A pressure washer (also referred to as a jet washer or steam cleaner, if it is a high-temperature hot washer) is a form of cleaning equipment that uses a high-pressure stream of water to remove dirt, grime, and other stubborn stains from surfaces. 

The high-pressure stream of water is created by a motor or engine that powers a pump. This pump effectively speeds up the water flow through the pressure washer, which is then pushed through the nozzle at the end of a trigger gun and lance. Similar to how you might try to create pressure with your garden hosepipe by squeezing it, the nozzle creates a smaller gap for the water to pass through. The elevated force at which this happens in a pressure washer, however, enables them to create a high-pressure stream of water that can blast away dirt and grime from surfaces such as concrete driveways, patios, vehicles and outdoor furniture.

Pressure washers come in various sizes, from small handheld units for light, often domestic, cleaning tasks to large industrial units for heavy-duty cleaning. They can be powered by electricity, petrol, diesel or other fuels, and the pressure of the water stream can range from 70 to 300+ BAR at a flow rate of 5 - 25+ litres per minute. 

Here at Idro Power, we deal primarily in industrial and commercial cleaners that predominantly operate between 140 - 250 BAR and flow rates of 7 - 20 litres per minute. However, for specialised cleaning, we often build or upgrade rigs that are capable of supporting multiple guns or higher flow rates, such as 30LPM and higher pressures (250+ BAR).

Pressure washers are commonly used for cleaning surfaces and materials in a range of domestic, commercial and industrial settings. For example, they can be used for cleaning vehicles, boats, and other machinery. Or, pressure washers of a higher pressure output can even be used for removing paint or graffiti from surfaces, as well as for preparing surfaces for painting or staining.

TLDR

Pressure (or Jet) washers are powerful cleaning tools that can be used for various tasks. Whether cleaning your driveway, preparing a surface for painting, or removing stubborn stains, a pressure washer can make the job easier and more efficient.
