Description
Zoom on the Generac 8874
The Generac 8874, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Generac 8874
Powered by a 196cc engine, its aluminum axial cam pump can deliver a pressure of 2900 PSI (around 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 8874 has a cleaning power of 6960 Cleaning Units.
This gas-powered pressure washer’s Generac engine is started by a traditional pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.
Design & Handling
The Generac 8874 is very mobile, due to its hand truck design and approximate dimensions of D24.4 x W18.9 x H35.5 in. The robust and sturdy steel frame offers longevity to the assembly. The rubber-padded fixed handle adds to the 8874 convenience of transport, while offering a comfortable grip.
Most users can maneuver this model easily, as it weighs just 57 lbs. One of the largest contributors to its weight are its 196cc Generac engine and its steel frame. The 8874 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.
Main Features
The Generac 8874
The Generac 8874's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. 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 25 ft ⌀1/4" 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.
- Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
0° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | Use with caution | Suitable | Suitable | Suitable |

The Generac 8874's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Generac 8874 compare to similarly priced pressure washers.
- The Generac 8874, which can reach a PSI of 2900, achieves an average pressure output, compared to other gas-powered units that cost between $240 and $300. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Simpson CM61083, which reaches up to 3400 PSI.
- In the aforementioned price range, the GPM (gallons per minute) of this washer, which can reach 2.4, can be considered in the average. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Excell EPW2123100, with 2.8 GPM.
- With the 8874's 6960 Cleaning Units (PSI X GPM), its cleaning efficiency range may be considered average, compared to gas-powered units of similar price. If you consider the highest overall cleaning power as a really important factor, the Excell EPW2123100 and its 8680 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
