A Pressure Washer is a device consisting of two to four high-pressure jets on a rotating bar that swivels when water is flowing. This action creates a uniformed cleaning pattern that can clean flat surfaces at a rapid rate.

These cleaning devices are mostly powered by either electric motors or gasoline engines. The gasoline-powered ones tend to be bigger and louder while the smaller ones are usually electrically powered and a little bit quieter.

If you own a messy business and you have a big clean job to do or if you’re just looking for a little help cleaning around your beloved home, a pressure washer can change your life.

Pressure Washers can be used to ease your life and stop you from using useless harsh chemicals while cleaning backyards, decks, driveways, patio furniture, etc.  

To be highly-efficient, a pressure washing device needs 1900 to 2800 cleaning units. The recommended pressure is around 1200-1900PSI with 1.4-1.6GPM.

The difference between a power washer and a pressure washer is that the power washer heats up the water, using warm or hot jets, while a pressure washer does not. It uses the cold, normal faucet water and can be used on heat sensible surfaces. 

If the attachment has narrow nozzles, the pressure of the water jet increases allowing you to focus on a smaller spot, but if it has wider nozzles instead, the pressure decreases, covering a bigger area.

Contrary to popular belief, a pressure washer uses only around 2 gallons of water per minute while a garden hose can use up to 20 gallons per minute. It’s a great way to save water if your water is metered.

While pressure washers tend to be noisy and messy, blasting the dirt in all directions if not used properly, they’re of great help when it comes to major cleaning. With a small investment, you can improve your life for years to come.

The GPW1800 Electric Pressure Washer is not recommended to be used on light-duty cleanings like cars and windows. They are made with concrete cleaning in mind.

This pressure washer is powered by a 13Amp universal motor that generates 1800PSI and 1.1GPM for maximum cleaning power. It can easily remove stubborn grime and annoying dirt.

With the help of 5 different quick-connect nozzles and various other attachments, you can clean a wide range of surfaces. There’s a 40°, a 50°, a 0°, a soap and a turbo nozzle included in the box, easing the job as much as possible.

Depending on the task you’re focused on, you can match the proper water pressure jet for better efficiency, with the interchangeable wands the washer comes with.

Things to know

The Axial cam pump that is maintenance-free makes the Greenworks GPW1800 Electric Pressure Washer perfect for homeowner use.

If you’re planning on cleaning everything at once, you have convenient onboard storage for the utensils you’ll be using during the cleaning, allowing you to keep them within reach. It can hold the spray gun, power cord, spray tips, etc.

For you to be able to move it wherever you need it to be, as easily as possible, the washer is designed with two big 8-in wheels and a rugged metal-frame for strength and durability.

Pressure Washers use a special detergent. While normal soap can be great for light cleaning, it won’t help much in stubborn areas. Thanks to the onboard soap tank, you don’t have to apply the detergent by hand on the surfaces you’re planning to wash.

With the turbo nozzle, you can clean various surfaces with more power, helping you get the job done faster, easier and more importantly, cleaner.

The GPW1800 Electric Pressure Washer is meant for horizontal surfaces, making it more difficult to try and hold it against a vertical surface (a fence by example). The power of the spray is what keeps it off the surface and it might not be evenly applied.

This Pressure Washer is specifically designed to be used mainly on flat surfaces, like driveways, decks, patios. The bristles are soft, and it’s just a thin ring around the outer perimeter. They’re not flexible or designed to be used on vehicles. They do have rotary brushes for vehicle surfaces that you can buy separately.

All Greenworks pressure washers are PWMA-certified. PWMA, aka the Pressure Washer Manufacturers Association, was developed in 1997 to set standards for pressure washers.
