User Manual Rowenta DW5183U1 Focus Steam Iron, 1750 Watts

For irons, 1,500 watts is the minimum we recommend, and although the M400 doesn't give off as much steam as the 1,800-watt Rowenta SteamForce or the 1,600-watt Black+Decker Allure, it has performed better than many irons I've tried with more power. Some of that performance might be attributable to ergonomics.
