For instance do you want a hot or cold water pressure washer. In most situations a cold water version is adequate but a hot water washer with an integral boiler will remove stubborn residue more easily (just think about doing the washing up – hot water is much more effective). For even more cleaning power a hot water jet washer can have a facility to make steam which is achieved by a valve reducing the water flow into the boiler causing steam to be formed when leaving the lance. Steam is useful for cleaning very stubborn deposits as well as killing bacteria.
CST™ Continuous Steam Technology The ONE Plus™ steam cleaner was designed with a two-tank system. This technology means the water tank is not under pressure and can be refilled at any time eliminating downtime. Stainless steel boiler High-grade stainless steel is TIG welded together with a robotic welder to ensure the quality of the most solid and durable boiler on the market. This is why Dupray provides a lifetime warranty on its boilers – the heart of any steam cleaner.
