Pressure washers are an excellent investment for anyone who wants to clean outdoor surfaces effectively. With a range of different models, brands, and features available in Ireland, it can be challenging to know where to start when looking to buy one. In this buying guide, we will provide you with all the information you need to make an informed decision when purchasing a pressure washer.

Types of Pressure Washers

There are three main types of pressure washers: electric, gas-powered, and commercial.

Electric Pressure Washers

Electric pressure washers are ideal for cleaning small to medium-sized surfaces like cars, patios, and outdoor furniture. They are lightweight, quiet, and easy to use. They come in two variations: corded and cordless. Corded electric pressure washers are more powerful than cordless ones, but they require an electrical outlet to function.

Gas-Powered Pressure Washers

Gas-powered pressure washers are more powerful than electric ones, making them ideal for heavy-duty cleaning tasks like cleaning large driveways, boats, and RVs. They are also more portable than electric pressure washers, as they do not require an electrical outlet to function. However, they are louder and heavier than electric pressure washers and require more maintenance.

Commercial Pressure Washers

Commercial pressure washers are the most powerful of the three types. They are designed for industrial use and are ideal for cleaning large surfaces like parking lots, commercial buildings, and heavy machinery. They are also the most expensive and require professional installation and maintenance.


How to Choose the Right Power Washer for Your Needs

When choosing a power washer, consider the following factors:

  • Cleaning needs
  • Budget
  • Portability
  • Noise level
  • Durability

How to Use a Power Washer: Step-by-Step Guide

To use a power washer, follow these steps:

  1. Choose the right nozzle for the task.
  2. Adjust the pressure and spray pattern.
  3. Start at the highest point of the surface and work downwards.
  4. Hold the spray gun at a 45-degree angle.
  5. Keep the nozzle at a distance of at least 6 inches from the surface.
  6. Move the spray gun in a back and forth motion.
  7. Avoid staying in one spot for too long.
  8. Rinse the surface with clean water.


When choosing a pressure washer, two essential factors to consider are PSI (pounds per square inch) and GPM (gallons per minute). PSI refers to the pressure of the water coming out of the nozzle, while GPM refers to the amount of water flowing through the machine.

The higher the PSI and GPM, the more powerful the pressure washer will be. However, it is essential to choose a pressure washer with the appropriate PSI and GPM for the task at hand. For example, a pressure washer with high PSI and GPM may damage a delicate surface like a car.

Nozzles and Attachments

Nozzles and attachments play a significant role in the effectiveness of a pressure washer. The nozzle determines the pressure and spray pattern, while attachments help to clean different surfaces more effectively.

Some popular nozzle types include 0-degree, 15-degree, 25-degree, and 40-degree. 0-degree nozzles are the most powerful, while 40-degree nozzles are the least powerful but are ideal for delicate surfaces like cars.

Common attachments include surface cleaners, turbo nozzles extension wands, and foam cannons. Surface cleaners are ideal for cleaning large flat surfaces like driveways and patios, while turbo nozzles provide a more powerful and concentrated spray for tough stains. Foam cannons are useful for applying soap and detergent to surfaces before washing.

Hose Length and Material

The length and material of the pressure washer hose are also essential factors to consider. A longer hose will give you more reach and flexibility, allowing you to clean larger areas without moving the pressure washer. The material of the hose can affect its durability and flexibility. Rubber hoses are more durable but less flexible than PVC hoses, which are more prone to kinking and cracking.

Detergent Tanks

Many pressure washers come with a built-in detergent tank, allowing you to apply soap and other cleaning solutions to surfaces before washing. Some models even have multiple tanks for different cleaning solutions. However, if your pressure washer does not come with a detergent tank, you can still apply soap using a foam cannon or a bucket and sponge.

Portability and Storage

Portability and storage are crucial factors to consider, especially if you have limited space in your garage or shed. Electric pressure washers are generally more compact and lightweight than gas-powered ones, making them easier to store and transport. However, gas-powered pressure washers are more portable because they do not require an electrical outlet to function.

Noise Level

Pressure washers can be noisy, especially gas-powered ones. If you live in a residential area, you may want to consider buying an electric pressure washer, which is generally quieter than a gas-powered one. However, if you need a more powerful pressure washer for heavy-duty cleaning tasks, you may have to tolerate a higher noise level.

Price Range

Pressure washers are available at various price points, ranging from budget-friendly to high-end models. Electric pressure washers are generally less expensive than gas-powered and commercial models. However, the price can vary depending on the brand, features, and power output.

Safety Considerations

Pressure washers can be dangerous if not used correctly. Always read the user manual and follow the safety instructions carefully. Wear protective gear like goggles, gloves, and closed-toe shoes when using a pressure washer. Never aim the nozzle at a person or animal and avoid spraying electrical outlets, light fixtures, and other electrical devices.

Tips and Techniques for Effective Cleaning

To get the best results from your power washer, follow these tips and techniques:

  • Use the right nozzle for the task.
  • Adjust the pressure and spray pattern to match the surface.
  • Use hot water for tough stains.
  • Pre-treat the surface with a cleaning solution.
  • Work in sections to avoid missing spots.
  • Use a surface cleaner attachment for larger areas.
  • Use a telescoping wand

How to Clean Specific Surfaces with a Power Washer

Different surfaces require different cleaning techniques when using a power washer. Here are some tips for cleaning specific surfaces:

  • Concrete: Use a 25-degree nozzle and a surface cleaner attachment. Apply a concrete cleaner solution to remove oil stains and other tough stains.
  • Wood: Use a 40-degree nozzle and keep the pressure low to avoid damaging the wood. Test a small area first to ensure the pressure is not too high.
  • Brick: Use a 15-degree nozzle and a lower pressure setting to avoid damaging the mortar between the bricks.
  • Cars and trucks: Use a 25-degree nozzle and a lower pressure setting to avoid damaging the paint. Keep the nozzle at least 1 foot away from the surface.

Maintenance and Storage of Your Power Washer

Proper maintenance and storage of your power washer can prolong its lifespan and ensure optimal performance. Here are some tips:

  • Flush the pump with water after each use to remove any debris or dirt.
  • Store the power washer in a dry, cool place away from direct sunlight.
  • Drain the fuel tank and the carburetor if you have a gas-powered power washer.
  • Replace the oil and air filter regularly.

Common Power Washer Mistakes to Avoid

Avoid making these common mistakes when using a power washer:

  • Using too high of a pressure setting and damaging the surface.
  • Using the wrong nozzle for the task.
  • Staying in one spot for too long, causing damage to the surface.
  • Not using protective gear and risking injury.
  • Not reading the user manual and not understanding the instructions.
