Kitchen staff rarely object to mopping the floor itself. They object to what happens before the mop touches the ground: scraping, spraying a degreaser, waiting for it to work, scrubbing the slurry, then squeegeeing and rinsing. By the time the floor looks dry, the shift is over. That sequence is hard to estimate because much of the time goes on chemicals waiting to react rather than on the floor. A usable estimate starts with the area, then adds the fixed setup and hand-work minutes around it.
1. Measure the floor you actually clean
Write down the flat area in square metres, then measure the harder zones separately, because each surface type takes its own method and its own time:
- Open floor between the line, the prep benches and the dish return
- Tile upstands and splash walls beside the ranges and the fryers
- Drain channels, floor gullies and the inserts sitting inside them
- The band around equipment legs, castors and wall bases, where grease seals the joint
Two kitchens with the same footprint can need very different time. A kitchen with a plain tile floor and one straight drain line is quick. A kitchen with a textured floor, deep channels and a lot of equipment standing on the floor takes longer, because grease hides in the joints and under the castors. Measure the floor as it is, not as it appears on the layout drawing.
2. Grade the grease first
Floor size sets the scale of the job; the condition of the grease decides the method. Check it with a fingertip and a white cloth, and write down what you find:
- Fresh film: soft, comes off onto the cloth, nothing built up in the joints. One pass takes it.
- Worked-in film: tacky and dark, visible along wall bases and drain edges. It needs heat at the point of contact, not just a hot mop bucket.
- Hardened coating: dry to the touch and sticky underneath, and it does not move under a scraper. This is where a nightly routine stops being enough.
The grade changes the estimate: a floor cleaned every night while the film is still soft is a different job from the same floor left for a month. If the team spends longer on the floor each week with no change to the menu or the equipment, the deposit has thickened, and the cleaning method rather than the rota is what needs review.
3. Time the real steps, not the ideal ones
Break the job into tasks and put a stopwatch on them once during a normal close, not on a quiet afternoon. Typical line items:
- Clear the area, move trolleys and bins, protect the electrical points
- Sweep or squeegee loose debris into the drain
- Treat the joints, gullies and wall bases
- Waiting for the detergent to work
- Agitation with a brush, a pad, or a lance and nozzle
- Lift the loosened grease, then rinse
- Squeegee and dry enough to be safe underfoot
- Wash the tools, empty the tanks, store the machine
Waiting time and tool handling are the two lines kitchens leave out of the schedule. Waiting is dead time on the clock but real time in the kitchen. Washing up at the end of a shift also costs time that never appears in the rota. Record both before you set a standard.
4. A planning worksheet you can finish in one shift
Do not look for an industry-average figure; it does not transfer between kitchens. Build your own rate from your own timings:
- Total minutes from the timed run.
- Subtract the fixed setup and pack-down minutes, which do not grow with area.
- Divide the remainder by the measured square metres to get a per-square-metre rate.
- For a new or enlarged kitchen, multiply the new area by that rate and add the fixed minutes back.
Keep the fixed minutes and the per-square-metre rate apart. A large central kitchen is not five times the job of a small restaurant kitchen, because the setup, the tool wash and the safety cordon are much the same either way. Separating the two is what keeps the estimate sound when a second site opens.
5. Where heat changes the estimate
The longest line in most worksheets is the waiting: the soak, the detergent, the pause, the scrub. Commercial kitchen floor steam cleaning puts heat at the point of contact instead of leaving detergent sitting on the tile. The Fixed Steam Cleaning Machine PowerDe HW02 is a fixed 220 V unit with dry and wet steam modes and a high-pressure gun with a nozzle, so the operator works the jet along the joint, the gully and the wall base rather than flooding the whole floor and walking away.
For planning purposes that moves three worksheet lines. The waiting drops away. Rinsing shortens, because less detergent means less to wash off and less left underfoot. The commercial kitchen floor degreasing pass on joints and gullies becomes a targeted task rather than a full-floor soak. Water use and the drying time afterwards fall with it, which matters on a tiled floor that has to be safe to walk on before the next shift.
The machine runs on a fixed 220 V supply and carries its own tank, so plan where it will stand, where the water inlet is, and how the hose reaches the far corner. A unit parked at one end of a long, narrow kitchen loses minutes to hose drags that never show up in a per-square-metre rate.
6. Turn the estimate into a schedule
Publish two figures rather than one: the standard nightly close, and a deeper weekly or monthly task for wall bases, gullies and equipment feet. Put the same task list on the wall, in the same order, every night. Once the list is fixed, the variation between shifts becomes visible, and you can tell whether a slow close came from the floor or from the rota.
Read the grade again beside the figure once a month. A kitchen that grades as fresh film after every close is running a schedule that works. A kitchen still grading as worked-in film at the end of the week is not short-staffed; it is using a method that cannot break the deposit down. That is the point at which an equipment review, not another rota change, is the right response.
If your timings show most of the minutes going on waiting, scrubbing and rinsing, PowerDe's Cleaning Equipment Series is worth a conversation. Bring the area measurement, the grade you recorded and the worksheet, and ask for a configuration matched to your kitchen layout.
