Start with the floor build-up, not the machine
Walk the floor with the lights off and a work light low to the ground. Grease shows as a dull, smeared reflection that a mop has spread rather than removed. Note where it is thickest: usually in front of the range, the fryer and the dishwasher, and along the wall edges where the mop never reaches. Thick surface grease will not be lifted by steam alone; it needs to be scraped and removed with a degreaser first, otherwise the steam just emulsifies it and moves it somewhere else.
Then check what is under the grease. In a washdown kitchen the floor is normally ceramic or porcelain quarry tile, sealed concrete, or resin. Steam is applied with water at temperature, so the material and its joints matter more than the machine. Sealed or glazed tile with sound grout handles hot water well. A permeable substrate, old unsealed concrete, or a resin coating that has begun to soften is a different case, and the manufacturer of the floor covering should be asked before heat is applied.
Check the joints, the hollow tiles and the slope
Tap a handful of tiles across the room, including areas that look fine. A hollow sound means the adhesive bond has failed. A pressure stream of hot water can work under a tile that is already loose and turn one bad tile into a patch of bad tiles. Mark the hollow areas and plan to clean around them, or repair them before the steam work.
Grout and perimeter joints are the second check. Missing or crumbling grout lets water get behind the tile and into the substrate. Where a floor meets a wall, or where a coving strip has come away, look for gaps that open into the wall build-up. Hot water and steam will follow those gaps; they do not respect a boundary that the tile layer has already lost.
Third, check the drainage. Pour water on the floor and watch it. It should move toward the gullies and drains and leave no standing pools. A flat area that holds water means any wet cleaning method — steam included — will leave water sitting on the floor long after the work is done, which is how slip hazards and odour problems return.
Confirm the conditions around the floor
Electrical work comes first. Kitchens have low-level sockets, equipment flexes, and wiring runs near floor level. Before any wet work, confirm what is live, what can be isolated, and what must be protected. Cable trunking with a broken lid, a socket with a missing cover plate, or equipment sitting on the floor with its motor housing below socket height all need attention before water goes down.
Next, look at what is on the floor and what can be moved. Light equipment on feet can be lifted and moved; heavy ranges, refrigeration and extractor bases normally cannot. Where equipment cannot move, the floor around it has to be cleaned in sections, and the feet of the equipment should be checked afterwards for water that has collected under them. Non-slip performance should also be checked after cleaning, not just on the day of the work, because a floor that has been stripped of grease can behave differently underfoot than the floor staff were used to.
Match the machine to what the check found
A floor with intact joints, working drainage and heavy baked-on grease is the case where central kitchen degreasing with a fixed machine makes sense. The Fixed Steam Cleaning Machine PowerDe HW02 runs on a 220 V supply, with a 6 kW heater, an 80 L stainless tank and an outlet listed at 0.8 MPa — a stationary unit plumbed to a water supply rather than a portable canister you carry in and fill. PowerDe also builds battery-fed mobile units in the same Cleaning Equipment Series if the kitchen has no supply point at floor level, or if the work has to move between floors.
Whatever machine is chosen, one point decides whether the job is finished: how the loosened grease and water leave the floor. Steam lifts the soil; it does not remove it. Plan for a wet vacuum or squeegee and a route to drain it, and set the section sequence so the last area cleaned is the one you walk out through.
A short pre-start list
- Surface grease scraped and degreased before heat is applied.
- Tiles tapped for hollows; loose areas marked and avoided or repaired.
- Grout and perimeter joints sound, no open gaps into wall build-up.
- Water test run: floor falls to drains, no standing pools.
- Floor-covering material confirmed as suitable for hot water with its manufacturer.
- Low-level electrics isolated or protected; trunking covers intact.
- Extraction, water supply point and a route for the washdown water confirmed.
- Non-slip performance re-checked once the floor is dry.
If the check comes back clean, the floor is ready for steam. If it finds a lifting tile or a flat patch that ponds water, deal with the floor first and the machine second. Send the drainage layout, tile type and the size of the kitchen to the equipment supplier before specifying the unit, and the machine you get will fit the room rather than the brochure.
