The Jet Vac Alpha Steam Cleaning Machine is our entry level vacuumated steam cleaner and is built to the same high standards as the rest of the Duplex range using the highest quality components and processes. Duplex steam cleaners use super-heated water, also known as dry steam vapour. The vapour contains only about 5% water. The Jet Vac Alpha’s stainless steel boiler has a capacity of 1.5 litres and a 2.5 litre water tank. Being continuous flow allows automatic refilling and non-stop operation for maximum efficiency.Duplex steam cleaners take this technology a step further by managing internal boiler tank refills very precisely with a patented electro-mechanical innovation. The result is a steam machine that avoids large variations in pressure and temperature during use. The Jet Vac Alpha, like all the other models in the range is supplied with a range of tools and accessories that allow the operator to quickly and simply perform a multitude of cleaning tasks which were previously difficult and time-consuming. All Jet Vac models include an integral vacuum which further speeds up cleaning by removing dislodged dirt without the separate task of wiping it away with a cloth or mop. The vacuum function also removes allergens and dust.
