200,000 Sq Ft.
Audit-Ready Every Shift.
Autonomous floor scrubbers engineered for manufacturing plants, food processing facilities, and industrial operations. Consistent cleaning with AIB/SQF/FDA-ready documentation — between shifts, after wash-down, during changeovers.
Sub-7-month payback. Local service across Minnesota, Wisconsin, and Iowa.
The Warehouse Cleaning Problem
Distribution centers run 24/7 but custodial staff don’t. Warehouse and logistics operators face 45-65% annual EVS turnover, rising labor costs ($18-28/hr loaded), and audit pressure from food safety programs (AIB, SQF, FSMA) that demand documented, consistent cleaning — not “whenever we can get to it.”
45-65% Annual Turnover
Warehouse custodial positions are hard to fill and harder to keep. Night shifts and physical demands drive constant churn.
$18-28/hr Loaded Labor
Wages, benefits, insurance, overtime — the real cost of a custodial FTE in a warehouse is 1.3-1.5× base wage.
AIB/SQF Audit Pressure
Food distribution and 3PL facilities face unannounced audits. Cleaning documentation gaps = findings = lost contracts.
Zone-by-Zone Fit Analysis
Not every square foot needs a robot. Here’s where autonomous scrubbers deliver the most value — and where humans still own the work.
| Zone | Robot Fit | Recommended | Notes |
|---|---|---|---|
| Production Floor (dry) | Excellent | L50 / L4 | Open floor, sealed concrete or epoxy — ideal for autonomous scrubbing between shifts |
| Production Floor (wet process) | Good | L50 / L4 | Standing water from wash-down; robot cleans after drain. Chemical-compatible pads required |
| Packaging & Palletizing | Excellent | L4 / L50 | High debris area (shrink wrap, cardboard dust, product spillage); daily cleaning critical |
| Raw Material Receiving | Good | L4 | Dock-adjacent area with outside debris tracking. Schedule after daily receiving window |
| Finished Goods Warehouse | Excellent | L50 | Large open area, minimal obstacles. Standard warehouse cleaning protocol |
| Corridors & Hallways | Excellent | L3 / L4 | Long runs between production areas; robots excel at repetitive corridor cleaning |
| Break Rooms & Locker Areas | Good | L3 | Food debris from meals. Clean between break periods for best results |
| Shipping & Loading Docks | Excellent | L4 / L50 | High-traffic zones; outside debris, pallet dust. Schedule when dock doors closed |
| Quality Lab & Testing Areas | Moderate | L3 | Smaller footprint with sensitive equipment. Supervised runs recommended |
| Cleanrooms / Controlled Environments | Not Appropriate | — | Classified areas require specialized protocols beyond floor scrubbing |
AIB/SQF Compliance — Built Into Every Run
Food distribution, cold chain, and 3PL facilities face unannounced audits from AIB International, SQF Institute, and FDA (21 CFR Part 117). The #1 documentation gap auditors find? Inconsistent or missing cleaning records.
Our Robot Fleet Management (RFM) platform automatically generates timestamped cleaning logs for every run. Date, time, zone, square footage, duration, coverage percentage — all digital, all searchable, all ready for your next audit.
The Audit Documentation Advantage
Manual cleaning logs rely on the custodian writing it down — correctly, consistently, every time. Robot-generated logs are automatic, tamper-proof, and never miss a shift.
Paper logs, inconsistent entries, missing shifts, handwriting auditors can’t read, no coverage verification
Automatic digital logs, exact sq ft + duration, coverage heatmaps, exportable PDF/CSV, 100% audit trail
“Show me your cleaning records for the last 90 days.” — With RFM, that takes 30 seconds, not 30 minutes.
Robot Selection by Facility Size
Warehouse square footage drives the right robot choice. Most DCs need an L50 for the main floor plus an L3 or L4 for secondary zones — dock areas, offices, break rooms.
CenoBots L3
$24,000Compact enough for tight production areas; fits 36" doors; quiet operation (<65 dB)
CenoBots L4
$35,833Most versatile; 80L tank handles shift-change cleaning of multiple zones
CenoBots L50
$41,820Largest scrubber; 120L tank; covers 25K+ sq ft/hr for maximum throughput
CenoBots SP50
$32,667Autonomous sweeper for outdoor debris, gravel, and seasonal cleanup
Scheduling Around Warehouse Operations
Warehouses don’t shut down for cleaning — but they do have predictable windows. Robot cleaning is zone-windowed: clean specific areas during their lowest-activity periods.
| Window | Zone | Robot | Notes |
|---|---|---|---|
| Shift Change (30–60 min) | Production Floor Zone A-B | 2× L50 | Between 1st/2nd or 2nd/3rd shift — floor clear of operators |
| Sanitation Window (post-washdown) | Wet Process Areas | L50 / L4 | After chemical wash-down and drain; robot removes residual water + debris |
| Overnight (10PM–6AM) | Full Facility | All | Deep clean entire plant; maximum coverage with zero production conflict |
| Weekend Maintenance | Entire Facility | All | Full facility deep clean during scheduled downtime; pair with PM activities |
| Changeover Windows | Packaging Lines | L4 | Product changeover = 30–90 min floor window; clean between SKU runs |
Forklift Safety Protocol
CenoBots robots detect forklifts via 360\u00b0 LiDAR and will stop or reroute. For optimal coverage and safety, schedule primary cleaning runs during low forklift traffic — shift changes, meal breaks, overnight. Forklift operators appreciate clean floors (better traction, fewer skid marks, improved visibility of floor markings).
ROI Model: 180,000 Sq Ft Distribution Center
A mid-size regional DC — 2 shifts, 5 days/week, sealed concrete floors. Currently staffed with 2 custodial FTEs on rotating shifts at $22/hr base ($28.60 loaded at 1.3\u00d7 multiplier).

Multi-Site Fleet Management
3PLs and regional distributors don’t operate one building — they run 5, 10, or 50. Our RFM platform gives your operations team a single dashboard across every facility.
