Aspirus Health
Automated cleaning logs, consistent path execution, and overnight operation across a multi-site health system.
What Aspirus Health Was Facing
- JCAHO compliance requires documented proof that every zone is cleaned on schedule — manual logs were unreliable and time-consuming
- Overnight hospital corridors need consistent cleaning without disrupting patients or medical staff
- Infection control pressure demands repeatable, verifiable cleaning coverage — missed zones are unacceptable
- EVS labor costs of $30–35/hr loaded make manual corridor scrubbing the largest line item in facility maintenance budgets
- Multi-site expansion means the same staffing challenges repeat at every new facility
How We Solved It
CenoBots L50 handles large-footprint facilities (lobbies, main corridors, cafeterias) while L3 units cover wings, patient corridors, and specialty areas. Both run overnight with full autonomous navigation.
- L50 deployed for high-volume areas — emergency department corridors, main lobbies, cafeterias
- L3 units cover patient wings, specialty corridors, and connector hallways
- Every session generates timestamped cleaning logs with coverage area, distance traveled, and zone completion
- Quiet ≤64 dB(A) operation allows overnight runs without patient complaints
- Retained EVS FTEs redirected to restrooms, elevators, isolation rooms, and other areas requiring manual attention
Measured Outcomes

Deployment Notes
- Multi-site deployment across Wisconsin Aspirus facilities
- L50 for facilities over 100,000 sq ft; L3 for wings and corridors under 50,000 sq ft
- Night shift autonomous operation — robots start after patient traffic drops
- WS3 workstations enable continuous operation without manual intervention
- Fleet management software provides centralized monitoring across all sites
Operations Summary
Deployment operations report: Autonomous scrubbers now handle 100% of corridor and common-area floor cleaning during overnight shifts. EVS staff have been reassigned to high-touch surfaces, restrooms, and isolation rooms — areas where manual attention is required. Cleaning session logs are exported directly to the compliance documentation system, eliminating manual log entry. Zone coverage consistency has improved measurably compared to prior manual-only operation.
Healthcare is the highest-value segment for autonomous cleaning. Aspirus is actively expanding to new sites, and each new facility follows the same deployment pattern — making this a repeatable, scalable reference for any hospital or health system evaluating cleaning automation.
