GPM? PSI? With so many different pressure washers and acronyms out there, it’s hard to decide which one is right for you. Spreetail’s wide selection of pressure washers can help you with everything from washing the car, to blasting away stubborn driveway stains. Check out our handy guide to help you learn the lingoand choose the model that meets your needs.  
 
Defining Pressure Washer Terms 
 
PSI is a term you’ll see on every pressure washer out there. It stands for pounds per square inch and measures the force of the water a pressure washer can produce. Pressure washers push water through a small opening, which increases its pressure and allows you to clean with more force than a standard garden hose can produce. 
 
GPM is used to measure the volume of water a pressure washer uses while running. It stands for gallons per minute. GPM is an important consideration because choosing a model with a higher GPM can mean a higher water bill for you, but a lower GPM washer may not have enough power to handle the tasks on your list. 
 
Pick Your Power 
 
Determining which kind of pressure washer to buy starts with figuring out whether you’d like a model that needs to be plugged in or not. If your cleaning work won’t always take place near an outlet, you should opt for a gas or battery-powered model. Gas-powered pressure washers like this model from Stanley are great for when you don’t want to worry about being tethered to a cord, and you can’t run the risk of a dead battery slowing you down.  However, if you don’t mind a cord, an electric model like this compact Sun Joe pressure washercan help you avoid the gas can with a 33-foot extension cord. If you want the mobility of a gas-powered pressure washer with the quiet volume of an electric model, check out this battery-powered washerfrom Power Products USA, which delivers enough PSI to take care of washing off the car or cleaning the gutters, in a small package that can be easily carried around.  
 
A PSA on PSI 
 
Determining the amount of PSI you need in a pressure washer comes down to the type of work you'll be doing. If you aren’t sure how you'll put your washer to work yet,  for some ideas. Lighter-duty jobs like washing the car or cleaning your grill can be handled by a smaller power washer with a PSI range of 1 to 2,000, , which uses just 0.79 GPM. For medium duty tasks like cleaning the deck, sidewalks, or house siding, you’ll want to look for pressure washers in the 2 to 3,000 PSI range, like this gas-powered Simpson Cleaning 2,400 PSI model that uses just 2.0 GPM and comes with 3 spray nozzles.   
 
Finally, for industrial strength stains and cleaning capabilities, look for a heavy-duty pressure washer with 3 to 4,000 PSI. Models in this range, like DeWalt’s 3,400 PSI unit, are great for tougher jobs like stripping paint off siding, graffiti removal, and stubborn stains.
