Description

Zoom on the Generac 7901

In a nutshell, the Generac 7901 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
  • soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
  • utilizing cleaning solutions, and rinsing surfaces clean

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Its axial cam pump, which utilizes a 196cc engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.4 GPM. Corresponding to these values is a cleaning power of 7440 Cleaning Units.

Initiating the Generac engine of this gas pressure washer is achieved through a classic pull-start process.

Fuel for the pressure washer is housed in a tank capable of holding up to 0.8 gallon of gasoline..

Design & Handling

Thanks to its hand truck design and approximate dimensions of D24.4 x W18.9 x H35.5 in, the Generac 7901 offers great mobility. Guaranteeing longevity, the robust steel frame offers stability and protects internal components, even when subjected to demanding tasks. The rubber-padded fixed handle adds to the 7901 convenience of transport, while offering a comfortable grip.

Weighing 57 lbs, this unit offers a manageable weight that allows for easy handling by most individuals. The unit's weight is principally a result of the inclusion of the 196cc Generac engine and a strong steel frame. However, with its two 10" never-flat wheels, the 7901 remains highly maneuverable.

Main Features

Along with the Generac 7901 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: The pressure washer features a 0.5 gal tank for detergent storage. However, since the Generac 7901 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
  • Pressure hose: Utilizing a set of convenient hooks, the unit offers a convenient solution for storing the included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) when it's not in use, keeping it neatly organized.
  • Spray gun and wand: A side hook allows for an easy storage of the included PowerDial spray gun and its wand.
  • Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.

  • Pressure control: Water pressure can be manually changed, using the adjustable throttle of the trigger gun.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: The Generac 7901 comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get spray gun, wand, oil, funnel and pressure hose.

The Generac 7901's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Generac 7901 compare to similarly priced pressure washers.

  • Featuring 3100 PSI, the Generac 7901 achieves a lower pressure value compared to competing gas-powered pressure washers within the $400-500 price category. Prioritizing the highest water stream power? Check out the Simpson PS61201—a top contender in this price range, delivering up to 3500 PSI.
  • This washer, with a GPM of 2.4 (gallons per minute) has a somewhat lower water flow value compared to devices in its price range. When it comes to efficiently rinsing away debris, one standout option within this price range is the Lifan LFQ3370E, delivering an impressive 3 GPM.
  • The 7901 has 7440 Cleaning Units (PSI X GPM), which can be considered low in comparison to other gas-powered devices of this price. If the highest overall cleaning power is your top priority, the Lifan LFQ3370E, which can reach up to 9900 Cleaning Units, is one of the most efficient of the devices in the current price range.
