The Sun Joe SPX3500 in use

The Sun Joe SPX3500

With a 13-amp induction motor powering it, the axial pump of this unit are capable of achieving a pressure of 2300 PSI (approximately 38 times greater than that of a standard garden hose) and a flow rate of up to 1.48 GPM (values as per CSA testing standards). While these PSI and GPM values represent the maximum capabilities of the washer under specific conditions, it's important to note that under typical usage, the working pressure is 2000 PSI and the flow rate is 1.1 GPM. Corresponding to these values is a cleaning power of 2200 Cleaning Units.

Being an electric unit, the SPX3500 easily starts up with the press of an ON/OFF switch, providing seamless operation. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

Featuring a portable design and approximate dimensions of D16.7 x W14.5 x H36 in, the Sun Joe SPX3500 underscores its dedication to mobility. The handle adds to the SPX3500 convenience of transport.

The weight, largely contributed by its motor, is moderated by Sun Joe's use of a plastic frame, keeping it within a practical range. Despite this, the SPX3500's two solid wheels ensure effortless maneuverability.
