The ECHO PW-3100 is a gas-powered pressure washer offering a maximum water pressure of 3100 PSI and flow of 2.5 GPM. (Read full specs)
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, paintless surfaces and reaching far-away areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
With an impressive 212 cc (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.
The Rato R225 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline is stored in a fuel tank with a maximum capacity of 0.95 gallon.
Design & Handling
The ECHO PW-3100 offers superb mobility, with a hand truck design and approximate dimensions of D23 x W22 x H43 in. The robust steel frame guarantees longevity of 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. Its 212 cc Rato R225 engine and steel frame account for a good chunk of that weight. Since the PW-3100 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.
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: Detergent storage is ensured by a 0.92 gal tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: The included 25 ft ⌀3/8" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

The following charts are provided to give you an idea of how the key specs of the ECHO PW-3100 compare to similarly priced pressure washers.
- The ECHO PW-3100, with a maximum pressure output of 3100 PSI, has an average pressure output, when considering gas-powered units in $400 to $500 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Generac 6924 with 3600 PSI.
- Considering its water flow, this washer, with a GPM (gallons per minute) of 2.5 is in the average compared to other devices in its price range. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Lifan LFQ3370, that can deliver up to 3 GPM.
- In comparison to other gas-powered units of similar price, the 7750 Cleaning Units (PSI x GPM) of the PW-3100 are average. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370 and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
