1. What exactly is the floor built from, and where does water go?
Start with your own floor, not the machine. Slip-rated tile with epoxy grouting, resin screed, or old concrete with cracks and lifted edges each behave very differently once heat and pressure are applied. Loose grout and failed seals will let water under the screed, so a floor that has not been re-pointed recently needs repair before any pressure-based cleaning programme. Then map the drainage: how the floor falls to channels, where water stands after washing, and whether the wash water can be directed to a drain that handles organic load. On the PowerDe cleaning equipment range, mobile and fixed machines differ in tank size, supply connection and how the operator moves around the space — which matters most when the floor is a maze of tank legs, pallets and hose reels.
What a good supplier answer sounds like: they ask for a floor photo, the finish type and a plan of the wash area. A weak answer: a generic recommendation with no questions about your substrate or drainage.
2. Can the machine reach the residue, or only the open floor?
Open floor is the easy part. The audit findings in beverage plants usually sit in the hard places: under and behind vessels, along wall-to-floor coves, around valve clusters, on the wheeled bases of trolleys, and in the grout lines that a mop only spreads through. Ask the supplier to describe the lance, nozzle and brush options and how the machine is moved into position, because a unit that cannot be brought to the work will not be used for it.
The mobile units in the PowerDe cleaning equipment series are built around this reach problem — the driving-style and hand-pushed models are described for indoor garages and narrow parking spaces, which is the same constraint as a tight brewhouse aisle. Fixed units, by contrast, assume the operator walks a hose to the job. Decide which pattern matches your layout before you compare specifications.
3. Which cleaning media does the process need: dry steam, wet steam, or hot water?
This is the technical question that decides the machine class, and it is worth getting a straight answer on. Dry steam carries heat with very little free water, so it suits surfaces that must stay workable and areas where standing water is the problem you are trying to remove. Wet steam adds moisture to loosen baked-on sugar and yeast film. Hot water does the bulk rinsing on open floor. Some of the driving-style models are specified with dry-steam, wet-steam and hot-water modes in one unit, which means the operator selects the medium per task instead of running two machines.
Ask for the working steam temperature and vapour pressure as published figures, and confirm them on the data sheet for the exact model. Published specifications differ between models and are not listed uniformly across the range, so treat any number quoted in a sales conversation as unverified until it appears in the specification table. For a floor programme, also ask what the machine does at the end of the shift: how residue leaves the surface, and how much water is left on it.
4. How does the machine fit a cleaning schedule that runs around production?
Brewery cleaning windows are short and often unsocial. Ask practical questions: how long the machine heats up before the first lance is usable, how the water tank is refilled or whether it connects to the mains, and how long it can run between refills on a full production-area sweep. Battery-powered mobile models move without a trailing cable, which matters near open drains and wet floors; mains-powered fixed models trade that freedom for continuous duty. Ask which PowerDe cleaning equipment model you can schedule into a CIP-and-wash window without stopping the line next door.
Then ask the staffing question the specification will not answer: how many people does the floor need, and does one trained operator finish the job alone? A machine that halves the crew on the Thursday deep clean usually pays for itself faster than one that adds margin to the cleaning chemical budget.
5. What does the site require around water, electricity and slip risk?
Production-area floors are wet, and the wash area is often electrically the most awkward room in the plant. Ask which supply the machine runs on, and check that your electrical supply and protection match. Some mobile models are listed with leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, and battery variants change what you need at the wall — but also create a charging and battery-care routine in a humid room. Confirm what your water connection needs, since inlet fittings and tank capacity are model-specific and are published per product page rather than as one shared table.
Write the answer into your own permits and risk assessment before the demonstration, not after. A machine that cannot legally be operated on a wet floor during your shift pattern is the wrong machine regardless of its cleaning results.
6. How will you prove the floor is clean — to yourself and to an auditor?
Move the conversation from "looks clean" to evidence you can hand to a customer or a hygiene audit. Ask what changes on the surface after steam cleaning: residue film, odour, and the visual condition of grout lines are the practical checks a plant team can run without laboratory support. Then agree the verification method before purchase — ATP swabs, visual inspection of a fixed set of hard points, and a sign-off sheet naming the operator and the area.
Ask the supplier which of their documented uses match your sector. The site positions high-temperature steam cleaning as a way to raise cleaning efficiency while cutting water use, labour intensity and reliance on chemical detergents, and it lists industrial maintenance, commercial kitchens, medical equipment and public facilities among application areas. That framing supports a business case; it does not replace your own validation on your own floor.
7. Who supports the machine when it is down on a brew day?
A floor machine becomes part of the production dependency chain, so the service questions are procurement questions. Ask what spare parts wear out — nozzles, seals, hoses, brushes — how they are ordered, and what the response path is if the unit fails during a filling run. For a plant where cleaning windows are fixed, ask whether the supplier offers customization and engineering support, which PowerDe lists among its services on the solutions pages, including customized configurations and technical support.
Then ask for training: who teaches the operators, in what language, and what happens when staff turn over. Cleaning results on a brewery floor depend more on the pass rate and dwell time than on the model number.
A short pre-purchase checklist
- Substrate and grout condition confirmed, with drainage and standing-water points mapped
- Hard-to-reach areas listed, and the machine's movement and lance options matched to them
- Dry steam, wet steam and hot-water modes matched to the soil types you actually have
- Published temperature, pressure and tank figures read from the model's own data sheet
- Electrical supply, water connection and wet-floor safety checked against site rules
- Verification method agreed: swab plan, hard-point inspection and operator sign-off
- Spares, response path and operator training agreed before the order
Take that list to a supplier with your floor photos and your cleaning schedule. If they can answer each item against a specific PowerDe cleaning equipment model, you have a proposal to compare. If they cannot, you have a vendor who has not looked at your production area — and a floor audit will tell you that far more expensively than a demonstration does.
