What the catalogue already answers, and what it leaves open
PowerDe's cleaning range is listed as a set of PowerDe cleaning equipment, and the hand-pushed members of that range are catalogued as a high-temperature, high-pressure machine offering dry-steam and wet-steam modes, listed both with and without a battery. The detail page for one hand-pushed configuration records the physical and utility rows a preparation sheet needs first: overall dimensions of L1150 x W520 x H1030 mm, movement by hand push, a 4.5 kW PTC semiconductor heater, a 50 L clean-water tank given as the box volume, a tap-water inlet with a 4-point internal-tooth fitting, dry and wet steam, a 48 V battery working supply, and cleaning by a high-pressure water gun with a nozzle. That page carries the model designation for a configuration supplied without a battery, while the range is catalogued with the battery fitted as a separate entry; the configuration named in this article is the battery-fitted one, so every row quoted below has to be reconfirmed against the battery-fitted listing before it is used as a site record.
Read that list as a starting position, not as a finished specification. The same page does not publish the steam temperature or steam pressure for that machine, the battery capacity, the run time obtainable from one charge, the charger output, the weight of the unit, the length of the hose and wand, the accessory list, the noise level, or the water consumed per hour. Those are the figures a cleaning team actually plans against, so the first preparation task is a written request to the supplier for them, for the exact unit being quoted, before anyone drafts a shift plan. A row borrowed from a different model in the same range will not describe the machine standing in the doorway.
Where the machine will be pushed, and what that path demands
Preparation is mostly a walking exercise. Take the recorded footprint of the hand-pushed configuration and walk it, physically, along every route the team would take: door widths and the clear opening once the door is held open, threshold lips and drainage falls, the turning space at the far end of a corridor, lifts and their internal dimensions, ramps, and any floor that is wet, grated, or sloped. A machine that clears a doorway in a straight line can still fail the job at the turn. Record, for each route, the distance from the working surfaces to the nearest water supply, the nearest power point, and a place the run-off can be routed to.
The 50 L tank on the recorded page is a carried volume, not a statement of how long a session lasts. How far the team can work before refilling depends on the water actually used, and that figure is not published. The same is true of the machine's reach, which depends on hose and wand lengths that the page does not list. Both belong in the written question list, and both change the walking route: a short hose means the unit is repositioned repeatedly, which turns a single-person job into a two-person job on some floors.
The battery changes which questions the team has to answer
A battery working supply removes the cable from the route. It does not remove the power requirement; it moves it to a charging arrangement that has to exist before the first shift. Because the page does not state battery capacity, run time per charge, charger output, or how the machine behaves as the charge runs down, those four items are the core of the written request, together with the replacement or spare-battery arrangement if one exists and the warranty and service terms that attach to the battery as a wearing item.
With those answers missing, plan conservatively and say so in the plan. Split the shift so that no single cleaning task is longer than the shortest charge the supplier is willing to state in writing. Decide who owns the charge at the start of a shift, where the unit charges, whether the charging point is inside the working area or a walk away, how a charge is verified, and what the team does when the charge runs out mid-task. Then write the comparison: the same range is also catalogued without a battery, so the mains-fed configuration is the alternative. For that configuration the questions are about the supply point, the circuit, cable reach, and cable routing across a floor people walk on. The battery version trades those cable questions for charging-location, charge-verification, and battery-handling questions. Which trade is cheaper depends entirely on the site, and on whether the buyer intends to keep the machine working continuously in one area or to move it between separated areas.
Two further points follow from the catalogue rather than from assumption. First, the hand-pushed page records dry and wet steam modes only; the driving-style machines in the range are separately described with hot-water modes as well, so hot-water cleaning should not be assumed on the hand-pushed unit until the supplier confirms the mode set of the delivered machine. Second, a vacuum-suction row appears on the PWD02 detail page and not on the hand-pushed page, so vacuum capability must not be built into a preparation plan for the hand-pushed configuration without written confirmation. The hand-pushed steam cleaning machine page is the record to hold the supplier to, line by line.
The utilities the site has to provide before delivery
The water side is defined by the recorded inlet row, which calls for tap water through a 4-point internal-tooth fitting with a half-inch thread. Preparation means confirming that a tap of that description exists within reach of the routes mapped above, or booking the adaptation, and confirming who supplies the mating fitting and the hose. A machine delivered with an inlet that nothing on site matches stalls on the first day over a fitting that costs very little.
