Zoom on the Generac 6712
In summary, the Generac 6712 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
Powered by a powerful 302 cc engine, its triplex pump can deliver a pressure of 3800 PSI (around 63 times more than a standard garden hose) and a flow of up to 3.2 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 6712 has a cleaning power of 12160 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 1.7 gallon.
Design & Handling
The wheelbarrow design of the Generac 6712 grants mobility and stability to the unit. Its sturdy steel frame provides longevity to the assembly. The handle adds to the 6712 convenience of transport.
At 134 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The major reasons for its heavy weight are its 302 cc Generac engine, the triplex pump and steel frame. However, the unit is mobile thanks to its two 10" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.
Along with the Generac 6712 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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The Generac 6712 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The 50 ft ⌀5/16" high-pressure hose (4000 PSI rating), which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
|Concrete, brick, masonry||Use with caution||Suitable||Suitable||Suitable||Suitable|
|Siding, gutters, house||Not recommended||Use with caution||Use with caution||Suitable||Suitable|

Note: The shape of the nozzles above is for illustration purposes only and may differ.

- Onboard storage: The Generac 6712 allows you to be always fully prepared, as it features a handy storage area, where nozzles and accessories can be stored.
- Safety: Safety of operation is enhanced by a low oil protection, a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Generac 6712 comes with soap hose, oil, wand, pressure hose and spray gun.
- Emissions: The Generac 6712 is NOT CARB-compliant and so you cannot buy it nor sell it in California.
The Generac 6712's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Generac 6712 compare to similarly priced pressure washers.
- The Generac 6712, with a maximum pressure output of 3800 PSI, has an average pressure output, when considering gas-powered units in $825 to $900 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the DeWalt DXPW4440 with a PSI of 4400.
- In the aforementioned price range, the GPM (gallons per minute) of this washer, which can reach 3.2, can be considered in the average. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Generac 6565, with a GPM of 4.
- The 12160 Cleaning Units (PSI x GPM), of the 6712 result in an average cleaning efficiency, compared to similarly priced gas-powered units. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the DeWalt DXPW4440 and its 17600 Cleaning Units.
As you can see from this interactive chart, when compared to other gas-powered washers between 11200 and 13300 Cleaning Units, the Generac 6712 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.
