What is the difference between pressurised and on-pressurised?
Some manufacturers will use phrases such as “blast” dirt and grime away. The reality is somewhat different. We believe the cleaning power of steam is enough to clean virtually anything around the home. Pressurised steamers can reach pressures up to 4 Bar (70PSI), this is not really a high pressure; if you compare this to a 100 BAR (1400PSI) pressure washer which totally relies on pressure to clean you will appreciate that there is little pressure and it becomes almost irrelevant in the actual physical cleaning process. The one minor benefit pressure provides is that when you initially release the steam (or vent to atmosphere) you will experience an initial rush of steam at a higher temperature than non-pressurised. After a few seconds the temperature (and pressure) have dropped off to that of a non-pressurised steam cleaner. It’s not until you have stopped exhausting steam that the pressure and temperature will start to build back up again. Pressurised steam cleaners tend to be a great
