1. Start with what the trial proved about grease removal
The first question is not how the machine performed overall, but which soil layer it actually removed. Kitchen grease comes in bands: fresh splatter on a hob, polymerised film on backsplashes and oven casings, and thick deposits inside hoods, filters and ducts. A machine that clears the first band may do little on the third.
Before the next cleaning shift, walk the trial area with the operator who held the wand and mark three things: surfaces where grease lifted in one pass, surfaces that needed repeated passes, and surfaces where residue remained. That map tells you which part of the kitchen the machine suits and which part still needs soaking, disassembly or a contracted duct clean. High-temperature central commercial kitchen degreasing machine trials tend to look strongest on open surfaces that can be reached directly, and weakest where deposits have hardened over months.
2. Review the working conditions, not just the result
Trial results depend heavily on how the machine was run, and real shifts are less forgiving than a demo. Record the practical constraints while they are fresh:
- Was the unit plugged into a socket that the kitchen normally has free, at the voltage available in that area?
- How long did heating take before steam reached the surface, and did output drop during a long session?
- How often did the tank need refilling, and where was the water inlet relative to the work area?
- Did hoses, cables or the machine footprint block walkways, doors or service access?
- Could the work be done outside service hours without disturbing neighbouring areas?
If the trial was run by the supplier's engineer, repeat it with your own staff. Technique matters: wand distance, pass speed and when to switch from a drier steam to a wetter one are all learnable, and an untrained operator will produce a weaker result on a fixed machine than on a demo.
3. Check the machine against your fixed equipment
Most kitchens clean on a fixed schedule, in a fixed place, after service. A stationary unit that stays near the hot line is usually more practical than a mobile one that has to be transported, charged and stored. The Fixed Steam Cleaning Machine PowerDe HW02 page, for example, lists a 220 V unit with 6 kW heating power, 160° steam temperature, 0.8 MPa vapour pressure, an 80 L SUS304 tank and a footprint of 1,200 × 800 × 1,200 mm including handles, plus a switch between dry and wet steam.
Measure your own space before comparing those numbers: the distance from the nearest power point, the width of the aisle the machine must pass through, and where waste water will run off. Also check what the supplier does not publish. Runtime per charge, hose length, accessory list and water consumption are often absent from product pages, and those omissions decide whether the machine fits your shift pattern. Ask for them in writing rather than assuming.
The same caution applies to claims that sit outside the product page. Vendor material may name a kitchen application while the detail page describes other uses. Where wording differs between a title and a parameter table, do not commit to a figure in your internal paperwork until the supplier confirms it. A central kitchen degreasing specification should be verified against your own equipment list, not accepted from marketing copy.
4. Test the wet side of the job
Steam softens grease; it does not make it disappear. Emulsified grease and rinse water have to be captured and disposed of, and kitchens that skip this step trade one problem for a slip hazard. Review what the trial left behind: standing water near the hot line, runoff paths toward drains, and how long the floor stayed wet. For a commercial kitchen floor steam cleaning session, the real cost often sits in the drying and clearing time afterwards, not in the steaming itself.
Decide, before purchase, who vacuums or mops up, where the runoff goes, and whether your drainage accepts grease-laden water at all. If the trial did not answer these, run a second session and weigh the residue bucket. That single number tells you how much waste the process generates per shift.
5. Look at safety and hygiene documentation
High-temperature, high-pressure steam is not a household appliance. Ask what protective functions the unit provides and how they behave in a kitchen environment: leakage, short-circuit, high-temperature and water-shortage protections are commonly listed on PowerDe cleaning machines, but the exact set varies by model, so confirm the list for the specific unit rather than quoting a count.
Then cover the human side. Are operators given training on wand handling, personal protective equipment and safe distances from hot surfaces? Is there a written procedure for use near electrical equipment and gas appliances? In a food operation, cleaning chemicals displaced by steam also need documenting: if the process reduces detergent use, update the cleaning schedule and the food safety file so the change is traceable during audit.
6. Put the trial into your cost and audit records
Comparison tables built from brochures rarely survive contact with a real site. Use the trial data instead. For each shift the machine ran, note labour hours spent, water and energy consumed, consumables used and the time the kitchen was out of action. Compare that against the current process, including whatever a contractor charges for hood and duct work.
Also review what your inspectors see. Grease build-up around hoods and ducts is a fire and hygiene exposure, and a documented internal cleaning record for restaurant kitchen grease cleaning is worth more at inspection than a machine nobody operates. If the trial shortened the interval between deep cleans, that saving belongs in the business case.
7. Decide what to ask the supplier next
A completed trial should leave you with a short, specific question list rather than a general impression. Ask for the missing figures; ask which accessories are included and which are extra; ask what warranty covers for a unit working daily in a humid, greasy room; and ask for a service arrangement, since a machine that is down for a fortnight leaves the kitchen with its old process. If you serve several sites, ask whether one model fits all of them or whether sites need different configurations.
If the trial was inconclusive, run it again on the worst surfaces, at the time of day the kitchen actually closes, with your own staff. A second session that mirrors your operation is a better buying basis than a successful demo on a clean surface.
The decision to take forward
A steam-cleaning trial answers one narrow question: can this machine remove the grease in this kitchen. The review afterwards answers the question that matters commercially — can it do so every day, with your staff, in your space, at a cost you can justify. Record the surface map, the working conditions, the wet-waste handling and the missing specifications, and the purchase decision usually makes itself.
