Separate layer removal from substrate preservation.
Match portability to the complete site setup.
Measure accepted coverage rather than a visual pass alone.

Connect surface removal to the result the job needs

A portable pulse cleaner must suit both the layer to remove and the surface to retain. The same-looking rust or paint can differ in thickness, adhesion and composition, while the base material and next operation may allow different surface changes.

Localized removal

Define the treated region, boundaries and access. Review a representative surface rather than assuming that an easy flat patch represents edges, pits or a curved component.

Preparation for the next process

Agree the required cleanliness, profile or surface condition with the coating, bonding or inspection process owner. A bright appearance alone is not an acceptance specification.

Work at changing locations

Include power, extraction, cables, protection and setup/relocation time. A portable source is one part of the complete cleaning arrangement.

Specify the pulse system and portable support equipment

Request the exact Backpack model and technical sheet. The catalogue’s 100W label is a reference to confirm, not a cleaning-rate or runtime guarantee.

Item	Definition required in the offer
Source and output	Source/model, rated-output definition, pulse energy/duration, repetition range, beam characteristics and duty conditions.
Scan and handpiece	Fitted head/optics, qualified scan field, working/focus range, control functions and replacement references.
Portability package	Complete carried/transported mass, carrying frame or harness if supplied, operating position, cables and permitted handling conditions.
Power and cooling	Input supply, cooling/environmental requirements and exact battery option if any; runtime only under defined conditions if supported by evidence.
Extraction and residue	Capture arrangement, filtration for the assessed contamination, included accessories and residue/filter handling responsibilities.
Qualified task	Substrate/layer conditions, geometry, endpoint, inspection and demonstrated accepted coverage/time.
Site and support	Protective equipment/interfaces, area control, manuals, training, maintenance, service and delivery scope.

No verified machine weight, battery, runtime, scan width, removal speed, pulse envelope or environmental rating is established by the STR reference image. Confirm the ordered build before planning deployment.

Define an endpoint for the layer and the retained surface

Three cleaning-target reviews

Select the target to see the application evidence needed. These are evaluation tasks, not a qualified STR material list or operating recipe.

Oxide or rust on a defined substrate

Provide the base grade, corrosion condition, thickness/coverage and any pits or existing surface loss.

Agree what counts as clean: Removal and residue requirements, permitted base-surface change and the inspection or next process.
Demonstrate on representative material: Include variable corrosion and geometry; inspect the retained surface. Removing corrosion does not restore material already lost.

Unknown coatings, plated surfaces, thin sections, polished/textured finishes, nonmetallic materials and heritage objects require separate specialist assessment and sample qualification. The backpack label does not establish suitability for these surfaces.

Review pulse and scan conditions as a complete process

A pulsed source delivers energy in individual pulses while the handpiece presents it over the surface. The result depends on the layer and substrate as well as pulse characteristics, focus, scan pattern, overlap and exposure history.

Quantity / condition	What to clarify
Average output and pulse energy	Confirm both quantities and their definitions for the actual source; the wattage label alone cannot describe the energy delivered in each pulse.
Duration and repetition	Obtain available pulse functions and their qualified combinations. Do not assume that every maximum value is simultaneously usable.
Spot, focus and scan	Define the fitted optics, usable working range and scan field with the real geometry, including curved or recessed surfaces.
Overlap and repeated exposure	Review the demonstrated process and inspection endpoint, including regions that may receive more exposure during manual work.
Substrate response	Agree allowed appearance, roughness, dimensional or other changes and inspect representative samples after treatment.

Industry principle: IPG’s laser-cleaning explanation describes material-dependent removal thresholds and the need to tune pulse/spot conditions to avoid substrate damage. This is process background, not an STR test or a universal no-damage guarantee.

Qualify the unwanted layer and the material underneath

Contamination and coatings

Identify chemistry, thickness, adhesion and multiple layers where known. Provide relevant coating/material information for assessment of the process and removed matter.

Thin or finished substrates

Record wall/section, finish, texture and allowable change. Include edges, corners or features that may respond differently from a broad flat sample.

Pits and inaccessible regions

Show the real geometry and the areas that must be treated. Line-of-sight, focus and extraction access require review; a wide scan label does not prove complete coverage.

The next operation

Specify coating adhesion, bonding, welding, inspection or another required outcome. Removal of a visible layer does not automatically prove oil/salt removal, an accepted profile or downstream performance.

Plan the complete portable work arrangement

STR backpack pulse cleaning catalogue reference with portable case, connected handpiece and cable

Separate transport convenience from operating requirements

List everything that must move with the source: handpiece, delivery cable, input supply, extraction, protection and accessories. Confirm whether the ordered unit is carried while operating or positioned nearby, and whether a carrying frame or harness is included.

The photograph shows a compact case and handle. It does not demonstrate wearing the unit, cordless use, battery operation or a permissible work-at-height arrangement.

Power and location

Confirm the actual supply, connection and cooling/ambient limits. Do not plan a remote task around assumed battery power or runtime.

Reach and repositioning

Review usable delivery length, bending/handling requirements, handpiece access and cable management from the actual manual and layout.

Work duration and handling

Request complete equipment mass and ergonomics information. Include relocation, setup, inspection and breaks appropriate to the working arrangement.

Environment and access

Confirm permitted conditions for the actual equipment and site. Outdoor, confined, elevated or other constrained work needs its own access and protective assessment.

Format reference: cleanLASER’s backpack product page specifies its own carrying and power system. This illustrates why these details must be defined separately; its battery, mass, output and runtime do not describe STR equipment.

