Why the model name alone is not enough
The PowerDe HMW2 steam cleaner is published as a driving-style machine for narrow indoor garages and outdoor parking spaces, with hot water, dry steam and wet steam modes, a high-pressure water gun, a 60-litre fresh water tank and overall dimensions of 1,275 × 570 × 1,185 mm. Those published figures already tell you what a supplier needs from you before a quote can be more than a price on a model number. The machine either fits your route, finishes your shift, and handles your soil, or it does not, and only your site data can answer that.
The six sections below follow the order of an actual quotation. For each one, note what you should state, and what the supplier decides with that information.
1. What you clean, and in what condition
Start with the task, not the equipment. List the vehicles or areas you intend to clean, how many per shift, and the realistic time window you have between shifts. Then describe the soil in the condition you actually find it:
- loose dry soil, dust and mud, which mostly needs flushing and collection;
- fresh films such as oil splash, road film or food grease, which respond to heat with a short dwell;
- polymerised old grease and baked-on or carbonised deposits, which need scraping and repeated short cycles before any single pass helps.
Add the surfaces involved and the surfaces that must stay dry or out of reach of heat: electrical enclosures, sealed bearings, printed labels, waxed paintwork, open wiring. Finally, name what is outside the scope, such as exhaust ducts beyond the first reachable section, drains, or interior machinery spaces. A supplier who reads the three soil states can map them to the hot water, dry steam and wet steam modes recorded on the product page and say which attachments belong in the offer. A buyer who writes only "vehicle cleaning" invites a generic quote that may include parts you will never fit and miss the nozzle you will use every day.
2. The route the machine will travel
Measure the route before you ask for a price: door widths at the narrowest point, clear heights, ramp gradients, turning space, lift dimensions, column spacing, floor levels and thresholds. The published mobile steam cleaning machine dimensions of 1,275 × 570 × 1,185 mm are the numbers to compare against that route, and the comparison belongs in your enquiry, not in a later phone call. Attach the measurements as a simple list with the tightest points marked.
Also state where steam will be used. Steam indoors needs ventilation, and an enclosed basement bay behaves differently from an open deck with wind. Freezing mornings, storage location and any charging corner change the answer as well. If the route crosses curbs, drainage channels or expansion joints, say so; the supplier may suggest a different machine type, and that is a useful answer to receive before an order rather than after delivery.
3. Water, drainage and power at the position
The HMW2 carries a 60-litre fresh water tank and has a 1/2-inch female-threaded water inlet. Tell the supplier where the nearest tap is, how the hose will be routed, and how far operators must work before a refill. This decides whether a second water point, a longer hose or a different routine belongs in the offer.
Drainage is a separate question: where the wash water goes, whether an oil interceptor exists, and what the local drainage authority requires. Those rules are set by your local authority, not by the machine specification, so treat them as your own item to confirm.
On power, the product page lists a 4.5 kW PTC heating element, and the working-voltage row reads 220 V with a mobile-battery note. Have your electrician check the circuit, the socket position, cable length and weather protection, and send the result with the enquiry. The protections named on the page, covering leakage, short circuit, high temperature, high voltage and water shortage, protect the machine; they do not replace a site check of the building circuit or of the floor it will stand on.
4. Battery, shift pattern and charging
The HMW2 is listed both with and without a battery, and the two listings carry the same specification table, with the battery supplied by the customer. State which version you want, how many shifts the machine will run per day, whether a mid-shift battery swap is acceptable, and where and how charging would take place.
The product page does not publish battery capacity, vehicles per charge, runtime per charge or charger output. Write down the shift pattern you need to cover, then ask for those figures in writing and check them against your own routine before ordering. A supplier who knows your shift pattern can tell you whether one battery, a spare battery or a tethered arrangement fits, and can flag the gap early if it does not.
5. Operators, training and working rules
Name the people who will operate the machine, who supervises them, and how many shifts they work. State whether quiet hours apply, whether cleaning happens at night while vehicles are parked, and what personal protective equipment your site already requires. Ask what training is supplied, in which language, and whether a refresher is available when staff change.
If your client, your insurer or your own audit requires a method statement, a risk assessment or a signed record per vehicle, say so in the enquiry. Those requirements change the attachments, the protective items and the documentation in the offer, and they are far cheaper to include at quotation stage than to retrofit later.
6. The pilot and the acceptance wording
Close the enquiry by naming the pilot. Choose one representative vehicle or one representative bay, agree the acceptance wording in writing before the trial, and set the conditions: one day, your own vehicles, timed cycles, and photographs taken from fixed reference points before and after. Agree who provides what during the trial and who covers transport.
Acceptance wording should be checkable. "The driver can see the result from standing height" or "no residue on a white cloth across the agreed panel" tells both sides the same thing; "clean" does not. If your site uses customized steam cleaning equipment requirements, such as a different inlet fitting or a colour-matched panel, raise them at this stage so the pilot tests the machine you would actually receive.
A one-page sheet to send with the enquiry
One page is enough, and a supplier is more likely to use it if it is short. Fill these fields and attach your route measurements:
| Contact and site | Company, contact person, site address, opening hours, quiet hours. |
| Cleaning targets | Vehicle types or areas, quantity per shift, available minutes per unit, shift pattern. |
| Soil description | Which of the three states appears where, with photographs of the worst case. |
| Surfaces to avoid | Electrical parts, labels, waxed or damaged coatings, sealed bearings, open wiring. |
| Measured route | Door widths, clear heights, ramps, turning space, lift size, thresholds, storage and charging corner. |
| Water, drainage, power | Tap position and distance, drainage route and interceptor, circuit and socket position as checked by your electrician. |
| Battery preference | With or without battery, shifts per day, swap policy, charging location. |
| Operators and records | Number of operators, supervision, PPE rules, documents your audits require. |
| Pilot | Named vehicle or bay, written acceptance wording, trial date, who provides what. |
What to ask the supplier back
Once the information is on their side of the table, ask for the items the product page leaves open, in writing: hot water and steam temperature and pressure; battery capacity, runtime or vehicles per charge, and charger output; the accessories included, with part numbers for wear items; warranty scope, spare-part availability and service response; and training and documentation in the language your team reads. If a figure you need is not on the page and not in the reply, treat it as unresolved rather than assumed.
A quote built on a model number describes the machine. A quote built on your task, your route, your utilities and your acceptance wording describes your job. The second one is the one worth comparing.
