Real-World L3 Deployments

We have deployed the CenoBots L3 across Minnesota, Wisconsin, and Iowa. Here are three customer profiles that illustrate when the L3 is the right choice over the larger L4 or L50 models.

Pharmacy Chain — Twin Cities Metro

• 7,500 sq ft sales floor, 15,000 sq ft total with back-of-house
• Narrow 30-inch aisles, high customer density, floor cleaned nightly
• Previous manual scrubbing: 1.5 hours per night, $17/hr labor + turnover
• L3 deployment: robot scrubs from 11 PM to 12:30 AM unattended
• Payback: 16 months, annual savings $9,200, no staff hired for 2-year period

Medical Office Building — Rochester, MN

• 18,000 sq ft across two floors, narrow corridors between exam rooms
• Needed daytime cleaning with minimal patient disruption
• L3 runs during lunch break (12 PM – 1:30 PM) at low speed, quiet 60 dB
• Floors consistently cleaner compared to prior contract janitorial service
• Cost: $27,500 upfront vs $22,000 annual contract service — broke even in 16 months

Boutique Retail — Des Moines, IA

• 12,000 sq ft sales floor, specialty retail, polished concrete floors
• Open Thursday–Sunday, deep-cleaned Monday–Wednesday
• L3 programmed for Monday/Wednesday 6 AM runs, no staff needed on-site
• RFM remote monitoring alerts owner of any faults via SMS
• Owner reports: "Floors look better than when I paid someone $650/month to come in twice a week."

These examples show the L3 sweet spot: small to mid-size facilities under 35,000 sq ft, tight budgets, and locations where hiring or retaining custodial staff is difficult.

CenoBots L3 for Small Business and Franchise Operations

Franchise operators — Anytime Fitness, H&R Block, dental groups, quick-service restaurants with dining rooms — increasingly deploy the CenoBots L3 as a standard operating cost line item. At $24,000 or $1,200/month on RaaS, it costs less than one part-time custodian but delivers consistent daily cleaning across multiple franchise locations. One Wisconsin dental group with four clinics deployed an L3 at each site in 2025 and reported 35% lower total custodial cost compared to contracting individual janitorial service for each clinic.

Limitations

• Not suited for facilities above 35,000 sq ft without multiple charge cycles
• Dry debris requires pre-sweep — wet scrubber only
• Hard floor only — no carpet, restrooms, or stairwells
• Floor drain and 120V outlet required for WS3 workstation
