PowerDe's hand-pushed HMW3 is sold in two configurations: the battery-included machine and the HMW3 without battery. The machine itself is the same. The difference is what arrives in the crate and who owns the power source that drives it. Before you ask for a quotation on the no-battery version, it helps to be clear about what you are buying, what you still have to supply, and which of your sites that option actually suits.
Understand what the no-battery variant is missing
The HMW3 runs on 48 V. In the battery-included version that 48 V comes from an on-board pack, so the operator pushes the machine and starts work without stopping to find a socket. In the HMW3 without battery, the pack is left out. Everything else stays: the high-temperature, high-pressure steam generator, the dry-steam and wet-steam modes, the 4.5 kW PTC semiconductor heater, the 50 L clean-water tank filled from a standard tap, and the high-pressure water gun and nozzle used for the actual cleaning.
So the first selection criterion is simple and often skipped. Ask your team where the 48 V will come from. If your workshops already standardise on a 48 V platform, or if your cleaning machines are battery-swapped from a central charging room, the missing pack is not a problem. If nothing on site produces 48 V, buying the machine without one just creates a spare-part project you did not plan for.
Match the machine to the floor plan, not the datasheet
The HMW3 is a hand-push machine measuring 1,150 mm long, 520 mm wide and 1,030 mm high. That footprint is the reason it is specified for hospital beds and medical machinery, where a large fixed unit cannot follow the equipment and a hose run across a corridor is a hazard. It is also why the same machine works well in clinics, labs, care areas and any room where cleaning has to move from one piece of equipment to the next.
Write your own route before you choose the variant. Walk the areas that need cleaning and note the door widths, the lifts, the distance to the nearest water outlet, and how long one continuous job takes. A route of several rooms across a floor favours a self-powered machine. A single room, or a fixed bay where the machine parks between jobs, is where the no-battery version starts to make sense.
Decide how you want the power paid for
There are two honest ways to buy a cleaning machine, and the battery question is where they part.
- Shared fleet. If the same battery packs already circulate among your PowerDe cleaning equipment, buying the machine without a battery keeps the fleet interchangeable and avoids paying twice for capacity that sits idle when the machine is parked.
- Standalone unit. If the HMW3 will be the only machine in the building, or the only one of its type, buy it with the battery. A machine that cannot start without a pack you do not own is not a cheaper machine; it is an incomplete one.
Resellers and distributors usually buy the no-battery version deliberately, because their customers bring their own power arrangements and want the price broken down. End users who need the line running the week the machine arrives almost always want the battery included.
Check the consumables and site services before you compare prices
A quotation is only comparable when both suppliers are describing the same job. For the HMW3, confirm on your purchase order:
- Whether the 48 V supply interface, charger and cabling are included, priced separately, or expected from your side.
- The water connection. The machine takes tap water through a 4-point internal-tooth fitting, so your plumbing must match it.
- Which nozzles and wands you receive with the machine, and which you keep as spares.
- Who services the 4.5 kW heater and the pump assembly once the warranty period runs, and how quickly parts reach you.
Those four points usually cost more over five years than the difference between the two variants. Put them in writing while you are still comparing suppliers.
Use the steam modes as part of the decision
The HMW3 switches between dry steam and wet steam. Dry steam does the work where water is the problem: disinfecting a bed frame, treating a surface next to electronics, cleaning a room that has to be back in use quickly. Wet steam carries the heat further into a surface and suits items that can be cleaned thoroughly and then dried. If your work is mostly dry-steam disinfection around medical equipment, a compact hand-push machine is the right class. If your work is heavy grease on machinery or vehicle surfaces, a different steam cleaning machine in the range will serve you better, and the battery question becomes secondary.
Confirm the specifications you depend on
The published HMW3 page gives the machine dimensions, the hand-push mode of movement, the 4.5 kW PTC heating power, the 50 L tank, the tap-water inlet, the dry and wet steam modes, and the 48 V working supply. It does not publish steam temperature, steam pressure, battery capacity, runtime, charger output, weight, hose and wand lengths, the accessory list, noise level, or water consumption per hour. If your specification, tender document, or safety review needs any of those numbers, ask for them in writing before the order, rather than assuming a figure.
A short checklist before you order
- Do you already own 48 V packs that fit, or will the machine have to be powered another way?
- Can the machine reach every room through your doors and lifts at its 1,150 × 520 × 1,030 mm size?
- Is tap water with a 4-point internal-tooth fitting available where cleaning actually starts?
- Is your work mainly steam disinfection of equipment, or heavy soil that needs a larger machine?
- Are the missing technical figures supplied by the manufacturer before you sign?
Choose on the power arrangement and the floor plan, and the no-battery HMW3 becomes a deliberate purchase rather than a discount. Shenzhen PowerDe Automation Precision Equipment lists both configurations side by side, so you can specify the one that fits your operation; if your application needs a fixed unit or a larger mobile machine, the engineering team can be contacted through the contact page to review the setup.
