Labour, not equipment, is usually the largest single cost in cleaning a fleet of delivery vans. A van is not difficult to clean, but there are many of them, they arrive in waves between routes, and the job has to be finished before the next shift takes the vehicle. Comparing labour needs therefore means comparing where minutes are actually spent, not estimating how long one van "should" take. This article sets out how a team can measure and compare labour requirements across methods, vehicles, and machines so the comparison holds up when the fleet size or the schedule changes.
What counts as labour on a delivery-van cleaning job
Most teams under-count labour because they time the nozzle and ignore everything around it. A usable comparison counts five blocks:
- Set-up and move: positioning the van, laying protection, connecting water and taking the machine to the working position, including how far the crew walks or repositions during the job.
- Actual cleaning time on the vehicle, split between the exterior faces, the load compartment, and the areas that need rework.
- Rework: the second pass on zones that did not release on the first.
- Recovery and clean-down: containing and handling wastewater, wiping down, and clearing the bay.
- Machine support time: refilling water, waiting for the machine to recover temperature or pressure, and any stoppage.
The last two blocks are where an under-specified machine quietly adds cost. A machine that cannot hold state through a vehicle transfers that time into block five, and the crew stands waiting.
How to measure the baseline honestly
Pick one method and one machine and time six to eight consecutive vans, on a normal day, with the normal crew. Record start and stop for each block above, plus the van type and how soiled it was on arrival using a simple three-level scale agreed in advance.
Time the crew, not the vehicle, when two people work at once: two people for ten minutes is twenty person-minutes. That single habit is what lets a later comparison be about people rather than about elapsed time, which matters when the constraint is shift coverage rather than bay availability.
Do not correct the numbers afterwards. A baseline that includes a slow morning and a stoppage is a truer baseline than a tidied one, because it reflects the schedule the team actually has to work to.
Which variables change labour most on van exteriors
When teams compare options, the differences in labour almost always come down to six factors, and they can be ranked by how much time they move:
Soil load on arrival is the largest, because it drives rework. Second is whether the method needs a pre-treatment step and its dwell time. Third is recovery: whether liquid is lifted as it is applied or left to be wiped or rinsed afterwards. Fourth is whether the machine holds its output continuously or interrupts the job. Fifth is whether the crew works in a fixed bay or moves a mobile unit around the vehicle. Sixth is the definition of "clean" the vehicle is released against - a tighter standard costs time, and the standard should be agreed rather than assumed.
A fixed installation changes the fourth and fifth factors directly. PowerDe's HW02 fixed steam cleaning machine, for example, is listed with a 220 V supply, 6 kW heating power, an 80 L SUS304 tank, 0.8 MPa working pressure, operation to 160 degrees C, dry-steam and wet-steam modes, and a vacuum recovery function. Those published functions determine whether the crew waits for recovery and whether a separate liquid-removal step is needed - the two biggest labour swing factors after soil load. Any comparison against a mobile unit should be made against the specific quoted configuration, and figures the listing does not publish should be confirmed with the supplier rather than estimated.
How to compare two methods without fooling yourself
Compare on person-minutes per van, split by the same five blocks, on vans of the same type with a similar soil-load distribution. Then compare the spread, not only the average: a method that averages 40 minutes but sometimes takes 90 is worse for shift planning than one that averages 45 and never exceeds 55.
Change one thing between trials. If a new machine and a new nozzle and a reorganised bay are introduced together, the result cannot be attributed and the next decision will be guesswork. Record the soil-load mix for each trial, because a method that looks faster may simply have been tested on lighter vans.
How the numbers should be used to plan a shift
Convert the comparison into vans per crew-hour at the observed spread, then plan against the worst realistic case rather than the average. Delivery vans arrive in bursts between routes, so a plan built on an average will fail at the exact moment the fleet needs the bay.
Keep the record visible to the crew. Teams that can see their own rework count per vehicle change behaviour faster than any instruction does, and a falling rework count is the cheapest labour saving available before buying equipment.
Frequently Asked Questions
How many vans need to be timed before the comparison means something? Six to eight per method is enough to see the pattern and the spread; fewer than that mostly measures who happened to be working.
Does a fixed machine always use less labour than a mobile one? Not always, but it removes two cost drivers: the crew moving the machine, and waiting for the machine to recover. That is why fleet operators with a permanent yard usually look at a fixed unit such as the fixed steam cleaning machine first.
What is the fastest way to reduce labour without new equipment? Reduce rework. Identify the zones that consistently need a second pass and change the technique or dwell time for those zones only.
Where do the machine's published figures come from? From the product pages across the cleaning equipment series, which state power, tank, temperature, and function data model by model.
Shenzhen PowerDe Technology Development Co., Ltd. has built cleaning and industrial equipment since 2007 and publishes the function data its machines are rated to, so that buyers can build labour comparisons on stated capability. As an intelligent cleaning equipment manufacturer, PowerDe expects fleet operators to bring their measured numbers and to confirm with the supplier anything the product page does not state.
