Keeping your property clean and maintained is critical to its appearance, value and longevity. Among all the cleaning tasks, regular pressure cleaning stands out as the most crucial way to get a thorough and quick clean. Pressure washers are powerful tools that can handle a wide range of cleaning jobs, from removing light dirt on paths to removing stubborn dirt on outdoor furniture and driveways. In this guide, we will look at the benefits of regular pressure washing, types of pressure washers and best practices for use. We will also go into the technical bits of pressure washers like water-cooled motors, powerful aluminium pumps and nozzle attachments so you can make informed decisions.
What is a Pressure Washer?
A pressure washer (also known as a pressure cleaner) is a versatile tool that uses high-pressure water to remove dirt, grime, mould and other contaminants from surfaces. These machines have an aluminium pump that pressurizes water and expels it through a spray gun. The powerful cleaning action of pressure washers makes them suitable for a wide range of cleaning jobs, from light dirt removal on garden furniture to heavy-duty cleaning like removing graffiti or cleaning driveways.
Pressure washers come in different models, from compact for light jobs to full size for heavy-duty jobs. Whether you have moderate dirt on paths, stubborn dirt on outdoor furniture or ingrained dirt on brick walls, knowing what a pressure washer is and how it works is key to choosing the right one for you.
Power Washer Benefits
Using a power washer regularly has many benefits beyond just cleaning. Here are some of the advantages:
- Unbeatable Cleaning Power: Power washers have more cleaning power than you can imagine. Whether you have light dirt, moderate dirt or stubborn dirt, a power washer can do the job. The combination of high pressure and water flow makes power washers great at removing dirt that’s been embedded in surfaces like driveways, garden walls and outdoor furniture.
- Time and Effort Savers: Traditional cleaning methods like using a garden hose and scrub brush can be time consuming and laborious. Power washers are an efficient cleaning process that saves you time and effort for all cleaning jobs. You can clean decks, driveways and house siding in a fraction of the time it would take with manual methods.
- Increased Property Value: Regular power washing increases the curb appeal of your property by keeping it clean and maintained. A clean exterior can make a big difference to the appearance of your home and potentially increase its value. Whether you’re selling your home or want to keep it looking good, power washing is a valuable tool to get that polished look.
- Preventative Maintenance: Dirt, mold and mildew can cause long term damage to surfaces if left unchecked. Regular power washing prevents this damage by removing contaminants before they can do harm. This not only extends the life of your exterior surfaces but also reduces the need for costly repairs down the line.
- Environmentally Friendly Cleaning: Power washers are an eco friendly cleaning solution as they use the power of high pressure water rather than harsh chemicals to remove dirt and grime. This makes power washing a safer option for the environment and the surfaces being cleaned.
Power of a Power Washer
The cleaning power of a power washer is determined by two main factors: pressure (measured in PSI, or pounds per square inch) and flow rate (measured in GPM, or gallons per minute). Together, these two factors decide how well a power washer can clean different surfaces.
- PSI (Pounds per Square Inch): The PSI rating is the force of the water spray. Higher PSI is for removing embedded dirt and heavy duty cleaning, lower PSI is for gentle cleaning of delicate surfaces like glass or painted areas.
- GPM (Gallons per Minute): GPM is the volume of water used by the power washer. Higher GPM is for faster rinsing and more efficient cleaning, ideal for big cleaning jobs like driveway cleaning or industrial cleaning.
Water-Cooled Motors Benefits
Kärcher’s modern pressure washers often come with water-cooled motors that have several advantages over air-cooled ones:
- Longer Life: Water-cooled motors run cooler, so the engine and pressure washer lasts longer. Perfect for residential and commercial use.
- More Efficient: Water-cooled motors perform consistently even after hours of use, great for industrial cleaning or heavy-duty commercial cleaning. The cooling process keeps the engine at the optimal temperature so it won’t overheat.
- Quieter: One of the biggest benefits of water-cooled motors is they are quieter than air-cooled ones. Perfect for residential areas where noise is a concern, so you can clean without disturbing your neighbors.
- Less Maintenance: By keeping the engine cooler, water-cooled motors need less maintenance, so lower operating costs and fewer repairs in the long run. Good for homeowners and businesses alike.
Aluminium Pumps
The pump is the heart of any pressure washer, and using an aluminium pump has several benefits:
- Lightweight and Rugged: Aluminium pumps are both lightweight and rugged, easy to carry and long lasting. Perfect for compact design pressure washers that need to be portable and efficient without sacrificing performance.
- Heat Dissipation: Aluminium is excellent for heat dissipation so that the pump won’t overheat during extended use. This contributes to the overall reliability and efficiency of the pressure washer, so you get consistent cleaning power for any cleaning task.
- Corrosion Resistant: Aluminium pumps are corrosion resistant, so suitable for use in any environment, even with water restrictions or alternative water sources. Corrosion resistant means the pump will remain in good working condition even after being exposed to water and cleaning agents for a long time.
How Do Pressure Washers Work?
Pressure washers suck water from a clean water source (garden hose) and pressurize it through a pump. The pressurized water is then expelled through a spray gun fitted with different nozzle attachments to change the spray pattern and pressure. Here’s the step-by-step process:
- Water Intake: The pressure washer draws water from a connected garden hose or an alternative water source. Some models have a detergent suction hose to mix cleaning agents with the water for extra cleaning power.
- Pressurization: The pump (usually an aluminium pump) pressurizes the water to the desired PSI. The pump is designed to be robust so the water is pressurized efficiently and gives you the cleaning power to tackle any cleaning job.
- Spraying: The pressurized water is expelled through a spray gun which can be adjusted with different spray lances or nozzle attachments. These attachments allow you to change the spray pattern and pressure for the job you’re doing, whether it’s light dirt on garden furniture or heavy dirt on paths.
- Cleaning: The high pressure water removes dirt, grime and contaminants from the surface, high pressure cleaning is fast and powerful. The combination of high pressure and water flow means even the toughest cleaning jobs are done quickly and thoroughly.
