A site-readiness checklist is the document that decides whether commercial steam cleaning equipment works on the day it arrives, or spends its first week being moved from one corner of the building to another. It is written before the quotation, not after it, and its job is simple: prove the cleaning targets, the utilities, the route to them and the people to run the machine all exist at the same place at the same time. The sections below are the ones worth filling in, in the order they normally cause problems.
1. The cleaning targets, described as surfaces and deposits
Do not start the checklist with a room name. List each surface that will be cleaned, what collects on it, and how often it has to be done. A vehicle exterior at a fuel station, an engine compartment, a machine enclosure, a floor joint and a bed frame all fail and succeed for different reasons, and heat is only justified where the deposit needs it — baked-on oil, grease and organic film come off with heat and vapour; loose dust and chips do not, and adding heat to those just wastes time and creates run-off.
For every line on that list write two things: what clean looks like when the job is finished, and how long the surface may be out of service. Those two fields decide the machine you need far more reliably than any catalogue heading. Where a surface has never been cleaned this way, mark it as unproven rather than assumed, and plan to confirm it with a test on your own surfaces.
2. What must not be cleaned, and who signs that boundary
A ready site states its exclusions as clearly as its targets. Bearings and seals, guide rails, gearboxes and relubrication points, electrical enclosures, junction boxes, control cabinets, sensors, cable runs, displays, and any open pipe or intake belong on the exclusion list, together with the note that no amount of steam makes them safe to spray. Write the boundary in words an operator can act on — nozzle direction, minimum distance from gaps and connector housings, masking of displays — instead of leaving the judgement to whoever is holding the wand at 6 a.m.
Have the equipment owner or maintenance lead confirm the exclusion list in writing. That single signature prevents the commonest dispute after delivery, which is not that the machine is weak but that someone cleaned something that should never have been sprayed.
3. Power, water and drainage at the point of use
The checklist should record, per cleaning point, what is actually there: the supply voltage and the circuit capacity available at that socket or isolator, whether a water inlet is within reach of the machine and what fitting it uses, and where the run-off is allowed to go. Fixed units of the type in the Cleaning Equipment Series are designed around mains supply and a tap water inlet, so a circuit that is already carrying other heavy load, a missing drain, or a tap on the far side of the building changes the equipment choice.
Run-off deserves its own line, because it is the item most checklists skip. Greasy water from an engine bay, oily water from a workshop floor, and food soil from a kitchen area all need different routes, and a site that has none of them will discover the cost in earthworks, an oil separator, bunded flooring or recovery vacuuming. Measure the walking distance from the machine's position to power, water and drainage, and write the number down — distance is labour, and labour is the running cost of the whole method.
4. The route the machine travels, measured not estimated
Fixed machines still have to get in, and mobile ones live or die by their route. Take a tape measure to the doors, thresholds, gates, lifts, aisle restrictions and floor slopes between the delivery point and each cleaning position, and compare them against the machine's footprint. The published dimensions for the PowerDe HW02 fixed unit are 1,200 × 800 × 1,200 mm including handles, and the hand-pushed HMW3 is listed at 1,150 × 520 × 1,030 mm — numbers worth checking against a 900 mm door before an order is placed, not after.
Also record floor type and slip behaviour when wet, and whether the route crosses cable trays, pallet traffic or food handling areas. If a machine has to be lifted, that is a project cost line, and a cheap fixed unit is no longer cheap.
5. Fixed, mobile or battery: choose from the site, not the brochure
The three classes available solve different site problems. A fixed machine makes sense where there is a stable position, mains supply and water and drainage nearby, and where cleaning happens at the same place every day. A mobile steam cleaning machine suits sites where the cleaning points are spread out, where there is no fixed water point, or where one crew serves several areas; battery-powered hand-pushed units suit rooms with no supply at all but narrow access. A single site can need both, and the checklist should say which areas are covered by which class so the quotation is not a guess.
Be honest in the checklist about what the site does not yet know. The product pages in this range publish working voltage, heating power, tank capacity and some protection features, but not every page publishes steam temperature, pressure, battery capacity or runtime. Those gaps are questions for the supplier before purchase, not assumptions to carry into a plan.
6. Duty cycle and the capacity that feeds it
Write down how many cleaning tasks per day or per shift, how long each one takes, and how they are fitted around production or trading hours. Then match that against tank capacity, warm-up time and how the machine is refilled. An 80-litre stainless tank on the HW02 and a 50-litre tank on the HMW3 translate directly into how many times an operator stops to refill, and that number is what a supervisor feels over a shift. If the schedule has no window for warm-up, refill and drying, the schedule is wrong, not the machine.
7. Safety provisions and operator competence
List the protective functions the machine provides and what an operator should do when one trips — the HW02 page names leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection, and a machine that keeps tripping one of those needs to be reported, not reset repeatedly during a shift. Then list the personal protective equipment, the training and sign-off required before anyone uses the machine, and the rule for cooling surfaces before steam goes near them, since vapour off a hot surface scalds instantly and hides what the operator is looking at.
Include housekeeping: signage while a wand is live, who keeps other people out of the work area, and how the floor is left dry enough to walk on.
8. Acceptance test and what counts as proof
Before ordering, define a bounded test: the three worst surfaces on site, cleaned by the supplier's machine or by you, timed start to finish. Record the seconds of dwell on the deposit, the number of passes, whether the mode was dry or wet steam, how run-off was collected, and the elapsed time to dry and return to service. Those five measurements turn a demonstration into evidence, and they also give you the per-task durations to put in the schedule.
Compare against your own current baseline — labour hours, water and detergent, downtime, failed inspections, disposal — in the same units for both methods. Numbers that come from a supplier's presentation are not comparable to numbers from your own log.
9. Service, spares, water quality and records
A checklist that stops at delivery is incomplete. Record the service interval, the wear items to hold on site (seals, nozzles, hoses, brushes), the warranty terms and who answers the call when heating stops. Add the water you actually have: hard supply scales a heater and output falls long before the machine fails, so state the descaling routine and who owns it. Finally decide what record each clean produces — machine, mode, area, operator, time — because in food, medical and fleet settings the record is what auditors ask for, and it is also how you spot a task that keeps slipping.
10. Scope, responsibilities and the questions to send with the checklist
Close the document with an explicit split of who supplies what: machine and accessories, electrical work to the point of use, water and drainage works, flooring or containment works, training, and spares. Ambiguity here becomes a variation order later. Then send the checklist itself to the supplier with photographs of the worst deposits and the measured door widths, and ask for a configuration matched to those facts. Where the site is unusual — several scattered cleaning points, no fixed water, a narrow access route — customized steam cleaning equipment specified against your layout and duty cycle is usually a better starting point than a catalogue selection, and the questions should be sent before the quotation, not after delivery.
A note on scope: the PowerDe HW02 product page documents vehicle exterior cleaning at fuelling and parking sites, interior vacuuming and disinfection, and engine-compartment cleaning. Applying a fixed steam machine to kitchens, machine exteriors or medical furniture is an adaptation each buyer should confirm on their own surfaces during a trial rather than read as a datasheet claim.
