How a pressure washer

There's a good scientific reason why water gets things so clean: its molecules have a slight electrical polarity (one end is positively charged and the other is negatively charged), so they tend to stick to things all by themselves. Detergents (soap chemicals) help water to do its job even better by breaking down gunge and grease and making it easier for water to flush away. But some kinds of ground-on dirt just won't budge, no matter how hard you try. That's when a pressure washer comes in really handy. It uses a narrow, high-pressure jet of hot or cold water to blast dirt free. Because the water is traveling fast, it hits the dirty surface with high kinetic energy, knocking dirt and dust away like a constant rain of tiny hammer blows. It's only water, though, so it doesn't damage most hard surfaces. Having said that, it's a good idea to test a pressure washer on an inconspicuous area before you start work to make sure it doesn't harm the surface you're cleaning. Always read the instructions before you use a pressure washer!
A pressure washer is less sophisticated than it sounds. It's really just a water pump powered by an electric motor. The washer takes in ordinary water from a faucet (that's a tap to you folks in the UK), the pump accelerates the water to high pressure, and then squirts it from a hose at speed through a trigger gun. You can fit various other attachments to the end of the hose for cleaning different things.
This is the tube that runs out from the washer to whatever cleaning attachment you've decided to use. An ordinary bit of tubing wouldn't be able to survive the high-pressure of the water flowing through it. High-pressure hose is reinforced with wire mesh and has two or more layers of high-density plastic. It's important to use hose that has a higher pressure rating than the pump in your pressure washer but, if your washer came with your own hose, there shouldn't be anything to worry about. Typically, the safety margin on pressure-washer hoses is about 300 percent,
 pressure washers have additional features. Water and electricity are not a good mix, so many power washers have ground-fault circuit breakers, also known as residual current devices (RCDs), built into the power supply to protect you in case of an electrical fault. Most washers work in the same way and do exactly the same kind of thing, but the more expensive ones tend to operate at higher water pressures (and have better cleaning power).
