No, the Dyson WashG1 is not a steam mop and does not reflect the same process. This is Dyson’s first wet floor cleaner design, which picks up both wet and dry debris. The WashG1 has two rollers for even water application – however the water is not heated and does not produce vapour as a steam mop would. Often it is thought that hot water helps to kill bacteria but the water used when wet cleaning is normally not hot enough to effectively kill bacteria. Dyson WashG1 uses high density microfibre to agitate stains and the extraction technology removes dirty water rather than smearing it across the floor. You can use water up to 35° Celsius in the clean water tank of the Dyson WashG1.
