Before using a steam mop on wood or laminate floors
Steam can force moisture into flooring seams. Check the flooring maker's specific permission before use.
A steam mop exposes flooring to hot vapor even if little standing water is visible. Pergo warns that steam pressure can drive moisture into seams, damaging layered flooring, and recommends vacuuming and lightly damp mopping instead. Shaw explicitly advises against wet or steam mops for its hardwood. Follow the exact floor manufacturer's rules, not general steam-mop marketing.
