What the AI looks for in Pressure Washers
- Flow vs. pressure
- Compare GPM as well as PSI; cleaning speed tracks flow (PSI × GPM is the common combined measure) High PSI with low flow cleans slowly.
- Power type
- Electric for cars, decks and patios; gas for large concrete, siding and paint prep Electrics are lighter-duty but low-maintenance.
- Nozzles
- Standard 0/15/25/40-degree and soap tips with 1/4-in quick-connect fittings Standard fittings let you add surface cleaners and replacement tips.
- Pump
- Axial pumps for occasional use; triplex pumps for frequent heavy use Triplex pumps last far longer under load.
- Hose
- Check hose length and kink resistance Short or stiff hoses force constant moving of the unit.
