Choose Tineco S9 Artist Steam for cordless steam with powered maneuvering and a documented 30-minute Steam maximum. Choose S6 Stretch Steam for a longer session near outlets. S7 Stretch Steam provides cordless lie-flat steam, with a lower dirty-water limit when flat.
Compare cordless and corded steam floor washers using steam-specific runtime and floor compatibility. Keep hot dock cleaning separate from floor steam.

What matters in practice
Check floor permission first, then plan around the steam-mode battery limit.
3 of the 20 selected models have a documented floor-steam mode. 1 of those is corded. A heated roller wash or hot-air drying cycle does not put a machine on this steam shortlist.
S9 Artist Steam lists 75 minutes in lie-flat Auto mode and 30 minutes in Steam. Its Steam maximum is 40% of the Auto maximum. If your own steam routine takes 40 minutes, a corded S6 removes that battery constraint, though refills and emptying still interrupt the work.
A floor may tolerate damp washing but prohibit steam. Follow the flooring maker’s instructions, particularly around joints and finishes. The internal heater temperature is not a verified temperature at every point on the floor, and no sanitizing performance is claimed here.
