Things to consider when buying a pressure washer:
- Power source. You’ve got a few choices here:
- Gas-powered. These pressure washers are the most powerful and offer the best of both world: mobility as well as great PSI and clean.
- Electric-corded. Electric pressure washers offer solid power but come with the hassle of having to deal with an extension cord.
- Battery-powered. Very portable but not as powerful as the others. You’ll also have the risk of running out of battery power unexptectedly.
- Pressure. Measured in PSIs (pounds per square inch). This is the power or strength with which the water is coming out of the washer. The higher the number the more power the machine has and the cleaner the job it does. You can buy a machine with pressure as low as 1000 PSI or as high as 4500 PSI and above.
- Water consumption measured in GPM (gallons per minute). This is the amount of water coming out of the pressure washer. GPM works hand in hand with the PSI. The higher the numbers, the more power the machine has and the cleaner result you can expect. Pressure washer water consumption can be as low as 1.5 GPM and less or 4.5 GPM and more.
