Start with the shift plan, not the machine
When a commissary kitchen buys cleaning equipment, the conversation usually opens with a specification sheet: heating power, tank capacity, steam temperature. That is the wrong order. What a facilities manager, a food-service operations lead, or a plant engineer actually needs to compare is how many people, on how many shifts, it takes to keep every piece of equipment in a compliant, degreased state. The machine is only the variable that changes the answer.
A defensible comparison starts from the work as it exists today. List each cleaning task — range hoods and filters, stovetops and griddles, the floor under the cook line, the mixers and kettles in the prep area, the dish area, the walls near the fryers. For each task write down who does it, how long it takes, how often it is scheduled, and what the crew has to touch to finish it. That list is your baseline. Without it, any equipment claim you read is impossible to check against your own operation.
Map who actually does each task today
In most central kitchens the same crew absorbs kitchen cleaning alongside production, which hides the real labour cost. Pull the numbers apart before you compare vendors:
- Direct time: minutes from the moment a worker picks up a tool until they put it away, including soaking, scrubbing, rinsing and re-wiping.
- Indirect time: filling buckets, fetching and diluting chemicals, moving to a mop sink, waiting for a degreaser to dwell, and drying surfaces before they can be used again.
- Rework: tasks that get done twice because grease film survived the first pass, or because a supervisor rejected a line during inspection.
- Constraint time: work that cannot happen during service, so it lands on the overnight crew and drags into the next morning.
Write the total as labour-hours per week per task, not as "two cleaners". A commissary usually has three crews with very different availability — the day production team, the evening finishing team, and a small overnight maintenance crew — and the comparison only becomes useful when each task is assigned to a specific crew and a specific window.
Break the job into elements you can price
Cleaning labour is easier to compare once it is decomposed. For every task, score six elements:
- Preparation — disassembly, covering nearby equipment, moving carts and pans out of the way.
- Chemical handling — storage, dilution, application, dwell time, and disposal.
- Mechanical effort — scrubbing, pressure washing, and how far the crew walks with a loaded bucket or hose.
- Rinsing and drying — how much water and how much wiping the surface needs before it is back in service.
- Verification — the supervisor walk-through and any record the food-safety programme requires.
- Re-entry — how quickly the line can restart, which is what a production planner really cares about.
High-temperature steam changes specific elements, not all of them. It reduces the dwell-and-scrub cycle on baked-on grease, shortens the rinse step because there is no detergent film to wash off, and leaves a hot surface that dries fast enough to reopen sooner. It does not reduce preparation or verification. That is exactly why the equipment comparison must be task-level: a machine can be excellent on one element and irrelevant on another.
Score three staffing models on the same worksheet
Once the elements are priced, put three staffing models side by side on one sheet:
- Model A — existing crew, existing method. Baseline. Highest scrubbing effort, chemical purchase and storage, and the most rework on heavy grease.
- Model B — fixed machine at a station. A central kitchen degreasing unit such as the fixed PowerDe HW02 sits on a power supply with an onboard tank and switches between dry and wet steam, so the crew works from one position with a hose and nozzle instead of carrying water to the task. The same model also covers vacuum work and engine-compartment style jobs on the site's own product page, so confirm the intended application scope for your equipment list before assuming coverage.
- Model C — mobile crew, machine moves to the task. A hand-pushed unit such as the PowerDe HMW3 runs on a 48 V battery and moves through the kitchen, which matters when cleaning is spread across rooms and corridors rather than concentrated at one line.
For each model, record hours saved per task, whether the task can be finished inside one shift, and how much chemical purchase and storage disappears. Teams comparing central commercial kitchen degreasing machine options usually find the fixed-versus-mobile question matters more than raw power: the deciding factor is whether your crews walk the machine to the job or bring the job to the machine.
Test the comparison with one line and one shift
Do not commit to a fleet decision on paper. Pick the worst line in the commissary — usually the fryer and range-hood zone — and run one shift with the candidate machine under supervision. Then measure the same four numbers you recorded for the baseline: elapsed minutes, number of people involved, number of times the task had to be repeated, and whether the line reopened inside the window the production planner expects.
Ask the supplier two practical questions during the trial. First, what does their PowerDe cleaning equipment range require for routine servicing — tank descaling, filter changes, nozzle and hose replacement — and how often, because maintenance hours are part of the labour comparison and are frequently left out of it. Second, which tasks are genuinely within scope for the specific model on the datasheet you are quoting. PowerDe's published cleaning range covers ten machines, from fixed 220 V units to driving-style and hand-pushed battery models, and the listed applications on the individual product pages are not identical; treat the page for the exact model as the authority, and confirm anything you intend to rely on in a contract.
The output of that single shift is a comparison you can defend to a finance reviewer: labour-hours removed, chemical handling removed, rework removed, and the reopening window you achieved — with the machine as one line in the calculation rather than the whole argument. Buyers who need a configuration beyond the published models can raise it directly at contact, since PowerDe lists equipment customization among its services.
