How Do Portable Pressure Washers Work?

Pressure washers work by sending high-pressure water through a pipe directed at the item needing cleaning. As the water is powered through an internal pump it is pressurised to a greater level than could be achieved straight from a tap at mains water pressure. The nozzles at the end of the pipe further constrict the water jet giving it more or less power depending on the nozzle attachment used.

Pressure washers are usually powered by means of an electric cable that’s plugged into the mains socket. And the water is usually supplied via a hose connected to an outside tap. 

Portable pressure washers work on a similar principle but have an onboard water tank to store water, meaning there is no need for an outside tap or any other water supply. There are also cordless pressure washers that don’t need to be attached to the main electricity supply but are powered by a rechargeable battery unit so no electric cables dragging while in use either.

Other types have a hand primer to fill the container with air pressure and this is how the machine is powered. No electricity or batteries to worry about just how much energy you can produce.

What Are The Benefits Of A Portable Pressure Washer

The main benefits of a portable pressure washer is just that – It’s portable, you’re free to use it wherever you like, with no constrictions on power availability or water supply. Simply fill the reservoir up at home after fully charging the battery, and take the pressure washer to wherever you want to wash.

Portable pressure washers can be used in any remote place that you need to take it. And can be used on

  • Caravans
  • Boats
  • Cars
  • Patios
  • Driveways
  • Fences
  • Railings
  • Fascias
  • Sidings
  • Houses
  • Decking
  • Bicycles
  • Motorbikes
  • And anywhere else you can possibly think of.

So the main benefit of a portable pressure washer is its portability, giving you the freedom to wash virtually anything, anywhere at any time that suits you.

What Are The Disadvantages Of A Portable Pressure Washer

There are a few disadvantages to using a portable pressure washer, one is the weight, as they have a water tank on board with a capacity for up to 15+ litres and as each litre of water weighs 1 Kg, added to the weight of the machine, this can be heavy to lug around. That said many have wheels to make moving much more convenient.

Other considerations, all pressure washers are quite noisy. 

Cordless pressure washers only have as much power as the battery can store, and this can limit your cleaning time.
