Start with the equipment being cleaned, not the cleaning machine
List every item in the cleaning scope as your maintenance team names it: machining centres, conveyor frames, mixers, filling heads, hoppers, exhaust hoods, trolleys. For each one note dimensions, the material of the surface (painted steel, stainless, anodised aluminium, plastic guards), and what is sensitive — bearings, electrical encoders, belts, pneumatic seals, open wiring, bearings that must not be flooded.
State clearly whether the equipment is cleaned in place or removed to a wash area. In-place cleaning is the harder case: the vendor needs to know that run-off has somewhere to go, and that nearby electrical panels will be covered or isolated.
Describe the soil the way the floor describes it
"Dirty" tells a vendor nothing. Write what the deposit is: cutting oil and swarf, drawing compound, graphite lubricant, flour dust, sugar residue, protein film, carbonised grease on a hood, or road grime on a chassis. Say how old it is — wiped daily, or built up over months. Note whether it is cold and hard or warm and soft, and whether water-soluble or not.
This is the single most influential part of the brief. Hard, polymerised grease and cutting-fluid residue respond to high-temperature steam and pressure; loose dust does not need either. If the vendor sees light dust, they should recommend the smaller machine — and you should be comfortable hearing that.
Give the cleaning window and the frequency
How long is the line actually stopped for cleaning — 30 minutes between shifts, a Saturday morning, a two-week shutdown? How many units per cycle, and how many shifts per day will a machine be used? A machine that is fine for one operator on a weekly clean may be the wrong choice for four operators on a daily clean.
Include who will operate it. If cleaning is done by maintenance staff who also run other duties, ask the vendor to keep the control set simple and the consumables standard. If it is a dedicated cleaning crew, more modes and more accessories are usually worth having.
Document utilities where the cleaning actually happens
This is the section buyers most often leave out, and the section vendors most often have to chase. For each cleaning location, record:
- Power: outlet type, voltage available at that point, and the distance from the outlet to the machine. Fixed units such as the PowerDe HW02 steam cleaner are listed at 220 V working voltage with 6 kW heating power — confirm your supply matches before you commit.
- Water: is there a tap within hose reach, and is it potable or process water? The HW02 page specifies a tap-water inlet with a 4-point internal-tooth joint (1/2 inch), so note your fitting.
- Drainage and run-off: floor drain, gully, bunded wash bay, or nowhere at all. Where there is no drain, low-water steam becomes the practical option rather than a preference.
- Mobility: door widths, floor slope, thresholds, wet or oily flooring, and whether the machine must be driven, pushed or carried. The mobile units in the cleaning equipment range are described for indoor garages and narrow parking spaces — measure your own access and ask whether it matches.
- Environment: indoor or outdoor, ambient temperature in winter, dust or flammable atmosphere, and any site rule about hot surfaces and steam near operators.
State the mode you expect, but let the vendor argue
Steam machines are commonly offered with dry steam, wet steam and hot-water modes. Dry steam uses less water and is better where run-off is a problem; wet steam and hot water carry more heat into heavy deposits faster. You do not have to solve this in the brief — but do say that you want the modes justified against your soil and your drainage, not just listed.
Ask explicitly for the published figures: heating power, working temperature, pressure, tank capacity, dimensions, and what is included in the price. If a figure is missing from the datasheet, list it as an open question in the brief instead of assuming it. Steam temperature and pressure, battery runtime and accessory sets are not published for every model on this supplier's pages, so write them into your request as items to confirm in writing.
Cover safety, compliance and the paperwork you will be asked for
Ask which protections are fitted and how they behave in your conditions. The HW02 page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection among its features. Rather than repeating a count, ask the vendor to confirm the protection set for the exact configuration quoted.
If your site has food, medical or hygiene requirements, say so in the brief. Cleaning in a food plant or a clinical area changes the material of the tank, the way the machine is stored between uses, and how the cleaning procedure is documented for audit. In clinical settings, the hand-pushed units in the range are described for cleaning and disinfecting hospital beds and medical machinery — confirm the fit against your own procedure.
Add the commercial terms you actually care about
- Lead time, and what happens if the specification changes after order.
- Warranty scope, what voids it, and who services the machine locally.
- Spare nozzles, hoses, seals and filters, with part numbers and prices.
- Operator training, in your language, and whether it is on site or remote.
- Whether the machine can be modified later, since your line layout will change.
Ask for a trial on your own soil
The cheapest way to avoid a bad purchase is to clean one real machine with the real candidate unit. Put that in the brief: request a demonstration on your equipment, or a video of your soil type cleaned with the exact model and nozzle set you would receive. Photograph the result. Compare time spent, water used and how much drying the operator still has to do.
If the vendor will not test on your soil, treat that as an answer about their confidence, and go elsewhere.
What the brief should deliver
Send the vendor a document with six blocks: the equipment list with sensitive points; the soil description; the cleaning window and crew; the utilities and access at each cleaning point; the required modes and open specification questions; and the commercial terms. A supplier that can build both automated production line solutions and standalone cleaning machines can answer a brief that detailed quickly, and the same document becomes your acceptance checklist when the equipment arrives.
Common questions about the equipment brief
Do I need to know the steam temperature I want? No. Describe the soil, how long it has been there, and your drainage limits. Let the vendor propose the temperature and pressure, then ask them to justify it and put it in the datasheet.
What if I cannot measure my access properly? Send photographs from the machine to the door, including a person in the frame for scale, plus the narrowest opening you know of. Vendors will normally flag a mismatch instead of shipping a machine that cannot reach the cleaning point.
Is one brief enough for several sites? No. Utilities and drainage differ per location, and that is what changes the model. Write one brief per cleaning point and let the vendor consolidate the quote.
