Zoom on the ECHO PW-3100

- applying detergents or chemicals, and rinsing surfaces afterward
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
With a powerful 212cc (7 hp) engine, its axial cam pump delivers a pressure of 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), resulting in the ECHO PW-3100's cleaning power of 7750 Cleaning Units.
To initiate the Rato R225 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Fuel for the pressure washer is housed in a tank capable of holding up to 0.95 gallon of gasoline.
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 steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 77 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. The main contributors to its weight are its 212cc Rato R225 engine and steel frame. However, the incorporation of two 12" never-flat wheels makes navigating the PW-3100 less cumbersome, even on uneven terrain.
Main Features
The ECHO PW-3100 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: A safe detergent storage is facilitated by a 0.92 gal tank. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with the water flow.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 25 ft ⌀3/8" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: In the table below, you can see the 4 included nozzles alongside their respective recommended surface uses.
