What a cloud kitchen is really cleaning
A delivery-only kitchen has no dining room to absorb its mess. Grease is the main soil, and it behaves in a predictable way. Warm grease is soft and moves; cooled grease hardens and bonds to metal. So the cleaning question is about heat and time. Anything that keeps the surface warm while it is being worked on removes the deposit with far less scrubbing. Anything that relies on cold water and detergent has to make up for the missing heat with dwell time, brushing, and rinsing.
Water handling is the second constraint. Cloud kitchens usually sit in low-rent commercial space with one or two floor drains, no dedicated wash bay, and shared utilities. A method that floods the floor creates a slip hazard, leaves standing water that has to be squeegeed to a drain, and can run under equipment into wiring and motor housings. This is where methods that look effective in an open yard start to fail indoors.
The five methods compared
- Manual scrubbing with detergent. Lowest equipment cost, and it works on light soil. It depends on labour the kitchen cannot spare at closing, and it is the slowest option on hardened grease.
- Cold-water pressure washing. Fast on a concrete floor or a stainless shelf in a loading area. Indoors it produces a large volume of run-off, and cold water does not soften grease, so the operator pressure-washes, scrubs, and washes again.
- Hot-water pressure washing. Heat plus impact does cut grease quickly and suits heavy floor and wall cleaning. The water volume is the drawback in a small kitchen with limited drainage.
- Foam and soak cleaning. Applying a grease-cutting foam and letting it dwell is useful for ducts, filters and dismantled parts, because the chemical does the work while staff move on to another task. It still needs a rinse and it leaves the kitchen wet.
- Steam cleaning. High-temperature steam carries heat onto the surface with very little free water, so the grease is lifted rather than blasted. Commercial kitchen steam cleaning suits hoods, hinged hood panels, griddle backsplash, fryer housings, oven doors and gaskets, trolley frames and the floor directly around the hot line.
A practical evaluation sheet
Write down five columns before any demo or trial, and fill them in yourself rather than accepting a supplier's figures.
- Time on the hot line. Time the same job — one hood panel, one fryer housing — with the current routine, then with the machine on trial. Compare clock time, not impressions.
- Water and run-off. Watch where the water goes and how long the floor takes to dry enough to cook on again.
- Chemical use. Note how much degreaser the routine consumes, and whether the method reduces it. Less chemical means fewer storage and handling questions.
- Labour fit. Ask whether the shift team can run the method at the end of a service without a specialist on site.
- Downtime. Record whether equipment has to be taken out of production, and for how long.
Run the trial on the dirtiest equipment you own, not on a clean demo surface. A method that looks good on a light panel may still be slow on a hood filter that has cooked for a week.
Where a fixed steam machine fits
For a kitchen that runs one hot line and cleans it at the end of every service, a stationary unit parked near that line is usually a better fit than a mobile one. The PowerDe HW02 steam cleaner is a fixed machine built for continuous service use. Its published parameters give an operator something concrete to test against: 220 V supply, 6 kW heating power, steam temperature of 160°, vapour pressure of 0.8 MPa, an 80 L SUS304 tank, and dry-steam and wet-steam modes. The dimensions, including handles, are 1,200 × 800 × 1,200 mm, and the water inlet is tap water through a 4-point internal-tooth joint (1/2 inch), so it connects to a normal kitchen water point instead of needing a plumbing change.
Read those numbers as a checklist. Whether 160° steam at 0.8 MPa clears your own grease deposit, and whether 6 kW matches your available supply, is verified in the trial, not by the datasheet. PowerDe lists the HW02 as a fixed machine for cleaning and disinfecting at service sites. Before ordering for a kitchen, ask the manufacturer to confirm duty-cycle and suitability for central kitchen degreasing in your specific layout, and ask them to state in writing on the quotation the figures the product page does not publish — steam output per hour, runtime per tank fill, weight, and the accessory set. The same request applies to any machine you are comparing, and a supplier who cannot answer it in writing is a supplier you should not buy from for a commercial kitchen.
Two methods, not one
Most cloud kitchens end up with a combination rather than a single winner. Steam handles the hot line: hood surfaces, griddle backsplash, fryer and oven exteriors, and the floor immediately around the cook line, where grease and slip risk build together. Soak and foam still make sense for parts that come off and can be moved away from the line, and a pressure washer is still the right tool for a loading bay or a heavy floor wash-down on the day the kitchen is closed. The comparison question is therefore narrower than it first appears: which daily, between-service tasks move to a lower-labour, lower-water method, and which occasional tasks stay with the equipment you already own.
Questions to put to a supplier
- Which published figures are measured values, and can they be supplied in writing with the quotation?
- Can the machine run continuously through a full clean-down, and what is the refill or recovery time?
- What nozzles and extension lengths are included, and are they stocked as spare parts?
- What training does a shift team need before running the machine unsupervised?
- For a fixed installation, what electrical supply and water connection is required at the position you intend to park it?
Operators who want that answer from the manufacturer rather than from a reseller can review the cleaning equipment range and send the kitchen layout and utility details to the engineering team at PowerDe cleaning equipment. Compare the methods on your own equipment, on your own shift, and on your own clock, and the choice usually makes itself obvious.
