A pressure washer is a tool with two to four high-pressure jets mounted on a rotating bar that swivels as water goes through it.

This movement produces a constant cleaning pattern that can be used to quickly clean flat surfaces.

They use electric motors or gas engines to power a pump that pressurizes water from your garden hose to 1,000 pounds or more before forcing it out through a spray wand.

Pressure washing, also known as power washing, is the method of using a high-pressure water spray to clean surfaces and objects such as automobiles, buildings, and concrete surfaces to remove loose paint, sludge, chewing gum, dust, mildew, dirt, and filth.

A mechanical pressure washer’s volume is measured in gallons or litres per minute and is usually fixed.

A pressure washer’s high pressure has a few drawbacks, one of which is the danger of damaging the external body.

It can not only harm the paint, but also cause a dent, and repairing automobile paint and dents can be costly. This is particularly true if the water pressure is not properly adjusted.

Advantages of Pressure Washer

  • One of the best things about pressure cleaning your surfaces is that it can do almost anything. You may use it on practically any exterior surface, such as a back deck or driveway, or even the siding of your home, to make it seem brand new, just like the day you moved in.
  • They are quite simple to use. Even if you’ve never used a pressure washer before, it doesn’t take long to find out how to use one.
  • One of the most advantageous aspects of using a pressure washer is that it speeds up the cleaning process by at least five times.

Disadvantages of Pressure Washer

  • Even if you connect your pressure washer to your garden hose and use the water from the hose, the force of the water from an ordinary hose is no match for a pressure washer.
  • Not only can the power of the water damage you, but a pressure washer is distinct from a hose in that it is a machine.
    As with any machine, you must carefully study the user instructions to use it properly and avoid injury from the machine part itself.
  • They are quite powerful and maybe too much for some surfaces to handle.
    Exterior surfaces, such as loose vinyl siding or loose wood, cannot withstand all of the strain and may begin to decay or break off, and may even split under the weight of the load. If your surface is painted, the pressure washer can damage the paint and cause it to peel off.

Applications of Pressure Washer

  • Window washing
  • Drain, duct and gutter cleaning
  • Pool cleaning
  • Chimney sweep services
  • Parking lot and driveway washing
  • Other outdoor maintenance cleaning activities, and

How to Clean Patio Slabs with a Pressure Washer?

Step1        

Remove all furniture, ornaments, and pots from your patio and sweep it clean.

Step2            

Brush away any loose material, such as leaves and dirt, with a broom.

Step3

Before you begin, connect your hose and make sure there is plenty of water flowing. Allow water to run through the machine to flush out any airlocks.

Please keep in mind that the hose must be at least 7.5 metres long and 12 inches thick. If you’re using a hose reel, make sure it’s completely unwound and free of kinks to guarantee a consistent flow of water. Two universal connections and a tap adaptor for your garden tap will be required to connect your hose.

Step4

Connect your pressure washer to the main power source and turn it on to pressurize the system.

Step5

Before you begin cleaning your patio, you could apply detergent to the surface to assist breakdown grime and making the patio simpler to clean.

Some detergents also have specific qualities that will help avoid future filth build-up while also protecting your surfaces from weather damage. There are detergents made specifically for stone, wood, and cars, each with specially designed formulae to suit the purpose.

Step6         

Some dirt and organisms, like lichens, are difficult to remove with a normal lance or patio cleaner.

Most pressure washers come with a rotary pencil jet nozzle, which may generate up to 80% greater power.

By switching to this lance, you can assure that even the most obstinate filth is eliminated. It is crucial to note that due to the higher force of these lances, they should only be used on hard surfaces such as stone or masonry; sensitive materials such as wood or vehicle paintwork may be harmed if cleaned with this type of lance.

Safety Tips

  • Keep an eye out for the initial blast of water that comes out of the pressure washer when you turn it on. There may be a strong initial spray, so aim the nozzle at the ground first.
  • When cleaning block paving or between slabs, never use a rotating (or tornado) nozzle attachment since it is too powerful and could harm the points between them.
  • Use caution when using a powerful spray-on chipped paving, as it may cause additional damage.
  • While you should only need to clean your patio once a year (one of the benefits of choosing a patio versus decking), a little bit of upkeep will ensure a consistently clean finish all year.
  • One wise piece of advice is to remember to brush your patio regularly, especially during the autumn months. This should keep crushed leaves from piling up and generating those pesky discoloration streaks in the spring.
