A purchase enquiry for a industrial steam cleaner can arrive with a single line: “please quote 20 units.” The supplier who replies with a price in ten minutes usually loses the deal anyway, because the number they gave is a guess. Quoting washing equipment is not arithmetic — it is engineering. The information you collect before the calculation decides whether the machine is the right one, whether it will pass the site’s electrical and safety checks, and whether the buyer has to pay twice.
1. What is actually being washed, and what soil is on it
Start with the surface and the soil, not the machine. Vehicle bodies, engine compartments, hospital beds, machine tools and food-area floors all need steam, but they need different steam. Loose dust and light road grime come off with comparatively little heat. Polymerised oil, cutting fluid residue and kitchen grease need sustained high temperature to be lifted at all, which puts the emphasis on heating capacity rather than on tank size. If the buyer cannot describe the soil, ask what a normal dirty item looks like and what has to be true after cleaning — “no visible film”, “no residual odour”, “safe to touch” are the answers that matter.
Then ask whether the surface is temperature- or pressure-sensitive: painted panels, seals, bearings, electronics, wooden floors and coated metals each react differently to a hot jet. A quotation that ignores this produces a machine that cleans well and damages the thing being cleaned.
2. Whether the work is fixed-station or moving
The same daily volume produces completely different equipment depending on where the operator stands. A wash bay, a service station forecourt or a central kitchen usually points to a fixed machine with a large tank and mains power. Our fixed unit, listed as Fixed Steam Cleaning Machine PowerDe HW02, is built for exactly that pattern: vehicle exterior cleaning at petrol stations and car parks, interior vacuuming and disinfection, and engine-compartment work, with a stainless steel tank and separate dry-steam and wet-steam settings plus a vacuum function.
Where the vehicle moves and the machine must follow — indoor garages, tight outdoor parking areas, fleets parked along a yard — the answer is a mobile unit instead. The driving style steam cleaner in our range travels under its own power, can be stopped and driven at any point in a narrow space, and offers dry steam, wet steam and hot water in one machine. Tell the supplier the walking or driving distance between items to be cleaned; that single fact often decides between the two families.
3. Power, water and other utilities on site
This is where unverified quotations fall apart. Send the supplier a photograph of the distribution board and state, in writing: supply voltage and phase, the rating of the nearest protected outlet, cable run length, and whether the circuit is shared with other equipment. Mains-powered machines in our catalogue are specified at 220 V, while some mobile models also run from a replaceable battery pack; a site with 110 V single-phase supply, or a battery-only requirement, changes the recommendation entirely. Never let the supplier assume a voltage.
Water needs the same treatment. Steam machines are efficient with water, but they still need a feed: is there a tap within hose reach, what is the fitting thread, and is the supply clean enough to feed a heater? Our product pages list the inlet as tap water with a specific internal-tooth joint; if the site supply is hard, untreated or recycled, say so in the enquiry so that water treatment can be quoted alongside the machine rather than discovered after delivery.
4. Throughput, shift pattern and duty cycle
Give the numbers as a working day, not a monthly total: items cleaned per hour, hours per shift, shifts per day, and how long the machine rests between peaks. A machine sized for four cars an hour will be pushed far past its intent on a forecourt doing forty. Duty cycle also drives the tank and heater question — continuous operation favours a larger tank and higher heating output, while intermittent use may make a compact unit the better purchase.
Ask the same of the operator. How many staff, and what is their training level? A unit with battery handling, charging routines and several cleaning modes needs a different instruction plan from a plug-in machine with two settings.
5. Access, dimensions and floor conditions
Send measurements of the doorway, lift, ramp and aisle the machine must pass through, and of the floor it will work on. Fixed machines are substantial — our HW02 is recorded at 1,200 × 800 × 1,200 mm including handles — while mobile units are narrower by design so they can work between parked cars. A machine that cannot leave the loading dock is a return, not a purchase. Note surface gradients and drainage as well; steam cleaning produces run-off, and sites without drainage restrict what can be used safely.
6. Hygiene, safety and compliance expectations
State the rules you have to satisfy, even if they feel obvious: food-area or hospital cleaning, fire-officer requirements for extraction areas, workplace safety rules for high-temperature jets, or a client contract that specifies disinfection. Hygiene-driven sites often need a machine that runs dry steam for long periods and a supplier who can document what the machine does. Ask what protection features are built in; the safety set our pages describe includes leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, and the item list should be confirmed for the exact model quoted rather than assumed across a range.
7. Variants, accessories and consumables
Ask the supplier to quote the variants explicitly. Battery-included and battery-excluded versions are sold separately in our range, and the difference changes both the price and the charging arrangements on site. Then list the nozzles, lances, hoses, brushes and vacuum tools actually needed for the surfaces from point 1, plus filters, seals and heater elements as spare parts. A quotation that names only the base machine hides most of the lifetime cost.
8. Service, spare parts and lead time
Put the support questions in the enquiry itself: which parts are stocked and where, how a failed heater or pump is replaced, what remote support looks like, what the warranty covers and excludes, and how the machine is delivered, commissioned and demonstrated. If the buyer’s language, local plug standard or inspection regime differs from the factory’s, say so now. A quotation is only comparable when every supplier answers the same support questions.
9. What to expect from the quotation itself
A serious quotation names the model, states the electrical and water requirements, lists the accessories included, gives delivery terms and lead time, and flags anything the supplier assumed because the enquiry was silent. Read for those assumptions first, price last. If a supplier quotes without asking what is being cleaned, what power and water the site has, and how many items per shift, treat the figure as provisional at best.
A short pre-quotation checklist
- Surfaces and soil type, plus the required result after cleaning
- Fixed station or mobile working, with travel distance between items
- Supply voltage, phase, circuit rating, cable run, battery needs
- Water supply, fitting type and water quality
- Items per hour, shifts per day, rest periods, operator count and training
- Doorway, lift and aisle dimensions; floor gradient and drainage
- Hygiene, safety and inspection requirements that apply
- Battery variants, accessories, consumables and spare parts
- Warranty, spare-part stock, support model, lead time and commissioning
Send that list with the enquiry and comparable quotations come back. Shenzhen PowerDe Automation Precision Equipment builds and customises cleaning equipment for vehicle, commercial, industrial and medical use, so an enquiry carrying these details can be routed to the right model — or to a modified one — in a single pass. Contact our team with the checklist above and we will specify the machine, the accessories and the utilities it needs before we quote.
