Zoom on the Generac 7122

The Generac 7122 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • cleaning of painted and fragile surfaces
  • applying detergent and cleaning solutions

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

Power

The Generac 7122 in use

The Generac 7122

Powered by a 196 cc engine, its brass axial cam pump can deliver a pressure of 3200 PSI (around 53 times more than a standard garden hose) and a flow of up to 2.7 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 7122 has a cleaning power of 8640 Cleaning Units.

The Generac engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D24.2 x W18.9 x H35.5 in, the Generac 7122 offers great mobility. The robust steel frame guarantees longevity of the assembly. The rubber-padded fixed handle adds to the 7122 convenience of transport, while offering a comfortable grip.

Weighing 62 lbs, the unit is easy to maneuver by most people. Its 196 cc Generac engine and steel frame account for a good chunk of that weight. However, the two 10" never-flat wheels allow the 7122 to be easily manipulated and maneuvered.

Main Features

The Generac 7122 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is stored in a 0.5 gal tank. It must be noted that the Generac 7122 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: Using a set of convenient hooks, the included 30 ft ⌀1/5" high-pressure hose (3400 PSI rating) can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included PowerDial spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

Some of the accessories of the Generac 7122

Some of the included accessories

  • PowerDial™ gun: The PowerDial™ ergonomic spray gun features 4 different power modes, which can be selected simply, according to your cleaning task – soap, wood, concrete or car.
  • Soap Blaster: The Soap Blaster attachment achieves a 3x longer spraying distance than a standard nozzle tip, allows you to penetrate tough stains and improves your overall cleaning results.
  • Power Broom: Generac’s Power Broom features a 12” surface coverage with high pressure nozzles, which are up to 4x faster than standard nozzles. It performs excellently when cleanings deck, patios, driveways and sidewalks.

  • Pressure control: Water pressure can be manually changed, using the adjustable throttle of the trigger gun.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
  • Accessories: On top of an owner's manual and the usual documentation to get you swiftly started, the Generac 7122 also comes with pressure hose, funnel, Power Broom attachment, Soap Blaster nozzle, spray gun, wand and oil.
  • Emissions: The Generac 7122 is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
