Zoom on the Powermate 7131
In summary, the Powermate 7131 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
The Powermate 7131's aluminum axial cam pump, powered by a powerful 208 cc (5.8 hp) engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). The Powermate 7131 thus has a cleaning power of 7750 Cleaning Units.
The Generac engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.87 gallon.
Design & Handling
The Powermate 7131 offers superb mobility, with a hand truck design and approximate dimensions of D23.6 x W19.7 x H40.3 in. Its sturdy welded steel frame provides longevity to the assembly. The foam-padded fixed handle adds to the 7131 convenience of transport, while offering a comfortable grip.
With a weight of 57 lbs, the unit can be easily maneuvered by most users. A major component of its weight are its 208 cc Generac engine and welded steel frame. Since the 7131 has a set of two 10" never-flat wheels, it is still easily maneuvered and manipulated.
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: Detergent is stored in a 0.3 gal tank. It must be noted that the Powermate 7131 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. 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 allows for an easy storage of the included classic ergonomic spray gun and its wand.

The Powermate 7131's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Powermate 7131 compare to similarly priced pressure washers.
- Able to deliver a maximum pressure of 3100 PSI, the Powermate 7131 is one of the gas-powered products that produce an above average water pressure, in the $250 to $300 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Powerhorse 89897 with 3200 PSI.
- With a water flow of up to 2.5 GPM (gallons per minute), this washer belongs to the upper end of the above-mentioned price range, as it can deliver a high volume of water. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Powerhorse 89897, with a GPM of 2.6.
- Reaching up to 7750 Cleaning Units (PSI x GPM), the 7131 is one of the more efficient amongst its similarly priced peers. If you consider the highest overall cleaning power as a really important factor, the Powerhorse 89897 and its 8320 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
As you can see from this interactive chart, when compared to other gas-powered washers between 7500 and 8000 Cleaning Units, the Powermate 7131 is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
