A defensible three-step shortlist

Measure the route

Separate cleanable floor area from total building area. Record frequency, floor type, clearances, utilities, traffic, and manual-only tasks.

Match the cleaning job

Choose wet scrubbing, dry sweeping, carpet care, or a paired workflow. Size from qualified planning rates—not brochure maximums alone.

Pilot and price the system

Run finalists on the same representative route. Compare complete proposals including station, deployment, service, consumables, site work, and exclusions.

Start with comparable facts

Model sizing at a glance

Real-world expectations are planning inputs, not guaranteed outputs. Manufacturer figures are theoretical maximums. S5 and S76 have no published RFM field range, so a route study or pilot is required before capacity or ROI sizing. Product and workstation values come from the canonical product data and OEM sheets described in source 4 and source 5.

Commercial cleaning robot sizing comparison for L3, L4, L50, SP50, S5, and S76
Model	Cleaning job and route fit	Width and clearance	Planning rate	Manufacturer / OEM rate	Station and operating conditions
L3In stock	Wet scrubbing. Compact hard-floor routes, tighter aisles, and smaller zones. Validate turns, doors, floor transitions, and refill access on site.	15.7 in / 400 mm cleaning width; 27.6 in / 700 mm minimum	4,800–7,200 ft²/hr RFM-derived real-world planning expectation.

L3 accuracy note

Sproutmation has not deployed an L3. The L3 planning range above is not presented as an L3 customer outcome, deployment, testimonial, or field result. Validate L3 capacity on the buyer's own route.

Facility-type fit

Use facility type to define the test—not declare a winner

A facility label cannot prove model fit. The route, floor type, clearances, cleaning job, utilities, recovery process, and approved operating windows decide.

Healthcare and senior living

Candidate path: L3 or L4 for compact scrub routes; L50 for larger corridors and campuses; S76 where carpet care is in scope.

Validate: Infection-control process, occupied-hour acceptance, sound acceptance, doorway and equipment clearance, utilities, elevators, and recovery response.

Education

Candidate path: L4 or L50 for recurring hard-floor routes; L3 for compact candidates; SP50 or S5 for dry debris; S76 for carpet routes.

Validate: Bell/event schedules, seasonal clutter, floor transitions, gyms, elevators, overnight access, and custodial response ownership.

Retail and hospitality

Candidate path: L3/L4 for tighter public hard floors, L50 for larger open zones, SP50 for dry sweeping, and S76 for carpet programs.

Validate: Guest/customer traffic, displays and carts, food debris, floor transitions, cleaning windows, and docking utility location.

Warehouse and industrial

Candidate path: S5 or SP50 for dry debris; L50 or L4 for a separate wet-scrub pass after the debris profile is controlled.

Validate: Dust classification, debris size, forklifts and pallets, aisle widths, slopes, drainage, traffic windows, and required safety review.

Transparent ROI math

One worked L4 planning example

This example uses the current BLS national median as a public benchmark, a visible labor-load assumption, the L4 RFM weighted planning rate, one compatible CWS-01, and an annual consumables allowance. Replace every input with site-specific facts.

Published inputs

BLS base wage benchmark: $17.71/hr (May 2025 national median, source 1)
Benefits and labor load: 30% planning assumption
Current floor-care labor: 40 hours/week
Addressable share: 50%—hours that may be reassigned, not eliminated jobs
Cleanable area and frequency: 35,000 ft² × 5/week = 175,000 ft²/week
L4 planning capacity: 6,222 ft²/hr × 30 scheduled hours = 186,660 ft²/week
Equipment: $35,833 L4 + $4,667 CWS-01 = $40,500
Annual consumables allowance: $2,400 per robot

Calculation

1. Loaded hourly rate: $17.71 × (1 + 30%) = $23.02/hr.
2. Addressable hours: 40 hrs/week × 50% × 52 = 1,040 hrs/year.
3. Gross modeled capacity value: 1,040 × $23.02 = $23,944/year.
4. Net annual planning value: $23,944 − $2,400 = $21,544/year.
5. Simple payback: $40,500 ÷ $21,544 × 12 = 22.6 months.

