A car-wash operator who asks for a quote on a cleaning machine usually sends a one-line request: “steam cleaner, please quote.” The supplier replies with a catalogue. Three weeks later nobody has bought anything, because the catalogue answer was not the question. A short, complete equipment brief is what turns a supplier conversation into a working installation.
If you are buying for a wash bay, a detailing garage, or a parking facility with its own cleaning point, here is the information to put in the brief before you contact a supplier such as Shenzhen PowerDe Automation Precision Equipment.
1. The site itself
The machine has to fit the room. Describe it concretely:
- Indoor or outdoor, and whether the bay has a roof or is open to rain and freezing temperatures.
- Bay dimensions, ceiling height in indoor garages, and the width of the entry — narrow garages and tight outdoor parking spaces rule out larger fixed cabinets and favour compact or drive-up units.
- Floor surface, drainage points, and whether run-off has to be contained.
- Distance from the machine to the farthest point you clean, which sets the hose and wand reach you need to ask about.
2. Available utilities
Most cleaning-equipment problems after delivery are utility problems, not machine problems. State clearly:
- Supply voltage on site — for example single-phase 220 V — and the socket type and breaker rating.
- Whether a water connection is available. Several PowerDe steam units are listed with a tap-water inlet, so a nearby tap matters; where there is no tap, ask how the tank is refilled and what capacity is practical.
- Whether battery-operated mobile units make sense because cabling across a wet area is unsafe or impractical.
3. What you actually clean, in order of frequency
List the tasks and rank them. A typical car-wash brief covers vehicle exteriors, interiors, engine compartments, and the floor and wall surfaces of the work area. Some sites also clean bins, mats, hoses, and hard-standing. This ranking tells the supplier which functions are core and which are optional, and it decides between a drive-up mobile machine and a fixed unit.
In PowerDe’s cleaning range this split is visible on the product pages. The driving style steam cleaner line is presented as a mobile active-water machine with dry-steam, wet-steam and hot-water modes for indoor garages and narrow outdoor parking spaces. The fixed PowerDe HW02 steam cleaner is described for vehicle exterior cleaning at gas stations and parking lots, interior work and engine-compartment cleaning. If your site runs one bay and a lot, a mobile unit and a fixed unit are not interchangeable — say which one you are evaluating.
4. Duty cycle and staffing
Give real numbers you already have, not targets. Per day: how many vehicles, how many engine-bay jobs, how many interior jobs. Per shift: how many operators, and how long the site is open. Ask the supplier to state, for the model they propose, the tank capacity, heating power and how long the machine runs before it needs refilling or reheating. Where a figure is not published, ask for it in writing rather than assuming it.
5. Steam mode requirements
Say what you need the machine to do, not what you think it is called. Useful phrasing in a brief:
- Drying with little moisture, for electrical areas, engine bays and enclosed compartments.
- Wetter steam for stubborn grime on floors, walls and mats.
- Hot-water mode where soil volume is too heavy for steam alone.
- Vacuum function for interiors, if the machine is expected to handle it.
PowerDe’s cleaning machines are offered with dry-steam and wet-steam modes, and the driving-style models also list hot water. Confirm which modes a specific variant includes, since the same model name appears in battery and no-battery versions.
6. Water and chemical policy
Many buyers choose steam or hot-water equipment because it reduces the volume of water used and the amount of detergent carried into the drainage system. Put your own constraint in the brief: whether you must limit water use, whether detergents are restricted, and whether the site has any discharge requirement. Ask the supplier to describe how their machine’s water consumption compares with the pressure-washer setup you use today.
7. Safety and protection features
Ask for the protection features as a list on the machine you are being quoted, and keep the wording from the datasheet. PowerDe’s cleaning pages describe protections such as leakage, short-circuit, high-temperature and water-shortage protection on several models, with the exact set varying by machine. Match the list to the model, and ask what interlocks exist if the machine is used by staff with no cleaning-equipment training.
8. Moving the machine on site
A machine that cannot reach the bay is useless. Specify whether it will stay in one place, be pushed across a wet floor, or be driven between positions. This is where the format question belongs: PowerDe cleaning equipment is listed as driving-style, hand-pushed and fixed configurations, and those three formats behave very differently in a narrow garage.
9. Service, spare parts and documentation
Put your service expectations in the brief from the start:
- Language and format of the manual, and whether an English-language version exists.
- Consumables and wear items, with part names, so you can buy them locally.
- Warranty terms, response time, and how a failed part is replaced from overseas.
- Whether the supplier will support a trial or a demonstration before shipment.
10. Your own scope for customisation
If your site has a non-standard requirement — a machine built into a cabinet, a specific colour, a branded panel, or an arrangement that suits your bay — say so in the first message. PowerDe lists customised configurations, product development and hardware testing among its engineering services, and stating your constraint early is what lets a supplier separate “we can do this” from “we cannot.”
A short template you can paste into an enquiry
Site: indoor garage / outdoor lot, open how many days per week.
Bay size and ceiling height; distance to farthest cleaning point.
Utilities: voltage, socket, tap-water availability, drainage.
Work per day: vehicles, interior jobs, engine-bay jobs, floor cleaning.
Operators and shift length.
Modes needed: dry steam / wet steam / hot water / vacuum.
Water and detergent constraints, discharge rules.
Mobility: fixed, hand-pushed or driven.
Required documentation, spares and warranty expectations.
Anything custom.
Before you send it
Two checks save a round trip. First, confirm that every number in your brief is measured, not remembered — bay widths and socket ratings are where quotes go wrong. Second, when you compare replies, ask each supplier for the same published parameters for the proposed model, and treat any figure that only appears in an email as unconfirmed until it is on the spec sheet. That single habit makes quotations comparable instead of merely cheap.
