with a web-based reporting dashboard, providing supervisors with information about where disinfectant was applied, when areas were treated, and how much disinfectant was used.

This connected reporting capability gives facility managers greater visibility into their disinfection program and provides documentation that can help organizations maintain consistent facility-cleaning procedures.

Engineered to Work Alongside Your Team

SAFI is not designed to replace professional cleaning personnel. Instead, it serves as a force multiplier.

By automating repetitive disinfection of larger spaces, SAFI allows maintenance and cleaning teams to focus their expertise on detailed cleaning, confined areas, and locations requiring human attention.

Developed by Pratt Miller Mobility, SAFI applies Pratt Miller’s decades of experience in advanced engineering, autonomous systems, robotics, and mobility technology to the challenge of maintaining large facilities efficiently and consistently.

Proven in Major Transportation Environments

SAFI has been deployed and piloted in major U.S. airport environments, including Detroit Metropolitan Airport’s McNamara Terminal and Gerald R. Ford International Airport, demonstrating how autonomous disinfection technology can complement traditional facility-maintenance operations in large, high-traffic environments.
