Pressure washers use water pressure to clean various surfaces and are now affordable for families to buy instead of renting. They can increase garden hose pressure by 15-50 times and come in different types, such as gasoline or electric, and cold or hot. The pump inside is important, with higher PSI and GPM ratings indicating more power. Prices range from $200-$500 USD, with more powerful models costing double. Consider the weight when choosing a portable option.
A pressure washer is a machine that can clean many different types of surfaces using water pressure. Pressure washers have been around for several years, but have only recently become so affordable that many families buy them instead of renting them from the local hardware store. Maybe your wooden deck needs cleaning and a repaint, or maybe your concrete porch is scratched and stained. Whatever your problem, a pressure washer is likely to help.
Pressure washers can generate significantly more water pressure than a garden hose. In fact, most of the home pressure washers available for home use actually use your garden hose and its water supply. A pressure washer can increase the pressure in your garden hose 15 to 50 times or more. This increased pressure not only helps clean better, but also reduces the amount of water used.
The primary function of a pressure washer is to multiply the pressure output from a garden hose and concentrate the water into a pressurized stream. The machine does this by using an electric or petrol motor to drive a highly efficient pump. This pump acts as a compressor and allows the pressure washer to deliver a concentrated, pressurized flow of water. After flowing through the pump, the water exits the pressure washer via a hose attached to a long handle that the user controls. A trigger allows the user to spray the pressurized stream in short bursts or in a continuous spray. The intensity of the spray can be adjusted on most pressure washers and is very effective at removing dirt and grime from the surface.
Pressure washers come in different types. Gasoline powered washers are typically rated between 5-7 horsepower and can hold higher pressure than their electric counterparts. Electric washers may be suitable for tasks where you don’t want to blow up the surface you’re working with, but they require more pressure than a garden hose. For example, when you’re washing the windows in your home, using a petrol pressure washer may be providing too much pressure. An electric washing machine would most likely be ideal.
Pressure washers can also be characterized as cold or hot. Cold pressure washers are generally less expensive, but can be less effective at cleaning dirty areas than their hot counterparts.
More important than the power of a washing machine is the pump inside the washing machine. Pumps are rated in both PSI (pounds per square inch), which measures pressure, and GPM (gallons per minute), which measures water flow. When considering a washing machine, be sure to check these specifications. The higher each number, the more powerful the washer will be.
The cost of a pressure washer generally ranges from $200 to $500 US Dollars (USD). If you’re looking for a more powerful model for stripping paint or removing heavy stains and grease, expect to pay about double. Typically, spending more money on a pressure washer will get you a better quality pressure washer, one that has a better pump and better motor, and produces better results.
Keep in mind, however, that the more powerful the washing machine, the heavier it is likely to be. So if portability is an issue, you should find a good compromise between power and weight.
