Which model designation applies to the fixed machine you are quoting
The first comparison question is a name question, and it matters because the fixed unit is listed in more than one way. The product page is titled "Fixed Steam Cleaning Machine PowerDe HW03", the parameter table gives the model as "PowerDe HW03 (220V)", and the overview text on the same page refers to "PowerDeHMW3 (220V)". A supplier quotation, an order form and a spare-parts request can each carry a different one of those strings, and a mismatch is how a buyer ends up with parts for a different chassis.
Write into your own document, in one line, exactly which designation your quotation applies to, and ask the supplier to confirm the same string in writing before the order. Then check it against the nameplate picture on the page, which shows the machine from the front and the rear. If the supplier's answer drifts to another fixed model in the cleaning equipment series, you are no longer comparing the same machine and the rest of your comparison is worthless.
What is the footprint including handles, and how much clearance does your space add
The specification table on the fixed-machine page gives machine dimensions of L1150 mm * W520 mm * H1030 mm, and lists the mode of movement as hand push. Treat those numbers as the envelope of the machine, not as the envelope of the installation. The real question for a fixed station is how much room the machine occupies once the hose is connected, the water line reaches it, and an operator can still stand beside it.
| Footprint item to compare | What to ask the supplier |
|---|---|
| Envelope on the page | Does the published L1150 mm * W520 mm * H1030 mm include handles, hose reel and any protruding parts on the unit being quoted? |
| Route to the station | Since the unit is hand-pushed, what doorway width and turning space does it need on the route from storage to the fixed position? |
| Working clearance | How much floor around the machine must stay clear for the operator, the water inlet connection and the water gun hose? |
| Reach of the cleaning tool | The page lists a high-pressure water gun with nozzle; what hose and wand lengths are fitted, and how far from the machine can an operator work? |
Measure your own space before asking. Take the doorway, the corner radius and the distance from the intended position to the wall, and put those measurements next to the supplier's answers. A footprint that is accepted without the route being checked is the most common way a fixed machine arrives and never reaches the position it was bought for.
Is the water supply a tap connection or a tank you refill
This is where two fixed machines that look identical in a quotation can behave very differently on your floor. The fixed-machine page records a 50 L box volume described as a clean water tank, and a water inlet method of tap water inflow with a 4-point internal tooth joint. Heating power is given as 4.5 KW with semiconductor heating, and the working voltage as 220V.
Those entries open four comparison questions, and none of them can be answered from the page alone:
- Does the unit you are quoting connect to a tap line, or does it run from its own tank between refills, or both?
- What thread and fitting does the inlet need, and does your plumbing already provide that joint or does the installation have to add an adapter?
- If you run from the tank, how many minutes of cleaning does one fill support in your duty cycle, and who refills it during a shift?
- What water quality does the machine expect, since the inlet is described as tap water, and does your site water need any treatment first?
Ask for the answers as numbers you can put in a spreadsheet: inlet fitting type, tank volume, and the working window per fill for the cleaning mode you plan to use. The page does not publish a consumption rate or a runtime, so a supplier who quotes one of those figures is giving you their own test result, not a catalogue value. Record who said it and under what conditions, because two buyers comparing the same machine will otherwise compare two different sets of assumptions.
How the steam mode changes the capacity you need
The fixed machine is listed with two cleaning modes, dry steam and wet steam, which is the feature that decides how much water capacity a given job consumes. Dry-steam work puts a smaller water load on each minute of cleaning than wet-steam work, so a buyer who plans mainly dry-steam tasks can accept a different refill pattern than one whose tasks are wet-steam tasks. The page confirms that the two modes exist on this machine; it does not publish the steam temperature or the steam pressure for it, and those two figures should be asked for rather than assumed from a similar model.
The practical comparison here is a duty-cycle question rather than a specification question. Describe your actual task to the supplier: the surface, how often you clean it, how long a session lasts, and whether the staff who do the work have ever run a steam machine before. Then ask which of the two modes that task belongs to, and size the water supply around the answer. If your tasks do not match what the fixed machine's listed use covers, say so in the same enquiry; the company behind the machine also develops customised equipment, and an engineering enquiry about customised steam cleaning equipment is the route to a configuration that fits your process instead of the other way round.
How to check the comparison after the quotation arrives
Before you choose between two quotations, put the same four blocks side by side on one page: the confirmed model designation, the footprint including handles plus your own clearance measurements, the inlet arrangement and the working window per fill, and the mode the supplier assigns to your task. Any block a supplier leaves blank is not a lower price; it is an unknown that will show up as an installation cost or a stalled cleaning job.
Then close the loop with a trial on your own floor. Run the machine through one real session at your position, with your water connection and your staff, and write down what the fill lasted, how the machine reached the position, and what had to be added to make the connection work. Those notes are worth more than the specification column, because they are the only figures measured on the site where the machine will actually live.
Shenzhen PowerDe Automation Precision Equipment Co., Ltd. publishes the fixed-machine parameters and the contact details for a quotation or a trial on its own pages, including the address in Longhua District, Shenzhen, the telephone number and sales@powerde.net.
