The mop says it works on sealed floors. The flooring carton says waterproof. Those statements still do not tell you whether this combination is approved. Find the collection name and product code before treating the whole kitchen as a test area.
Start by identifying the floor
NWFA: wood floor maintenance advises against steam mops on wood floors. A wood-look surface might instead be laminate or vinyl, so check an invoice or spare carton rather than guessing from the grain. Do not peel a corner or scrape the surface to identify it. If the floor came with the house, the retailer or manufacturer may be able to help from existing edge photographs and labels.
Distinguish damp, wet and steam cleaning
Permission for one method is not permission for all three. For example, Pergo's XP+ Catalina Acacia page expressly discusses wet mopping; that wording alone does not establish steam approval. Look for the exact care document and any restrictions on equipment, settings, dwell time, seams and damaged areas. The mop manufacturer's general compatibility list cannot change the floor warranty.
Product identity
Find the flooring brand, collection and code.
Permitted method
Read the current care instructions for an explicit steam statement.
Condition check
Inspect open seams, worn coating or damage before cleaning.
Approved routine
Use the specified cleaner and method; keep the instructions for later.
A less aggressive clean is a useful first move
Remove loose grit using a method suited to the surface, then spot-clean according to the flooring instructions. Use the recommended amount of cleaner; more product can leave more residue. A dull floor does not necessarily need hotter water. If it stays cloudy, investigate product buildup or finish wear before upgrading the cleaning force.
Stop if the surface changes
New haze, peeling, raised edges or opening seams after cleaning are reasons to stop and document the change. Let the manufacturer or installer assess it before adding polish to hide the effect. Keep the cleaning product and equipment details with your photographs. White marks and dark stains need a different repair discussion from an ordinarily dirty floor.
