We know: All About Pressure Washers

What are pressure washers?

Pressure or power washers are devices that pump water under high pressure through a hose usually connected to an outside faucet. Sometimes they mix the water with a cleaning solution. They are usually powered by a gasoline engine or an electric motor and have a wand or spray nozzle attached to the end of the hose.

What do you use a pressure washer for?

You can use a pressure washer for a variety of things. Depending on the size and model you buy, pressure washers can be used to wash:

House exteriors, including porches and decks
Loose paint from exterior siding
Vehicles, including cars and trucks
Heavy equipment, such as farm equipment
Windows and awnings
Barbecue equipment
Driveways
Swimming pools and spas

What kinds of pressure washers are there?

Both light duty engines that are good for jobs around the house, and heavy, industrial sizes.

How much do they cost?

Pressure washers start at about $250 for smaller, household models, and can cost over $1000 for heavier duty models.

Are there any hazards?

Electric power washers combine electricity and water and can be dangerous. Here are some precautions to take when using an electric power washer, suggested by the Consumer Product Safety Commission:

Always plug a three-wire grounded pressure washer into a properly grounded receptacle.
If an extension cord must be used, keep the power cord connection out of any standing water, and use a heavy duty, three-wire, properly grounded type. Keep the connection as far away as possible from the item being washed and away from any water runoff.
Wear rubber-soled footwear that provides some insulation when operating the pressure washer.
NEVER cut or splice the power cord or extension cords.
NEVER remove the grounding prong from the power cord plug!
NEVER operate the pressure washer after it has tripped a ground fault interrupter or circuit breaker without first having it examined for electrical faults by a competent repair person.
