Zoom on the Powermate 7131
The Powermate 7131 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
Powered by an impressive 208 cc (5.8 hp) engine, its aluminum axial cam pump can deliver a pressure of 3100 PSI (around 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Combined, these values mean that the Powermate 7131 has a cleaning power of 7750 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Generac engine.
Gasoline is stored in a fuel tank with a maximum capacity of 0.87 gallon.
Design & Handling
The Powermate 7131 is very mobile, due to its hand truck design and approximate dimensions of D23.6 x W19.7 x H40.3 in. The strong welded steel frame assures assembly longevity. The foam-padded fixed handle adds to the 7131 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 57 lbs. A major component of its weight are its 208 cc Generac engine and welded steel frame. Nethertheless, thanks to its two 10" never-flat wheels, the 7131 remains very easy to manipulate and maneuver.
Along with the Powermate 7131 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: A safe detergent storage is facilitated by a 0.3 gal tank. As the Powermate 7131 doesn’t include a soap dilution mechanism, the user must provide a correctly diluted detergent before proceeding to use it. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: Using a set of convenient hooks, the included 30 ft ⌀0.3" high-pressure hose (3100 PSI rating) can be easily stored on the unit when it is not running.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
