How a Denver-Area High School Freed 5+ Custodial Hours Nightly With a Compact Scrubber
A large urban high school deployed a compact autonomous scrubber that cleaned 55,000 square feet in a school day while cutting nightly hard-floor labor by more than five hours.

Hard floors ate the night shift
This Denver metro high school keeps long corridors and commons polished while students move through the building all day. Custodial leads needed more time for classrooms, restrooms, and touch points without adding headcount.
Manual scrubbing on hard floors could consume most of a shift. Leadership wanted occupied-building cleaning that still left hours for detail work before the next morning.
- Seven hour manual scrub cycles on hard floors
- Limited staff for high touch cleaning
- Need to clean while school is in session
- Tight labor pool for overnight crews
Compact scrubber on a daily route
The district piloted a small autonomous floor scrubber sized for school aisles and commons. The unit mapped repeatable routes that could run during the instructional day while students and staff stayed in classrooms.
Supervisors reviewed daily run reports showing runtime and square footage covered. Training focused on starting missions, clearing obstacles, and redirecting staff from driving scrubbers to dust mopping and detail tasks.
- Map commons and corridor routes for occupied hours
- Pilot one building before expanding routes
- Review daily square footage and runtime logs
- Shift staff from scrubbing to classrooms and touch points

Measured time back on the floor

Published results describe the scrubber running about seven hours during a school day and successfully cleaning roughly 55,000 square feet while students were in the building.
Leaders reported hard floor work that once took about seven hours of manual scrubbing now needed roughly thirty minutes of dust mopping, a savings cited at about 5.23 hours per day that staff could spend on higher touch tasks.
What K-12 operators can copy

This account is a documented school deployment, not a Service Robot Co. customer story. It still shows how a vendor-neutral integrator should scope education scrubbers: prove one occupied route, measure square footage per day, then expand only after nightly labor hours drop.
Service Robot Co. selects compact scrubber platforms, runs site assessments, and supports commercial cleaning robot rental or lease programs with a nationwide network of regional service engineers on one contract. Phased pilots keep classes running while maps are tuned.
