Pressure washers are power cleaning tools that clean by blasting water at a high pressure.
Many pressure washers let you adjust the pressure that water is delivered at. Higher pressures will clean faster but keep in mind that different items will have a different tolerance to water pressure. Water at too high a pressure can cause damage. Water pressure is measured in bar.
Pressure washers have many potential applications in the garden.
For safety, wear protective goggles and shoes when operating a pressure washer.
