Tooling and workholding — vises, chucks, fixtures, tombstones, clamps, locators and the coolant hoses that feed them — collect a film that is part cutting fluid, part fine swarf and part way-oil mist. Left in place it hardens into a grit paste that shows up later as clamp faces that no longer seat flat, dowel pins that a part will not start onto, and fixture bolts that seize. Cleaning it is not a housekeeping item; it is part of holding accuracy. Before comparing PowerDe cleaning equipment, write the questions below down and take them to the supplier, because on this duty the accessory set and the mode selection decide the result more than the rated power.
Which nozzles and brushes are included
Ask for the full accessory list, not the marketing bullet points. On a machine-table cleaning job you want a narrow point jet for clamp pockets, bolt heads, T-slots and the gap under a fixture base; a wider fan jet for the table land and the tops of tombstones; and a stiff brush for the workholding faces, because a jet alone pushes swarf into the interface rather than off it. Then confirm what is not on the list: extension lances for reaching the far side of a large fixture, and any nozzle that is close to a spray pattern wide enough to soak an enclosure. Ask for the thread sizes of the nozzle connections and whether spare nozzles and brushes are stocked, since worn nozzles change the pattern first and nobody notices.
Whether the machine switches between dry and wet steam
Ask this before asking about power. Dry steam is what softens cured coolant residue and oil film on a fixture you do not want to flood; wet steam or hot water is what carries the loosened residue off the surface. A single mode leaves half the job undone. Hand-pushed units in the hand-pushed steam cleaning machine line switch between dry and wet steam; the mobile units that run on battery add a hot-water mode as a third setting. That difference matters in a bay with no floor drain, where every extra litre is a bucket and a mop afterwards.
How the run-off will be collected and where the water comes from
Two site questions follow directly from the accessories. First, whether the machine has a tank fed from a tap or needs a hose run and how long that run is — a fixed unit such as the HW02 is specified with an 80 L SUS304 tank and a tap-water inlet, and the tank only sets how long you can work before a refill, not how much run-off the job creates. Second, whether an extraction attachment is offered, so the emulsified coolant and swarf slurry is lifted off the table instead of draining into the enclosure, the ways or the chip conveyor. For a shop that cleans beside a machine rather than in a wash bay, ask about the extraction option by name; the published listings do not state a vacuum attachment for every model.
What stays off the list of things to spray
A high-temperature jet will not respect a scale. Rulers, glass scales, encoder cables, spindle seals, bearings, wiper seals, and any lubricated surface should be masked or cleaned with a cloth and a brush instead. The same caution applies to a machine or fixture with a coating, anodising, or painted surfaces: test one small hidden area first, because heat plus pressure can lift a finish that has already been attacked by coolant. Ask the supplier what the machine's published steam temperature is — HW02 is published at 160° at 0.8 MPa — and confirm what that means for the materials on your fixtures before the first full pass.
Send the fixture, not just the floor area
The questions above only make sense against your own conditions, so tell us what you actually clean: fixture and workholding types, the material of the fixtures, coolant chemistry and how heavily it is used, swarf type, the space you have around the machine, drainage, and the available power supply. With that we can confirm which machine and which accessories fit, and say plainly where this type of equipment is not the right answer, before you commit to a purchase.
