Superheated dry vapor

Easily kill germs, bacteria, viruses and eliminate mold, dust mites and all other pathogens using nothing but the most natural cleaning method – superheated steam. At the heart of the ONE Plus™ steam cleaner is a highly-efficient heating element that pressurizes the stainless steel boiler up to 4 times the atmospheric pressure. The resulting low-moisture steam is then superheated up to 320ºF / 160°C – perfect for cleaning and disinfection.

The ONE Plus™ steam cleaner – nothing but the best.

The ONE Plus™ was engineered with top quality Italian and German components.
Assembled by hand in Europe, the ONE Plus™ steam cleaner comes with the best warranty available:

a lifetime warranty on the boiler and 3 years on the system

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.

Automatic shut-off

The heating element will automatically shut off when the water level drops below the minimum threshold. Your steam cleaner is instantly ready to go once you refill the water tank.



Four levels of safety ensure that your steam cleaner will always operate safely. These levels include the low water light, the automatic shut-off, a pressurized safety cap with a built-in blowoff valve and a childproof safety lock.
