a large urban Colorado public school district with more than 200 schools and about 90,000 students
How a Major Colorado School District Scrubbed 104 Million Square Feet With Robotic Cleaners
A large Colorado district used autonomous scrubbers on halls and cafeterias, logging 8,000+ robot hours and 104M+ sq ft cleaned while staff focused on classrooms.

Staffing pressure across millions of square feet
The district operates 226 schools for about 90,000 students plus ten administrative facilities. Published figures put more than 16 million square feet of hard floor that must stay presentable for students and staff.
Like many urban districts, maintenance leaders faced a persistent custodial staffing gap. Vacant roles and tight budgets made it hard to keep hallways, gyms, and cafeterias on a reliable scrub schedule while classrooms still needed detail work.
- Large footprint with limited custodial headcount
- High-traffic corridors and food service zones
- Need for healthier learning environments without adding night shifts
Phased robot rollout on high-traffic routes
Leadership evaluated autonomous scrubbers as a way to add capacity without pretending one machine replaces a whole team. The published case describes a first wave of robotic units in late 2021, a summer 2022 expansion, and additional compact autonomous cleaners added in 2024 for a 23-unit fleet.
Units were assigned to repeatable routes in hallways, gymnasiums, and cafeterias. Custodial staff retained responsibility for setup, charging, and touch-up work while the robots handled long scrub passes during available windows.
- Pilot in late 2021 with follow-on summer expansion
- Route mapping on corridors, gyms, and cafeterias
- Staff trained as robot champions alongside existing custodial workflows
Measured floor coverage and reclaimed hours
The district reports each robotic scrubber runs autonomously about 90 minutes per day on average. Across the fleet that totals nearly 35 labor hours of autonomous cleaning every school day.
During a typical 90-minute session, a unit scrubs close to 21,000 square feet. Cumulative reporting shows more than 8,000 hours of autonomous runtime and more than 104 million square feet robotically scrubbed since deployment.
Custodial leaders describe the robots as filling a staffing gap while keeping high-traffic floors on schedule, not as a reason to cut existing team members.
What districts can expect from a vendor-neutral partner
This deployment was run by the district with equipment from a single manufacturer. Service Robot Co. did not execute this project. The story still shows what school systems gain when autonomous scrubbers are matched to the right routes and supported long term.
