Complete Guide to Buying a Pressure Washer

Do you want to make outdoor cleaning projects faster and easier? Using a pressure washer does just that, but how do you know what kind of washer to get? With many options out there, it’s hard to choose what’s best for you and your next job, so we’ve put together some things to consider when looking for a pressure washer.

Pressure washers are simple. They use pumps, either gas or electric, to amplify water pressure. Water enters the machine from a garden hose through a low-pressure connection, then runs through the machine's high-pressure hose that connects to a pressure washer wand and is sprayed out through a nozzle.

A pressure washer’s power is measured by the pressure output or pounds per square inch (PSI) and gallons per minute (GPM). The higher the rating the better and faster the pressure washer will clean. Consider your projects at hand to determine how powerful of a washer you need.

Light-duty (Consumer):

Usually rated between 1300 and 1900 PSI at 2 GPM, are best for smaller, more delicate jobs around the house. Ideal for cleaning the car, patio furniture, and grills. Electric pressures are best for this kind of work.

Medium-Duty (Semi-Pro):

Rated between 2000 and 2800 PSI at 2-3 GPM. These washers tend to be gas powered, they are studier and more powerful making it easier to clean siding, fences, decks and driveways.

Heavy-Duty (Professional):

Rated 2800 or higher PSI at 3-4 GPM, are built with a stronger, more durable engine and pump, for everyday use. Use this type of washer for large-scale jobs like cleaning a 2 story building, removing graffiti or stripping paint.

There are different kinds of attachments you can get for your pressure washer to help with specific types of cleaning:

• Surface Cleaners (pictured above) – These feature spinning jets that provide deep cleaning on driveways, sidewalks, decks, and patios.
• Brushes – These help scrub away dirt and grime without damaging delicate surfaces like cars, boats, and windows.
• Angled Wands – Designed for cleaning hard-to-reach areas, like gutters, wheel wells, and under vehicles.
• Foam Cannons – For applying thick layers of soap or detergent. Perfect for washing cars, siding, and outdoor furniture.
• Extension Wands – Increase reach, making them useful for tall houses, second-story siding, and roofs without needing a ladder.
• Water Brooms – WIth multiple nozzles in a row, water brooms help quickly clean large flat surfaces like garage floors, driveways, and patios with consistent pressure.

Cost Considerations

Pressure washer prices vary based on power, features, and brand. Light-duty electric models are the most affordable, while high-powered gas models cost significantly more due to durability and performance. It’s important to know your budget and projects you’ll need your pressure washer for to select the best model for you. If you need accessories like longer hoses, extra nozzles, and surface cleaners, that will add to the overall expense as well.

Cordless Pressure Washers

Cordless pressure washers are also an option if you don’t need something heavy-duty or your budget doesn’t cover a gas or electric pressure washer. Cordless power washers run on rechargeable batteries, making them portable and easy to use without outlets. They are ideal for light cleaning tasks like washing bikes, or surface-level dirt, but typically have lower PSI and shorter run times compared to electric or gas-powered models.
