The Generac 6922 washer engine

The engine is one of the first things that people look into when considering buying a gas power washer. With Generac 6922 washer, you get an OHV horizontal-shaft engine. The 4-cycle gas engine that works with unleaded gas has two great assets to take into account:

  1. It is manufactured by Generac;
  2. It goes out from the company’s production line in Wisconsin, USA.

To sum up, the unit boasts an USA-made engine with recoil start that supports and generates:

  • 2800 PSI
  • 2,4 GPM
  • 6720 cleaning units

Of course, this particularly performant engine will be nothing without a water pump that will match its powerful traits. Coming up next, more details on all the other technical details, starting with the pump.

Other features of the Generac 6922 washer

We promised to begin with the pump, though the next information might cast some shadow… So, it comes with an axial cam pump, which is said to be perfectly positioned above the ground. At the same level with the engine, for quick and ease connections, it is also well-balanced over the axle. This equilibrium is very important for improving the maneuverability of the entire gas power washer.

The controversial issue here is that the pump is the only component of the Generac 6922 washer manufactured in China. This, of course, can easily turn off everyone trying to stay away from all the Chinese-manufactured products.

Other than that, this product comes with:

  • 3 multi-pattern nozzles and individual tips – 0-degree, 25-degree, 40-degree – plus a separate soap nozzle;
  • Universal quick connect wand/nozzle systems;
  • 5-inch gallon, on-board stored tank for the detergent;
  • 8-gallon fuel tank capacity;
  • 25-foot high-pressure hose easy to connect to the back of the spray gun.

Generac 6922 washer design features

From a distance, the Generac 6922 washer seems to carry a very simple and practical design. The entire package that should be delivered to your front door will weight around 65 pounds. Unpacking will leave you with a 57-pound unit measuring 35.4 x 18.8 x 24.4 inches when fully assembled.

As you will soon discover, it will only require a simple assembly, without any kind of tools. Suffices to clip on the handle and the hook that will hold the hose and you’re done.

Most would agree that this particular model was designed with ergonomics in mind, as it features:

  • Quick-change nozzle tips that snap on very fast and help you to significantly reduce the time between different cleaning tasks;
  • Soft but firm cushion grip handle that enhances the comfort during use;
  • Easy-to-pull spray trigger that will require a minimal effort on your side, thus reducing the fatigue;
  • Stable and easy to maneuver on any kind of terrain, 10-inch never-flat wheels;
  • Compact horizontal-shaft engine with all the connections easily accessible, so you don’t have to kneel on the ground for it;
  • A single, general location for all the controls of the Generac 6922 washer, On/Off, fuel shutoff, choke included.

Ease of use and noise

With all the details provided above, it becomes obvious that this gas power washer is particularly easy to use:

  • Fast hose connection;
  • Fast nozzle tip changes;
  • Easy to pull or push on any kind of terrain;
  • Fast and intuitive assembly;
  • Separate oil and gas tanks that require no mixing together;
  • User-friendly controls all available in a single, common location.

As for the noise level that a Generac 6922 washer can produce, it is pretty low. Low enough to allow you to talk without shouting while it’s working. You will notice that the noise is louder when pulling the hand nozzle and running the engine at higher RPM. But the lever release and the RPM’s drop off will make the sound comparable to the one of a mower. A mower turned on, but without any load on it, to be more specific.

Generac 6922 washer customer reviews

Rated as one of the best choices for household duties, this model enjoys quite a lot of positive reviews. Our readers appreciate the fact that it is a very compact, light and easy to use. So easy that you can tote it up and down the stairs and clean your wooden decks with it.

The engine, with its significantly larger displacement compared to other units, generates a lot of power. It suits to all kinds of chores around the house, provided you’re not looking to perfectly scrub a second-story wall. That’s where some of our readers had to complain of it…

Sure, it has a long hose that should let you get up there. But the performances are lower compared to cleaning on the ground level. Moreover, what is generally an advantage – the lightweight design – can also turn into a reason for discontent. Because it is so light, the unit needs to be held in place when you pull the starter rope. Consequently, some readers would have appreciated a foot peg or something to secure it in place.
