Cleaning-machine Sample Scoring and Sign-off Protocol

Questions this guide answers

Primary question: How should a buyer score, document and sign off a commercial cleaning-machine sample test?

Why should a commercial floor-cleaning machine be tested on the real floor, soil and route before approval?

Direct Answer

A sample should be accepted only after the exact quoted machine and configuration complete a pre-approved route on representative floor and soil, with measured cleaning, water recovery, runtime, access, service and operator results. Freeze the test method and pass boundaries before the demonstration, preserve raw failures as well as successful runs, and use critical gates rather than an average score. The signed result applies only to the tested configuration and conditions; it is not certification, a production-lot inspection or proof that another model will perform the same way.

Commercial Cleaning Equipment Sample Test Checklist

Scope and assumptions

This protocol is for distributors, importers, contractors and facility buyers evaluating a sample before purchase or batch approval. It covers identity, site fit, cleaning, residual water, loaded runtime, tank service, daily care, documents and sign-off. It does not replace conformity assessment, production-lot inspection, durability testing, floor-friction measurement or facility safety procedures. Isolate the authorised test area and use only approved routes, chemicals, charging and wastewater processes.

Write the acceptance requirement before selecting the sample

The buyer should issue a short user requirement and test plan before the sample arrives. Otherwise, a sales demonstration can produce attractive images without answering whether the machine fits the actual operation.

Requirement group	Fields to approve before testing
Intended work	Site, zones, cleanable route, frequency, shift window and reopening requirement
Access	Doorways, aisles, lifts, thresholds, turns, storage, charging, refill and drain routes
Floor and soil	Material, coating, texture, joints, current damage, target soil and loose-debris control
Cleaning process	Approved brush or pad, chemistry, dilution, passes, dwell, solution setting and pre-treatment
Recovery	Test maneuvers, observation delay, fixed-area measurement method and maximum residual-water boundary
Runtime	Required net loaded time, gross route window, reserve, charge condition and end point
Operator and service	Intended operator, daily-care steps, consumables, tools, training and document language
Decision	Critical failures, conditional items, retest method, witnesses and signing authority

Do not use total building area as the route. Exclude inaccessible spaces and separate open lanes, narrow aisles, edges and manual-only areas. Record cleaning frequency: a route cleaned twice per shift creates a different duty cycle from the same area cleaned once.

Freeze the sample identity and configuration

Photograph all nameplates and assign a test ID. The first worksheet should identify:

Brand, exact model, serial number and revision
Machine format as stated in the controlled quotation, without inference from appearance
Battery and charger manufacturer, model, chemistry, voltage and capacity where available
Brush or pad, holder, pressure/mode and condition
Squeegee assembly, blades, condition and approved adjustment
Solution and recovery settings, accessories and control/software version where shown
Tank state, hour meter, prior sample use and any repaired or replaced parts
Quote number, specification revision, manual revision and declaration/document references

If a safety-relevant or performance-relevant item changes during the trial, open a configuration-change row. Record the reason, approver and affected tests. Do not silently substitute a pad, blade, battery, charger or operating mode and continue under the original test ID.

Select representative test zones

Use the expected floor, including representative texture, joints, wear and soil within safe limits. Public-facility tests should include turns and edges that control reopening; warehouse tests should include representative aisle ends, tire marks, dust and joints. Test materially different zones separately. Do not use an empty smooth lane to represent an occupied textured route, or create an artificial failure with undocumented soil. Identify any standardized artificial soil and keep that result separate from the real-route trial.

Before-and-after photographs need fixed camera positions, lighting, scale and route markers. Photographs support traceability but are not a quantitative result unless the image method has been validated. Where the buyer requires a measured soil-removal or surface-change result, specify the instrument, calibration, sampling grid and limit in advance.

Field-level sample protocol

Run the phases in order. A failed identity, safety or access gate should stop performance testing until it is resolved.