Capacity check: the 175,000 ft² weekly plan is below the 186,660 ft² modeled weekly capacity. If a selected fleet cannot cover the entered work, reduce the addressable value by the capacity coverage percentage.

Why ISSA is cited but not substituted for robot telemetry

ISSA recommends workloading by task and production rate, and notes that site variables matter; it treats published times as benchmarks and encourages building-specific studies. This guide follows that method, then uses qualified RFM planning expectations for models that have them. It does not turn an ISSA benchmark or OEM maximum into a promised field result. See sources 2 and 3.

Planning example only—not a quote, guarantee, staffing recommendation, financing offer, or promise of payroll reduction. Use your actual wages, labor load, task hours, consumable usage, route results, utilities, site work, taxes, service scope, and financing terms. Hours identified as addressable may be reassigned to higher-value work. Actual results vary with route complexity, aisle width, obstacles, traffic, turns, edge work, floor layout, water flow, and approved cleaning windows.

Annual consumables

Budget $2,400 per robot per year

This is a Sproutmation planning allowance—not a fixed price, supplier cost, or quote. It keeps consumables visible in ROI instead of pretending ongoing operating cost is zero.

What to validate in the proposal

Pads, brushes, squeegees, filters, dust bags, and other model-specific wear items
Cleaning chemistry, dilution, water quality, carpet chemistry, and local procurement
Replacement frequency based on floor texture, debris, route hours, and care practices
Freight, tax, storage, on-site inventory, and emergency replacement stock

RaaS, Cenoflex, and purchase all leave consumables customer-purchased unless a final signed proposal explicitly says otherwise.

Commercial structure

RaaS vs. Cenoflex vs. purchase

Do not compare monthly numbers without comparing ownership, term, service, station, and exclusions. The signed proposal and agreement control.

Purchase

Ownership: Customer owns the equipment.

Payment: Published starting purchase price is a planning anchor; compatible stations, options, tax, site work, and final deployment scope are separate unless the quote says otherwise.

Service: Confirm warranty, preventive maintenance, software, support, and deployment scope in the final quote.

RaaS

Ownership: Sproutmation retains ownership during the published 24-month term.

Payment: Robot-only monthly anchor plus a separately named station add-on when required. Qualification and the final agreement control.

Service: Robot, deployment, training, preventive maintenance, parts, labor, fleet software, and support are included. Consumables are customer-purchased.

Cenoflex

Ownership: Lease-to-own structure.

Payment: Payment varies by term and credit qualification; final rate, payment, equipment, and options are confirmed in the proposal.

Service: Extended warranty and preventive maintenance are not included. Confirm deployment, software, and support scope separately.

Deployment checklist

Prove the operating model before approval

1Measure cleanable hard-floor and carpet area by route—not total building area—and record cleaning frequency.
2Map the actual job: wet scrubbing, dry sweeping, carpet cleaning, edge work, spill response, restrooms, stairs, and manual-only zones.
3Measure doors, aisles, turn zones, ramps, thresholds, elevators, and the route to the dock or service area.
4Choose a compatible workstation or dock, then validate electrical, fresh-water, drain, detergent, ventilation, and physical-clearance requirements.
5Define approved cleaning windows, floor-preparation standards, alert ownership, route recovery, escalation, and who restarts interrupted work.
6Pilot finalists on the same representative route and compare completed area, elapsed cleaning time, route coverage, interventions, quality, and staff workflow.
7Compare complete proposals: robot, workstation, deployment, training, software, service, warranty, consumables, site work, tax, financing, and exclusions.
8Set a 30-, 60-, and 90-day review using completed missions and observed route results rather than brochure maximums.

The additive-capacity test

With the compatible workstation, required site utilities, route recovery, and proper scheduling, autonomous robots can add overnight, weekend, and holiday cleaning capacity while staff are elsewhere or off shift. That additive capacity can be valuable even when no position is eliminated. It is not uninterrupted 24/7 operation, and it depends on the conditions above.
