A site that has chosen the model still has to decide what arrives with it. For a hand-pushed steam cleaning machine, the supplier may deliver the unit on its own, or the unit together with the battery pack that feeds it. That single difference changes what the site has to buy locally, what the supplier configures, and what fails on the first week of operation. The sections below walk through the information a supplier needs, and the questions a purchasing or maintenance team should put back to them.
What the catalogue already confirms about the PowerDe HMW3
The hand-pushed steam cleaning machine is listed in two configurations: one supplied without the battery and one supplied with it. The parameter table on the without-battery page records the machine as PowerDe HMW3 (battery not included), with hand-push movement, overall dimensions of L1150 x W520 x H1030 mm, a 4.5 kW PTC semiconductor heater, a 50 L clean-water tank, a tap-water inlet with a 4-point internal-tooth fitting, dry steam and wet steam modes, a 48 V battery working supply, and a high-pressure water gun with nozzle. Treat those rows as what the page states, and confirm them on the quotation before ordering, because a quotation can add or drop lines.
The same page does not publish steam temperature, steam pressure, battery capacity, run time per charge, charger output, machine weight, hose and wand lengths, the accessory list, noise level, or water use per hour. A supplier configuring the machine for your site should be asked to state those values in writing rather than left to assume them, and none of them should be carried over from a different model in the cleaning equipment series, which includes fixed, battery-fed and driving-style machines with different supplies and different published rows.
What "without battery" actually decides for your site
Ordering the unit without the battery does not remove the battery from the system. The parameter table names 48 V battery working supply for this machine, so the energy source still has to exist somewhere. What changes is who provides it and who is accountable for it. Three practical consequences follow, and each one should appear in the order documentation so nobody discovers it at handover:
- The supply chain splits. The machine and its 4.5 kW heater arrive from the equipment supplier; a 48 V source, and any charger or cabling needed to keep it charged, comes from someone else unless the order says otherwise.
- Warranty and fault ownership split with it. When the machine stops drawing power, the site needs a written rule on which supplier investigates the machine side and which answers for the pack, connector and charge equipment.
- Site work grows. Storage, charging location, cable routing in a wet area and operator training all sit with the site, not the equipment supplier, unless the order includes them.
A team that wants a single accountable party usually asks for the battery-included configuration and has the supplier configure the whole working supply. A team that already stocks and maintains 48 V packs may prefer the shorter delivery of the machine alone. That is a procurement decision, not a technical one, and it should be made before the specification is sent out.
Information the supplier needs to size the configuration
Send the same facts to every bidder so their answers can be compared. The list below is what a manufacturer of cleaning machinery needs in order to configure a hand-pushed unit rather than recommend something else. The customer-facing team at Shenzhen PowerDe Automation Precision Equipment will ask variants of the same questions.
- Where the work happens: indoor or outdoor, floor type, gradients, door and lift widths, and whether the L1150 x W520 x H1030 mm footprint will pass every route between storage and the work face.
- The job being cleaned, and how often. Which surfaces, how heavy the soiling is, how many square metres per shift, and whether the task runs inside a shift window or after hours.
- Water at the point of use: whether a tap can reach the machine, the thread and fitting needed against the 4-point internal-tooth inlet, water hardness, and where the run-off will drain.
- Power and charging: whether the site will provide a 48 V source and a charging place, or whether the order should include them, and what the site's rules are for charging in that area.
- Who operates it, and how many: existing staff or a contractor, what induction they need, and whether the site needs written operating instructions in its own language.
Configuration items to fix in writing before the order
Once the machine model is agreed, the following lines decide whether the site can start using it on day one. Put each one in the purchase document as included or excluded, with the party responsible named.
- Energy: is the 48 V pack, its charger and its cabling in the supplier's scope or the site's? Ask for the pack capacity, run time per charge and charger output to be stated rather than assumed, since the page does not publish them.
- Water: confirm the inlet fitting against the site tap, ask whether a feed hose and strainer are supplied, and agree who supplies anything not in the box.
- Wands and nozzles: the parameter table names a high-pressure water gun with nozzle. Ask which nozzles are included for the surfaces you actually clean, and what the wider accessory list is, because that list is not published.
- Service and spares: response time, what is covered after handover, which consumable and wear items you should hold, and how a fault is reported. If the pack is not the supplier's, ask what they will and will not answer for.
- Documentation and training: operating instructions, the mode-selection guidance for dry and wet steam, and whether an on-site walk-through is offered at handover.
Questions to put back to the supplier
These are the questions that expose gaps between a catalogue row and a working machine. Send them to every bidder in the same wording so the replies line up side by side.
- If we order without the battery, what exactly do you deliver, and what must we have on site before the machine can run?
- What is the battery capacity, run time per charge and charger output for the battery-fed configuration, and where are those figures documented?
- What steam temperature and pressure does this machine deliver, and how were they measured?
- How long can it run on a full 50 L tank at our duty, and what is the water use per hour on the mode we will use?
- Can we trial the machine on our own surfaces before ordering, and what would a trial record need to show?
Checking the machine on site before it becomes the standard
Delivery is not acceptance. Run one short, recorded session on a surface that matters, with the site's own operator, and write down what happened in the site's own terms: the area covered, refills needed, whether the pack lasted the shift or needed charging mid-task, whether the water inlet reached the taps actually available, and whether the machine passed the routes it will use every day. Compare that record with the figures the supplier stated, and keep both documents. If the difference is material, raise it before sign-off, while configuration changes are still cheap.
A supplier that answers these points with written figures and a clear split of responsibilities has made the decision easy. One that answers with a model name and a price has not. Where a site's duties fall outside what a hand-pushed machine is listed for, ask the supplier to configure the equipment for your application instead of forcing the nearest catalogue item, and keep the trial record as the basis for the final choice.
