Start with the floor plan, not the model number
Write down how the machine has to move. A bay that is 2.5 m wide with a car parked in it leaves almost no room for a hand-pushed cart plus a hose drag. In that layout a driving style steam cleaner travels to the vehicle instead of being pushed around it, which changes what the operator carries and where the unit can wait between jobs.
Record four measurements in the brief: the narrowest aisle, the door width the machine must pass through, the length of the working run from the water inlet to the farthest bay, and whether the floor is a ramp or has a threshold. If the unit must be driven outdoors, say so — the PowerDe mobile active-water machines are described for indoor garages and narrow outdoor parking spaces, and their battery version versus no-battery version is a real choice you should state up front.
Describe the soil, not just the surface
"We clean cars" tells a supplier nothing. Detailing workspaces deal with different soils, and each one points to a different mode. Road film and dust on painted panels respond to wet steam. Compact grime in wheel arches, door jambs and underbody trim needs heat plus pressure. Interior work — seats, trim, vents — is usually a low-moisture job, which is where dry steam is the better setting. A good brief lists the top three soils you deal with daily and where they sit.
If your shop also handles engine bays, say so explicitly and ask how the supplier handles that task. Engine compartment steam cleaning is a listed application for the fixed PowerDe HW02 unit, together with vehicle exterior work at service stations and parking areas and interior vacuuming and disinfection. Whether your engine work is on a lift, in a pit, or on the ground affects the hose and wand setup you should request.
State your utilities in writing
This is where most briefs quietly fail. In the brief, list:
- Available supply voltage at each bay — 220 V, 380 V, or battery-only operation with a charging point
- Water source: municipal tap line, storage tank, or none within reach
- Drainage and whether run-off is allowed on the floor or must be captured
- Heating or ventilation limits in an enclosed garage, since steam adds heat and moisture to a closed room
The fixed HW02 is documented on 220 V with a tap-water inlet using a 4-point internal-tooth joint. If your inlet is a different fitting, put that in the brief rather than discovering it at delivery. For a battery-driven mobile unit, ask for the runtime figure and the charger specification in writing; where the product page does not publish battery capacity or run time, request it from the manufacturer and treat the answer as part of the quotation.
Define the mode you actually need
A commercial steam cleaning machine for a detailing shop is usually specified by its modes rather than by its power rating. Dry steam, wet steam and hot water do different jobs. Dry steam is the low-moisture option for interiors, electronics-adjacent areas and anything that must stay workable immediately. Wet steam carries more heat into a surface and suits encrusted trim. Hot water flushes loosened soil away, which matters when you are working on floors, wheel arches and mats.
Ask for the mode switching steps in the operator's own words: how long from standby to dry steam, how long before hot water, and how many people on your team need to learn it. A machine your staff can switch modes on without a manual gets used; one they cannot, does not.
Set the service terms before the price
Put these line items in the brief so the quotation answers them:
- Warranty period, and what is excluded — heating element, pump, seals and battery are wear items on different schedules
- Spare-parts availability and lead time for the nozzle, hose and seals you will replace most often
- Training: on-site or remote, and who pays for it
- Language of the manual and of the control labels, especially if your operators are not English readers
- A named contact for fault reporting, not a shared inbox
The protection features a machine carries — leakage, short-circuit, high-temperature, high-voltage and water-shortage protection are the items listed for the HW02 — should be listed in the brief as items you want confirmed on the delivered unit, along with the documentation that proves it.
What the supplier should send back
A correct response to a correct brief is not a price. It is a machine recommendation with reasons, the utility requirements your site must meet, an accessory list matched to your three soil types, and the service terms. If a supplier quotes a model before asking about bay width, voltage and soil, treat the quotation as incomplete and send the brief again with the missing facts.
Write the brief once, reuse it for every supplier, and the comparison stops being a guess. Send PowerDe your workspace layout and utility details and we will map them to a specific machine class, mode set and accessory list before you commit to a number.
