A buyer who sends a photo of a dirty range hood and asks “which machine do I need?” is asking the wrong question, and any supplier who answers it immediately should not be trusted. Recommending steam cleaning equipment for kitchens and other food-service areas starts with a supplier-side questionnaire. The answers decide the machine class, the utility hookup, the accessories, and whether the cleaning result will actually hold up day after day.
1. What surfaces and geometries are in scope?
“Kitchen piping” is not one surface. Exhaust ducts, hoods, extract fans, grease filters, wall cladding, stovetops, floors and equipment housings all behave differently. Rounded ductwork and welded seams trap baked-on grease in ways a flat stainless worktop never does, so the supplier needs drawings, photographs of the worst corner, and a rough count of the runs to be cleaned. Geometry drives the nozzle set, the extension lance length, and whether an operator can physically reach the surface.
2. What is the soil, and how thick is it?
Light food residue and hardened cooking grease are different jobs. A supplier should ask when the surfaces were last cleaned, whether the grease is soft or polymerised, and whether the site cooks by frying, grilling, or steaming. Heavy, aged grease needs high steam temperature and sustained pressure at the nozzle, not just a bigger tank. A supplier who cannot describe the soil in the buyer’s own words has not answered the first qualification question, and the wrong machine will show up as a poor cleaning result rather than as an obvious mismatch.
3. What utilities exist at the cleaning point?
This is where most recommendations go wrong, and it is a question the buyer usually has not considered. Ask for the available supply: is there a fixed steam cleaning machine location with a stable 220 V supply, or must the equipment move between floors, yards and bays? Mains-connected units such as the PowerDe HW02 run on 220 V with a 6 kW heater, an 80 L tank and tap-water inlet, and are suited to a fixed position with dependable power and water. Battery-powered units trade continuous output for freedom of movement. Choosing between them is a utilities question, not a preference question.
4. How far does the operator travel between the machine and the surface?
Distance changes the recommendation. Long runs across a site favour a mobile unit, and where the route includes narrow aisles or a step, a hand-pushed machine is usually the practical choice. For a machine used on long, repetitive passes over ductwork or a row of hoods, the supplier should ask about hose length, wand reach and how often the operator would otherwise have to stop and reposition the cart. Every avoidable reposition costs time on every single clean.
5. How often will it be used, and by whom?
A cleaning contractor running several sites a week has different requirements from an in-house maintenance team cleaning a hood once a month. Ask who operates the machine: an experienced cleaning technician, or kitchen staff with no cleaning training. For mixed or rotating operators, protective functions and straightforward mode switching matter more than peak output. The PowerDe range offers dry steam and wet steam modes on both fixed and mobile machines, and a supplier should ask which mode the site expects to use most rather than leaving it to guesswork.
6. What are the water and drainage conditions?
Ask how the machine is refilled and where the run-off goes. A kitchen with a floor drain behaves differently from one where water has to be mopped up. Steam-based cleaning uses far less water than a pressure washer, which is often the reason a buyer is considering it, but the supplier still needs to know about the drain, the tank capacity and whether clean water is available at the point of use. An 80 L tank is an advantage only if there is somewhere to fill it without dragging a hose across a food room.
7. What are the hygiene and access constraints?
Food areas and healthcare areas bring their own rules, and a competent supplier will ask about them before quoting. Working hours, whether the kitchen must stay open, whether cleaning happens while equipment is warm or cold, and what disinfection requirement the site has to meet all change the recommendation. Where the same buyer also cleans medical equipment or ward furniture, that is a separate requirement and should be treated as one, not folded into the kitchen quote. Our PowerDe cleaning equipment range covers hand-pushed and fixed machines for these environments, and each machine is documented separately for that reason.
8. What does “done” look like in the buyer’s contract?
Ask what the buyer is accountable for. A contractor answering to a hygiene inspection needs a different standard from an operator cleaning for appearance. The supplier should get the inspection or acceptance wording, then state plainly which parts of it the equipment achieves and which depend on operator technique, dwell time and detergent choice. Suppliers who promise that a machine alone will satisfy a specification are describing a hope, not a process.
9. Is the standard catalogue enough, or is this a custom build?
Some sites need a different tank, a different mounting, a modified accessory set or a machine integrated into their own workflow. If the answers to questions one to eight do not match any catalogue machine, say so. Shenzhen PowerDe Automation Precision Equipment builds customised configurations and supports equipment development and testing for buyers whose requirement falls outside the standard range. Naming that at the questionnaire stage avoids a purchase that has to be re-specified after installation.
What a good supplier sends back
A proper answer to this questionnaire is not a brochure. It is a named machine, the utility requirements for the chosen location, the accessories included, the mode settings expected for the buyer’s soil type, and a clear statement of what the operator still has to do. Buyers should judge supplier proposals on that level of specificity, because the machine that fits one kitchen is regularly the wrong machine for the next one.
Send your surface list, photographs of the heaviest soil, your available power and water supply, and your cleaning frequency to the contact details on our contact page, and you will get a configuration based on those answers rather than a catalogue dump.