Include extraction and the removed material in the job

Laser cleaning removes material from the surface; the resulting fumes, particles and residues still need assessment and capture. Identify the layer before selecting extraction and filter handling, especially where coatings or deposits are unknown or potentially hazardous.

Capture near the cleaning area

Review source capture with the handpiece and workpiece geometry. Confirm whether extraction is integrated, separately supplied or the site’s responsibility.

Filtration and collected residue

Select suitable filtration and handling from the assessed contamination and site requirements. A process without abrasive media is not proof of no waste or no exposure.

Protection for people nearby

Plan a controlled laser work area, appropriate shielding/access controls and rated protective equipment with competent personnel. Include reflections, scan direction and surrounding access in the assessment.

Site and training

Agree electrical/environmental protection, fire precautions, extraction operation and approved procedures for the ordered system. Do not infer a protective function from the pictured housing.

Compare pulse, format and the accepted cleaning task

Reference	What it identifies	Review separately
Backpack pulse cleaning	Portable-format pulse reference in the STR menu.	Actual carrying/power package, pulse/scan conditions, endpoint, captured residues and accepted coverage.
Trolley pulse cleaning	Another pulse-cleaning equipment format in the STR range.	Mobility, source/duty, cooling, accessories and site setup; a trolley label does not establish a different cleaning result.
Continuous-wave cleaning	A different output mode in the STR cleaning range.	Heat input/exposure and substrate response for the actual task, alongside removal and throughput.
Existing cleaning route	The current method and its accepted result.	Access, preparation, setup, waste/capture, inspection and downstream acceptance under equal boundaries.

Pulse operation does not automatically make every substrate damage-free, and a higher wattage label does not establish faster accepted cleaning. Compare representative results and complete work time rather than relying on format or output mode alone.

Accept both removal and the retained surface

Define the substrate, unwanted layer, target area, treatment boundary and endpoint before the trial. Keep the actual source, optics, handpiece, extraction and demonstrated process traceable.

Check	Evidence to retain
Incoming sample	Base grade/condition, layer composition/thickness, area and representative variation, edges or recesses.
Removal result	Agreed residual-layer or cleanliness criterion and inspection method, rather than only a brighter before/after photograph.
Substrate condition	Permitted appearance, roughness, geometry, temperature-related effects or other specified changes, measured as needed.
Downstream requirement	Required coating/bonding/welding or other test where that is the task; visible cleaning alone does not prove it.
Site arrangement	Power, carrying/positioning, delivery reach, extraction, protective layout and remaining manual tasks.
Accepted coverage and time	Known area, endpoint, repeats, repositioning, setup, inspection, capture/filter tasks and interruptions under shared timing definitions.

Request a timed representative surface trial

Record area and starting condition with the agreed endpoint and retained-surface inspection. An isolated pass, catalogue photograph or supplier-wide speed figure is not a measured STR result for your task.

Maintain the handpiece, delivery and capture system

Optics and handpiece

Use the actual manual and BOM for protective windows, optics, nozzles or other fitted parts. Follow qualified cleaning/replacement procedures rather than assuming all heads share consumables.

Delivery and portable housing

Inspect and handle the cable, connectors and carrying equipment according to the supplied instructions. Confirm storage/transport and environmental limits.

Source, cooling and supply

Follow the fitted source/cooling maintenance plan. If a battery option is actually supplied, obtain its documented charging, storage, service and replacement requirements.

Extraction and records

Maintain the assessed capture/filtration package and appropriate residue handling. Retain sample/process records and review changes to the substrate, layer, optics or endpoint.

Compare the supplied system and cost per accepted area

The offer should list the source, pulse/scan specifications, handpiece, delivery cable, carrying equipment, supply/cooling, extraction, protective interfaces, consumables, documentation, training and representative acceptance trial. Identify exclusions and site responsibilities.

Agree packing, transport, commissioning, support, spare parts, warranty conditions and delivery schedule. Compare complete task costs including setup/relocation, accepted cleaning, inspection, residue capture, filters, energy and rework. No universal square-metre rate, maintenance saving or payback follows from the Backpack 100W label.

Questions before selecting a backpack pulse cleaner

What does the STR Backpack 100W label confirm?

It is the catalogue reference shown in STR’s Pulse Laser Cleaning menu with the M15 image. Confirm the exact source, output definition, pulse/scan envelope and supplied portable package in the technical sheet.

Is the backpack cleaner battery-powered?

Battery operation is not established by the STR reference. Confirm input supply and any battery option, including documented runtime conditions, charging and service, for the actual offer.

Does pulsed cleaning guarantee no substrate damage?

No universal guarantee is established. Qualify removal and retained-surface condition on the actual substrate/layer with the offered equipment and agreed inspection.

How fast will it remove rust or paint?

Use a timed representative trial with known area, layer condition and accepted endpoint. Include repeated passes, relocation, inspection and capture tasks; catalogue wattage alone is not a cleaning-rate measurement.

Can it remove all oil, salts or coating residue?

Define the required cleanliness and test method for the next operation. A visibly clean surface does not prove every contaminant has been removed.

Are extraction and filters included?

Confirm the actual capture equipment, filtration, handpiece interfaces and handling responsibilities from the assessed layer and the itemized offer.

Can it be used outdoors or on delicate surfaces?

Review the actual environment, access, substrate and protection requirements. Portable format does not establish an outdoor rating or suitability for stone, heritage, thin or sensitive surfaces.

What should I send for a quotation?

Send substrate/grade, layer details and photographs, thickness/coverage, geometry/access, required endpoint, area/workload, next operation, power/location conditions and extraction/site requirements.
