In pressure washing in regards to nozzle size there is one universal principle. This is the fact that if you half the size of the nozzle in diameter, the pressure of the jet stream will double, likewise if you double the size of the nozzle, there will be double the pressure.
This principle should help you determine the type of gun you’d want to purchase And there are 4 settings of pressure washing nozzles:
The 0 degree nozzle shoots a straight jet of water directly on to the surface without causing a fan effect. Purely a stream.
The 15 degree nozzle hits the target with a wider surface area, there fore creating a slight sheet of water. Because the force is spread across a larger area.
The 25 creates an even larger sheet or fan due to having less pressure than the 15.
The 40 degree is the most gentle and wisest spread perfect for cleaning down a window.

Buying a unit for professional use can be at first more expensive as you are purchasing the machine out right however in terms of turn-over, the machine will pay for itself in a few months as long as you take care of it much like a motor vehicle, without proper maintenance, cleaning, oil changes etc… the machine can start to break down.
Pressure washers use a petrol powered or electric motor to power a pump that sends concentrated amounts of water through a small nozzle typically a few millimetres wide in diameter creating a thin jet stream with enough pressure to cut through garden debris, dirt and foliage.
The pressure washing industry can trace its roots back to 1926 and the glory days of prohibition. Frank W. Ofeldt II, an employee of a Pennsylvanian producer of gas-fired water heaters and boilers and a maker of whisky stills, is credited as the inventor of pressure washing. However while working on a whisky still, that he discovered that steam forced at high pressure through a small hose provided an effective method of cleaning grease off his garage floor.

People can suffer Anything from a small cut to a serious laceration through your body and although rare, it could sever a small body part like a finger or toe.
The pressure levels coming from the wand of the washer can be anywhere from 1300-4000psi. To put that into perspective a regular domestic hose you can find in anyone’s back garden can only push out a maximum of around 50psi. That would mean a pressure wash can squeeze out more than 50x times that of a regular hose in pressure.
Not only will it cut, bruise and scar your body. The dirty water can penetrate into the deeper layers of your skin resulting in a nasty infection over time. In fact in 2014 around 6000 people were reportedly sent to hospital due to a pressure washing related injury.