The electrical side needs a separate answer for the two halves of the system. The recorded 4.5 kW heater and the 48 V battery working supply sit on different paths, and neither tells a facility electrician what to install. Ask, in writing, for the supply voltage and current the delivered machine and its charger require, the plug or terminal arrangement, whether the heater and the charger may share a circuit, and any earthing, isolation, or residual-current requirement the supplier expects. Have a qualified electrician confirm the circuit before the machine arrives, including whether an existing socket is on a suitable circuit at the position the plan needs. Ask which protection functions the delivered machine includes, and how a tripped protection is reset on site, so the team knows what to do when a machine stops mid-shift rather than calling a supplier on the same afternoon.
Deciding what the team is actually asking it to clean
A preparation plan needs a surface list, not an intention. Write down each surface group the team expects to clean, the deposit on it, and how the team would currently know the result was achieved. Then check that list against the site's own published applications rather than against a general idea of what a steam machine does. The listing for the hand-pushed machines states cleaning and disinfecting of hospital beds and medical machinery, and that is the only application the page names for this type of machine. If the surfaces the team has in mind sit outside that wording, that is not a disqualification; it is a question to put to the supplier in writing, with photographs and the deposit description, and to settle with a trial before an order.
Write exclusions on the same sheet. Steam onto an electrical enclosure, a bearing, a lubricated surface, an unfinished or patched coating, a laminated or bonded assembly, or any surface carrying a warning against wet cleaning should sit outside the scope with a named alternative method. A preparation plan that lists only the intended work and not the excluded work will be judged afterwards on surfaces it never covered.
Running a bounded trial before the team depends on the machine
Most of the numbers a team wants are not published, which is exactly why a bounded trial does the work that a data sheet cannot. Set the trial up so that it produces evidence rather than an impression: two or three representative surface groups, each with the same starting condition; one operator trained once on the machine as delivered; dry steam on one area and wet steam on another, so the mode difference is visible on the same deposit; and a written record of the time spent, the number of passes, the water used, the distance walked back for refills, and the charge state at the end of the session. Fix the acceptance standard before the trial starts, in the form the team already uses to judge whether a surface is clean, and fix a stop condition so the trial cannot drift into an indefinite demonstration.
The trial also measures the battery question directly. If the machine is offered both with and without a battery, and the trial unit carries one, run the same session twice, once on a charge and once with the unit kept on its supply, and compare what the operator had to change. If the delivered unit has no battery, then the preparation list is not shorter but different, and the trial measures cable handling, reach, and the trip hazards a cable creates on a wet floor instead. Either way, keep the trial's own figures and do not merge them with figures taken from a product page; the plan will be used to write a standard for the machine actually on site.
The written questions to send before the shift is planned
Send one short list, and require written answers, for: the steam temperature and steam pressure of the delivered machine; the battery capacity, run time per charge, charger output, and end-of-charge behaviour; the weight of the unit and the hose and wand lengths; the accessory list supplied; the noise level; the water use per hour and the refill interval that follows from the carried tank; the supply voltage and current for the machine and charger and whether they may share a circuit; the mating water fitting required at the site tap; the protection functions included and how each is reset; the service and warranty terms for the battery; and the mode set confirmed for the delivered configuration. Alongside those, ask for the figures that describe the buyer's own case, since they are not on any page: whether the machine is offered for the surfaces on the surface list, what preparation the supplier expects of a team using that machine day after day, and what the supplier has seen work on that deposit before.
Turning the trial into a routine the team keeps
Once the trial closes, write the standard on one page and train it at the machine rather than in a room. The page should show the surface list with its mode and its exclusions, the route with its refill and run-off points, the charge routine, the personal protective equipment the operator wears, the checks done before the first task and at the end of a shift, the fault conditions the operator stops for, and the name of the person who maintains the machine. Shenzhen PowerDe Automation Precision Equipment describes its cleaning range alongside engineering and customisation services, so a buyer who needs the machine matched to a layout, a mode set, or a supply arrangement can take the surface list and the trial record straight into that conversation instead of starting again from a product card.
Review the page after a set date, with the trial figures beside it, and change the two lines that the trial disproved. A preparation plan for a battery-fed hand-pushed machine is worth keeping only if it records what this machine did on this floor, with the unpublished figures left as questions until the supplier answers them in writing.
