Pressure Washers Introduction

Welcome to your guide to the world of pressure washers

Here you will find out everything you ever wanted to know about pressure washers, but were afraid to ask.

Pressure washers are sometimes called power washers, jet washers or steam cleaners. They project a powerful hot or cold jet of water (and cleaning chemicals or detergent), at pretty much any surface that needs to be cleaned. They have many uses around the home and are frequently bought for agriculture, industry and business use including;

Cleaning cars to showroom standards

Washing mud off tractors and machinery

Cleaning chewing gum off pavements

Cleaning pollution off buildings

Degreasing engines

Washing ships and boats

Removing moss and dirt from patios or driveways

Restoring wooden decking

Valeting cars

Cleaning windows

In fact they have thousands of uses around the home and business.

There are three main types of pressure washer based on how they are powered -

Diesel Pressure Washers	Petrol Pressure Washers	NorthStar Petrol Pressure Washers	Electric Pressure Washers

Broadly speaking electric ones are lighter weight and aimed at domestic users, whereas petrol and diesel pressure washers are intended for heavy duty use in business, agriculture or industry, though there are a huge number of models with overlapping specifications.

All pressure washers work as follows ;

1) Taking low pressure water from the mains (or with attachments from a standing water tank

2) Increasing the pressure and/or temperature using electric, diesel, or petrol powered engines

3) Pumping the water through a high pressure lance (either with or without chemicals or detergent)

4) Finally forcing the water through a pressure nozzle for powerful cleaning action.

Pressure Washers can therefore be compared by: The amount of water that flows through them LPH or LPM (Litres per hour/per minute)

The pressure of water produced in PSI (Pounds per Square Inch) or BAR. Higher pressures provide tougher cleaning, but be careful to test the area to be cleaned to make sure it is not going to damage it. NOTE: PSI is quoted with the lance on the same level as the pressure washer. Running the hose up hill will reduce the pressure at the tip.

Good quality pressure washers will be supplied with non-marking hoses which won't leave black marks on concrete or other surfaces that have just been cleaned, the way standard hoses can. Many pressure washers can also be used with attachments like a hard surface cleaner, rotary wash brush, wall or gutter cleaner, or an under-car cleaner, making them even more versatile.