Field ID	Test	Required record	Critical boundary
SA-01	Product identity	Quote, model, serial, revision, nameplates and configuration	Delivered sample is traceable to the quoted unit
SA-02	Compliance-document match	Declaration, instructions, labels, market and versions	No known model, entity, market or document contradiction
SA-03	Pre-use safety inspection	Controls, guards, cables, connectors, leaks, alarms and visible damage	No unsafe condition before operation
SA-04	Door and aisle access	Narrowest measured points with full supplied envelope	Unit passes without contact or unsafe improvisation
SA-05	Turn and route access	Both directions, aisle ends, thresholds and normal repositioning	Required route is completed within approved clearances
SA-06	Lift, floor and transport load	Verified operating weight and facility rating where relevant	Net weight alone is not used for load approval
SA-07	Floor compatibility	Small-area trial, surface inspection and approved chemistry	No unacceptable scratch, coating change, discoloration or damage
SA-08	Target-soil cleaning	Defined soil, process, passes and before/after measurement	Buyer-approved cleaning boundary is met
SA-09	Edge cleaning	Fixed edge route and residual soil map	Edge result meets the stated scope; manual follow-up is quantified where allowed
SA-10	Water recovery	Straight, left/right turns, edges, joints and U-turns	Every critical residual-water result meets its limit
SA-11	Reopening time	Fixed observation method and traffic-control period	Facility release rule is met before barriers are removed
SA-12	Loaded runtime	Drive/traction, brush/pad, solution and recovery active on representative route	Required work time plus reserve is achieved
SA-13	Gross route time	Cleaning plus normal refill, drain, debris and inspection stops	Route fits the operating window
SA-14	Tank cycle	Measured solution added, recovered volume and service frequency	No unplanned interruption or unsafe wastewater handling
SA-15	Operator handling	Intended operator, controls, visibility, maneuvering and emergency actions	Operator completes required tasks safely after instruction
SA-16	Daily care	Empty, rinse, clean squeegee/filter, inspect consumables and prepare for charging/storage	Required work is practical and no uncontrolled spill occurs
SA-17	Noise and environment	Site method and limit where relevant	No unverified "quiet" claim substitutes for site measurement
SA-18	Evidence and handover	Raw data, photos, manuals, parts, training and open issues	Package is complete enough to reproduce the decision

For SA-02, use the separate CE declaration model and market verification workflow. A functional sample pass cannot cure a conformity-document mismatch.

Run the cleaning phase under controlled conditions

First perform a short familiarisation run that is not scored. Then return the floor and machine to the defined starting condition. Record solution volume, chemistry and dilution; brush or pad; operating settings; operator; route; start time; passes; dwell; interruptions and environmental conditions.

Evaluate cleaning and surface condition separately: a process may remove soil while damaging a coating. Require both soil-removal and no-unacceptable-change results, following floor requirements and the chemical safety data sheet.

Repeat critical segments; straight passes do not replace turns, edges and joints. Retain failures, change one factor at a time and show the original result, correction and retest.

Test water recovery as a safety gate

Use a route containing straight pickup, left and right 90-degree turns, a representative 180-degree U-turn, both edge directions where applicable, joints and the highest-risk traffic zone. Set observation times before testing. Combine a visual trail map with fixed-area gravimetric blotting when a quantitative boundary is required.

Averages do not override a wet tail or pool. Apply the limit to every critical sample and repeat. Keep barriers and warning controls in place until the facility's release rule is met. The detailed method is in the turn, edge and U-turn water-recovery protocol.

Test runtime as a route result

Charge the documented battery with the documented approved charger to the defined full condition. Run the required machine systems on the representative route and keep separate net loaded and gross route clocks. Log battery indications, completed work, turns, solution use, recovered water, refill/drain stops, alarms and any decline in cleaning or recovery.

For this buyer-defined protocol, use two valid runs when practical and assess the lower result against the required work block and reserve. A different pre-agreed run count is valid when the buyer records the reason and acceptance method. Do not extrapolate from a dashboard percentage or call a no-load drive test representative. The full-system loaded runtime protocol provides the field sheet and calculations.

