Electric low volume vapour steam cleaners run from either a 240v or 415v supply and heat the water with an element without the need for any other fuel source. This means that high temperature dry steam of up to 180ºC is produced in a clean zero emissions boiler and can be used inside. The steam production is lower therefore they are more suited to detail cleaning internally or where fumes are a problem.
Traditional cleaning methods remove dirt by apply water normally at pressure, but some dirt and bacteria can remain in the pores of the surface. Disinfectants also mainly act only on the surface, so bacteria can still survive even after a vagarious clean. High temperature vapour steam removes organic materials in all the pores of most surfaces leaving clean hygienic surfaces.
