Zoom on the ECHO PW-3100
In a nutshell, the ECHO PW-3100 is a heavy duty, commercial pressure washer that allows:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted or delicate surfaces
- use of detergent and cleaning solutions
Using a powerful 212 cc (7 hp) engine, its axial cam pump delivers a pressure of up to 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 7750 Cleaning Units.
The Rato R225 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.95 gallon.
Design & Handling
The ECHO PW-3100 is very mobile, due to its hand truck design and approximate dimensions of D23 x W22 x H43 in. Its sturdy steel frame provides longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
With a weight of 77 lbs, the unit can be easily maneuvered by most users. One of the largest contributors to its weight are its 212 cc Rato R225 engine and its steel frame. Since the PW-3100 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.
The ECHO PW-3100's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
