Hi Bill! The different PSI ratings for the WORX - Hydroshot 40V Electric Pressure Washer up to 585 PSI at 0.9 GPM (2 x 4.0 Ah Batteries and 1 x Charger) WG644 will be determined by the water source used. If using the included 20' draw hose you can expect an approximate PSI of 450 because only the WG644 motor is supplying the force. If using a garden hose as the water source, you can get as much as 585 PSI since the garden hose will give its own additional force to the water. -Grace J.
