Why a brief, not a brochure, decides the quote you get back
Most cleaning-equipment enquiries start with a product link and end with a price. That is exactly where the mismatch begins. Two plants can both write "we need an industrial steam cleaner" and need completely different machines: one washes paint booths that must stay dry, the other washes conveyor frames where runoff can be collected and drained. A brief is the document that turns your surfaces into a machine specification. Write it before you ask for a quotation, and the answer you receive is comparable across suppliers.
1. A surface inventory, surface by surface
List every item you intend to clean, one line each, with its material and its access conditions. "Line 3 frame" is not a line item. Write the substrate (painted steel, bare steel, stainless, aluminium, powder coat, anodised), the coating condition, the seals and gaskets in the area, and whether the item is vertical, horizontal or overhead. Note the geometry that traps soil: weld seams, flanges, drain holes, ribbed panels, bolt heads, cable trays. Cleaning performance is decided at those features, not on the flat panels.
Add a photograph of each surface, taken at the distance you will actually work from, plus one close-up of the worst soiling. A vendor sizing nozzles and lance lengths needs scale in the picture.
2. What the soil is and how long it has been there
Describe the contaminant in plain words and, where relevant, how long it has been on the surface. Cutting oil and coolant residue on machine guards behave differently from baked-on grease in an exhaust duct, and differently again from dried feed dust compacted into hopper corners. State whether the soil is oily, sticky, dry, mixed, or a combination that changes between shift and shutdown. If the surface is cleaned weekly and soil has had seven days to harden, say so: dwell time changes the heat and pressure the job needs.
If a chemical is currently used and you want to reduce or drop it, state that as a requirement, not as a comment. That single sentence changes the recommended mode, nozzle set and workflow.
3. The services available at the washing point
This section is where most briefs get thin, and it is the one the vendor cannot guess. Record, for each location:
- Power: voltage available at the point, single or three phase, distance from the panel, and whether the circuit is protected for wet-area work.
- Water: whether a tap connection exists, the fitting type, and whether the supply is potable, softened or reclaimed.
- Drainage: where the runoff is allowed to go, what must be screened out, and whether the floor can get wet at all.
- Clearance: door widths, ceiling height, turning space, ramp gradient, and any area the machine must not enter.
- Distance: how far the machine must be pushed or driven from its parking spot to the farthest surface.
Where a fixed water or power point is missing, say so plainly and ask for a battery-based option instead of assuming one. For example, the fixed steam cleaning machine PowerDe HW02 is listed with a tap-water inlet (4-point internal-tooth joint, 1/2 inch) and 220 V working voltage, and its product page publishes 6 kW heating power, 160 °C steam temperature, 0.8 MPa vapour pressure and an 80 L SUS304 tank. Those published figures tell you what it needs at the point of use: a water connection and a 220 V supply. The mobile, driving-style units on the same site cover different access conditions, and their battery runtime is not published on the listing, so runtime belongs in your question, not in your assumption.
4. What must stay dry and what must not be sprayed
Name the exclusions in writing. Electrical enclosures, bearing housings, sensor connectors, brake and clutch areas, insulation, adhesive bonds, painted surfaces with existing damage, and any component whose data sheet forbids a pressure wash. Where a surface is dry-clean-only, say whether dry steam is acceptable or whether the area needs brushing and vacuuming instead. Ask the vendor to state, in the quotation, which cleaning mode they propose for each exclusion zone and why.
Where you are unsure about a coating or a seal, list it as "unverified" rather than as compatible. A supplier who can test on a hidden area will tell you; one who cannot will sell you a machine and leave you with the damage.
5. How the work is done today, and what has to change
Describe the current method, the crew size, the shift in which cleaning happens, and how long the line is allowed to be stopped. A 40-minute window and a 4-hour window lead to different equipment. Add the physical effort your people can sustain: whether an operator will walk a lance for two hours or push a machine on castors, whether they work from a platform or from the floor, and whether two people must handle one surface.
Then write the change you want. Less water. No solvent purchase. A shorter shutdown. One operator instead of two. Cleaning records your audit department will accept. Each of those is a testable requirement, and each one gives the vendor a reason to propose a specific configuration rather than a catalogue model.
6. The acceptance test you will actually run
Do not ask for a machine that "cleans well". Write the trial. Pick two or three representative surfaces, including the hardest one, and specify what passing looks like: soil removed from the seam with no re-deposition on the adjacent panel, surface dry enough to return to production within your window, no damage to the coating at the tested distance, and no water ingress at the listed exclusions. Ask to run the trial with your own surfaces, your own floor and your own crew, and insist that the trial is on the machine you will be quoted, not on a demonstration unit set up under ideal conditions.
Ask for the parameter record from the trial: mode used, nozzle type and distance, dwell time, water consumed, and what was cleaned at what position. That record becomes your training material and your maintenance baseline. It is also what makes the second quotation comparable to the first. A supplier who keeps records like these is the one to work with; for cleaning duties you may not have solved before, hardware testing and an equipment brief built around your own surfaces cost far less than a machine that cannot reach the job.
7. Spares, service and training, named in the quote
Require the quotation to list the consumable and wear items with part numbers: nozzles, hoses, seals, filters, and the accessories needed for the surfaces you listed. Ask what is stocked locally, what ships from the factory, and what the lead time is. Then ask what training comes with the machine, who delivers it, how long it takes, and whether it covers mode selection for your surfaces rather than a general demonstration. A machine sold without mode training gets used in one setting, usually the most aggressive one, and the damage shows up on your coatings.
8. What to ask the vendor to return
End the brief with the reply you want. Ask for the recommended configuration with the reasoning tied to your surface list; the services the machine requires at the point of use, checked against what you wrote in section three; the exclusions you will not be sprayed, and the mode used near them; the trial plan with your parts and your acceptance criteria; and the consumables and lead times. If two configurations both work, ask them to state the trade-off in your terms — water use, crew effort, downtime, or reach — rather than presenting one option as universally right.
Checklist to send with your enquiry
- Surface list: material, coating condition, seals present, orientation, soil traps.
- Soil description and how long it accumulates before cleaning.
- Current method, crew size, allowed downtime, and the change you want.
- Power, water, drainage and clearance at every washing point.
- Exclusions: what stays dry, and what must never be sprayed.
- Trial surfaces and written acceptance criteria.
- Consumables with part numbers, lead times, and training scope.
A brief this specific takes an afternoon. It also removes the guesswork on both sides of the enquiry, and it lets you compare two quotations on the same basis. If you want to send us the surface list and the point-of-use conditions, email sales@powerde.net and we will reply with a configuration, the services it needs, and a trial plan built on your own parts.
