Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
Its axial pump, which utilizes a 14.9 amp induction motor, may deliver a pressure of up to 2350 PSI (almost 39 times more than a standard garden hose) and a flow of up to 1.8 GPM. These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 2000 PSI and rated flow is 1.1 GPM. These values correspond to a cleaning power of 2200 Cleaning Units.
As it is an electric pressure washer, the motor of the SPX3550 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.

With its portable design and approximate dimensions of D15 x W17 x H36 in, the Sun Joe SPX3550 makes mobility one of its core strengths. The handle adds to the SPX3550 convenience of transport.
With a weight of only 24 lbs, the unit is definitely easy to carry around. Its plastic frame certainly plays a key role in this light weight. To further improve its transportability and ease of use, the unit also features a set of two solid wheels.
