This pressure washer comes equipped with a Honda gasoline engines. Anyone who is familiar with Honda knows that their engines are highly reliable. Please note, this is not a Honda pressure washer with a cheap pump, but rather a Simpson pressure washer with a Honda engine. That means that you don’t have to worry about the quality of either the pump or engine. The engine is direct-drive coupled to the triplex pump for simplicity. The pump itself it made with ceramic pistons, which both dissipate heat better and are less affected by it. There is also a thermal relief valve for safety. This unit will pump 2.8 GPM of water at 3200 Psi, making it the most powerful one on this list. It is also equipped with a downstream injection system for cleaners or solvents.
Generac 659B, 31000 PSI 2.7 GPM Gas Pressure Washer
This pressure washer from Generac is just a little bit smaller than the Simpson that I selected for first place, but it’s considerably less expensive. Generac builds their own engines to power these pressure washers. The pump and engine are directly coupled and mounted directly over the axle for ease of movement. While it uses an axial pump, it is still rugged and designed to last. The hose connections are easily accessible, without having to kneel on the ground. This unit comes with two detergent bottles, allowing you to continue working while refilling one. The controls are mounted on the handle for ease of operation. They've even included a holder for the cleaning wand.
Pressure Pro Eagle Electric Series EE2015G
The Pressure Pro Eagle EE2015Gg is an electric pressure washer, equipped with a 2 HP, 18 Amp motor. It will provide 2.0 GPM of water at 1,500 PSI. The big advantage of this over the gas powered units is that it is much quieter, allowing it to be used indoors, if needed. The pump itself is a triplex plunger for long life; and it can be rebuilt. There is a thermo sensor to prevent overheating in bypass mode, but no low oil protection. This unit comes with a 5 year warranty for either home or commercial use. The pressure is adjustable and there is a siphon system for chemical injection.
NorthStar is Northern Tool & Equipment’s brand. This 1.5 GPM, 2000 PSI pressure washer runs off a Leeson electric motor. The motor is high efficiency, saving energy and the rotor is dynamically balanced for low vibration. The pump itself is a high quality Cat triplex pump with ceramic plungers. The direct drive configuration reduces parts and maintenance. Chemical injection is also included on the unit.
Although this list is for consumer pressure washers, I've included this industrial unit, which can do double-duty as a consumer model. The main reason that it is considered an industrial unit is the durability of the pump. This is a hand carried unit, as opposed to the others we've looked at, which are all mounted on wheeled carts. That makes it more compact for storage but a little harder to use. The unit is powered by a 1.7 HP induction motor and the pump will operate at either 1350 PSI or 1800 PSI as you select. A thermal switch is included to protect the pump from heat damage. A Three foot chemical pickup hose is provided, so that you can put it right into the chemical bottle, rather than having to dump the chemicals into the unit’s tank.
