Description
Zoom on the Generac 7143
The Generac 7143 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 or delicate 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 7143
Its aluminum axial cam pump, which utilizes a 173 cc 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 2.5 GPM. These values correspond to a cleaning power of 7750 Cleaning Units.
The Generac engine provides a convenient and reliable start of this gas-powered pressure washer, with a dual start mechanism: you may choose the more convenient electric start, or the classic pull-start mechanism. A 12V Lithium-ion battery, which is included in the package, is required for the electric start.
Gasoline is stored in a fuel tank with a maximum capacity of 0.3 gallon.
Design & Handling
With its hand truck design and approximate dimensions of D24.4 x W19 x H35.5 in, the Generac 7143 provides great mobility. The strong welded steel frame assures assembly longevity. The rubber-padded fixed handle adds to the 7143 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 58.1 lbs. Its 173 cc Generac engine and welded steel frame account for a good chunk of that weight. But, as the 7143 does have a set of two 10" never-flat wheels, it can be easily maneuvered and manipulated.
Main Features
Along with the Generac 7143 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: A safe detergent storage is facilitated by a 0.5 gal tank. It must be noted that the Generac 7143 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: A neat storage for the included 30 ft ⌀1/5" high-pressure hose (3400 PSI rating) is facilitated by a set of convenient hooks.
- Spray gun and wand: The included PowerDial spray gun and its wand can be easily stored in a side hook.
- Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.
0° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | Use with caution | Suitable | Suitable | Suitable |
| Siding, gutters, house | Not recommended | Use with caution | Suitable | Suitable |

The Generac 7143's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Generac 7143 compare to similarly priced pressure washers.
- Reaching a 3100 PSI max pressure output, the Generac 7143 has an expected pressure value, compared to the other gas-powered units in the $400 to $500 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Simpson MS60921-S, which reaches up to 3300 PSI.
- This washer reaches 2.5 GPM (gallons per minute) and thus, has an average water flow compared to similarly priced devices. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Lifan LFQ3370, that can deliver up to 3 GPM.
- As the 7143 has a total of 7750 Cleaning Units (PSI X GPM), it finds itself in the average cleaning efficiency range for similarly priced gas-powered units. If the highest overall cleaning power is your top priority, the Lifan LFQ3370, which can reach up to 9900 Cleaning Units, is one of the most efficient of the devices in the current price range.
