Power
The Sun Joe SPX4600
With a 14.5-amp induction motor, its axial pump delivers a pressure of 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 1.3 GPM. 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 2300 PSI and the flow rate is 1.1 GPM, resulting in the Sun Joe SPX4600's cleaning power of 2530 Cleaning Units.
Being an electric unit, the SPX4600 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
With its hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in, the Sun Joe SPX4600 provides great mobility. The sturdy metal frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The foam-padded fixed handle adds to the SPX4600 convenience of transport, while offering a comfortable grip.
With a weight of 36.6 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. Its motor and metal frame account for a good chunk of that weight. Nevertheless, the SPX4600's two 9.4" wheels ensure it remains easy to maneuver.
