WHAT’S YOUR APPLICATION?

Before purchasing a pressure washer think long and hard about what you intend to use it for

What kind of work will you be doing, building maintenance, equipment wash down, vehicle washing, drain cleaning or general clean up and will it be on a domestic or industrial scale?  How frequently will you be using it: daily, weekly or only a few times a year? Do you need to use cold water, hot water or have chemical injection options?

By understanding the type of cleaning work you’ll be doing, you’ll quickly get a good idea of the type of machine and accessories you need.  You should now know if you need a domestic or an industrial pressure washer and whether it needs to be large and trailer/van mounted or small and compact.

 

Fuel or ElectricityWHAT’S YOUR POWER SOURCE?

Cold water electric pressure washers are great for mid to light duty work, however there are a few drawbacks that your should be aware of. With electric machines movement will be limited to the length of your power cord and electricity is not always available on site. Hot water pressure cleaners are popular for heavy duty and degreasing work, these hybrids use electricity to run and diesel to fire their burners and heat water up to your required temperature. Firebox boilers can be connected to cold water petrol pressure washers and powered by a generator to create a hot water pressure washer.

Diesel and petrol water blasters are designed for heavy duty cleaning around construction sites, on farms and for building wash down work. Petrol water blasters allow freedom of movement and provide enough power to get the difficult jobs done. For the mining industry diesel is the only power source that meets ‘minespec’ requirements. Now take a moment and think about how you’ll use the machine and what the most practical solution is for you.
