Zoom on the Sun Joe SPX4600
The Sun Joe SPX4600 is a heavy duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
Using a 14.5 amp induction motor, its axial pump delivers a pressure of up to 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 1.3 GPM. Together, the values result in a cleaning power of 3900 Cleaning Units.
As it is an electric pressure washer, the motor of the SPX4600 gets easily started by a simple 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 SPX4600 offers superb mobility, with a hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4600 convenience of transport, while offering a comfortable grip.
Since the unit weighs only 36.6 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 9.4" wheels.
