What’s the Most Powerful Electric Pressure Washer?

most powerful electric pressure washers

The pressure washer industry began by accident in 1926. American Frank W. Ofeldt II discovered that steam forced at high pressure through a small hose provided a great way to clean grease off his garage floor.

In 1950, Alfred Kärcher from Germany invented the hot-water high-pressure washer. His son Johannes now owns 50% of the world’s largest privately held cleaning equipment company.

Most homeowners prefer owning an electric pressure washer. They’re easy to store, lightweight, affordable, and require little maintenance.

And many of them pack a powerful punch when cleaning off unwanted stains and grime. Keep reading to find which brand carries the most powerful electric pressure washer on the market today.

What to Look for in the Most Powerful Electric Pressure Washer

Before you buy an electric power washer, it’s important to understand exactly what makes it a good purchase. Here are a few things to look for:

Cleaning Power

Cleaning power is probably the most important factor to consider when buying a new pressure washer. Cleaning power is measured in two ways:

PSI

It’s measured by PSI (pounds per square inch). This measures the cleaning force of the water created through the pressure washer.

This helps you determine how powerful the water stream is on a machine.

GPM

It’s also measured by GPM (gallons per minute). GPM measures the volume of water that’s delivered through the pressure washer.

This helps you figure out how fast the pressure washer can clean. It also helps you figure out how effectively it can rinse away debris.

PSI and GM on Consumer Electric Motor Models

Electric model models range from 1,300 to 1,800 PSI. GPM goes up to 1.5.

These machines are best for light-duty, infrequent jobs such as:

  • Car washing
  • Shutter cleaning
  • Spot cleaning
  • Grills
  • Lawn furniture
  • Light mold and mildew removal

Check to make sure the machine is residential electric grade so it works with your outlets.

Other Features to Look for in Electric Pressure Washers

PSI and GPM aren’t the only features to consider when buying a power washer. Look for a pressure washer that features a ground fault interrupter that’s built into the cord.

Many attachments are made for specific projects, including the extension wands and rotating brushes. Check to see whether the pressure washer nozzles, brushes, and tips all match the types of projects you plan on using them for.

Bigger Jobs May Require EFI

If you require a machine that can handle more demanding jobs, consider buying a unit that includes electronic fuel injection (EFI). EFI gives the pressure washer 50% better fuel economy along with easier starting.

Keep in mind that well water may not be compatible with most washers due to low water flow.

Portability

Do yourself a favor and wheel it around the store before you buy it. You’ll then have a good idea if you can use the washer when you’re by yourself.

Warranty

Always read the fine print of your pressure washer warranty. Find out what it actually covers.

Make sure your warranty covers the engine and the pump rather than just the frame.
