Components of pressure washers

  • High pressure washers or cleaners (both Karcher and Sterwins) include:
  • Two nozzles: normal and turbo (increases the power by 50%).
  • Flexible hose between 2 and 12 meters. The machines of greater power incorporate hoses reinforced with metallic mesh that are more durable.
  • The pump head (which connects the hose to the water inlet) can be made of steel, aluminum or brass. The latter is the one that offers more quality.
  • Wheels to make your movement easier.
  • Detergent tank If it is not integrated in the machine, one external to the lance can be attached.
  • It can be electric or gasoline.

What to consider before choosing a pressure washer?

For my needs and what size? Before opting for one model or another we must take into account the following aspects:

  • Hose length: The length of the hose varies between 2 and 12 meters. Models with longer hose offer more work autonomy without having to move the machine.
  • Power: Hydro cleaners have a power ranging from 1300 to 3000 w.
  • Electric or gasoline model: The electric ones require an outlet, while the gasoline ones provide more autonomy.
  • Water-cooled electric motors, as well as induction motors, extend the life of the machine and provide greater durability.
  • Pressure: At a higher level of use, a higher pressure (bars) will be necessary. 1 bar equals 1 kilo of pressure / cm2.
  • Occasional use: bicycle cleaning, garden furniture and balconies – between 100 and 110 bars
  • Moderate use: cars, walls and outdoor floors up to 30 m2 – from 110 to 120 bars
  • Frequent use: facades, swimming pools, roofs and outdoor floors up to 40 m2 – from 120 to 140 bars
  • Intensive use: facades, swimming pools, roofs and outdoor floors up to 60 m2 – up to 160 bars

Maintenance tips

Although high pressure machines work with cold water, some admit hot water inlet up to 40ºC, and some models even up to 60ºC.

The degreasing power of hot water is greater than that of cold water; However, experts advise not to exceed the admission of hot water because it can damage some of its parts (valves, seals, seals …) and use a specific detergent to increase the anti-grease force of cold water.