Use critical gates, not a blended score

Decision	Required logic	Sign-off consequence
Pass	Every critical identity, safety, access, floor, cleaning, recovery, runtime and document gate passes; required evidence is complete; only stated noncritical observations remain	Approve the exact tested configuration for the stated conditions
Conditional pass	All safety-critical and performance-critical gates pass, but a limited noncritical item has a named owner, objective closure evidence, deadline and affected retest scope	No automatic batch release; close conditions in writing before the defined approval gate
Fail	Any critical gate fails, an unsafe condition occurs, the route or floor is not representative, required performance is missed, a compliance contradiction remains, or a condition cannot be objectively closed	Reject the tested configuration or correct and repeat the defined tests
Invalid - no decision	Identity, method, instrument, route or configuration control is lost	Repeat from a valid controlled starting point

Conditional pass must not be used for residual water above the safety limit, floor damage, unresolved compliance scope, unsafe charging or a machine that cannot complete the required route. Those are failures until corrected and successfully retested.

Illustrative decision example

This example is illustrative only and is not an ELEREIN result.

A sample passes 17 of 18 worksheet rows but leaves one U-turn sample above the buyer's residual-water maximum. The overall decision is fail, not 94% pass and not conditional pass. After a documented squeegee correction, the buyer repeats SA-10 on all required maneuvers and rechecks the straight baseline. Only a complete passing retest can close that critical gate.

Connect sample approval to production control

The signed sample should become a controlled reference sample only when the contract identifies its model, serial number, configuration, photographs, approved deviations and document revision. Batch units should be checked against that frozen reference through a separate production and pre-shipment inspection plan.

ELEREIN's confirmed commercial baselines are MOQ 10 units, a 7-day sample cycle and a 15-day batch-production cycle after required details and approvals. These are planning baselines subject to configuration, payment, stock, region, order quantity, approval gates and final contract; they are not unconditional delivery promises. Define when each clock starts and whether packing, inspection, transport and customs time are included.

Customization may cover logo, color, packaging, manual language, configuration and accessory combinations, with no new mold opening, all subject to final engineering review and contract. Cosmetic changes still require label and document review. Configuration or accessory changes require an impact assessment and repetition of every affected acceptance test; a sample approval does not automatically transfer to a changed production BOM.

ELEREIN product-data connection

Use these confirmed facts to shortlist and identify a sample. None of them proves route completion, operating weight, floor compatibility, water recovery or loaded runtime.

Model	Cleaning/squeegee width	Solution/recovery tanks	Published baseline runtime	Dimensions; net weight	Route-area screening reference
E60	510/750 mm	50/60 L	4-5 h	1380 x 600 x 1200 mm; 188 kg net	Up to 10,000 m2 under confirmed route conditions
E100	760/1000 mm	90/100 L	5-6 h	1650 x 900 x 1300 mm; 422 kg net	Up to 20,000 m2 under confirmed route conditions
E130	860/1000 mm	120/130 L	6-8 h	1720 x 1010 x 1430 mm; 530 kg net	Up to 25,000 m2 under confirmed route conditions

The area values are screening references, not productivity or shift guarantees. Runtime ranges are published baselines, not full-load test results. Dimensions do not replace measurement of the supplied working envelope, and net weight is not operating weight. E60 is a walk-behind floor scrubber and E100/E130 are ride-on floor scrubbers; the sample record must still identify the exact tested configuration.

Limitations

A sample result is a snapshot of one unit, route, operator, floor, soil, chemistry and date. It does not prove production consistency, durability, battery cycle life, every accessory combination or performance on another site. A short demonstration should be followed by risk-based production inspection, incoming inspection and longer operational monitoring where the purchase scale warrants it.

External manufacturer and laboratory guidance can help define fields and methods, but competitor data must never be presented as ELEREIN performance. Publish an ELEREIN measured result only with the actual dated record, exact configuration, conditions, raw method, limitations and approval to disclose it.
