Start from the floor plan, not from the machine
Write down the actual washing position first. In an indoor garage the machine normally works from a fixed corner and the operator walks the lance around the vehicle; in a narrow outdoor parking area the bay width, the driving aisle and the distance to the nearest water point all change the working radius. Note the width of the aisle, the turning space, and whether the surface is concrete, epoxy or paving — a wet-steam job on a smooth epoxy floor needs drainage planning that a rough concrete pad may not.
Then measure three distances on the drawing: from the planned stand-by position to the water inlet, to the power distribution point, and to the drain or floor gully. Those three numbers determine hose routing, cable length and whether the operator crosses a traffic lane while working. If a measured distance is shorter than the accessory length quoted on the product page, ask the supplier to confirm the hose and cable length before ordering rather than assuming a standard figure.
Power supply: the decisive item for the battery-free version
The battery-free PWD01 runs on mains power. Two things have to be verified at the site itself, not from memory:
- The available supply voltage at the socket or distribution box that will actually feed the machine, and whether it matches the working voltage stated for the unit. Site electrical in older garages is often 110 V or an unbalanced single phase where a 220 V circuit was assumed.
- The circuit capacity, including the heating load, with enough margin for a full shift of heating and restarts. A circuit that is adequate for a pressure washer may still trip when a steam generator holds its heating load for hours.
Because there is no on-board battery, the machine cannot be pushed out of the socket's reach. Count the number of outlets and cable runs between the stand-by point and every bay you intend to clean, and check whether the cable crosses a driving lane. If it does, either re-route the cable in a protected trunking or move the stand-by position. This is the single most common reason a battery-free steam machine ends up under-used.
Water: inlet quality, tank filling and the practical shift rhythm
The product listings for this series describe a tap-water inlet with a threaded fitting. Confirm two things on site: that a tap of the matching thread is reachable at the stand-by position, and that the water there is suitable for steam generation. Mains water in many industrial areas is hard; scale is the usual cause of lost steam output and more frequent servicing, so plan for water treatment or a defined descaling routine in the operating procedure.
Next, translate the tank into working time on your own shift pattern. Fill the tank, run a typical bay, and record how many vehicles you finish before a refill is needed and how long the refill plus heat-up takes. That measured figure — not a published claim — is what you put into the labour plan. Where the refill point is far from the machine, the hidden labour cost of walking and refilling is often larger than the difference between two candidate machines.
Movement: decide whether driving the unit across the site is required
The PWD01 is described as a mobile machine intended for indoor garages and narrow outdoor parking spaces. That wording is a useful test against your own layout: if your bays are separated by long distances, steps, kerbs or a change of floor level, the practical question is whether the machine travels with the operator or stays put while the hose and cable travel instead. Walk the route with a tape measure, and check door widths, thresholds and ramp gradients at the narrowest points.
Battery-free does not mean immobile: it means the supply line limits the working radius. If your workflow needs the unit to move freely between distant bays for a whole shift, compare the battery version of the same series against the fixed layout you have just measured, and let the measured distances — not preference — pick the variant.
Mode fit: dry steam, wet steam and hot water against your actual soil
The series is offered with dry-steam, wet-steam and hot-water modes. Match each mode to the soil and surface you actually deal with, and write that mapping into the operating instruction so new staff use the right setting:
- Engine-compartment style work and electrical or sensor-heavy areas: prefer the drier mode, keep the lance moving, and never treat steam as a substitute for covering sensitive parts first.
- Loosely soiled panels and routine exterior cleaning: the mode that rinses as it cleans is normally faster, at the cost of more run-off water to manage.
- Adherent grease and oil film: expect a two-step routine — soften with heat, then remove the residue mechanically — instead of expecting one pass to finish the job.
Run one supervised trial on your own worst soil condition and record the pass count and the time. That trial is the cheapest evidence you will get, and it is also the basis for the cleaning specification you hand to your team or to a client.
Safety, drainage and the paperwork around the site
High-temperature steam needs a written rule set before the first shift: who is allowed to hold the lance, what personal protection is required, how hot surfaces and standing steam are signposted, and what happens when the machine is left unattended. Related listings for this product family describe protection functions covering leakage, short circuit, high temperature, high voltage and water shortage; treat those as features to be verified for the exact unit you are quoted, and record which ones are present on your machine.
Drainage and run-off often decide a site's feasibility. Determine where the wash water goes, whether oil and grit must be intercepted, and whether your operating permit or landlord conditions restrict discharge from a garage or parking area. Fix the drainage answer before ordering the machine, because it is usually the most expensive thing to change afterwards.
Finally, close out the ventilation question for enclosed garages: steam plus a hot generator in a tight space needs air exchange, and the answer for a fully enclosed basement bay differs from an open-air parking row.
A short site-assessment sheet you can fill in on the visit
| Item to check | What good looks like |
|---|---|
| Stand-by position | One fixed point per working zone, out of the driving lane |
| Voltage and circuit | Measured at the actual socket, with heating load added and margin left |
| Water inlet | Thread matches, tap within hose reach, hardness known, treatment planned |
| Refill interval | Measured per bay on your own shift, including heat-up time |
| Route and access | Door widths, thresholds and ramps measured at the narrowest point |
| Drainage and permit | Discharge route agreed, interceptor fitted if required |
| Mode mapping | Each soil type assigned to a mode in a written instruction |
| Storage and drying | Covered, drained, hose coiled, out of weather and out of traffic |
If every line above is filled in with a measured value, the quotation you request from a supplier can be compared properly, and the installation day stops being a discovery exercise. If a line is blank, that is the item to resolve first.
Questions operators ask most often
Does the missing battery reduce cleaning power?
No. The battery version removes a cord dependency, not steam output. Judge cleaning effect by the mode you select, the technique and the soil condition; judge the battery-free version by whether a mains supply and cable route exist where you actually work.
When does the battery-free version make better sense?
Where the machine works from one or two fixed positions close to a suitable outlet — a single garage bay, a fixed corner of a service area — a mains-fed unit avoids battery charging routines and the weight of a battery pack. Where the crew moves across a wide site all day, a battery variant usually earns its price.
What should the trial cover before I order?
Run your worst soil condition, on your own floor, with the water you have, on the circuit you have. Record time per vehicle, refill count, cable handling problems and any trip or pressure drop. Bring that sheet when you talk to the supplier — it lets them confirm the right variant and accessory set instead of guessing.
Bring your measured layout — bay dimensions, supply voltage, water point and drainage route — to the supplier, and the discussion becomes a configuration decision rather than a guess. PowerDe cleaning equipment covers mobile, hand-pushed and fixed steam machines for garage, parking and facility work, and customized steam cleaning equipment can be discussed where a site layout needs a different supply or mounting arrangement.
