Energy, Speed, And Water

Depending on the circumstances, cleaning can be a tough job. It takes a considerable amount of elbow grease, time, and the proper resources to clean certain types of surfaces. For example, sponges may be ideal for cleaning your kitchen surfaces because they quickly soak up hot water and soap, which can be used to scrub away dirt and bacteria. Certain cleaning brushes require similar amounts of elbow grease to clean the surfaces of your bathtub or the walls of your shower with heavy-duty bristles. But what about jobs that require a bit more than a simple scrubbing tool to wash away dirt and debris?

After a harsh storm or a warm summer, you might have leaves and debris stuck in your roof's rain gutters. Your front cement walkway might be full of slippery moss. The exterior paneling or paint along the sides of your home will get dirty and perhaps moldy with so many season changes. You'll need a single tool like a pressure washer to combat these issues and easily clear away dirt and debris with power and minimal effort from you.

Fueled by either cold or hot water, the pressure washer consists of a water pump powered by an electric motor or gas engine to remove debris, dirt, dust, and other contaminants from hard surfaces and buildings. Depending on the device chosen, the water pressure is typically measured in pounds per square inch, and it is adjustable, concentrated, and regulated by the water pump itself. The pump accelerates ordinary tap water from a faucet to a high level of pressure. That water squirts through a hose at high speeds using a trigger gun pointed at the intended surface.

Pressure washers have five main parts that include a water inlet, an electric motor or gas engine, a water pump, a high-pressure hose, and a cleaning attachment. The water inlet connects the pressure washer to your main water supply and usually has a built-in filter to keep out debris that would otherwise clog the machine. Depending on the size of your pressure washer, it may come equipped with either an electric motor or gas engine to power the water pump. Small pressure washers benefit from electric motors running off a domestic power supply, whereas large pressure washers benefit from gasoline-powered engines when electrical outlets are difficult to find. The water pump is driven at high speeds by the motor or engine. When the engine pulls the pump one way, water is sucked in from the faucet (water supply); when the engine pushes the pump another way, the water is expelled outward in the form of a high-pressure jet. The hose runs from the washer to the cleaning attachment you plan to use.

Unlike conventional hoses, a high-pressure hose is constructed with multiple layers of dense plastic and reinforced with wire mesh materials for extra strength and durability. The cleaning attachment can vary from a simple trigger mechanism operated by squeezing a handle, to a spinning wand or rotating brush. The type of attachment depends on the particular application involved. For example, a spinning brush attachment and a high-pressure water jet could help to clear additional brush and debris from one's rain gutters, as opposed to just using a simple trigger gun. However, the trigger gun may prove more practical for pressure washing dirty shingle siding.

What is the benefit to using water in this way? Water molecules have a certain amount of electrical polarity. With a high degree of kinetic energy from the pressure washer, water can easily hit tough substances like dirt and wash them away quickly.
