When a plant adds steam cleaning to the routine for industrial presses, the quote that lands on a manager's desk is rarely just a machine price. Purchasing wants the cleaning labour line to shrink, maintenance wants fewer unplanned stops, and the safety officer wants to know who will be standing next to a hot machine and for how long. Comparing labour needs across two options therefore means putting both options through the same sequence of work steps, rather than arguing about specifications. The industrial steam cleaning equipment range at Shenzhen PowerDe Automation Precision Equipment covers fixed and driving-style machines, and the way the tasks are staffed around them is what usually drives the labour difference.
Write down the task list before comparing any numbers
Start with an hour-by-hour description of what the crew does today on one press: isolating and locking out the machine, covering or disconnecting nearby electrical parts, scraping accumulated grease and metal fines, applying detergent and letting it react, rinsing, wiping, drying the floor, and cleaning up the run-off. Add the walking and set-up time between presses, which is easy to forget and often decides the result in a large shop. Write the list twice: once for the current manual routine, once for the steam routine, and keep the two side by side. Any labour estimate that skips this step compares two invisible processes instead of two visible ones.
Compare the labour that each step consumes
For both columns, record three numbers per step: the number of people needed, the minutes of attendance, and the number of separate trips back to a sink, hose reel, or supply point. High-temperature, high-pressure steam is aimed at shortening the chemical-reaction and scrubbing portions of that list, because the work of lifting heavy grease shifts from mechanical effort and dwell time to directing the lance at the surface. Heavy-duty steam cleaning machine models switch between dry and wet steam, so the crew spends less time on drying and on managing standing water — a step that disappears from the sheet rather than becoming faster. Reduced water use and lower reliance on chemical detergents also remove the supply, mixing, and disposal steps that add staff time without touching the machine.
Do not count a machine in place of the person beside it
A fair comparison keeps the operator in the model. Steam work still requires someone to aim the lance, and on a fixed installation someone may also be needed to move hoses, monitor the work area, and handle the machine. What changes is who does the heavy part and for how long. The Fixed Steam Cleaning Machine PowerDe HW02 is a 220 V unit with 6 kW heating power, 160° steam temperature, 0.8 Mpa vapor pressure, an 80 L SUS304 tank, dimensions of 1,200 × 800 × 1,200 mm including handles, a tap-water inlet with a 4-point internal-tooth joint, 1/2 inch, and switchable dry and wet steam. The fixed layout matters for labour in a practical way: the machine is installed once at the work area, so the crew is not pushing, lifting, or re-positioning a unit between presses, and the water inlet is a plumbing connection instead of repeated tank refilling. Confirm with PowerDe which configurations and accessories are offered for this model before you put the accessory steps into your own time sheet.
Convert the difference into crew-hours, not into percentages
Once both columns exist, the comparison becomes arithmetic. Take total crew-minutes for one press cleaning in each column, multiply by how many presses are cleaned per week and by how many shifts are affected, then multiply by the loaded labour rate that applies to the people doing this work — including overtime if cleaning happens outside production hours. Add the indirect labour that follows from the sequence: waiting for surfaces to dry before production restarts, moving products or tooling out of the way, and re-inspecting residues left by manual scrubbing. Two sites with identical cleaning durations can produce different labour answers simply because one of them cannot restart production until the floor is dry.
Run one measured trial on one press before committing
Ask suppliers to support a trial on a machine you choose, on your shift pattern, with your own staff recording the numbers above. That trial answers questions no data sheet can: whether the reach of the lance covers the frame and guarding of your press design, whether the shop has the power supply and water connection the installation needs, how the machine's protection features behave in a wet environment, and how quickly your crew becomes efficient with it. Describe the grime you actually have — pressing oil, drawing compound, graphite, mixed dust — and the surfaces involved, so the configuration proposed matches the shop floor. PowerDe's customized steam cleaning equipment services cover the survey and configuration stage for this kind of application.
If your team also cleans machine exteriors elsewhere in the shop, compare the driving-style options on the same sheet rather than mixing the two routines in one estimate. Mobile units change the walking and transport figures, which is precisely where a fixed installation changes them in the opposite direction. Comparing the two installation types on the task list — not on the machine list — is what lets you defend the labour figure afterwards.
