What is a pressure washer?

A pressure washer is a tool that connects to your outdoor spigot and delivers a powerful, high-pressure stream of water through a cleaning nozzle. These cleaners provide a fast and efficient way to clean driveways, patios, tiles, concrete, cars, bikes and more.

Why should I consider a pressure washer?

The main advantage of using a pressure cleaner is that if you need to give a dirty, muddy or moldy area a deep clean, it’s much quicker and easier than a hose, bucket and scrub brush.

You can use a pressure washer for a wide range of cleaning jobs, including:

• Removing oil stains and dirt from concrete
• Blasting moss and slime from tiles and patios
• Hosing dried mud off your car
• Cleaning outdoor furniture
• Prepping surfaces for painting

What types are available?

• Electric pressure washers

  Electric models are usually a good choice for most homeowners because they’re generally easier to use and maintain than gas-powered washers. They’re affordable, don’t require too much maintenance and have enough power to tackle a wide range of cleaning jobs around the home.

  However, they plug into your home outlets so you’ll need to deal with the hassle of lugging around a power cord and possibly an extension cord.

• Gas-powered pressure washers

  If you want extra power to tackle bigger cleaning tasks, or you simply don’t want to be tethered to an extension cord, you may want to consider a gas-powered washer. They’re suitable for heavy-duty work and use in remote areas because they’re more portable and more durable than electric washers. However, they’re noisier and heavier than electric models, need fuel and require more upkeep.

• Battery-powered pressure washers

  Though less popular than the first two options, a few manufacturers offer battery-powered models. They can be convenient and easy to use, and the battery might be able to run several other garden tools from the same manufacturer. However, battery-powered models often can’t offer the same power as the other options.

How to compare pressure washers

Cost is probably one of your top considerations when buying a pressure washer. You can pick up an entry-level electric model for around $50, but most units sit within the $100 to $600 price range.

As a general rule, the more money you spend, the more cleaning power you’ll get. Gas-powered pressure washers start at $300 and go up to around $2,000 for an industrial-grade model.

There are many additional factors you should take into account when buying a pressure washer. Here’s what to consider:

• Nozzles and attachments

  Some manufacturers provide an all-in-one adjustable nozzle to change the angle and force of the spray, while others provide a set of interchangeable nozzles. Check what nozzles and attachments are included and what surfaces they’re best for cleaning. Regular options include pinpoint spray, a wide fan nozzle and turbo nozzle.

  Also consider what brushes the pressure washer comes with to help you scrub your back deck, wash your car, clean drains or perform other specialist tasks. For example, a patio cleaner attachment can be an extremely useful inclusion if you have a large outdoor area to clean.

• Pressure and flow rate

  There are two key factors that determine the cleaning power of a pressure washer: water pressure and flow rate.

  Check the maximum water pressure for any unit you’re considering. For reference, 1,600 to 2,500 pounds per square inch (psi) is a common range for electric-powered pressure cleaners. Some models feature an LED display to allow you to easily check the pressure setting you are using.

  Check the maximum-rated flow as well, measured in gallons per minute. Electric units are commonly between 1.5 and 2 gallons per minute.

• Hose length

  Check the length of the hose that runs from the body of the cleaner to the spray lance. The longer it is, the easier the machine will be to use.

• Lance

  Also known as the spray wand, this directs the spray onto whatever surface you’re cleaning. Metal wands are more durable than plastic ones, and it’s important the wand is long enough for you to reach the ground without stooping.

  Some models come with extension wands for jobs like cleaning second-story windows, and angled wands that can work with an extension wand to clean gutters.

• Storage

  Some models incorporate storage space for the lance and hose in the unit so they take up less room in your shed or garage.

Detergent

Most pressure washers feature some sort of detergent injection system for increased cleaning power.

Portability

Most electric and battery-powered pressure washers weigh somewhere between 10 and 50 pounds, but gas-powered models are usually heavier. Check the weight quoted on the specs sheet to make sure you’ll be able to comfortably maneuver the unit around as you clean.

A unit with large, sturdy wheels will make it easier to move around and negotiate obstacles as you clean.

The longer the power cord on an electric model, the easier it is to clean without having to change outlets or fight an extension cord. Most cords run 15 feet or longer.

Automatic shut-off

This feature ensures that the washer only sprays water while you depress the trigger, allowing you to move from place to place and navigate obstacles without spraying water this way and that. A safety lock on the trigger will also ensure that you don’t accidentally start spraying.

Running time

If you’re considering a battery- or gas-powered model, check how much cleaning you can expect to finish before you run out of juice.

Warranty

Check the length of the manufacturer’s warranty and exactly what it covers. Most will offer at least two years of protection.

Which pressure washer is best for me?

To decide the best pressure washer for your needs, you’ll need to consider exactly how you plan on using it.

Pressure washing tips

There are a couple of important things to remember before using a pressure cleaner:

• Stay safe. Pressure washers are seriously powerful machines and should always be used with caution. Getting in the way of a misdirected spray, particularly when the nozzle is on the narrowest setting, could do serious damage and lead to a trip to the emergency room.
• Be careful with paint. When using a pressure washer on your home or car, be careful not to damage the paint. Follow the manufacturer’s instructions and always err on the side of caution when setting the water pressure.

Bottom line

Investing in a pressure washer can make your everyday cleaning much easier and maybe even a little more fun. Choose the model that’s the best fit for your cleaning needs by comparing the size, weight, power and price before you buy.

Frequently asked questions

• What's a good pounds per square inch for a pressure washer?

  The higher the pounds per square inch, the more powerful the machine and the more cautious you need to be when operating it. Pressure washers can range from around 1,200 pounds per square inch to 2,800 pounds per square inch.

• Is it safe to use a pressure washer on a car?

  Yes, but with caution. Choose a low-pressure setting — somewhere around 1,200 to 1,900 pounds per square inch — and a wide spray nozzle, rather than a narrow, direct stream.

• Can I run hot water through my pressure washer?

  Only if your pressure water is rated for hot water. Otherwise, hot water will damage your pump over time.
