Power
The Sun Joe SPX4000
With a 14.5 amp motor, its axial pump delivers a pressure of 2030 PSI (roughly 34 times more than a standard garden hose) and a flow of up to 1.76 GPM, resulting in the Sun Joe SPX4000's cleaning power of 3572.8 Cleaning Units.
The SPX4000 is an electric pressure washer and thus, can be easily started by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.
Design & Handling
The Sun Joe SPX4000 is very mobile, due to its hand truck design and approximate dimensions of D21.2 x W19.3 x H36.6 in. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4000 convenience of transport, while offering a comfortable grip.
Since the unit weighs only 27.8 lbs, it is very easily carried around. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 8" wheels.
