There are important terms for you before you buy a pressure washer:
- GPM( Gallons Per Minute): This is the flow rate of your pressure washer. Most pressure washers have the capability of 1-5 GPM which is normal. More GPM means more cleaning power. That is why pressure washers used ion industrial use has more GPM than household pressure washers have.
- PSI (Pounds Per Square Inch): this is the pushing force of your washer. 1000-3500 PSI is most common among the machines. PSI depends on the nozzle you are using to clean and sometimes on the distance of your machine from surface.
- Cleaning Power: cleaning power means GPMxPSI. Both GPM and PSI are multiplied to calculate a washers cleaning power.
