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 and fragile surfaces
- use of detergent and cleaning solutions
Its axial cam pump, which utilizes an impressive 212 cc (7 hp) engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to 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
Thanks to its hand truck design and approximate dimensions of D23 x W22 x H43 in, the ECHO PW-3100 offers great mobility. The robust and sturdy steel frame offers longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing 77 lbs, the unit is easy to maneuver by most people. 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.
- Soap injection: Detergent storage is ensured by a 0.92 gal tank. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: Using a set of convenient hooks, the included 25 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
