Further down the page, you'll find some explanations regarding the key similarities and differences between the Generac 7122 and the Generac 7143.
But before checking out explanations regarding their power, design, and features here's a table that summarizes the main pros of each of these 2 pressure washers:

Power Comparison
- Fuel: Both units are gas-powered pressure washers.
- Engine & Pump: The Generac 7122 and the Generac 7143 both use an axial-type pump to put water under pressure. These 2 pumps are manufactured by Annovi Reverberi. The pump on the Generac 7122 is powered by a 196 cc engine, while the Generac 7143 uses a 173 cc engine. While these two devices can both start thanks to a conventional pull-start mechanism, the Generac 7143 has the advantage of also being able to get running via a convenient electric starter.
The following charts are provided to show you at a glance how the main specs of the Generac 7122 compare to the Generac 7143.
- Pressure: With very similar maximum reachable pressures (3200 PSI for the Generac 7122 and 3100 PSI for the Generac 7143), both devices should do an equally good job at lifting and blasting off dirt.
- Water Flow: When operating at low pressure, the 7122 can generate a higher maximum volume of water than the 7143. It can deliver up to 2.7 GPM (gallons per minute), whereas the 7143 offers a maximum water flow of 2.5 GPM. The former should thus allow you to rinse away dirt and debris with better efficiency and speed.
- Cleaning Power: With its 8640 C.U. (Cleaning Units = PSI x GPM), the Generac 7122 offers a higher overall cleaning efficiency than the 7143 and its 7750 C.U.
Design Comparison
- Design: Both units are constructed with a hand truck design. Therefore, if either of these 2 devices should provide better mobility, it would be due to its wheels and weight (which we detail just below).
- Weight: With an approximate weight of 58.1 lbs, the 7143 is slightly less heavy than the 7122 (which weighs around 62 lbs).
- Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a rubber-padded handle, which improves your grip when you wish to move them.
Feature Comparison
- Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. Whether you choose the 7122 or the 7143, you'll be able to store your cleaning chemicals in the unit's onboard soap tank. Their soap capacity is equal, as the tanks of both units can hold 0.5 gal of detergent.
- Trigger Gun & Wand: Each of these 2 units comes with a PowerDial trigger gun and a classic wand.
- Nozzles: Both pressure washers come with 0°, 25°, 40°, and soap nozzles, but the nozzle similarities stop here. The 7122 also has a turbo nozzle.
- Reach: Both products include a 30 ft high-pressure hose. Therefore, neither of them will, out of the box, allow for a higher freedom of movement around the unit.
- Storage: The 7122 and 7143 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers feature a set of hooks to help you neatly store their high pressure hoses when not in use.
- Accessories: In addition to the standard set of included accessories, both units also come with Power Broom and Soap Blaster.
