University of Minnesota
Evening and weekend autonomous runs across campus buildings — zero overtime, full coverage.
What University of Minnesota Was Facing
- Large campus buildings with diverse floor plans — gyms, corridors, cafeterias, lecture halls
- Tight custodial budgets cannot support overtime for evening and weekend cleaning shifts
- Coverage gaps during non-business hours lead to inconsistent floor quality across campus
- Staff shortages make it difficult to maintain cleaning standards across all buildings simultaneously
- Multiple buildings require coordinated fleet management to track coverage and uptime
How We Solved It
A mixed fleet of L50, L4, and L3 robots covers buildings of varying sizes. L50 handles the largest footprints (gyms, event spaces), L4 covers mid-size common areas, and L3 units handle corridors and smaller buildings.
- L50 deployed in large-footprint buildings — gymnasiums, recreation centers, and event spaces
- L4 units cover dining halls, student unions, and mid-size common areas
- L3 robots handle corridor networks and smaller academic buildings
- Evening and weekend autonomous runs eliminate overtime costs entirely
- Custodial staff redirected from repetitive scrubbing to detail cleaning, restrooms, and event prep

Deployment Notes
- Mixed fleet deployed across Twin Cities campus buildings
- L50 for buildings over 50,000 sq ft; L4 for 20,000–50,000 sq ft; L3 for under 20,000 sq ft
- Evening autonomous operation (typically 6 PM – 6 AM) plus weekend daytime runs
- Fleet management software tracks coverage, uptime, and battery status across all campus robots
- Quick stop-and-restart capability accommodates campus events and scheduling changes
Operations Summary
Deployment operations report: Campus custodial operations now run autonomous floor scrubbing across multiple buildings during evenings and weekends. Overtime costs have been eliminated for floor scrubbing tasks. Fleet management provides centralized visibility into robot status, coverage data, and maintenance needs across the campus. Custodial staff report improved job satisfaction from reduced repetitive physical labor.
The University of Minnesota is a flagship higher education reference. A successful deployment at one of the largest public universities in the country opens doors to every college and university in Minnesota — and demonstrates that autonomous cleaning scales across diverse building types on a single campus.
